Use of Base Metal/Alloy Denture Base In Parafunctional Oral Habit – Case Report

Fracture of the conventional acrylic denture is one of the most common complaints of the patient. This is more evident in patients with heavy masticatory loads and those with parafunctional habits. This calls for the need for better material with good mechanical properties capable of withstanding all the functional loads effectively without fracture. A metal-based denture base due to its superior mechanical properties in this respect is a good alternative to acrylic dentures. This article discusses a case report of successful oral rehabilitation of a completely edentulous maxillary and mandibular arch in a patient with the heavy occlusal stresses. The patient had a habit of bruxism and clenching due to which he had fractured two complete dentures before. The cast metal base was fabricated first and then tried in the mouth following which other clinical procedures were performed. The patient after 1 year of follow up claimed to be extremely satisfied with the outcome of the prosthodontic treatment
