Introduction: Nanocomposite has been developed as a dental restoration. Nano-scale filler can result in high mechanical properties and good esthetic. Nanofiller materials such as partially stabilised zirconia (PSZ) has been recommended for dental use. This form of zirconia can be stabilised by the addition of several different oxides such as magnesia and calcia. Chitosan as a coupling agent was able to increase the nanocompositeâs mechanical properties. The purpose of this research was to evaluate the nanocompositeâs hardness value with and without the addition of chitosan as a coupling agent as well as a different stabiliser of zirconia filler. Methods: Procedures of this research consisted of several stages which were the fabrication of nanocomposite and mechanical properties measurement using the Vickerâs hardness testing. Results: The nanocompositeâs hardness value (kg/mm2) with zirconia filler stabilised by MgO without the addition of chitosan was as much as 5.09 and with the addition of chitosan was 7.51; the nanocomposite âs hardness number with zirconia filler stabilised by  CaO without the addition of chitosan was 8.16 and with the addition of chitosan was 13.13.  The results were then analysed statistically using the Analysis of Variance (ANOVA) test and showed a significant difference between all of those data groups. Conclusion: The addition of chitosan as well as different stabiliser (MgO and CaO) of Zirconia filler had affected the nanocomposite âs hardness value.

Introduction: Tooth restoration and implant-supported was one of the methods to overcome the free end cases. Abutment and implant are two components that are fused together by a screw. Therefore, the main problem to solve are loosened screw and implant or abutment fracture because of increasing unpredictable potential force on the implant, abutment, and screw. The purpose of this research was to describe the distribution stress between the connection of the body of implant and abutment on the submerged and non-submerged design of the implant supported bridge. Method: The submerged and non-submerged design implant have been analyzed using the Finite Element Method under lateral and vertical static load for 180 N. The numeric model for lower jaw posterior segmented bone was determined by computed tomography, and the load measurement was performed to observe the distribution at the connection between the body of implant and the abutment of the implant supported bridge submerge and non-submerged design. Results: At the lateral load, the distribution strength value was 1.562x107 Pa, whilst for the non-submerged was 9.63x107Pa. At the vertical load, the distribution strength value was 1.038x107 Pa, whilst for the non-submerged was 3.342x107Pa. At the load of 180 N towards the vertical and lateral on the supported implant bridge, the distribution strength value had a smaller scale compared to the ultimate tensile strength (UTS), which was 1040 MPa (1.04 x 109 Pa). Conclusion: Both of the design including the secondary component (abutment) was safe to used as the supporting implant bridge.

Introduction: Acrylic resin is still the most commonly used denture base material due to its ideal properties. However, acrylic resin denture fractures are still considered a major unsolved problem thus the addition of nanoparticles as filler was performed to increase its mechanical properties. The purpose of this study was to discovered the effect of nanoparticles TiO2 on the flexural strength of acrylic resin denture plate. Method: This study used 27 heat-cured acrylic resin specimens sized 65 x 10 x 2.5 mm. The samples were divided into three concentration groups (n = 9), the control group; 1% of nanoparticles TiO2; and 3% of nanoparticles TiO2. The flexural strength was tested using the Universal Testing Machine. All data were analysed using the one-way ANOVA test with 95% confidence level then continued with the Least Significant Difference (LSD) test. Results: There were significant flexural strength differences in different concentration of nanoparticles TiO2. The highest flexural strength value was found in the 1% of nanoparticles TiO2 group (106.99 ± 6.09 MPa), whilst the lowest flexural strength value was found in the 3% of nanoparticles TiO2 group (91.64 ± 5.38 MPa). Significant flexural strength difference was found between the control group and the 1% of nanoparticles TiO2 group, and also between the 1% of nanoparticles TiO2 group with the 3% of nanoparticles TiO2 group (p < 0.05). Conclusion: From this study can be concluded that concentration of 1% of nanoparticles TiO2 was able to increase the flexural strength of acrylic resin denture plate.

Bond strength towards dentine is a critical factor for composite restoration success. The purpose of this research was to obtain data on self-adhered composite bond strength to tooth dentine. This research was an experimental laboratory research that used 10 third molar teeth as samples. The teeth were prepared by thinning its mesial part until it reaches dentine layer. The sample was divided into two groups, each consisting of 5 teeth. In group I was applied self-adhered composite with Fusio® Liquid Dentine brand, whereas group II was applied conventional composite with Ivoclar Te-Econom Flow®. The applied composite had a cylindrical shape with 6 mm diameter. The sample was then placed on the test arm. The shear bond strength test method then conducted on Universal Testing Machine (UTM). Obtained data was tested using Two-tails Independent t-Test (α = 0,05). The results showed the average of self-adhered composite bond strength to dentine is 1,8878 ± 0,2859 MPa and conventional composite for 4,43552 ± 0,49472 MPa. The data showed that the self-adhered composite bond strength to dentine is smaller than conventional composite. From this research can be concluded that there was bond strength difference between the self-adhered composite with conventional composites towards the tooth dentine.
