Impression Techniques in Implant

Implant impression is one of the most important steps in achieving passive fit by accurately relating an analogue of the implant or implant abutment to the other structures in the dental arch. Further the accuracy of impression is affected by the selection of impression tray, impression technique and type of impression material, number and angulation of implants. A variety of impression techniques for the fabrication of implant supported prosthesis have evolved in the past decade. Selection of a specific technique depends on the evaluation of a particular patient and the clinical situation present.This dissertation highlights the various techniques of impression making, their merits and demerits in the fabrication of implant supported prosthesis and also the selection of an appropriate technique for the corresponding clinical situation present.
