Comparative Analysis Of Abrasion Resistance In Relation To Different Temporary Acrylic Crown Material Using Toothbrush Simulator- An In vitro Study

Objective: The aim of this study is to compare the abrasion resistance of different temporary acrylic crown materials using a toothbrush simulator. Materials And Methods: This study was conducted using four different groups of temporization materials such as pro temp, tooth color acrylic material., heat cure acrylic material, Computer aided design and computer aided manufacturing (CADCAM) acrylic material. They were kept in a toothbrush simulator which stimulates 3-dimensional brushing. Before and after the intensity of abrasion was measured using a profilometer. The results were analyzed using SPSS statistical analysis. Results :By analyzing the range of abrasion it can be said that heat cure acrylic material and Computer aided design and computer aided manufacturing (CAD-CAM) acrylic material has better abrasion resistance compared to pro temp and tooth color acrylic material. There are significant differences in the group (P<0.05). Conclusion: Heat cure acrylic material and Computer aided design and computer aided manufacturing (CAD-CAM) acrylic material has better abrasion resistance.
