Abstract :
Background: Surgical excision of the maxilla results in communication between the oral cavity, nasal cavity and maxillary sinus. Rehabilitation of such defects involves fabrication of obturator prosthesis by the maxillofacial prosthodontist. Various techniques and materials have been used in the past for rehabilitation of such defects.
Aim: To Fabricate a Obturator Prosthesis using Light Cure Wax Pattern.
Case Description: A 65-year-old man reported with the chief complaint of inability to chew food due to an ill-fitting prosthesis. His history revealed that patient had undergone maxillectomy of left side due to Carcinoma maxilla 03 years back, followed by the fabrication of a definitive obturator prosthesis. Intraoral examination revealed a well healed Aramany’s Class II post maxillectomy defect on the left side measuring 5 cm X 3.5 cm anteroposteriorly and mediolaterally, with everted margins and irregular borders. This clinical report describes rehabilitation of maxillectomy defect with definitive obturator prosthesis. A light cure wax pattern was used (LiWa®; Willmann & Pein Gmbh) for the fabrication of metal framework.
Conclusion: Fabrication of a cast metal framework involves a complex laboratory procedure to achieve the clinical success of the prosthesis. LiWa light curing waxes can be successfully used as an alternative to the conventional wax pattern for the fabrication of cast partial dentures framework for definitive obturators.
Clinical Significance: The light cure wax pattern helped in reducing the number of laboratory steps and allowed wax pattern trial in the patient's mouth, saving precious time and ensuring a precise fit of the prosthesis.
