Elastomeric impression materials are widely used in dentistry to obtain accurate impressions. The most recent group of these materials is the additional polymerised silicones which have been shown to produce great accuracy. An auto-mixing system has been developed to provide ease of manupilation. The material is mixed as it is syringed through a mixing tip. The dimensional accuracy of the material mix by this system is compared to that of a hand mixed material. Results show that the dimensional accuracy of this new material is good and the system easy to use. The limitations of the material are also discussed.
弹性印模材料在牙科中被广泛用于获取精确的印模。这类材料的最新品种是加聚型硅酮，已证明其能产生很高的精度。已开发出一种自动混合系统以方便操作。当材料通过混合头注入时会进行混合。将该系统混合的材料的尺寸精度与手工混合材料的尺寸精度进行比较。结果表明，这种新材料的尺寸精度良好且该系统易于使用。还讨论了该材料的局限性。
