4. Insertion Tools and Implant Designs

To insert BOI implants a T-shaped osteotomy has to be cut into the bone. The instruments used for this are usually designed to cut either the vertical or the horizontal part. There are also instruments, however, that are designed to cut the vertical and horizontal parts simultaneously. Within limits these instruments can be replaced (e.g. with a tungsten carbide cutter) if required for intraoperative accessibility.
