Altered Cast Impression Technique: A Case Report

Abstract

Distal extension removable partial denture is one of the treatment of choices to replace missing teeth in Kennedy Class I and II partial edentulous patient. These dentures only have partial support from teeth as their bases may be extensions covering the ridge distal to the last abutment tooth. However, a mismatch between tissue resiliency at the distal extension base and teeth causes a rotational movement of the dentures, resulting in tooth damage, soft tissue ulceration and a residual ridge resorption. This case report describes patient who had difficulty to masticate the food. He would like to have dental prosthesis. Intra-oral examination shows partial edentulous arch in maxilla and mandible. Occlusal plane discrepancy. He received a maxillary removable partial denture, mandibular distal extension removable partial denture with altered cast impression technique to improve aesthetic and masticatory function, after treatment, patient is satisfied with aesthetic, pronunciation and mastication.
