Abstract

This research introduces the manufacturing process of the metal-framework of one of the maxillary partial dentures, the "obturator", using milling wax-blocks, for patients with palate loss due to oral cancer. It explains the protocol of taking the patient's oral impression, preparation of a working cast, scanning, designing using a computer-aided design program, investing the milling wax-blocks, and completing the obturator. This method does not follow the traditional wax and agar process thereby reducing the errors arising during the manufacturing process and decreasing the time, material, and labor required. Moreover, the retention, stability, and compatibility of the metal framework were observed to be high in both the working cast and oral cavity.
