A retrospective evaluation of 301 TMJ Proplast-Teflon implants

Oral Surg Oral Med Oral Pathol. 1990 Sep;70(3):381-6. doi: 10.1016/0030-4220(90)90164-n.


A retrospective review of 301 meniscectomies with Proplast-Teflon implants was performed. Factors such as interincisal opening, occlusion, joint sounds, joint degeneration, and patient satisfaction were examined. The overall surgical success rate was 88.7%, with an average follow-up period of 33 months. Although many patients demonstrated significant condylar degeneration at 1-year follow-up, such change did not necessarily result in symptomatology or joint dysfunction. Only 10% of implants resulted in removal. Surgical and postoperative procedures are contrasted with those of other clinicians experiencing lower success rates.
