摘　　要：目的研究纳米银二氧化钛抗菌剂对口腔义齿基托树脂机械性能的影响。方法通过物理性能测试仪器方法,对添加不同浓度纳米银二氧化钛的口腔义齿基托树脂的弯曲强度、显微硬度和表面粗糙度等机械性能进行测试与评价。结果添加纳米银二氧化钛比例达到质量分数3%的基托树脂弯曲强度最大,添加纳米银二氧化钛比例达到质量分数5%的基托树脂的显微硬度和粗糙度最大。结论口腔义齿基托树脂中添加纳米银二氧化钛抗菌剂比例为质量分数3%时,其机械性能最佳。Objective To study the influence on mechanical properties of denture base resin mixed with Ag-embedded nano-TiO2.Methods The strength,microhardness and surface roughness of denture base resin mixed with different Ag-embedded nano-TiO2 concentration were measured according to the relevant testing methods.Results The bending strength of denture base resin mixed with 3% Ag-embedded nano-TiO2 was maximum.The microhardness and surface roughness of denture base resin mixed with 5% Ag-embedded nano-TiO2 was maximum.Conclusion The mechanical properties of denture base resin mixed with 3% Ag-embedded nano-TiO2 are the best.
