Abstract
This paper presents an experimental application of the fringe projection method for evaluating the pre-molar teeth deformations, under different load conditions. It was developed an algorithm for digital images reconstruction, which is able to process and evaluate the teeth deformation behavior. The teeth samples were placed in polystyrene resin and fixed in a support with a rod, for load application. The different workloads were 25N, 50N, 75N and 100N, applied in the long axis of the teeth. The levels of displacements were as low as 1.4 × 10−3mm, for applied load of 25 N and 1.85 × 10−3mm for 100 N, giving a displacement-load slope of approximately of 6 nm/N.
