Summary: Contemporary diagnostics of the stomatognathic system's function require various diagnostic, therapeutic as well as control procedures, which unavoidably connect the science of dentistry with different interdisciplinary branches, i.e. biomedical instrumentation as well as computer analysis of biosignals. This project is therefore basically aimed at obtaining qualitative and quantitative data from the field of kinetics of healthy individuals as well as pathologically altered stomatognathic systems by the use of non-invasive and repeatable methods, such as the method of surface electromyography (EMG) of masticatory muscles, investigation of the latency and duration of the silent period, test of isometric load response, registration of occlusal sound by the gnathosonic method and real-time analysis in reference to EMG recordings. These recordings are obtained on a specially designed PC-based system for the registration and analysis of electromyographic signals and sounds from occlusal contacts. Six channels are used for the registrations of EMG signals and two channels are for sound registrations. This system was created as the result of a long- term experimental study and collaboration between the School of Dentistry and Faculty of Electrical Engineering in Zagreb of the University of Zagreb, and further experimental work is directed towards new possibilities of the systems upgrade, such as new possibilities for the measuring of bite-force according to masticatory units or segments. The early experimental phase of the PROJECT deals with the measurements and assignments of anthropometrical marks and esthetic components by the use of 3-D image analysis and computer or video- processing, mostly due to the deficiency of necessary equipment. This section is therefore mostly theoretically elaborated and prepared for future realization.

Keywords: Gnatho-kinetic, electromyography (EMG), masticatory muscles, silent period, gnathosonics, gnathodinamometrics, diagnostic of disfunction, early reveal of disfunctions, PC-analysis of the registrations, 3-D analysis of the face, computer dental graphics

Research goals: The necessity for the use of the different diagnostic as well as therapeutic and control check-up procedures inevitable connects the science of dentistry with the other interdisciplinary areas, as certain knowledge or the results obtained in experimental work from other scientific branches could find their usage here. The aim of this project is to upgrade available methods by relating the problems in the field of dentistry with methods from other scientific fields such as biomedical electronics, computer analysis of biosignals and medical informatics concerning the fields of analysis preparation and results evaluation. The investigation is designed as three main topics that are going to be simultaneously realized: * Section I deals with the examination of the stomatognathic system's normal activity in subjects with natural teeth and in complete or partial denture wearers, through methods of quantitative kinesyological investigations. * Section II is composed of the examination of dysfunctional symptoms, as well as TMJ and myofacial pain syndrome comprising the examination through various therapeutic procedures. * Section III is directed to the investigation of the anthropometrical and cephalometrical parameters by using photographic and video-records and their digitalization and processing by a computer system and other necessary peripheral equipment.
