ABSTRACT

We report a surgical technique for habitual temporomandibular joint dislocation. Cortical bone was shaved at the anterior slope of the tubercle, and a piece of an autogenous bone block was grafted to augment the tubercle. The grafted bone was fixed with a titanium plate and screws. This method preserved the original posterior slope of the tubercle, permitting smooth condylar movement. We used this technique in two patients and followed them for 15 and 5 years, respectively. Postoperative examinations showed no resorption of the grafted bone and no recurrence of dislocation in either patient. Key words: habitual temporomandibular joint dislocation, surgical treatment, titanium mini-plate, bone graft.
