Abstract

The purpose of this study was to investigate the accuracy of working casts made from two types of model, aparallel type and an angled type. Athree-dimensional measuring microscope was used to measure reference points on the master model and working casts.<BR>The master model was made from metal, and standard points A, B and C were located on the base of the master model. Reference points were provided on the occlusal surface and on the measuring jigs for implants.Impressions were taken using a custom tray and additional type silicone impression material, and working casts were made. Then the working casts were measured and compared to the master model.<BR>The results were as follows:<BR>1. In the implant area the distance between the two implants was greater than that of the master model for both types of working casts.<BR>2. Clockwise rotation of the implants was observed in both types of working casts.<BR>3. For the angled type working casts, reference points of the remaining teeth moved to a lower position.
