Abstract
Background: The sharpening of tooth preparation skills must be obtained during the pre-clinical period of dental education, supported by the development of adequate learning media. One of the developments is using dental models made from self-cured acrylic. However, mechanical properties such as the compressive strength, elastic modulus, and surface hardness value of self-cured acrylic is still smaller than tooth enamel, so it is necessary to add certain materials to improve the characteristics. One of the material that can be added is nanohydroxyapatite from bovine bone synthesis. Purpose: To determine the compressive strength, elastic modulus, and surface hardness value of self-cured acrylic with the addition of nanohydroxyapatite from bovine bone. Methods: This study used True Experimental Study with a post-test only control group design. This study involved self-cured acrylic as the control group, and self-cured acrylic with the addition of 2%, 5%, and 8% nanohidroxyapatite from bovine bone as the treatment group. Results: Based on the ANOVA test, obtained p <0.005 showed the difference between compressive strength, elastic modulus, and surface hardness value of the control group and the treatment group. The higher mean number of mechanical properties is in the sample with addition of 8% nanohydroxyapatite, compressive strength (94,85 MPa), elastic modulus (6015,77 MPa), surface hardness (18,30 VHN). Conclusion: There was an increases in the compressive strength, elastic modulus, and surface hardness value of self-cured acrylic with addition of nanohydroxyapatite from bovine bone as basic material for dental models in prosthodontics clinical skills learning.
