Parametric model of the structure of the second molar of a human lower jaw

Abstract

In this paper the design of a parametric tooth model is considered, with the help of which it is possible to study the development of dental pathology. This model allows you to create a tooth prosthesis, with minimal intervention of the dentist, by creating a three-dimensional image of the studied tooth, close in architecture to the real one. Particular attention is paid to the study of the geometry of the tooth - the second molar. Based on the analysis of the presented initial data, additional characteristics were introduced, due to which the geometry of the surface areas of the tooth model is calculated. The article discusses the advantages and disadvantages of visualization methods used in this area to solve problems associated with the analysis of complex and heterogeneous information, and also presents conclusions on practical and scientific results. A parametric model of a tooth was built, which describes its geometry in comparative detail. The main necessary parameters and their limitations are determined. The obtained calculations of the geometric shape of the tooth can be used to study and analyze the biomechanics of teeth, the principles of differential diagnosis of pain, planning future iatrogenic intervention, as well as algorithms for the treatment of prosthetic disorders, provides the doctor with all the necessary tools. The constructed crown part of the tooth in the AutoCAD system can be used for teaching dental students. This model can be used for scientific and practical activities of students on the modeling and restoration of dental crowns.
