Orthodontic plier-type tool
摘要:
An orthodontic plier-type tool has a pair of jaws, one of which has a step-type notch at the tip thereof and the other of which has a mating projection which engages in said step-type notch. When the pliers are used to engage an orthodontic band, or the like, the rear surface of the notch serves as a pushing surface to enable the pliers to mount the band, or the like, on a tooth without slippage relative to the pliers.
