Components for guided threading of bone

摘要

A combination of a guide sleeve for a surgical template, a drill, and a thread forming tool is disclosed. The guide sleeve has a guide surface for guiding the thread forming tool. The drill has at least one cutting edge for cutting a recess in bone. The thread forming tool has a thread forming section for forming at least one thread in bone, and a guide section for guidance by the guide surface of the guide sleeve, the thread forming section comprising an apical portion, and a coronal portion. A maximum diameter of the apical portion of the thread forming section is smaller than or equal to a maximum diameter of the cutting edge of the drill.

1. A method of placing an implant, the method comprising:
positioning a surgical template at a surgical site; positioning a guide sleeve with a guide surface in the surgical template; inserting a drill having a cutting edge through the guide sleeve; drilling a recess in the bone while the drill is guided by the guide sleeve; inserting a thread forming tool into the guide sleeve, wherein the thread forming tool has a thread forming section, the thread forming section having at least one thread for forming at least one corresponding thread in the bone, and a guide section, the thread forming section comprising an apical portion including the at least one thread, and a coronal portion, the thread forming tool having a maximum diameter of the at least one thread of the apical portion of the thread forming section that is smaller than or equal to a maximum diameter of the cutting edge of the drill; guiding the guide section of the thread forming tool with the guide surface of the guide sleeve before the thread forming section of the thread forming tool starts forming the corresponding thread in the recess; forming the corresponding thread in the bone while the guide section of the thread forming tool is guided by the guide surface; and inserting the implant in the threaded recess, wherein the implant has a bone tissue apposition surface comprising an apical portion and a coronal portion, and wherein a maximum diameter of the thread forming section of the thread forming tool is smaller than a maximum diameter of the bone tissue apposition surface of the implant.
