Assessment of occlusion with the T-Scan system in patients undergoing orthognathic surgery

Abstract Dental occlusion varies among individuals, and achieving correct physiological occlusion after osteotomy is essential for the complex functioning of the stomatognathic system. The T-Scan system records the centre of force, first contact, maximum bite force, and maximum intercuspation. The a...
