Abstract : The present report is primarily concerned with initial observations regarding force generation and internal stress analysis obtained with a revolutionary device. The introduction of a method by which intraoral forces could be measured and traced over the occlusal surfaces of teeth was investigated. Two systems were necessary to gather the necessary data, the first was a force transducer, and the second was an occlusal topography recording device. The transducer has the ability to record measurements at the rate of 150 every one-tenth of a second, this information is stored on magnetic tapes in analog form and is then converted to digital information for computer analysis and plotting. This data is returned in two or three dimensional configurations with forces computed and positioned over the three dimensional portrayal of the original occlusal surface. It is possible to calibrate the axial center of such a tooth and to evaluate the effects of various occlusal relationships. Since much of the injury to the periodontium and the neuromuscular apparatus supposedly related to premature contacts and resultant bruxing, information regarding the behavioral characteristics of bruxers and non-bruxers over extended periods of time will be extremely meaningful. Therefore, we are now also involved in telemetric evaluation of tooth contact patterns over longer periods of time using portable receiving and recording devices. (Author)
