Improving denture stability in a severely resorbed mandibular ridge using the neutral zone technique

The objective of prosthodontic treatment is to restore normal function, contour, esthetics, speech, and health. Optimal denture stability of conventional complete dentures is difficult to achieve especially in the mandible relative to that in the maxilla because of the less denture-bearing area and in patients with atrophic alveolar ridges. Many patients with atrophic mandibular ridges are elderly and have compromised health. Dentists need to have expertise in modern treatment options for managing cases with the atrophic mandibular ridge. We report a case that illustrates management of an atrophic mandibular ridge by modifying conventional techniques without the need for surgery. A 54-year-old male patient wanted complete dentures to improve his mastication and esthetics. The neutral zone impression technique was used on the mandible to obtain better stabilization. Polyvinylsiloxane light body impression material was used because the viscosity is easy to control and manipulate. The patient performed functional movements, including swallowing, sucking, and blowing, while the impression was made to obtain a neutral zone space.
