Cheek teeth provide very good stability for tension wires, usually placed between the 06 and 07 teeth (the second and third premolar). To achieve this, the skin is clipped, surgically prepared and a short arthroscopy sleeve with a trocar or obturator is advanced into the mouth via a stab incision. This technique minimizes hemorrhage, which can be a problem when the tissue is cut with a scalpel. A drill bit is then introduced through a protective drill guide and a hole is prepared between the two cheek teeth.
