Stress Analysis of Mandibular Angle Region Concerning the Extraction of Impacted Mandibular Third Molar

Measurement of Strain Under Application of Bone Chisel-

Abstract

Experimental studies using airdried human mandibule were performed to define the mechanism of the development of fractures of the mandibular angle region.
It can be concluded that, by removal of bone during the extraction of an impacted third molar, it is important to try not to expose the tooth crown or to preserve the external oblique region for the prevention of a mandibular fracture. If these things have been done, the subsequent procedure, that is, the application of elevator, must be done very carefully. Furthermore, in the case of the application of bone chisel in the direction of the lower mandibular border, this procedure needs to be performed carefully to avoid fracturing of the mandibular angle region, because the amount of bone to be removed is large in such a case.
