ABSTRACT:
A cap assembly is provided for use on an oral ligature wire presenting ends that are twisted together. The cap assembly protects the oral tissue surrounding the twisted wire ends from abrasion, and includes a cap 22, 30, 36, 50, 60 sized for receipt over the twisted wire ends. The cap is formed of a material that is soft relative to the wire so that it defines a physical barrier between the twisted wire ends and the surrounding oral tissue. A collar is defined by or secured to the cap and is sized for receipt on the wire for retaining the cap on the wire while the wire ends are twisted and the cap is manipulated into covering relation on the wire ends.
