| Research Abstract |
The 3-D load-measuring device, comprised of a piezo-electric force transducer and the experimental superstructure, was developed. The devices were tightened with screws into implant-fixtures in the subjects. The 3-D loads during the maximum voluntary cenching (MVC)and biting a piece of paraffin wax (WAX)were registered. The magnitude and direction of the recorded loads were analyzed in the spatial coordinates based on her Frankfort and sagittal planes. The device enabled us to estimate the 3-D loads on t he implants. Load exerted on the implant supporting fixed superstructure during chewing function was larger than that during clenching. The amount of change in the load direction during chewing was larger than that during chewing. It was suggested that the species of teeth or occulusal contact was affect the load direction
