Tunnel Preparation
A furcation management procedure in which the furcation of a multi-rooted tooth is surgically opened to create a through-and-through channel for hygiene access.
Full Definition
Tunnel preparation is a surgical treatment for Class III furcation involvements whereby the furcation entrance is deliberately opened and widened so that interdental brushes or similar hygiene aids can pass directly through the furcation. It is most commonly applied to mandibular molars. The procedure sacrifices the remaining periodontal attachment within the furcation in exchange for predictable plaque control. Editors should note that tunnel preparation is conceptually opposite to regenerative approaches and should not be used interchangeably with furcation plasty. Long-term success depends heavily on patient compliance with rigorous home care.
Usage
Usage note: Editors should ensure tunnel preparation is not described as a regenerative procedure; it is an intentionally destructive furcation management strategy.
