Facebow, Headgear (also known as: Night Brace, Cervical Gear)- Facebows are wire appliances used to move your upper molars back in your mouth which creates room for crowded or protrusive anterior teeth. Generally, the facebow consists of two metal parts which have been attached together. The inner part is shaped like a horseshoe. This part goes in your mouth and is connected to your buccal tubes. The outer part has two curves. The curves go around your face, and connect to the breakaways or high pull headgear. To properly use the product, the inner bow needs to be inserted into your buccal tubes. An elastic neck band is placed around the back of the neck while the triangular cast offs on both sides of the neck band are attached to the outer bow of the headgear. Completing the apparatus is a plastic safety strap that is placed over the neck band and onto the outer bow of the headgear.

Ligating Module (also known as O-Ring)- A small plastic piece, shaped like a donut, which is used to hold the arch wires in the brackets on your teeth.

Lip Bumper - A lip bumper is used to push the molars on your lower jaw back to create more space for other teeth. It also allows the arch to expand outwards making room for crowded teeth. The lip bumper consists of an arch wire which is attached to a molded piece of plastic. You mount the arch wire in the buccal tubes on your lower jaw, and plastic piece rests against your lips. When you eat or talk, you push the plastic piece back which pushes on your molars. That pushes your molars back.
