CONDYLAR CHANGE AFTER UPWARD AND FORWARD ROTATION OF THE MAXILLOMANDIBULAR COMPLEX

Tomographic radiographs of 44 healthy temporomandibular joints in 22 p atients undergoing large upward and forward rotations of the maxilloma ndibular complex were evaluated, Immediate postsurgery results showed decreases in all areas of the joint space. Long-term results showed a decrease in the superior and posterior regions, 14.8% and 19.7%, with no significant change anteriorly. Simple and multiple regression analy sis did not show any relationship with age, gender, or degree of chang e in the decrease of the occlusal plane angle, to the temporomandibula r joint changes described. Some condylar remodeling was noted.
