本文主要發展高強度奈米醫用樹脂、裂縫修補假牙的強度檢測方法、Ansys分析及氫氧基磷灰石（簡稱HA）薄膜之真空鍍膜技術，可以解決醫師因臨床研究時發現假牙品質不佳之問題。而本實驗導入田口品質工程方法，設定L_9（3^3）的直交表，尋找拉伸檢測之最大破壞強度及楊氏係數的最佳因子與水準。其醫用樹脂修補試片利用萬能試驗機進行抗壓檢測及硬度試驗機進行附著力檢測，由檢測數據制定最佳配方參數。最後利用真空鍍膜技術在試片及假牙的表面HA薄膜鍍層，可以增加其抑菌能力。經本實驗各項研究成果，可以歸納出其結論，在田口方法中的拉伸檢測結果其最佳參數為添加SiO_2粉末，百分比為3%，烘烤溫度100℃，而抗壓檢測結果最佳參數為添加SiO_2粉末，比例為2%，烘烤溫度100℃。在抑菌檢測上，其假牙真空鍍膜HA薄膜有良好抑菌效果（比未鍍層提高3－4倍）。

This paper highlights the importance of high-strength nano-medical resin, crack repair denture strength testing method, Ansys analysis and vacuum coating technology of hydroxyl apatite( HA) thin film, which can solve the problem of dentures caused by poor quality during clinical research. In this experiment, Taguchi's quality engineering method is introduced, and the orthogonal table of L9 (3^3) is set to find the optimum factors and levels of the maximum destructive strength and Young's modulus of tensile testing. Next, the universal testing machine is used to carry out the compression test of the medical resin piece in repairing tooth cracks; that is, to test the adhesion of the medical resin coated test piece according to the specifications, and formulate the test procedure and the best formula parameters based on the experimental data. Finally, the vacuum coating technology is used to coat the surface of the test piece and denture with HA film, which can increase its antibacterial effect. Through various research results of this experiment, this paper concludes that the best parameters for the tensile test results in the Taguchi method are the addition of 3% SiO_2 powder, and the baking temperature is 100℃, while the best parameters for the compressive test results are Add SiO_2 powder in a proportion of 2%, and the baking temperature is 100oC. In terms of antibacterial detection, the vacuum-coated HA film on dentures demonstrates a good antibacterial effect (3-4 times higher than that without coating).
