ABSTRACT:
A unitary dispenser for elastomeric orthodontic devices such as ligatures and teeth separators has a circular carrier band that carries a series of the devices. A central, flat web is connected to the inner periphery of the band and extends across the middle of the dispenser to provide a centrally disposed gripping section. The web is preferably thinner than the carrier band and thus facilitates one-handed manipulation of the dispenser without visual observation. In use, the dispenser is rotated about a central axis when the web is gripped between a thumb and forefinger in order to bring each of the O-rings into a convenient position for detachment from the carrier band.
