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