Fiberotomy
Fiberotomy
A fiberotomy is an orthodontic surgical procedure designed to reduce the tendency of tooth rotation back to their original position after being corrected by dental braces and other treatments. A fiberotomy involves severing the fibers that attach the tooth to the bone via the gum. The fibers act much like twisted rubber bands and releasing the tension between the fibers and the tooth reduces the forces that attempt to pull the tooth back to its original position.
A thin-bladed instrument such as the periotome shown, a scalpel, or piezoelectric handpiece can be used to detach the periodontal attachment fibers (shown enlarged) above the bone level, to prevent elastic rebound—where the elastin fibers pull teeth that have been orthodontically rotated back to their original position.
