Replacement of an obturator section of an existing two-piece implant-retained edentulous obturator.

There is an increasing number of people in the community who have postablative surgery for tumors of the maxilla. Postsurgical defects these individuals have are usually restored by means of a complete or partial denture obturator with various materials, including resilient silicone extensions. These patients require long-term maintenance of their obturator prostheses, which must be considered in the context of their general health and ongoing medical care. When a resilient silicone bulb is used to obturate the defect, the silicone sometimes deteriorates, whereas the denture base remains functional. This article describes a simple procedure to construct a replacement, resilient silicone bulb obturator while retaining the original complete or partial denture base.
