Rehabilitation of Severely Atrophic Mandibular Ridge using the Neutral Zone Technique

Oral functions such as speaking, chewing, swallowing, smiling, and laughing, require a complex combination of the tongue, lips, cheeks, and floor of the mouth. To ensure that these functions work properly, dentures must be designed to complement the natural neuromuscular processes of the mouth. In cases of highly atrophic ridges, the neutral zone technique is an alternative method for creating lower complete dentures. The goal of this technique is to construct a denture that is shaped by muscle function and is in harmony with the surrounding oral structures. This case report outlines a version of the traditional neutral zone technique that utilizes condensation silicone. The technique was used to treat a patient with an atrophic mandibular ridge who was experiencing issues with unstable old dentures.
