The relevance of research. Biomechanics of the dentition, its problems and solutions are one of the main problems of modern dentistry Various aspects of this issue, such as load force, emerging stresses both in the abutment teeth and in the places of the defect, depending on the magnitude of the atrophy of the collar spine, the stability of the occlusion, compensatory-adaptive function of the periodontium, etc., a lot of research has been devoted. Purpose of the study: creation of a mathematical model of the dependence of the load arising in the area of the tooth, and orthopedic wild design, depending on the magnitude of atrophy of the cellular shoot of the lower jaw. Materials and methods. For the study, the mathematical aspects of the approach to determining the stresses in depending on the amount of atrophy of the bone tissue of the cellular shoot of the lower jaw. Results and discussion. Such mathematical models will allow clinicians to quickly diagnose clinicalsituation and draw the necessary conclusions about the choice of treatment method. A universal mathematical model allows you to exploredependence of the tension in any tooth that occurs during chewing load, and the magnitude of atrophy, depending on wear of the bone tissue of the cellular shoot of the lower jaw. Conclusions. A mathematical model of the effect of stresses in the tooth from the magnitude of bone tissue atrophy has been developed. First a formula is obtained that connects the stresses arising in the tooth with the magnitude of atrophy of the bone tissue. First received the formula for determining the maximum stresses depending on the atrophy of the bone tissue. Tensions at the base of the tooth depending on the magnitude of atrophy (σmax and σmin stress are shown). Given mathematically the model makes it possible to predict the forthcoming destruction of the tooth from the magnitude of bone atrophy. Key words: mathematical modeling, collar growth atrophy, tension, defect.
