Abstract

A new method for precision measurement concerning the dynamics of human teeth in function was applied to different clinical situations in a series of experiments. Intraalveolar tooth mobility was recorded utilizing a ruby laser system for double pulsed holographic interferometry.

The masticatory force of the patients caused various interference fringe patterns in the holograms. Their evaluation revealed different types of tooth mobility corresponding to the nature of force application.
