An inventive implant handpiece (12) includes a head (14) having a round outer peripheral surface (20) which is concentric with a center axis of a drill bur (17) and has a predetermined length (H1 to H3) as measured axially of the drill bur (17). A surgical guide (11) has a guide hole (13) having a round inner peripheral surface to be opposed to the round peripheral surface (20) of the head (14). Since a drilling operation is performed with the head (14) fitted in the guide hole (13), the head (14) can be reliably uniquely guided to form an implant implantation hole as desired. Thus, the present invention provides an implant handpiece capable of accurately drilling a hole for formation of an implant implantation hole, and a surgical guide capable of guiding this handpiece.
