A Clinical Evaluation of Implant-Supported Maxillary Obturator Prostheses: An Original Study

INTRODUCTION: Rehabilitation after the maxillectomy is challenging to the clinician and the patient. Since the invention of the implants, the rehabilitation has changed the treatment strategies. Hence in our study, we evaluated the maxillary obturator that is implant supported. MATERIALS AND METHODS: We piloted a retrospective analysis of the patients who received the maxillary obturator prosthesis with implant support from the department records from 2010 to 2020. We finalized 50 subjects who fit the criteria and evaluated clinically for various parameters. The comparison of these parameters was done using the Chi-square tests deliberating P < 0.05 as significant. RESULTS: We observed that the implant survival was 94%. There was significant variation for the implant bone height (P = 0.001) and the implant threads exposed (P = 0.044) for the posterior and the anterior regions. CONCLUSION: The implant-supported maxillary obturator prosthesis has been shown to perform clinically satisfactorily. The success of the implant-supported maxillary obturator is dependent on the time of the placement, load applied, the radiation regime, and the patient follow-up.
