本发明提供一使用牙科光固化树脂组成物，不需技巧，平顺且简单地在短时间，特别是少于1小时，制造人工牙的方法，该人工牙具有优异的强度、耐磨性、硬度、低吸水性、美观性以及功能性等。;一制造人工牙的方法被揭示，包含以下步骤：(a)容纳一内含一自由基聚合有机化合物(A)、一填充物(B)以及一光敏性自由基聚合引发剂(C)的液态牙科光固化树脂组成物于一具有一可透光底面的成形容器，以及依据基于相关于一牙齿的三维CAD数据的每一个层的切片数据经由该成形容器的该可透光底面以一预定的形状图案利用光照射该成形容器中的该牙科光固化树脂组成物；(b)抬高形成于步骤(a)中的一个层的该固化树脂层，藉此使该液态牙科光固化树脂组成物流入该固化树脂层的该下表面和该成形容器的该底面之间的该空间，以及依据基于相关于一牙齿的三维CAD数据的每一个层的切片数据经由该成形容器的该可透光底面以一预定的形状图案利用光照射该固化树脂层的该下表面和该成形容器的该底面之间的该牙科光固化树脂组成物而进一步形成一具有一用于一个层的预定形状图案的固化树脂层；以及(c)重复该步骤(b)的该操作直到该目标的人工牙被得到。;[Solution] ;Disclosed is a method for producing an artificial tooth, which includes the steps of: (a) accommodating a liquid dental photocurable resin composition containing a radical polymerizable organic compound (A), a filler (B), and a photosensitive radical polymerization initiator (C) in a shaping container having a light permeable bottom face, and irradiating the dental photocurable resin composition in the shaping container with light in a predetermined shape pattern through the light permeable bottom face of the shaping container in accordance with slice data every one layer based on three-dimensional CAD data relating to a tooth to form a cured resin layer having a shape pattern for one layer; (b) lifting up the cured resin layer for one layer formed in the step (a), thereby allowing the liquid dental photocurable resin composition to flow into the space between the lower face of the cured resin layer and the bottom face of the shaping container, and irradiating the dental photocurable resin composition between the lower face of the cured resin layer and the bottom face of the shaping container with light through the light permeable bottom face of the shaping container in accordance with slice data every one layer based on three-dimensional CAD data relating to a tooth to further form a cured resin layer having a shape pattern for one layer; and (c) repeating the operation of the step (b) until the objective artificial tooth is obtained. |
