Fabrication of Complete Dentures Using the Neutral Zone Technique in a Patient with Severely Resorbed Mandibular Ridge

Abstract

Background Edentulous patients with severe mandibular ridge resorption often experience poor denture stability and retention. The neutral zone technique, which positions teeth and contours polished surfaces in harmony with the functional forces of the tongue, cheeks, and lips, has been shown to improve patient-reported outcomes compared with conventional methods.

Objective To present the fabrication of complete dentures using the neutral zone technique for a patient with severe mandibular ridge resorption, demonstrating a feasible approach in a community hospital setting.

Methods The maxillary denture was fabricated following conventional procedures. For the mandibular arch, the neutral zone was recorded using an admixed compound, and a silicone index was used to transfer the functional form. Monoplane occlusion was adopted, with slight cross-overlap of the anterior and posterior teeth to accommodate tongue space. The polished surfaces were sculpted according to functional movements.

Results The denture exhibited satisfactory retention and stability. The patient reported comfort during mastication and clear speech. Minor sore spots noted at the 3-day follow-up were successfully adjusted. At 1-, 3-, and 6-month recalls, no recurrent pressure lesions were observed.

Conclusion The neutral zone technique is a simple and effective option for patients with severe mandibular ridge resorption when implant treatment is not feasible. It enhances denture stability and patient satisfaction in community clinical practice.
