Interferometry in the assessment of biomechanical features of the masticatory system hard segments

Biomechanical studies have found wide application and solved many problems in dental medicine. An interdisciplinary approach has allowed an ever-faste r progress in the field. The aim of this study was to point out the advanta ges of holographic interferometry. With the use of this method the study ob ject is observed as a whole rather than as a substrate, thus providing a th ree-dimensional holographic image visualizing the load transmission from on e jaw to another, tooth pressure against the alveolus, and strain of Sharpe y's fibers, and yielding precise data on deformities, dislocations and forc e distribution.
