DISCUSSION OF THE RECEIVED RESULTS

In spite of the fact that now there are numerous newest methods of treatment of patients of a stomatologic profile, prevalence of partial and full loss of the teeth, the raised erasability of a teeth, parodontita and occlusion pathologies remains high (Kuzmina D.A.

from co-workers., 2010). In this connection, questions of treatment of patients with the given diseases are rather actual (Iroshnikova E.S. from co-workers., 2009; Piotrovich A.V. from co-workers., 2013).

As there is a close interrelation between a structure visochnoyonizhnecheljustnyh joints, functions of the nervously-muscular apparatus cheljustnoyolitsevoj areas and character smykanija dentitions, development of dentoalveolar anomalies and deformations is accompanied by its transformations. In this connection prevalence of dysfunction VNCHS arising in a considerable quantity of cases as complication of the basic okkljuzionno-caused disease, remains enough high (Serikov A.A., 2013).

Given multilevel morfofunktsionalnoe and clinical research has been spent by us for the purpose of improvement of technology of treatment of patients of a stomatologic profile with the okkljuzionno-caused diseases of the chewing apparatus.

In the first part of work for acknowledgement of an urgency of a theme of dissertational research we study prevalence okkljuzionno - the caused diseases of the chewing apparatus at adult people during the various age periods. It is necessary to notice, that in the accessible literature the term «the okkljuzionno-caused diseases of the chewing apparatus» practically does not meet. Such concepts as «occlusal disturbances», «okkljuzionno-articulation disturbances» are more often used, «deformations of dentitions» are more rare (Longvinjuk I.F., 1990).pri it is absent about what diseases it is necessary to carry a common opinion to the given group.

In our opinion, the uniform sign uniting okkljuzionno - the caused diseases, is disturbance smykanija dentitions - occlusions which leads to changes of functional characteristics of the chewing apparatus and development of new diseases, in particular, to occurrence zuboalveoljarnyh deformations, parafunction of masseters and dysfunction of temporally-nizhnecheljustnogo joint.

In the spent research it is offered to carry partial and full loss of the teeth, the raised erasability of a teeth to group of the okkljuzionno-caused diseases, anomalies of an occlusion and the diseases accompanied by change of the basic apparatus of teeth (parodontit and a parodontosis of serious degree). One of the general lines of the given diseases is change of height of the bottom department of the person, accompanied morfofunktsionalnymi changes of masseters and development of dysfunction VNCHS (Vojtjatskaja I.V. from co-workers., 2013).

According to some authors (Longvinjuk I.F., 1990), to occlusal disturbances it is accepted to carry also anomalies of a separate teeth (density, wrong position), caries, and also consequences of incorrectly restored anatomic form of a teeth and prosthetics without correction of occlusal disturbances. However we have counted inexpedient to unite to them under concept of the okkljuzionno-caused diseases since caries is the most frequent etiological factor of occurrence of partial and full loss of a teeth. Complications of the spent stomatologic treatment are already secondary pathological processes since they arise after development of the basic okkljuzionno-caused disease though replacement of firm tissues of a teeth plombirovochnymi materials or orthopedic treatment, as well as any other interventions in maxillofacial area, are always accompanied by change of occlusal mutual relations of dentitions.

Thanks to carrying out of the complex analysis of medical cards of stomatologic patients we obtain the data testifying about
Presence of gender and age differences in prevalence okkljuzionno - the caused diseases at adult people. So, the maximum prevalence of partial loss of a teeth (53,1 %) is observed in group of II period of mature age at women, the maximum prevalence of full loss of a teeth (34,2 %) - in group of senile age also at women. The greatest percent of the raised erasability of a teeth is characteristic for women of advanced age (21,5 %).

As to a pathology parodonta, the given diseases, on the contrary, meet at men is more often. So, prevalence parodontita reaches the greatest value at persons of senile age, especially at men (77,2 %). The similar picture is characteristic as well for a parodontosis, however its occurrence several times is less, than at parodontita and does not exceed 1,5 %.

The question on influence of a pathology of an occlusion on development of dysfunction VNCHS to sir pores is discussed. S.A.Zizevsky (1989), A.N.Sidorenko (2000) notice, that at the heart of dysfunctions VNCHS the various pathology of an occlusion which gradually leads to disturbance koordinirovannoj works of all components of the chewing apparatus that causes change of movement of a mandible in all directions lays. According to A.V.Adonevoj from co-workers. (2011), occlusion changes cause the minimum disturbances in VNCHS, but as a result of long unusual movements of a mandible degenerate changes in one or in both joints can develop. However in some works the statement about an occlusal genesis of dysfunction VNCHS is exposed to the given reason criticism (to Ivasenko G. SH from co-workers., 2007) as cases of development of diseases VNCHS are proved at intact dentitions, in the presence of infectious process, diseases of internal organs, a chronic psychotrauma etc. (Shvyrkov M. B. From co-workers., 2011; Bulycheva E.A. from co-workers., 2013; BarbosaT.S. et al., 2011).

At full loss of a teeth and high degree of erasability of a teeth practically always arise morfofunktsionalnye changes in VNCHS, in
Result of that its dysfunction (Ryzhak G. A from co-workers develops., 2011; Samsonov V.V., 2012; Kim M.R. et al., 2002).

For revealing of correlations between the okkljuzionno-caused diseases of the chewing apparatus and development of dysfunction VNCHS we had been spent studying of medical cards of the stomatologic patients parted on different age groups.

During the carried out research by us it is established, that in group of the first period of mature age dysfunction VNCHS is taped at 28 persons from 70 surveyed (in 40 % of cases). Among them there were 4 patients of dentitions free of defects, 17 patients had partial defects of dentitions, however orthopedic well-founded designs of prostheses were only at 7 of them, 4 patients suffered generalised parodontitom and 3 - raised

Erasability of a teeth.

In group of the second period of mature age the similar picture was observed. In the given age group dysfunction VNCHS has been taped at 32 persons from 68 surveyed (in 47,1 % of cases). Thus 30 persons with dysfunction VNCHS had partial defects of dentitions, 2 - full. From them signs generalised parodontita were observed at 5 persons, the raised erasability of a teeth - at 12 persons (7 men and 5 women).

Among people of advanced age dysfunction VNCHS has been taped at 42 persons from 68 (61,8 %). Thus in the given group 32 persons, full - 10 persons had partial loss of a teeth. However only at 12 of them defects have been filled by dentoprosthetic designs. Also it is necessary to notice, that among the persons of advanced age who had signs of dysfunction VNCHS, 34 persons suffered generalised parodontitom or the raised erasability of the teeth accompanied by reduction of interalveolar distance.

In group of senile age symptoms of dysfunction VNCHS have been taped in 81,2 % of cases (at 52 persons from 64 surveyed). Partial defects of dentitions had 37 persons, and full - 15 persons. And only at 15 of them the given defects have been filled by high-grade designs of the tooth
Prostheses. Reduction of interalveolar distance at the expense of generalised parodontita and the raised erasability of a teeth was observed at 27 persons with signs of dysfunction VNCHS.

Thus, it is established, that at women dysfunction visochnoyonizhnecheljustnogo a joint meets in 55,8 % of cases, at men - in 44,2 %, thus correlation presence between the okkljuzionno-caused diseases of the chewing apparatus and development of dysfunction VNCHS. At patients of all age groups most often dysfunction VNCHS develops in the presence of partial or full defects of the dentitions which have been not restored by tooth prostheses, and also generalised parodontita and the raised erasability of a teeth. However, as becomes obvious at deeper analysis, in group with dysfunction VNCHS there are patients with intact dentitions. At the same time in group without signs disfunktsionalnoj symptomatologies meet patients the loss of the teeth which have been not restored by rational tooth prostheses, or restored, but orthopedic designs of inadequate quality. The received results can give different interpreting. First, proves to be true polietiologichnost dysfunctions VNCHS; secondly, it is possible to make the assumption, that some patients have well expressed kompensatorno-adaptive mechanisms which are not supposing developments of dysfunction VNCHS even in the presence of okkljuzionno-caused disease (it is possible, features mjagkotkanyh joint structures); thirdly, it is necessary to consider possible errors of diagnostics. The appreciable percent of not diagnosed pathology VNCHS at inspection of stomatologic patients with the okkljuzionno-caused diseases is taped at the analysis of medical cards of out-patient patients and described in corresponding section.

For revealing of principal causes of occurrence of dysfunction VNCHS at the diseases united under the term okkljuzionno-caused, by us it is spent complex kraniologicheskoe research of the basic components of dentoalveolar system: the top, bottom jaws and it is temporal-nizhnecheljustnogo
Joint. The special attention in the given aspect was given to change of anatomic formations at loss of a teeth.

V.N.Trezubov (2006) carries reduction of interalveolar height to the reasons causing changes in visochnoyonizhnecheljustnom a joint, first of all. Therefore detailed studying of high-rise characteristics of the top and bottom jaws in groups with an intact occlusion, partial and full loss of a teeth was an integral part of our research.

Also in the given section the big attention was given to change of a thickness alveljarnogo a process top and bodies of the mandible at loss of a teeth. The received data are necessary for an anatomic substantiation of restoration of integrity of dentitions by means of modern methods implantologii.

As a result of the carried out research by us it is established, that all studied morfometricheskie parametres of an alveolar process of the top jaw essentially change at loss of a teeth. So, at full absence of a teeth there is an authentic reduction of its height at different levels: at level lateralnogo edges of a piriform opening, an infraorbital foramen and skuloverhnecheljustnogo a seam. Thus the greatest value of height of an alveolar process of the top jaw at loss of a teeth are observed in area lateralnyh incisors and canines (at level lateralnogo piriform opening edges) - 12,4±1,2 mm, the least - in the field of molar tooths (at level skuloverhnecheljustnogo a seam) - 7,0±0,9 mm. Average value of the given indicator in group with full absence of a teeth make 8,8±0,7 mm.

Changes of average value of a thickness of an alveolar process of the top jaw at loss of a teeth are not so appreciable. If average value of a thickness of a bottom edge of an alveolar process in group with a full set of a teeth made 8,8±0,3 mm, and value of its maximum thickness 12,9±0,3 mm in group with full absence of a teeth of value of the given indicators have decreased accordingly to 7,3±0,6 mm and 8,3±0,7 mm.

By us it is established, that the greatest changes of height of an alveolar process of the top jaw at loss of a teeth are observed in the field of premolar tooths and molar tooths. In group with an intact occlusion of value of the given indicator have made 14,0±0,4 mm at level of an infraorbital foramen and 13,8±0,6 mm at level skuloverhnecheljustnogo a seam. In group with full absence of a teeth their appreciable reduction to 7,1±0,9 mm and to 7,0±0,9 mm accordingly was observed. At the same time, changes of the given parametre at level of incisors (at level lateralnogo piriform opening edges) not so are appreciable.

According to V.N.Trezubova from co-workers. (2002), special value at loss of a teeth has reduction of height of a body of the mandible in the field of molar tooths as they carry out lateral protection of a joint. With loss of lateral protection all force of muscular reductions is transferred on a forward teeth and VNCHS, initiating an overload of the last, that as a result leads to development of dysfunction VNCHS. In the research carried out by us the analysis morfometricheskih mandible characteristics has shown, that at loss of a teeth of change of height of an osteal tissue of its body also are more essential in the field of molar tooths.

It is necessary to notice, that at loss of a teeth, it is necessary to survey separately branch and body of the mandible changes as the first make immediate impact on VNCHS and cause pathological shift of a head of a mandible in a mandibular fossa; the second - lead to disturbances of an occlusion and limit possibilities of orthopedic treatment of loss of a teeth.

In our work it is proved, that authentic reduction of height of a body of the mandible at full loss of a teeth occurs at all levels: at level of a mandibular symphysis, the middle of a premental segment, the middle of a postmental segment, at mental foramen level. On the average, the height of a body of the mandible at full absence of a teeth decreases on 9,6±0,8 mm and in 25,5 % of cases makes only 10-15 mm. The least value of height of a body of the mandible at full loss of a teeth are observed in the field of molar tooths (the middle of a postmental segment) - 16,1±1,7 mm, the greatest - in
Areas of incisors (in the field of a mandibular symphysis) - 23,4±1,8 mm. Thus if the given sizes to survey with reference to inquiries practical implantologii it is possible to ascertain, that stomatologists not so much full height of a residual bone, how many distance from an upper edge of a body of the mandible to the top wall of its channel interests. Taking into account it, according to results of research, it turns out, that restoration of integrity of dentitions in the field of molar tooths is interfaced to the appreciable difficulties bound to shortage of height of a body of the mandible and augmentation of risk of damage of the bottom alveolar nerve at non-observance of topography of the channel.

On our data, least problems arises at the equipment implantatov in forward department of a mandible where the height of a residual bone is sufficient, and the risk of damage of the channel of a mandible is absent. Foreign authors also specify in it (Burns D. et al., 1995; Bijlani M., Lozada J., 1996).

As shows our research, at loss of a teeth there are essential changes of a thickness of a body of the mandible: the greatest changes arise in the field of canines and molar tooths: value of a thickness of an upper edge of a body of the mandible at level of the middle of a postmental segment decrease at full loss of a teeth from 9,6±0,2 mm to 7,3±0,8 mm, value of a thickness of an upper edge of a body of the mandible at level of the middle of a premental segment from 8,5±0,1 mm to 6,1±0,9 mm.

At loss of a teeth also there is an authentic reduction of the maximum thickness of a body of the mandible on the average on 3,6±0,4 mm.

Now in the accessible literature the attention to change of an angle of an inclination of a body of the mandible practically is not paid at loss of a teeth. By us it is shown, that its value are naturally enlarged in a direction from an average line to a jaw branch. Data on size of an angle of an inclination of a body of the mandible at loss of a teeth, represent special interest for implantologii. The equipment dentalnyh implantatov without the given parametre can lead to that in the field of an apical part implantata will not be sufficient
Quantities of an osteal tissue for its high-grade bracing in a bone. Only in V.V. Razdorskogo's works from co-workers. (2010) there are statements, that application implantatov with thermomechanical memory of the form is impossible at coal of an inclination of a body of the mandible more than 20 ° at use of lamellar designs and more than 30 ° - at the equipment of cylindrical designs.

As the change description only high-rise and shirotnyh characteristics of an alveolar process top and bodies bottom jaws at loss of a teeth cannot be considered complex, and the received data sufficient for planning of competent stomatologic treatment of patients with use of modern methods of restoration of integrity of dentitions, in the spent work we also had been studied features morfometricheskih characteristics of genyantrums at loss of a teeth.

By us it is proved, that at loss of a teeth besides changes of an alveolar process of the top jaw there is an essential change of a structure of genyantrums, and, first of all, degrees of their pneumatization. According to the received data, giperpnevmatizirovannye sinuses in group with an intact occlusion met in 62,5 % of cases, in group full absence of a teeth - in 87 %. The share gipopnevmatizirovannyh sinuses has authentically decreased from 25 % in group with intact dentitions to 4,1 % in group with full absence of a teeth.

In the spent research it is shown, that in group of man's skulls irrespective of a condition of an occlusion of value of width of a sinus there were more than similar value in group of female skulls on the average on 4,0±0,2 mm, and value of its height - on 3,6±0,2 mm. In addition estimating features of the form and degree of a pneumatization of a genyantrum on the turtles parted on value verhnelitsevogo of the index, it has been established, that at leptoprozopov most often meet gipopnevmatizirovannye sinuses; at euriprozopov - giperpnevmatizirovannye.

For fuller representation about the changes occurring in an osteal tissue of jaws at loss of teeth, it was studied arhitektonika their osteal tissue in various groups of skulls. For an estimation of quality of an osteal tissue it was spent
Ordering of skulls from various it arhitektonikoj on classification U. Lekholm and G. Zarb (1985).

According to V.S.Speransky (1988), the alveolar process of the top jaw is constructed mainly of spongiform substance which settles down between external and internal compact plates, and also is a part of interalveolar and interroot septums. The parity of compact and spongiform substances of the top jaw is unequal. So, the share of compact substance in an osteal tissue of an alveolar process makes 27­30 %, and spongiform - 70-72 % (Busygin A.T., 1962). The quantity and a parity of these types of the organisation of an osteal tissue varies throughout all human life. V.N.Ginali (1966) also has shown changes of quantity of spongiform and compact substances depending on loss of a teeth.

In the research spent by us it is established, that in group with full absence of a teeth most often met III and IV class arhitektoniki an osteal tissue of an alveolar process of the top jaw - in 35,5 % and 52,1 % accordingly. In group a full set of a teeth most often there was II class, however its occurrence on the top jaw was a little bit more low, than on bottom and has made 59,3 %. The share I, III and IV classes has made 5,1 %, 27,8 %, 7,8 % accordingly.

In A.T.Busygin's works (1962) it has been shown, that in various parts of a mandible the parity of compact and spongiform substance is unequal. The greatest clumps of spongiform substance are available in a head and a jaw neck, and also in the top part of a body of the mandible and the bottom third of its branch (Speransky V. S, 1988). Appreciable change arhitektoniki an osteal tissue of jaws for the account of reduction of density of a trabecular network occurs at depression of a functional load after loss of a teeth. Lateral departments of jaws as the spongiform layer directly depending on a masticatory stress there is well developed, transferred through a teeth on an osteal tissue are subject to more essential changes. Less appreciable izmenenieja
arhitektoniki bones are shown in forward department of a mandible which is a mandibular symphysis and contains basically a compact layer.

In the research spent by us in group with full absence of a teeth (POSES) in a body of the mandible met mainly II and III classes of quality of a bone. Their share has made 37,3 % and 53,4 % accordingly. In 4,3 % of cases in group of POSES there was I class; IV class - in 5 % of cases. In group an intact occlusion (IP) most often there was II class - in 66,2 % of cases, III class - in 12,2 %, I class - in 20,4 % and is the most rare - IV class - in 1,2 %.

According to V.N.Ginali (1966), spongiform substance of a head of a mandible on the structure melkojacheistoe, diameter of its cells averages 1120±132 micron. On horizontal microsections of a beam of spongiform substance have the roundish form and are bridged among themselves by thin crossbeams.

By us it is established, that at loss of a teeth the maintenance of spongiform substance in a mandible head that promotes its hardening is enlarged, however the structure of an osteal tissue also essentially changes. At full absence of a teeth the following type of its structure is observed: the thin compact layer surrounds spongiform substance with the lowered durability trabekul. These transformations lead to change of the form of a head that is one of major factors of development of dysfunction VNCHS. It is not excluded, that at persons with partial and full absence of a teeth of change of structure of an osteal tissue of jaws are bound also to its age reorganisation. With the years there is a transformation of a red osteal brain in yellow, the osteal tissue becomes quaggy, its blood supply decreases (Thedens E., Lippert H., 1973). As specify C. Bassetti, B. Spiessl (1976), age change of a bone and its osteoporosis more expressed at women, also lead to depression of durability osteal trabekul.

According to given to E.N.Onopa (2005), at partial absence of a teeth depression of height of the bottom department of the person becomes perceptible, reduction of relative optical density of an osteal tissue of a head of a mandible and raised it rezorbtsija is observed. Developed in the subsequent the functional
Disturbances in temporally-nizhnecheljustnom joint promote progressirovannnomu to depression of relative optical density of a cortical plate and spongiform substance of a bone of a head of a mandible.

As has shown our research, at the okkljuzionno-caused diseases there are close correlation communications between structure changes temporally-nizhnecheljustnogo joint and jaws. Reduction or augmentation of some parametres of the top or bottom jaws lead to shift of a head of a mandible concerning its habitual position in a mandibular fossa.

Morfometrichesky researches have confirmed, that at loss of a teeth there is a reduction sagittalnogo and cross-section diameters of a head of a mandible, and value of the first decrease for 4,6 mm, and the last on 2,8 mm, that is the sizes characterising joint bugorok, on the contrary, have average value of height articulate bugorka in group with an intact occlusion make 13,3±0,2 mm, in group with full absence of a teeth - 9,1±0,4мм. Average value of projective height articulate bugorka decrease from 11,2±0,5 mm in group IP to 7,2±0,4 mm in group of POSES. It is necessary to notice, that change articulate bugorka there is an irregular change of the sizes of a head of a mandible. Similar character of changes. So, at loss of a teeth has very important clinical value as its height and the form play a basic role at an articulation (Iordanishvili A.K., 2007).

As articulate bugorok forms forward border of a mandibular fossa becomes obvious, that its depth directly depends on degree of its expression. By us it is established, that depth of a mandibular fossa at loss of a teeth decreases. It, first of all, is bound to some uploshcheniem articulate bugorka. So, if in group of skulls with an intact occlusion average value of depth of a mandibular fossa made 8,6±0,3 mm, in group of skulls with full absence of a teeth - 6,0±0,4 mm. At studying of changes of the frontback size of a mandibular fossa some is taped
Augmentation of this size in groups with partial and full absence of a teeth, in comparison with the intact occlusion, however the given changes are statistically not authentic.

Acknowledgement of observations of transformation of articulate surfaces VNCHS is change of their form at the okkljuzionno-caused diseases. So, a mandible head at full absence of a teeth in most cases (61,3 %) have konusovidnuju the form characterised insignificant sagittalnym in diameter and a narrow neck. Oval and bobovidnaja forms of a head of a mandible are characteristic for an intact occlusion, at full absence of a teeth meet less often. It is necessary to notice, that the oval form of a head of a mandible meets at an intact occlusion (59,9 %), and bobovidnaja - at partial absence of a teeth (45,1 %) is more often.

By us it is proved, that at loss of a teeth there is also an authentic change of the form articulate bugorka and a mandibular fossa. As is known, Z.P.Schmidt (1963) allocated three forms articulate bugorka: flat, average and abrupt. JU.A.Gladilin (1969) allocated two forms of a mandibular fossa roundish and oval. In A.A.Serikov's dissertational research (2013) uniform classification of forms articulate bugorka and a mandibular fossa is developed. As in the research spent by us it was not revealed statistically authentic differences under the form of a mandibular fossa between groups with various degree of safety of dentitions, we offer the classification including the form both articulate bugorka, and a mandibular fossa simultaneously. According to this classification, there are S-shaped and flat their forms. At the S-shaped form it is expedient to allocate three subtypes: 1 symmetric S-shaped form of an articulate surface of a temporal bone at which the sizes articulate bugorka and a mandibular fossa correspond as 1:1, 2 - the asymmetrical S-shaped form of an articulate surface of a temporal bone at which the sizes articulate bugorka and a mandibular fossa correspond as 1:2 and 3 subtype - when makes the given parity 2:1.

Researches of group of skulls with presence of an intact occlusion in our work have shown, that the optimal variant for normal functioning VNCHS is the variant of the symmetric S-shaped form of an articulate surface of a temporal bone; the least favorable - the second subtype when the sizes of a mandibular fossa considerably exceed the sizes articulate bugorka. In this case the mandible head gets big freedom at movement that can provoke occurrence of dysfunction VNCHS, in particular, its dislocations.

According to the received results, the greatest diffusion to group of skulls with an intact occlusion was received by the S-shaped form articulate bugorka and a mandibular fossa (78,3 %), and in 49 % the first subtype (a parity a bugorok-pole 1:1), in 25,5 % - the third subtype (a parity bugorok - a fossa 2:1), in 3,8 % - the second subtype was observed. Frequency of occurrence of the flat form has made 21,7 %. In group full absence of a teeth most often there was a flat form of an articulate surface of a temporal bone (47,2 %).

For studying of influence of unilateral defects of dentitions on morfometricheskie indicators of articulate surfaces VNCHS us were estimated differences of indicators for each parametre with kontrlateralnyh the parties a method of the variance analysis (ANOVA). Presence of statistically significant differences on the parametres characterising the sizes of a head of a mandible at the left and on the right, explains that fact, that at partial absence of a teeth appreciable variability of the form of a head of a mandible on the right and at the left is observed, that is not characteristic for groups IP and POSES. It is established, that at partial absence of a teeth statistically significant differences are taped between relative differences of sizes on the majority of parametres. Therefore in some cases on jaws with partial defects of dentitions the form of a head of a mandible on the right and at the left is not identical.

It is necessary to notice, that at carrying out of a clinical part of research it has been taped, that as partial and full loss of a teeth, and also the raised erasability of a teeth have such okkljuzionno-caused diseases
The big prevalence at women. This circumstance, possibly, is one of the basic factors causing the big prevalence of dysfunction VNCHS in given group. Some authors notice, that the big frequency of dysfunction VNCHS at women is bound, first of all, to their higher "medical" activity (Ivasenko G. SH from co-workers., 2007). In our opinion, there is a number of the anatomic preconditions promoting more frequent development of diseases VNCHS at persons of a female. In the spent research it is shown, that for women depth of a mandibular fossa (less than 7 mm) and height articulate bugorka (less than 11 mm) is characteristic insignificant. Also neodinakova dynamics of changes of articulate surfaces VNCHS at loss of a teeth - at women in larger degree cross-section diameter of a head of a mandible and height articulate bugorka in comparison with men decrease.

Our research has shown, that at ordering of skulls on verhnelitsevomu to the index the expressed differences of the sizes of articulate surfaces VNCHS between lepto - meso-and euriprozopami are absent. However at the given forms of a facial skull features of topography of a kamenisto-drum-type cleft are established. At lepto - and mezoprozopov it is located on back edge of a mandibular fossa, and in group euriprozopov - in its medial third that can be in the latter case the additional contributing factor of development of syndrome Kostena.

For ordering of the studied skulls by kinds of an occlusion we used V.N.Trezubova's classification from co-workers. (2002). According to it, all kinds of occlusions share on two groups - normal either functional and abnormal or nonfunctional. The orthognathic occlusion is normal, to abnormal kinds of an occlusion carry: a distal occlusion, mezialnyj an occlusion, a deep occlusion, an open bite (or vertical dezokkljuzija) and a crossbite. Transitive kinds of a normal occlusion are separately surveyed: orthognathic with deep reztsovym overlapping, orthognathic with
retruziej forward teeth, a direct occlusion, orthognathic with a protrusion of a forward teeth.

In the work spent by us at studying of skulls with various kinds of an occlusion, it is established, that most often erasability of firm tissues of a teeth both on top, and on bottom jaws it becomes perceptible at a direct occlusion since only it is characterised by presence of 3 degrees of erasability. Erasability of firm tissues of incisors of the top jaw is more often observed at mezialnom an occlusion, mandible incisors - at deep. Both at men, and at women erasability of canines most often develops at a distal occlusion; the top premolar tooths - also at the distal form of an occlusion, the bottom premolar tooths - at its open form. The similar picture is observed and at molar tooths: the distal occlusion more often other forms of an abnormal occlusion causes erasability of firm tissues of molar tooths of the top jaw; opened - bottom. Thus, the occlusion pathology is one of contributing factors of development of the raised erasability of a teeth.

The question on influence of a kind of an occlusion on development of dysfunction VNCHS remains not up to the end solved. So T.V. Macfarlane et al. (2009) assert, that there is no direct pattern between anomalies of an occlusion and diseases VNCHS, and there is only mutual burdening of these two processes. In appreciable number of the works based on data of long-term observations, the role of anomalies of an occlusion in occurrence of dysfunctions VNCHS is denied. So A.J.Vjazmin (1999) mentions following facts: at patients the orthognathic occlusion meets obvious signs of dysfunction VNCHS in 57,3±1,33 % of cases; deep - 18,8±0,92 %; a straight line - in 6,5+0,17 %; progenichesky - in 5,0±0,16 %; from what that the orthognathic occlusion prevails at patients with this disease of a joint follows not only that dysfunction can be and at a normal occlusion, but also. J.A.Petrosov (2007) also found an orthognathic occlusion at 80 % of patients with dysfunction VNCHS.

In L.V.Muzurova's dissertational research (2006) notices, that patients in 80 % of cases have anomalies of dentitions and in 98 % a pathology of temporally-nizhnecheljustnogo joint. According to other researchers,
Distinct communication of pathology VNCHS with certain kinds of an occlusion (deep, distal, two-dimensional) (Semkin V. A, Rabuhina N.A., 2000 is traced; Horoshilkina F.J., 2006).

By us it is established, that at a distal occlusion in comparison with normal or transitive forms there are statistically authentic differences on the parametres characterising a mandibular fossa. For a deep occlusion in comparison with the orthognathic difference on two parametres is characteristic at once: sagittalnomu to diameter of a head of a mandible and depth of a mandibular fossa.

At mezialnom an occlusion of value of height articulate bugorka make 10,2±0,5 mm at men and 9,2±0,4 mm at women, and depths of a mandibular fossa 6,3±0,5 mm and 5,9±0,6 mm accordingly, that is authentic less (p
