The facebows are wire devices used to move the upper molars to the back of the mouth to provide space for crowded or jutting out front teeth. It consists of two metal parts attached together. The inner part, which is horseshoe-shaped, is connected to the buccal tubes, a metal welded to the molar. The outer part contains two curves that go all around your face and is connected to the breakaways which strengthen the facebow. A flexible neck band is attached at the back of the neck with the triangular cast offs at the side of the neck band fastened to the outer bow of the headgear. A plastic safety strap is then placed over the neck band connecting to the outer bow of the headgear.
