This review was based on articles searched through the MEDLINE and PubMed databases. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Elastomeric impression materials are currently one of the most popular options for definitive impressions in fixed prosthodontics.3,4 Among available elastomeric materials in the market, the polyvinyl siloxanes and polyethers are used most frequently.5 Polyvinyl siloxane (PVS) was introduced as a dental impression material in the 1970s. Recently, new elastomeric impression materials with very high elastic recovery and high tear strength have been introduced. Perhaps the greatest challenge clinicians face while capturing an impression is achieving complete reproduction of the prepared finish line, particularly with sub- or equigingival margins. • 1973 First moldable acrylic material.

Flashcards. Proposal. Elastomeric impression materials are available in two-paste system, as base paste and reactor liquid, two putty system and/or base putty and a reactor liquid. The intraoral scanner is a device that … The elastomeric impression materials are most widely used in the restorative dentistry due to multiple advantages like good reproducibility, elastic recovery, and dimensional stability . Normally, having more base materials in the mixture tends to increase the working and setting times. Whether impression is diagnostic or taken for provision of final restoration, its accuracy is crucial for the ultimate outcome. Publication date : 2000-12. Working time and setting time decrease as the filler content in the materials increases. Life cycle. This review presents a survey of the most clinically relevant physical properties that characterize final impression materials and their interactions with the products they are commonly in contact with.

In the light of these facts, a study was planned to evaluate the elastic recovery of various elastomeric impression materials on autoclaving and comparing it to the currently practiced method of chemical disinfection. 3. It can be concluded that both elastomers are superior and alike. Browse. Start studying Chapter 46 Test Review. The clinical significance of these materials, physical and mechanical properties are also emphasized. Also, the articles were published between the years 2010 and 2019. The present review on the accuracy of elastomeric impression materials on repeated pours would suggest that addition silicones and polyethers to a certain extent were least affected with delay in pouring the impression. The objective of this review is to provide comprehensive, exhaustive and up-to-date information on impression materials and soft tissue procedures, which will facilitate the dentist’s daily work in taking impressions to make various restorations. STUDY. CRAIG Department of Biomaterials, School of Dentistry, University of Michigan, Ann Arbor, Michigan 48109 Adv Dent Res 2(l):51-64, August, 1988 ABSTRACT Major advances in impression materials and their application have occurred during the last decade, with greater emphasis being placed on rubber impression materials than on dental … High accuracy dental impression is usually a first step during fabrication of indirect restorations that have to be seated in or on prepared teeth. Professor, Bharati Vidyapeeth Dental College, Pune 411043. Affecting the accuracy of the intraoral scanner. Dent Mater 2008;24:951-956. The article mentions the composition and the most important properties of the elastomeric impression materials used in dental practice. PLAY. Learn. General information Status : Withdrawn. www.indiandentalacademy.com 76. Gravity. The tensile properties of 17 hydrophilic impression materials with different consistencies were compared. The majority of impression techniques are comprised of different viscosity impression materials. St. Louis:Elsevier; 2006. p. 270-312. Purpose. Elastomeric impression materials offer high elastic recovery and acceptable flexibility on removal of the impression from the mouth . Altering the base/catalyst ratio will change the curing rate of these impression materials. Impression materials that have been exposed to infected saliva and blood provide a significant source of cross contamination[1]. Of particular interest has been the effect of disinfection solutions on the qualities of impressions and the biocompatibility of impression materials. Review of literature: Pre and post set hydrophilicity of impression materials were evaluated (j prosth 2007) Hydrophilicity of one polyether,4 A silicone & 1 C silicone were evaluated pre and post setting under simulated conditions.

Although new elastomeric impression materials have been introduced into the market, there are still insufficient data about their mechanical features. Aust Dent J 23:178, 1978. Elastomeric materials were intended for impressions for inlays, crowns, and FPDs. Associate Professor, Sinhgad Dental College, Vadgaon (Bk), Pune 411041. ing hydrophilicity for elastomeric impression materials; silicone is less hydrophilic than polysulfide, which in turn is less hydrophilic than polyether ( Pratten and Craig, 1989 ). elastomeric impression materials.However lack of the knowledge about the various techniques for making impressions with polyvinyl siloxane will lead to failure in impression making. Recently, new elastomeric impression materials have been introduced, with the claim of very high elastic recovery and high tear and tensile strengths. Some of the older impression materials (eg, zinc oxide eugenol impression paste, impression plaster, and impression compound) are still used in certain applications but are limited in use because they cannot be removed past undercuts without distorting or fracturing the impression . Thiol- and allyl-functionalized siloxane oligomers are synthesized and evaluated for use as a radical-mediated, rapid set elastomeric dental impression material.
