The Trephine Basic Kit provides a small set of high-quality, closely grouped trephine drills. These tools are designed specifically for creating cylindrical bone grafts quickly and accurately and for removing defined bone sections. These trephine drills have a depth of 10 mm and have been developed specifically with mandibular surgery and implantology in mind. Thanks to the well defined laser depth marks at 2 mm intervals, the medical practitioner can accurately monitor the depth of drilling as he or she works.
