Mechanical Analysis of Reconstruction Plate for Segmental Resection Case

—The Influence of the Segmental Resection Position—

Abstract

The purpose of this study was to investigate segmental resection of the mandibular bone by using the 3D finite element method. A 3D finite element model with mandibular bone resection was constructed. Mandibular reconstruction plates were inserted at the lower border of the mandibular bone and secured by screws.
The analysis items were as follows: equivalent stress distribution of mandibular reconstruction plates, equivalent stress distribution of screws and equivalent stress value of screws.
As a result, it was suggested that the size of defects of the jaw affected the mechanical effects of the plates and screws.
