The article focuses on a study on the in vivo measurement of occlusal wear resistance of restorative materials. The method was used to evaluate the wear resistance of three restorative materials, Adaptic®, amalgan and Estic® microfill in a 13 month clinical trial. The subjects were five healthy volunteers 21 to 28 years old with intact dentitions. A profilometer is used to record the loss of vertical dimension of the test material occlusal surface. The measurement technique used in this study proved extremely accurate. Results showed that the loss of material due to attrition and abrasion was significantly more with Adaptic® than with the microfill. Estic® was found comparable to amalgam in wear resistance.
