The manufacturing method of one tooth-implanting accessory,The 3-dimensional image of the target tooth of a patient is obtained first with a three-dimensional computer tomographic apparatus,Recycle an image processor according to a threedimensional model of the 3-dimensional image construction target tooth,And the corona of the threedimensional model and a boundary line of root of the tooth are defined,And the side of the boundary line outwardly is defined as a upper border line,It will be defined as boundary line from one predetermined length of root of the tooth direction distance from the upper border line towards the threedimensional model,To capture the partial model between the out-of-bounds what upper border line and the following boundary line from the threedimensional model,Image processing is carried out to the partial model again,The partial model is set to become a final mask hollow and with a predetermined thickness,Right Hou produces a plant tooth accessory according to the final mask using a three-dimensional modeling machine.一種植牙輔具的製造方法，首先利用一三維電腦斷層掃描設備取得一患者的一目標牙齒的三維影像，再利用一影像處理裝置根據該三維影像建構該目標牙齒的一三維模型，並界定出該三維模型之牙冠與牙根的一交界線，並將該交界線朝外的一側定義為一上邊界線，將從該上邊界線朝該三維模型的牙根方向距離一預定長度處定義為一下邊界線，以從該三維模型擷取出界於該上邊界線與該下邊界線之間的一局部模型，再對該局部模型進行影像處理，使該局部模型成為一中空且具有一預定厚度的最終模型，然後利用一三維成型設備根據該最終模型製出一植牙輔具。
