ABSTRACT:
A rounder terminal cap is fitted to the end of an orthodontic wire to reduce cheek injury from the sharp wires and is secured by a very small set screw in the cap. The set screw is tightened by a novel tool having a rotatable set screw wrench at the end of a bevel geared rotatable shaft in a elongated housing. For installation, the tool captures a cap between a slideable box or plate that secures a cap on its set screw until the cap is placed on an orthodontic wire and the set screw tightened. The slideable box is then moved to release the cap from the tool.
