Abstract :

background: One of the successful methods of prosthodontic rehabilitation is Implants. Implant dentistry requires a multidisciplinary approach and proper prosthodontic planning to achieve a satisfactory result. Thus, the successful outcome of treatment largely depends on the accuracy of various impression techniques, materials used and osseointegration of implants. The main aim of implant impression is to accurately place implant analog/abutment corresponding to other structures in the dental arch without stressing the adjacent supporting tissue and teeth. The aim of work: This review aims to understand the accuracy of various important techniques regarding accurate reproducibility, dimensional stability, and material aspects. Methodology: The review is a comprehensive search of PUBMED from the year 1992 to 2016. The following search terms were used: Implants impression techniques, Direct impression technique, indirect impression technique, Impression material Conclusion: The passive fit of implant prosthesis is the ultimate factor in the long-term success of prosthesis. To achieve it a clinician should have sound knowledge of component and the impression material used, the impression techniques for a suitable impression procedure based on a clinical situation. Among impression material, vinyl polysiloxane is found to be most accurate compared to other impression material such as polyether, polysulfide, etc. More precision is seen with direct impression technique than indirect impression techniques. Keywords: Implants impression techniques, Direct impression technique, indirect impression technique, Impression material.
