| Intra-oral Restorative Materials Wear: Rethinking the Current Approaches | ||||||||||||||||||||||||
Sponsored by: Dental Materials | ||||||||||||||||||||||||
| Description: In the last ten to fifteen years the wear resistance of restorative materials has considerably improved. But some materials for prosthodontic use have shown unacceptable wear in clinical studies. To objectively quantify wear in clinical trials is a complex and difficult as well as time-consuming and expensive task. Therefore, wear simulation methods to predict the long-term clinical wear of restorative dental materials would be important; a prerequisite would be the validation of those methods. There are many wear simulation methods reported in the literature but all of them are lacking the evidence of their clinical relevance because prospective studies correlating in vitro with long-term in vivo results with identical materials are missing. Therefore, a state of the art and update on wear and wear simulation is necessary in order to be able to correctly interpret the outcome of wear simulation experiments. Technical problems involved with wear simulations will be addressed. In the proposed Symposium the following questions will be discussed: How to simulate wear (overview of existing methods) ? How to measure wear ? How to qualify and validate wear simulation devices ? In a final structured discussion with the panel, actual acceptance levels and future research needs should be defined | ||||||||||||||||||||||||
