AN INNOVATIVE TECHNIQUE FOR ACRYLISATION TO FABRICATE HOLLOW BULB OBTURATOR USING CHLORINATED POLYVINYL CHLORIDE (CPVC) PIPE

The goal of prosthodontics is the rehabilitation of missing oral and extra-oral structures with the restoration of normal function of chewing, speech, swallowing, appearance, etc. Malignancies are common in the oral region and are treated through surgical intervention. Surgical intervention creates anatomic defect which forms communication among the oral cavity, nasal cavity, and maxillary sinus. In such cases, it is very difficult for the patient to perform various normal functions like mastication, swallowing, speaking, etc. Prosthodontic rehabilitation with an obturator prosthesis restores the missing structures and acts as a barrier between the communications among the various cavities. The main problem with the rehabilitation of defects difficulty involving in the processing of bulky prosthesis. Different techniques have been described in the literature using cardboard boxes,custom-made flasks or no flask at all which are having their own drawbacks affecting the dimensional stability of the prosthesis. This case report describes a simplified, inexpensive and easy method of processing an obturator for the rehabilitation of a maxillary defect using chlorinated polyvinyl chloride (CPVC) pipes.
