Complete Denture for a Severely Resorbed Ridge: A Case Report

Abstract

A complete denture is a prosthesis commonly used to replace missing dentition and associated structures in the oral cavity. The success of a complete denture depends on several factors, among which the condition of the underlying denture-bearing area plays a significant role. Residual ridge resorption is a complex biophysical process and a common occurrence following tooth extraction. The rate of residual ridge resorption varies between individuals and even across different times and sites within the same person. Ridge resorption presents a clinical challenge in the fabrication of a successful prosthesis. This case report discusses a
72-year-old Thai male who presented with complaints of a loose upper single denture and lower partial denture and sought a new denture. Prosthesis management for the severely resorbed mandibular ridge involved the functional impression technique. The neutral zone technique was employed to achieve optimal stability for the mandibular denture. For the maxilla with flabby tissues, the selective impression technique was used with a custom tray incorporating a window over the affected areas. Post-treatment results showed that the patient was satisfied with the esthetics, stability, retention, and masticatory efficiency of the complete denture.
