How To Determine The Typicality Of Test Samples When Evaluating The Relative Performance Of Dental Impression Materials?

Dental impression materials are mainly used to make the female die to record the morphology and relationship of various tissues in oral cavity, or to assist in obtaining clear 3D images of teeth. When evaluating the relative performance, it is necessary to select the typical model which may cover all the conditions of the product under application by combining the characteristics of the product such as composition and polymerization mechanism etc. as the typical sample for test and study; if the full-performance test for product is conducted, it is necessary to consider the characteristics such as product performance and technological process to select the model with the worst performance among the product under application as the typical model.
