A COMPREHENSIVE REVIEW OF BASIC IMPRESSION TECHNIQUES FOR IMPLANT RESTORATIONS

Dental implant, a fixed prosthesis widely used to replace the missing natural tooth for the rehabilitation of both partially and fully edentulous patients. In modern dentistry, dental implant plays a vital role in restoring the form, function, and esthetics of the patients. Passive fit between the implant abutment interfaces is one of the most significant pre-requisites of implant - supported prosthesis. Although achieving an absolute passive fit is not yet possible, providing the best possible fit is fundamental to prevent future biologic and mechanical complications that include screw loosening and/or fracture that can lead to implant failure. An accurate impression relates the coronal structure of an implant to other structures of the oral cavity and avoiding instabilities in the prosthetic device and thereby provides long-term success. Here in this article, a brief overview of implant impression techniques is outlined.
