The objective of the present invention is to appropriately form an implant cavity without forming a stent, to reduce cost and to shorten operative time. A guide tool (1), which guides a cutting bar that is mounted to a handpiece when forming an implant cavity at an implanting position of an implant, is configured by comprising a long handle part (11), a pole part (12) which supports a distal end side of the handle part (11) and a guide part (13) which guides the cutting bar at the distal end side of the handle part (11). The pole part (12) is configured so as to protrude from the distal end side of the handle part (11) in a direction opposite to a cutting direction of the cutting bar.本發明係一種引導治具，其係不形成定位板(stent)，可適當形成植入孔，進而可以低成本縮短手術時間者。於植入體之嵌設位置形成植入孔時，採用於引導安裝於手持件之切削棒之引導治具(1)，設置長條狀之把手部(11)、支持把手部(11)之前端側之標桿部(12)、及於把手部(11)之前端側中引導切削棒之引導部(13)之構成。又，標桿部(12)係採用自把手部(11)之前端側朝切削棒之切削方向之反向突出之構成。
