[Purpose] from teeth model of the current stage, the mouthpiece type for teeth model compatible with the correction of the next stage, efficiently and teeth model orthodontic mouthpiece type can be produced made that at low cost with high quality to provide a manufacturing equipment and manufacturing methods in the teeth model of. [Configuration] gums model so that the position is possible variations of each tooth model in the current stage teeth model (teeth model which is formed on the basis of the shape as shown dentition shape of the current stage of the patient is softened inside the deployable support of the current stage teeth model has) (and two or more support pieces that make up the orthodontic mouthpiece type made for teeth model of the production tool), the distance between them left and right, a production tool having a connecting portion for connecting to allow variations in the direction between the front and back or their (those containing a screw mechanism). Further, a method for producing the next step teeth model using such production tool.FIELD 1【目的】現段階の歯列模型から、次段階の矯正に適合するマウスピース型用歯列模型を、高品質に効率的に且つ低コストで作製できる歯列矯正マウスピース型作製用歯列模型の製造用具と当該歯列模型の製造方法を提供する。【構成】患者の現段階の歯列形状を示すように前記形状に基づいて形成された現段階歯列模型(歯列模型中の各歯模型の位置が変動可能なように歯茎模型が軟化されている現段階歯列模型)の内側に配置可能な支持体(歯列矯正マウスピース型作製用歯列模型の製造用具)を構成する2つ以上の支持体片と、それらの間の距離が左右、前後又はそれらの間の方向に変動可能なように連結する連結部(ネジ機構部を含むもの)とを備えた製造用具である。また、このような製造用具を使用して次段階歯列模型を製造する方法である。【選択図】 図1
