Excessive wear  compromises the function of the restored teeth. As  wear measurements in-vivo are complicated  and time-consuming, different wear simulation  devices and methods have been developed. They are  meant to simulate processes that occur in the mouth  during mastication. A round robin test that  evaluated the wear of 10 materials with five  simulation methods showed that the results were not  comparable. When correlating material properties to  the wear results of 24 composite resins with a  specific wear method, some physical parameters could  be identified and incorporated into a wear formula  to predict wear for this method. The wear method  should not only efficiently generate reproducible  data but the data should also correlate with  clinical wear rates. A huge database on clinical  wear of different composite resins and amalgam was  used to compare wear with six laboratory methods.  Only one method showed an acceptable correlation  with clinical situation. The clinical wear data  revealed that to date no composite resin is as wear  resistant as amalgam.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838362557\"\u003e\u003ch3\u003eCan Laboratory Methods Predict Wear of Fillings and Crowns in Patients ?\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838362557","offer_id":39499101438045,"sku":"9783838362557","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/1b33969b-bd3c-499c-a6fb-66dd78af415e.jpg?v=1775627026","url":"https:\/\/shop.autorenwelt.de\/products\/wear-of-dental-restorative-materials-von-siegward-heintze","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
