Quantitative wear measurement of posterior composite resins.

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