Disclosed is an attachment for fixing a denture, in which a slantly implanted fixture and a denture are freely coupled by adjusting an angle of the denture with respect the fixture implanted in an alveolar bone. The attachment has a simple structure so that it is economical because productivity can be improved, can improve workability because an entire assembly can be implemented through a simple operation, and can be stably used for a long period of time without becoming disassembled by itself through firmly maintaining an assembled state. The attachment includes a joint member having a rod shape, in which the denture is fixed to the joint member and an abutment provided at an outer lower part thereof with a coupling part coupled to the fixture, and provided at an upper part thereof with an accommodating part to accommodate a lower part of the joint member.本發明揭示一種假牙固定用之附著體,其中傾斜植入固定物及假牙係藉由相對於植入齒槽骨中之該固定物來調整該假牙之角度而自由地耦接。該附著體具有簡單結構以使得其為經濟的,因為生產率可得以改良;可改良可加工性,因為可經由簡單操作來實現整體組裝;且可經由牢固地維持組裝狀態來穩定地使用長期時間而不會變得自身拆開。該附著體包括:具有桿形之接頭構件,其中該假牙係固定至該接頭構件;以及支座,在該支座之外下部處具備耦接部,該耦接部耦接至該固定物,且在該支座之上部處具備容納該接頭構件之下部的容納部。1‧‧‧附著體5‧‧‧接頭構件6‧‧‧支座7‧‧‧容納凹槽8‧‧‧突出部9‧‧‧引導凹槽10‧‧‧凸形部11‧‧‧下端12‧‧‧上端13‧‧‧連接部
