Description
Introduction
For both fully and partially edentulous patients undergoing rehabilitation with Osseo integrated implants, precise impression-making is a critical component for the long-term effectiveness of dental implants.1
The long-term viability of an implant depends on a number of factors. Incompatibility between the prosthesis and implant components, which can arise from an inaccurate impression, can lead to issues such as implant fracture, loss of osseointegration, screw fracture, and loosening of the screws.2 Fabrication of an accurate cast is significant for proper prosthetic reconstruction. Impression accuracy is the key factor for this. The choice of impression tray, impression technique, impression material, number and angulation of implants have an impact on the correctness of the impression.
The accuracy of impressions is affected by3
· Impression technique,
· Polymerization shrinkage of the impression material,
· Number of implants,
· Implant angulation,
· The design and rigidity of the impression tray
· Splinting and non-splinting of impression copings
The passive fit of the implant prosthesis is one of the most important aspects of implant longevity that depends on a good impression technique. Variations in the prosthesis's passive fit can cause occlusal discrepancies, screw loosening, screw facture, increased plaque buildup, and implant fracture in addition to other issues including osseointegration loss.4
With reference to earlier research on the topic, the goal of this review is to draw attention to the challenges that physicians could face while taking an implant impression and to offer details on the right tools and methods for taking impressions that require the least amount of error.
A number of impression procedures have been suggested to produce a cast that guarantees a precise fit for prostheses on implants that are osseointegrated.
