[Electrognathography and its application in dentistry].

Abstract

The problem of spatial recording and analysing of mandibular movements was always of interest in dentistry. The permanent development of new technologies has resulted in a wide range of various methods and measuring systems for recording mandibular movements. However, only some of them have fulfilled a greater number of evaluation demands of modern measuring systems, which permit their industrial production. The paper discusses electrognathography as one of the most up-to-date methods widely used in the study of mandibular kinetics. The principles, performance and various possibilities of use of the two commercial electrognathographic apparatuses, now present on the world market, are presented. They are Sirognathograph (Siemens A.G., Bensheim, W. Germany) and Mandibular Kinesiograph (Myo-tronics Research, Seattle, U.S.A.)
