The most important condition for a safe healing of a bone graft is a congruent and fresh contact surface of the implant area. The Transfer-Ring-Control I System allows for this precondition for the healing of vertical bone grafts in a simple and controlled manner. This system offers a selection of various instrument sizes and provides high flexibility for the extraction of bone rings. Depending on requirements, various sizes of Initial Bur Trephines, Trephines and Ablative Burs are available. With the aid of the additional tungsten carbide bur, sharp bone edges can be smoothed precisely.
