A brace or brace and bit is a hand tool used to drill holes, usually in wood. Pressure is applied to the top and the tool is rotated with a U-shaped grip. The U-shaped part is a kind of crankshaft. It gives the brace much greater torque than other kinds of hand drills. A brace can be used to drill much wider and deeper holes than can a gear-driven hand drill.
The application of braces moves the teeth as a result of force and pressure on the teeth. There are traditionally four basic elements that are used: brackets, bonding material, arch wire, and ligature elastic (also called an âO-ringâ). The teeth move when the arch wire puts pressure on the brackets and teeth.
