The invention discloses a kind of platform tooth pedestal,Comprising a first connecting portion,One second connecting portion and an axis hole,First connecting portion sequentially have a chimeric block,One tapered pole,And one hold tooth platform,Second connecting portion is connected with first connecting portion,Second connecting portion have a cylindrical body,Three convex blocks by cylindrical body protrude,And one annular groove set the outer peripheral edge of what cylindrical body,One end of cylindrical body is connect with tooth platform is held,Annular groove passes through three convex block,The respectively convex block is separated into a upper convex portion and once protrusion,Each convex block outer rim has a longitudinal groove,Axis hole penetrates through first connecting portion and second connecting portion. Annular groove and the longitudinal groove can increase adhesive agent flow effect before curing, make adhesive agent can more extensively, be more uniformly coated with what second connecting portion, increase the stability of platform tooth pedestal Hou in conjunction with artificial dental crown.本發明揭露一種支台齒基座,包含一第一連接部、一第二連接部以及一軸孔,第一連接部依序具有一嵌合塊、一錐形柱、以及一承牙平台,第二連接部和第一連接部連接,第二連接部具有一柱狀本體、三凸塊由柱狀本體凸出、以及一環槽設於柱狀本體的外周緣,柱狀本體之一端與承牙平台連接,環槽通過該三凸塊,將各該凸塊分隔成一上凸部及一下凸部,各凸塊外緣具有一縱向溝槽,軸孔貫通第一連接部及第二連接部。環槽與該縱向溝槽可增加黏著劑固化前的流動效果,使黏著劑可更廣泛、更均勻地塗佈於第二連接部,增加支台齒基座與假牙冠結合後的穩固性。
