The investigation object: anatomical variability of a mandible for construction of computer model The investigation goal: the dissertation is devoted to specification of typical attributes of individual anatomical variability of a mandible for construction of computer model, modeling of changes of an alveolar arch at loss of dens and process of a virtual prosthetic repair by an implantation of artificial dens. Methods of research: preparation and morphometry, injections of vessels, hystologic, experimental and statistic ones. The theoretical and practical importance of the received results: Fixed, that basic anatomical and морфометрические of the characteristic of a mandible of the man depend on the form of a skull, sex and presence or absence of dens. The constructed computer model of a mandible on the parameters was analogue of the osteal prototype, that has allowed to simulate change of an alveolar arch in a place removed one or several dens, and also process of an implantation of artificial dens.The scientific novelty of the investigation results Fixed, that anatomical and морфометрические of the characteristic of a mandible are in direct dependence on the form of a skull, sex, presence or absence of dens. The forms of a mandible - брахи-, мезо- and долихоморфная are determined which have the expressed individualization of the basic parameters of a mandible: lengths of longitudinal and transversal diameters, height of a branch and processes (alveolar and суставного), configuration of the establishment and depth of a body, angle of an inclination and distance up to tooth sockets of the canal of a mandible, size of an angle of a mandible. In a mandible after an odontectomy (dens) there is a change of a configuration of an alveolar arch with резорбцией of an osteal tissue in a place of the removed dens. Thus the interrelations of the basic parameters of a mandible variate: the angle is enlarged, height decreases and length of a body of the mandible is enlarged. For computer modeling of a mandible in threegaugings on an outside surface of a mandible were determined плоскостные of coordinate of points, which quantitative parameters are a basis of computer modeling. The main disadvantage at computer modeling of an outside surface of a mandible with the help плоскостных of coordinates of points is their attachment behavior to a primary plane of construction. Correction of perimeter with introduction of parameters of depth of a body, branch of a mandible and its(her) processes therefore is necessary. The constructed computer model of a mandible of the man with the help of the computer program 3Ds Max8 on the dimensions, form, configuration of outside and intrinsic surfaces, completely coincides with the osteal analogue. At modeling an odontectomy (dens) it is possible to simulate on an alveolar arch process резорбции of a bone in a place of the removed dens and change of an angle of an axial load next to the removed dens. Developed on computer model of a mandible the process of a virtual implantation of artificialdens on морфометрическим and technical characteristics can be applied in a practical odontology as a preparatory stage of a prosthetic repair.The degree of implementation: medicine, human anatomy.
