Abstract

We researched the point on kinematic axis which had a minimal range of motion in lateral excursive movements. We called that lateral condylar reference point (LCR point).<BR>We studied the range of motion, the relative position to the arbitrary point and to the morphological center of the condyle of the following 4 points: kinematic axis point, hinge axis point, cross point and LCR point.<BR>1. The range of motion of the LCR point was 0.47mm (anteroposterior), 0.79mm (lateral), 0.74mm (vertical) and 0.90mm (3-D).<BR>It was the smallest among the 4 points.<BR>2. The LCR point was located 1.31mm medial to the morphological center of the condyle.<BR>3. The LCR point was located 3.62mm anteriorly, 24.18mm medially and 4.57mm superiorly to the arbitrary point. Therefore, the LCR point is a suitable analysing point on the condyle in lateral mandibular movements.
