[Planning of orthodontic treatment in patients with maxillary dentition defects using mathematical methods]

Abstract

Stress-deformed status of bone tissue in the implantation zone was studied. The relationship between the level of strain in the spongy and cortical layers of the bone and spatial location of the implant in the jaw and its geometrical parameters is demonstrated. Numerical analysis of the level of bone tissue stress was carried out on the basis of experimentally created three-dimensional solid-body model of the maxilla. The process of changes in the distribution of tensions during different phases of mastication was investigated. The potentialities of numerical analysis in the planning of orthodontic treatment of patients with dentition defects making use of implants are demonstrated.
