A quantitative method for measuring the wear of posterior composite restorations has been developed. The system utilizes the comparison of die stone casts of restored teeth to a set of calibrated standards as a means of evaluating the wear on the restorations. The technique facilitates the determination of the actual rate of clinical wear. This method, therefore, can be used to relate quantitatively the performance of one material to another. Further advantages are that materials can be compared without being a part of the same study, and that direct comparisons can be made of a single restoration at two or more ages.
