Silicone molar block used as a fulcrum in condylar surgery.

Abstract

The narrowness of the temporomandibular joint (TMJ) can cause difficulty in open reduction and fixation of condylar fracture. The authors designed a silicone block that acts as a fulcrum to create more space around the TMJ. The block is made of high-quality silicone that is firm, elastic, nontoxic, autoclave tolerant, and harmless to dental tissue. This block has been used successfully in facilitating reduction and fixation of condylar fractures in 27 patients, and for releasing spastic muscles during closed reduction in 2 patients with prolonged TMJ dislocation. In edentulous patients, the silicone molar block can be used as a mouth opener to facilitate most intraoral procedures without injury to the gum.
