[Basic investigation using K6 diagnostic system. 3. Fabrication of the apparatus wearing a Sensor Alley and the evaluation of its accuracy].

Unlabelled: An investigation was undertaken to evaluated the accuracy of Sensor Alley, a mandibular movement analyser: K6 Diagnostic System EX with a newly designed auxiliary apparatus.

Results: 1) The errors in the values of the standard Sensor Alley were 4.8 mm for the VER-coordinate, 5.0 mm for the AP-coordinate and 3.0 mm for LA-coordinate. 2) The errors of the AP-coordinate were bigger than those of the VER and LA-coordinates. 3) The errors in the values of the standard Sensor Alley fitted with a newly designed auxiliary apparatus were 0.9 mm for the VER-coordinate, 2.0 mm for the AP-coordinate and 1.1 mm for the LA-coordinate. 4) The results led to the conclusion that this newly designed auxiliary apparatus was useful for various studies on mandibular movement used with the K6 Diagnostic System EX.
