Prosthetic Rehabilitation Of A Maxillary Defect With Hollow Bulb Obturator Retained By A Combination Of A Cast Clasp And Zest Anchor Type Radicular Ball Attachment- A Case Report

摘要

Prosthetic rehabilitation of patients with acquired defects of the maxilla present a challenging task and these goals are met by means of an obturator prosthesis. Palatal defects that are treated prosthodontically, present biomechanical problems. An obturator prosthesis fabricated for a unilateral maxillary resection, has intrinsic leverages that act as dislodging factors. Many methods have been recommended to accomplish the retention of maxillary obturator prostheses. The placement of radicular attachments and the process of making the prosthesis hollow can have a significant effect on the stability and retention of the obturator prosthesis in partially edentulous maxillectomy patients. This case report describes a clinical case of sub-total maxillectomy due to osteomyelitis, which was successfully rehabilitated with a hollow bulb obturator, retained in a unique combination of a cast clasp and zest anchor type of radicular ball attachment.
