A Fast and Economical Photoelastic Model Making of the Teeth and Surrounding Structure

Abstract

Photoelastic stress analysis is an experimental technique for stress and strain analysis. It is based on the property of birefringence. Simulation of the accurate geometrical shape and mechanical property of the material to be studied is a mandatory requirement. It has always been a donting task to make an accurate photoelastic model of the dental structure. Innumerable materials and indefinite methods are explained in the literature. This article provides with a simple, cost effective, easily available material and a simple technique for making a photoelastic model.
