Tool for orthodontic appliance
An orthodontic tool for an orthodontic appliance includes a handle and at least one distal end having a finger. The finger has a manipulator, which may include a pin or a plurality of pins, and a probe for engaging a rotary archwire cover. Using the tool, the orthodontist may open and close the archwire cover, which is rotationally mounted to an orthodontic bracket.
1. In combination, an orthodontic appliance adapted to be affixed to the surface of a patient's tooth, said appliance having an archwire slot for receiving an archwire and having a rotary cover mounted for rotation about an axial pin between an open position exposing the archwire slot and a closed position covering the archwire slot, the axial pin being oriented perpendicular to the surface of the tooth, and a tool for opening and closing said cover, said tool having a substantially straight handle having a longitudinal axis and manipulator members at a distal end for engaging said cover wherein said cover includes concave indented side portions and said manipulator members include pins that engage said concave indented side portions, whereby the handle is aligned with said axial pin when said manipulator members are in engagement with said cover, whereby said cover is opened and closed by twisting said tool about its longitudinal axis.
2. The combination of claim 1 wherein said manipulator members include a central probe which engages a depression in said axial pin.
3. In combination, an orthodontic appliance adapted to be applied to the surface of a tooth and a manipulating tool for said appliance,
(a) said orthodontic appliance comprising a base and a body portion, said body portion having an archwire slot, and a rotary cover selectively rotatable on an axis substantially perpendicular to said tooth to cover and expose said archwire slot, said cover having concave indentations on sides of the cover facing opposing directions;
(b) said manipulating tool having an elongate handle and a distal end having a finger, the finger including a pair of side by side pins adapted to engage said concave indentations simultaneously.
