Novel registration technique to register neutral zone

The three dimensional volume of complete dentures optimally occupies an edentulous space that is substantial, in the light of the progressive changes that accompany edentulism and functional dynamics. The paper discusses current knowledge of neutral zone registration and presents a novel technique for this registration.

Fabricate maxillary and mandibular occlusal rims over conventional record bases using high fusing impression compound. Register the maxillary and mandibular neutral zone separately by swallowing method and after try in of complete denture; remove the wax apical to the tooth surfaces and recording will be completed with putty and light body impression material.

Complete dentures are a biomechanical device that must be designed in harmony with normal neuromuscular function to get stability and proper function. Improper teeth positioning and polished surface contour will result in compromised stability of denture.

This article describes a preview of facio-lingual positioning of denture teeth along with a novel approach of recording the neutral zone with an elastomeric impression material.
