Abstract:

Loose and unstable lower complete denture is a common problem faced by edentulous patients with severely resorbed mandibular ridges. Neutral zone technology serves as a guide of where to set teeth and how to contour the polished surface of the denture to ensure optimal stability, retention, facial support, and esthetics with complete denture, and patients are satisfied with the technology. This technique is not new but is not widely practiced due to lack of experience of dentists. This review summarizes the characteristics and importance of neutral zone technology, the materials and techniques for recording the neutral zone, and some related topics. This research will aid in the clinical application of neutral zone technique.

Key words: neutral zone, edentulous jaw, complete denture
