摘要

三維列印應用範圍相當廣泛且相關研究眾多，但較少有針對牙醫方面的研究。為解決傳統假牙繁雜的製造過程且易造成邊緣之崩裂，讓細菌容易孳生造成病人不適和後續的醫療糾紛，三維列印是假牙製造的另一種選擇。本研究主要探討贋復元件之強度，利用有限元素分析軟體(Ansys-WorkBench)分析人體口腔在咀嚼時牙齒所受之應力分佈及牙齒強度。本實驗採用二氧化鋯粉來做為三維列印漿料之主料，獲得贋復體後測量其抗壓數據與模擬驗證準確性，並測量贋復體之牙冠邊緣厚度與內建模型之誤差。此項研究有助於假牙牙冠邊緣的強度探討，以其利用三維列印製造出強度更高，不易崩壞的假牙。

Currently, stereolithography (SL) technology is getting popularly to apply in different kinds of industries. However, there are fewer studies discussed on the related topics of dental. In order to solve the crack problem of the dental manufactured by the complex-traditional manufacturing process, three dimensional printing will be a good choice. The main target of this study is to study the strength of dental, and verified by the Ansys-WorkBench simulating the chewing action in human mouth. The material in the experiments is zirconia based slurry. After the prosthesis element is obtained, the compression stress is compared with the result obtained by finite element analysis. The bottom outline of the crown prosthesis is also checked with the CAE model. The results of this study are helpful to get prosthesis with high strength and prevent the crack.
