Study of mandibular kinetics by COSIG. Computerized sirognathograph system.
Several programs for coupling Sirognathograph to personal computer are available on the market (Maruyama's SGG Analyzing System Radke's Bio-Pac-Software, Fabris's Computersystem for Sirognathograph S) or are in various non commercial versions used in research (Lewin, Micheler, Proeschel). The COSIG System consists of the software and the hardware (Sirognathograph S--Siemens, XY 575 Recorder Esterline Angus, Personal computer IBM XT, IBM Graphics, Printer, A/D converter Tecmar Labmaster, Roland Plotter 880 DXY). The COSIG software records simultaneously X, Y, Z data from SGG, store and retrieve them. Mandibular movements are presented in time plot mode, in the three planes, in speed and acceleration plots, using different magnifications, direction color code, deliberate observation times, enables zero adjustments and storing of particular situation with comments on it within the file. Simultaneously graphic presentation goes by XY recorder, while stored data are screen printed by Graphic printer or color and black and white plotted by XY plotter. Standard patient examination using COSIG comprises three files i.e. border movement potential, contact movements and chewing standard bolus has been proposed.
