Dental impression material
专利汇可以提供Dental impression material专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a dental impression material, consisting of ethylene-vinyl acetate copolymer and an oil and having characteristics of being readily flowable at a temperature for collecting an impression, sufficiently retaining the shape below about the bodily temperature and fixing as an elastomer.
CONSTITUTION: A dental impression material consisting of 20W80wt.% ethylene- vinyl acetate copolymer (EVA resin) and 80W20wt.% oil (e.g., cotton seed oil, coconut oil, whale oil, beef tallow oil, mineral oil or synthetic oil), and, as necessary, an additive (e.g., waxes or inorganic and organic filler). The vinyl acetate content of the EVA resin is preferably 20W50wt.%. The above-mentioned impression material is inexpensive with affinity for mucosal surfaces of the oral cavity and gypsum and can be readily used simply by, e.g., extrusion from a tube, without requiring skilled techniques. The accuracy in the reproducibility of tissue details in the oral cavity is high and sharp without any influence of exudates in the oral cavity. Furthermore, a change with time is not caused, since water is not contained.
