An unstable lower complete denture is one of the most common problems faced by edentulous patients.  Rehabilitation of a patient with severely resorbed mandibular ridge is a challenge to the prosthodontist. The neutral zone is the area in the oral cavity where during function, the forces of the tongue pressing outward are neutralized by the forces of the cheeks and lips pressing inward. The technique of neutral zone is to construct a denture that is shaped by muscle function and is in harmony with the surrounding oral structures. This clinical report describes rehabilitation of a patient with severely resorbed mandibular ridge using neutral zone impression technique.
Key words: Neutral zone, resorbed mandibular ridge, denture stability
