This creation is a kind of related spiral osteotome of what, particularly relates to a kind of tool for planting tooth with what, can stablize and neat cutting dental cavity, so that implant is consolidated and is placed in dental cavity. It is mainly to be made of chiseled body, spire and rotating portion, the chiseled body system is a column, position what lower section forms spire, it is to be apered to cone cell downwards, and what top end is equipped with rotating portion, spinner handle can be corresponded to and rotated together, when to being dug under tooth, dental cavity can be dug by the tapering of spire bottom end, then persistently protrude into tooth depths along the lines of spire, and it is synchronous tooth bits are pushed fill up arround tooth meat, to consolidate dental cavity foundation, and the dental cavity of cutting is enable to open according to required depth brill, make foundation neat and consistent, will not deviate.本創作係有關於一種螺旋式骨鑿,特別是指一種用於植牙之工具,能穩定且整齊的開鑿牙洞,使植體能穩固置入牙洞內。其主要係由鑿體、螺旋部及旋動部所組成,該鑿體係為一柱狀,位於下段形成螺旋部,其係向下漸縮成錐狀,並於頂端處設有旋動部,可對應旋桿而一起轉動,當對牙齒下鑿時,能藉由螺旋部底端之錐部開鑿牙洞,再延著螺旋部之紋路持續伸入牙齒深處,且同步將齒屑推擠填補入周遭牙肉,以穩固牙洞根基,並使開鑿之牙洞能依所需之深度鑽開,使根基整齊一致,不會偏移。
