The effect of temporary hydrostatic splint on occlusion with computerized occlusal analysis system.

Aims: The aim of this study was to evaluate the effect of temporary hydrostatic splint on occlusion with computerized occlusal analysis system. Material and Methods: Maximal bite force was recorded in intercuspal position by use of computerized occlusal analysis system from 11 female, 9 male, 20 subjects, (average age of 20) with normal intact dentitions. Subjects were instructed to use the hydrostatic splint for 24 h. Occlusal records were repeated three times before and after splint. All recordings were evaluated to determine the repeatability of the computerized occlusal analysis system. Results and Conclusion: Hydrostatic splint increased maximum biting force. Relative percentage of left and right bite forces changed in the direction of neurophysiological position of the muscles. Hydrostatic splint can be a viable option for occlusal adjustments.

The purpose of this investigation is to construct a device to measure occlusal stresses at a fixed point, to include in the design of a fixed restoration the concept of strength produced when occluding. Once this is done numerically the level of error can be decreased. The basic procedure used was the analysis of internal stressed produced on a tooth when occluding, through the study of photoelasticity in two-dimensions and the system of finite elements. In order to design the Strain Gauge several types of transducers were studied: a) Strain Gauge B) Pressure of Force Gauges c) Displacement Gauges.
