The new design of a tooth-replacement implant, comprising: a main body part and a root neck portion, wherein the root body portion has a plurality of lateral pore and a hollow through hole at the bottom. A collagen coated layer and an anti-bacterial coating layer are employed on the surface of the body portion root. The new design will increase bone contact area and enhance stability. The novel implant also decreases the nerve paralysis caused by perception and avoids the sinus perforation.本創作係有關於一種人工牙根植體,包括:一牙根本體部以及一牙根頸部,其中,該牙根本體部係具有複數個側面通孔及一底部中空通孔。並可形成一膠原蛋白塗佈層及一抗菌塗佈層於牙根本體部表面。藉此,本創作可增加與骨骼接觸面積並提昇穩定度,更避免人工牙根植體壓迫神經造成知覺麻痺,及破壞上顎竇膜。1‧‧‧人工牙根植體2‧‧‧牙根本體部21‧‧‧細螺紋部22‧‧‧圓弧螺紋部23‧‧‧側面通孔3‧‧‧牙根頸部31‧‧‧牙冠接合部位
