The application relates to a device and a method for securing a dental implant (2) in the bone tissue of a patient. The device comprises an internally threaded guide sleeve (4) with an interlock portion (7) that can engage an interlock portion (25) on a tubular mounting guide (24). A holder (10) comprises a screw (15) complementary to the thread of the guide sleeve (4). The holder (10) is arranged to secure an implant (2) at one end of the holder (10). The tubular mounting guide (24) is placed in a hole (27) in a surgical template (26) and cemented in the hole in a desired angular position. The template is placed in the mouth of the patient. Through the hole (27) in the template (26), a hole into the bone is drilled. The dental implant (2) is secured on the holder (10) and the guide sleeve placed in the hole (27) of the template (26) such that the respective interlock portions (7, 25) interlock. The holder (10) is screwed through the guide sleeve (4) until the implant is screwed into the bone. The application also relates to a method for making the surgical template (26).
