Abstract
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. (J Prosthet Dent 2000;83:652-5.)

After 8 years of successful maxillary denture-obturator wear, the patient presented with an ill-fitting obturator that was nonretentive and caused frictional lesions on the mucous membrane of the postsurgical defect (Fig. 1).

The manufacturers recommend brushing the prosthesis 3 times daily under running water with a toothbrush and normal or liquid soap (possibly neutral soap). Commercially available cleaning liquid may be used, but the denture should not be immersed for more than 10 to 15 minutes to avoid discoloration. However, the denture base may remain functional for longer than the resilient silicone obturator. In these situations, a clinical technique to replace the obturator without replacement of the denture base is useful. A simple technique is helpful in the management of a case that is not routine, that usually requires specialist treatment, and in which the patient has already undergone extensive surgical treatment.<ce:cross-ref refid="bib15"><ce:sup>15</ce:sup></ce:cross-ref></ce:para></ce:section><ce:section><ce:section-title>Summary</ce:section-title><ce:para>This article describes a simple technique to replace a silicone bulb obturator, and a patient treatment was used to illustrate the procedure.

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.
