The utility model relates to a abutment tooth component, which is used for mounting on a implant and grinded by a tool.The support teeth assembly includes the support teeth and the guide buffer.The abutment tooth comprises a positioning structure, an upper connecting part and a lower connecting part, and the positioning structure is arranged outside the upper connecting part.The upper connecting part is connected with the lower connecting part, and the lower connecting part is detachably connected with the implant.When the tool is grinding the guide buffer, the guide buffer is positioned on the abutment tooth by the inner positioning structure to reduce the displacement.Therefore, the use of grindable guide buffer and specific color coating layer can realize customization and achieve the effect of guide and shock absorption.本新型係一種支台齒組件，其用以安裝於一植體上且被一工具磨削。支台齒組件包含支台齒與導正緩衝件。其中支台齒包含定位結構、上連接部以及下連接部，定位結構設於上連接部的外側。上連接部銜接下連接部，且下連接部可拆卸地連接植體。導正緩衝件緊密接合定位結構與上連接部外，工具磨削導正緩衝件時，導正緩衝件藉由內側之定位結構定位於支台齒而減少位移。藉此，利用可磨削的導正緩衝件結合特定顏色的塗料層可實現客製化，還可達到導正、避震之效。
