Treatment of temporomandibular joint ankylosis with methyl methacrylate interpositional arthroplasty: reprot of four cases.
Four cases of interpositional TMJ anthroplasty are presented. All patients had been operated on previously. The initial success was compromised by reunion of the proximal and distal surgical sites. These failures were due to inadequate gap arthroplasty; lack of complete coverage of the superior distal stump; or lack of retention of the alloplast at the site of placement. The case of manipulation and good tissue tolerance of methyl methracrylate make it an excellent material for interpositional arthroplasty.
