INTRAORAL SCANNING IN CR DETERMINATION.A DENTAL TECHNIQUE

Abstract

Aim of the study .This article describes a combined technique for digitally recording centric relation using an intraoral scanner and the Huffman Leaf Gauge device. Material and methods.Digital impressions were made for both mandible and maxilla using an intraoral scanner. Then a leaf gauge was used to deprogram the patient to the first contact of teeth and to ensure 1 mm of occlusal clearance between the posterior teeth. The interarch relationships were recorded on both sides with the mandible placed in CR at the determined OVD. Based on the previously recorded positions, using a model editing software and a 3D printer, the upper and lower models were printed, keeping the OVD determined with the leaf gauge.
