The present invention is an anterior tooth 12 and a posterior tooth consisting of a root portion which is placed in the denture frame (1) forming the gum portion of the denture, and a crown portion extending to the upper or lower side of the root portion exposed to the outside of the denture frame (1). An artificial tooth (10) comprising: a direction indicator (50) for firmly fixing the artificial tooth (10) to the denture frame (1) on the tongue or bottom surface of the artificial tooth (10). The direction display part 50 is further formed on the tongue surface or the bottom surface of the root portion in a longitudinal direction along a predetermined depth, and the resin of the denture frame 1 is filled to the denture frame 1. Resin filling groove 52 for fixing the artificial teeth； It is formed extending from the front end side of the resin filling groove 52 to the midline side, formed by recessing to a predetermined depth to the direction indicating groove 54 for indicating the filling direction of the filling of the resin and artificial teeth； . According to the present invention, as compared to the general artificial teeth is firmly fixed to the artificial teeth implanted in the denture frame can minimize the damage of the user due to the dropping of artificial teeth, the effect of strengthening the cohesion of artificial teeth There is. In addition, the gum guide groove and the direction display wall is formed in the artificial teeth, the operator can easily check the direction of the anterior and posterior to the naked eye during the placement of the anterior and posterior teeth has the advantage that the work efficiency is improved.본 발명은 틀니의 잇몸부를 형성하는 틀니 프레임(1)에 식립되는 치근부와, 상기 치근부의 상측 또는 하측으로 연장되어 틀니 프레임(1)의 외부로 노출되는 치관부로 구성되는 전치(12)와 구치(14)를 포함하는 인공치아(10)에 있어서, 상기 인공치아(10)의 설면 또는 바닥면에는, 상기 틀니 프레임(1)에 상기 인공치아(10)를 견고하게 고정하는 방향표시부(50)가 더 구비되며, 상기 방향표시부(50)는, 상기 치근부의 설면 또는 바닥면에 세로방향을 따라 일정 깊이 만큼 함몰 형성되며, 상기 틀니 프레임(1)의 수지가 충진되어 상기 틀니 프레임(1)에 인공치아를 고정하는 수지충전홈(52
