Impression materials A brief introduction Dr saransh malot 2. The polyvinyl siloxanes are impression materials used in clinical dentistry due to several factors, such as handling characteristics, physical properties, and dimensional stability 5. 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 … The time measured from the start of mixing the impression material to the point where further manipulation will introduce distortion or inaccuracy is called the working time. The impression taken should be highly precise, thus, requiring specific care when manipulatingthese materials. This paper describes the development of an instrument for determining consistency, working time and setting time of elastomeric impression materials. The operating principle involves the application of a fixed compressive strain and the resulting stress is measured. Physical properties of the impression tray and its manipulation constitute important considerations in the impression process. Elastomeric Impression Materials: Factors to Consider. Dental impression making is the process of creating a negative form of the teeth and oral tissues, into which gypsum or other die materials can be processed to create working analogues. 14 There is usually a correlation between the working and setting times. Moreover, impressions created with this type of elastomeric impression material can be obtained by different impression … There are 4 groups of elastomers; polysulfide, condensation silicone, addition silicone and polyether; each differ in their setting mechanism and their physical and chemical properties. – They are clean and do not have an unpleasant taste or smell. Impression materials Elastic Chemical reactions Irreversible Alginate Elastomers Polysulphides Polyethers Condensation silicon Addition silicon Temperature change Reversible Agar hydrocolloid Chemical reactions Irreversible Plaster of Paris ZnO Eugenol Temperature change Reversible Impression … – Addition silicone impression materials are also called vinyl polysiloxanes and […] Addition Silicones – Addition silicones are the most popular type of elastomeric impression material, especially for crown and bridge impressions. The need for more satisfying impression materials promotes the development of elastomeric impression materials. – They are the most accurate, stable, and expensive impression materials. Elastomeric impression materials are in common use. Write short notes on: 6x5=30marks a) Wanderval forces b) Separating media c) Hydroscopic expansion d) Polymerization reaction Manipulation of VPS impression materials are critical and needs an understanding to achieve proper impressions. 1.
