摘要：
An implant includes a head portion, a neck portion, a threading portion and a coupling hole. The head portion is formed on a first end of the implant and the neck portion is formed on a second end of the implant. The neck portion has a conical face and a clipping portion. The conical face is located on an outer circumference of the implant. The conical face has a gradually-reduced diameter from the first end towards the second end. The clipping portion is located on the conical face. The threading portion is located on the outer circumference of the implant and between the head portion and the neck portion. By arranging the conical face and the clipping portion on the neck portion, gums and alveolus of a user receiving the implant may help to position the implant, achieving better coupling reliability.一種人工牙根植體,其包含一鑽頭部、一定位頸部、一螺紋部及一結合孔。該鑽頭部形成於該人工牙根植體之一第一端,該定位頸部形成於該人工牙根植體之一第二端。該定位頸部具有一斜錐面及一卡抵單元,該斜錐面設置於該定位頸部之環周面,該斜錐面沿該第一端朝該第二端形成漸縮錐度,該卡抵單元設置於該斜錐面。該螺紋部設置於該人工牙根植體之環周面,且位於該鑽頭部及定位頸部之間。藉由該定位頸部之斜錐面及卡抵單元的設置,使得覆蓋於該人工牙根植體的牙齦及齒槽骨亦能幫助定位該人工牙根植體,提升其結合可靠度。1...鑽頭部2...定位頸部21...斜錐面22...卡抵單元3...螺紋部4...結合孔40...開口41...嵌合部42...內螺紋部
