ABSTRACT :
In 1990 , the FDA advised oral and maxillofacial surgeons against the use of proplast-coated TMJ implants . It , further , requested that all unused implants be returned to the company . This was followed , in 1991 , by the advisory with the directive that patients with proplast-coated implants should be annually evaluated clinically and radiographically . If there is evidence of progressive implant changes , the implants should be removed . Hence , this clinical study presented the management of failure of some alloplastic TMJ implants . Thirteen patients with failed proplast-coated disc implants were collected . The alloplastic implants were removed , and a temporalis muscle flap was rotated and inserted instead . Patients were observed for a period of 6-12 months . It was found that placement of temporalis muscle and fascia flap is effective in the management of failed implants .
