Abrasive wear, tensile strength, and hardness of dental composite resins--is there a relationship?
The in vitro abrasive wear resistance, tensile strength, and hardness of seven widely used composite restorative resins have been measured. Findings indicate that the values of tensile strength and hardness are not related to the measured abrasion rates. It is apparent that abrasive wear is a complex phenomenon and that materials which have high values for strength and/or hardness do not necessarily have high resistance to abrasive wear.
