The Artex Adjustable Platform can be set to varying occlusal plane positions with our handy thumb wheel adjustment (+5mm to -5mm). When used in conjunction with our Index Trays, the Adjustable Platform assists in mounting the upper cast to the articulator. AD2?s unique dual lock pin construction ensures that the platform top remains strong and stable over the life of the Adjustable Platform (no more anterior-posterior rocking).? This platform is designed for the newer Artex Carbon Fiber articulator series (interior vertical height = 126 mm).
