Abstract

CONDYLOCOMP LR 3 is mandibular movement measuring device characterized by six degrees of freedom and a light reflective mechanism. The measurement accuracy of this device was evaluated.<BR>The results were as follows:<BR>1. The sagittal plane was expanded 4.8% in the sagittal and 5.6% in the vertical directions, by moving the reflector anteroinferiorly (the measuring point was 2.5 mm anterior and 2.5 mm inferior to the coordinate point). Further, the measuring point was 5.0 mm anterior and 5.0 mm inferior to the coordinate point, and expansion was 3.6% in the sagittal and 4.0% in the vertical directions.<BR>2. The sagittal plane was expanded 7.2% in the sagittal and 3.2% in the vertical directions, by moving the reflector internally 2.5 mm and anteroinferiorly (the measuring point was 2.5 mm anterior and 2.5 mm inferior to the coordinate point). Further, the measuring point was 5.0 mm anterior and 5.0 mm inferior to the coordinate point, and expansion was 7.4% in the sagittal and 4.3% in the vertical directions.<BR>3. The horizontal plane was expanded 7.2% in the sagittal and reduced 9.2% in the horizontal directions, by moving the reflector internally 2.5 mm and anteroinferiorly (the measuring point was 2.5 mm anterior and 2.5 mm internally to the coordinate point). Further, the measuring point was 5.0 mm anterior and 5.0 mm internally to the coordinate point, and expansion was 10.2% in the sagittal and reduced 3.2% in the horizontal directions.
