A method for manufacturing a dental extraction socket shaping aid. First, a three-dimensional computer tomography device is used to obtain a three-dimensional image of a target tooth of a patient, and then an image processing device is used to construct a three-dimensional model of the target tooth according to the three-dimensional image, and A boundary line between the crown and the root of the three-dimensional model is defined, and the side of the boundary line facing outward is defined as an upper boundary line, which is a predetermined length away from the upper boundary line toward the root of the three-dimensional model It is defined as the lower boundary line and forms an arc-shaped curved surface with the width tapering from the upper boundary line to the lower boundary line, and then a partial model from the crown to the arc-shaped curved surface is extracted from the three-dimensional model, Then a three-dimensional molding device is used to make a dental extraction socket shaping aid with the arc-shaped curved surface according to the partial model.一種拔牙窩塑形輔具的製造方法,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,並形成一從該上邊界線朝該下邊界線寬度漸縮的一圓弧形曲面,再從該三維模型擷取出從牙冠至該圓弧形曲面的一局部模型,然後利用一三維成型設備根據該局部模型製出一具有該圓弧形曲面的拔牙窩塑形輔具。
