Neutral zone approach to denture fabrication for a severe mandibular ridge resorption patient: Systematic review and modern technique

Abstract

Conventional complete denture therapy for patients with severe residual ridge resorption is challenging. The dental implant therapy may be a treatment option for improving the denture support, retention, and stability. However, the neutral zone technique is also considered to be an important alternative approach to patients complaining of unstable dentures, particularly when implant therapy is not feasible. This technique is by no means new, but is not widely practiced due to lack of experience of dentists. The aim of this article is to describe historical perspectives on the neutral zone concept. In addition, a modified modern neutral zone technique is presented to reconstruct a lower complete denture for a patient with severe ridge resorption. The new definitive complete denture successfully improves stability, comfort, and function for the patient with severe mandibular ridge resorption.
