Abstract
Aims and Objective: Prospective observational study was designed to assess clinical outcomes following total alloplastic temporomandibular joint replacement (TJR) in end stage temporomandibular joint (TMJ) disorders with study duration of 18 months. Primary objectives were to assess Maximum inter incisal opening (MIO) and Reduction in pain score. Secondary objective were to access Masticatory efficacy, Post-operative occlusion, Range of motion and Post-surgical Neurological deficit.
Material and Method: With inclusion and exclusion criterion total 11 patients kept in study. Data was collected and statistically analyzed using Statistical Package for Social Sciences (SPSS ver 21.0) [6].
Results: 12 month postoperatively mean MIO was 28.82 mm, with significant improvement in pain score, masticatory efficiency and stability of occlusion. For protrusive movement if bilateral TMJ replacement cases are excluded from data then there was no effect on the outcome. Data shows statistically significant improvement only after 12 months. With exclusion of bilateral cases test shows no significant improvement in contralateral laterotrusive movement.
Conclusion: Alloplastic TMJ TJR proved as an additional armamentarium for Maxillofacial Surgeons. However patients should be explained thoroughly regarding outcome achievable in protrusive and laterotrusive movements. MIO, pain score and masticatory efficiency improved a lot with TJR treatment.
