COMPARATIVE STUDY ON DIFFERENT DENTAL IMPRESSION TECHNIQUES USED IN PARTIAL EDENTOULISM

Abstract

Aim of the study This paper aims to evaluate different impression techniques used in making fixed prosthetic devices in terms of patient comfort, ease of registration and not least the fidelity of these techniques. Material and methods Records of prepared teeth were made by global trays and silicone materials and different techniques have been developed. Results The main disadvantage of the impression technique is that it is timesensitive, and also requires coordination between the dentist and the dental assistant. Conclusions The most convenient and reliable way of recording a putty-wash impression is to use the one stage technique with addition silicone putty in a metal tray
