Rehabilitation of Patient with Acquired Maxillary Defect Using Cast Partial Obturator with Precision Extra Coronal Attachment

Abstract

The prosthetic rehabilitation of a patient with maxillary defect is a very challenging task. Obtaining proper retention when almost half the dentition along with the supporting bone is missing is difficult to obtain. Proper knowledge of the anatomy of both the structures lost in resection as well as the remaining portion helps in fabrication of an effective prosthesis. This article describes the management of acquired maxillary defect case with semi precision attachments enhancing the retention of the obturator prosthesis. Keywords: precision attachments, definitive obturator.
