Use of Addition Silicones in the Final Impression of A Fixed Prosthesis

Abstract

Background: Addition silicones were introduced in 1970, and since then, they have not ceased to undergo improvements and changes for which they occupy an important place as the impression material of choice in fixed prostheses. Introduction: Nowadays, additional silicones are cataloged as the most used materials for dental treatments since they can capture minimum details and offer a variety of viscosities to be used in dental practice. Objective: To determine the main theoretical bases available on using addition silicones as the material of choice for taking definitive impressions for elaborating fixed prostheses. Methods: Scientific research articles, review articles, and clinical case studies published in journals indexed in Latindex, Scielo, Google Scholar, West Indian Med, Pubmed, and Dialnet were considered. Results: Addition silicones represent the essential impression material for the successful development of a fixed prosthesis, a therapeutic alternative to reduce dental extractions, bone resorption caused by partial edentulism and the use of conventional partial prostheses, improving the lifestyle of patients with fixed prostheses. Conclusions: According to several authors, silicone is the material with the best reproduction of details, which guarantees success in our treatments in fixed prosthodontics.
