摘要

本研究之研究目的為開發應用於製作牙科赝復元件之三維列印技術，以目前較為廣泛應用的牙科赝復元件為目標進行製作，如:人工牙冠、人工牙橋、人工牙根與人工牙根柱等。於製作前先進行動態光罩處理，再使用自行開發的光聚合氧化鋯陶瓷漿料進行陶瓷綠胚的製作，製作完成後的陶瓷綠胚則進行兩階段的高溫燒結後處理，以提升氧化鋯陶瓷綠胚的機械性質。透過本研究所開發的三維列印技術與光聚合氧化鋯樹脂進行製作出的牙科赝復元件具有三方向為23%的高溫收縮率，且其機械性質也大幅度的提升許多，再者，赝復元件複雜的外型也表現得非常精細與清楚，如:咬頭、微螺紋等特徵。

The aims of this study are to develop three-dimensional printing technology for fabricating the ceramic dental restoration devices such as the dental crown, dental bridge, dental implant and dental post. Firstly, the model of dental restoration device is sliced and produces mask images of each sliced layers by mask generation software. Secondly, the slurry including the zirconia powder, Plasticizer and photopolymer will be synthesized for fabricating the dental restoration devices by the three-dimensional printing system. After two stage sintering process treatment, the green parts made of zirconia oxide had an average shrinkage rate of 23% in three direction and excellent mechanical properties. In addition, the shape of dental restoration devices can be produced very clear and obvious such as cusp and micro screw.
