Abstract

The orthodontic bracket positioning instrument is designed to engage an orthodontic bracket for precisely positioning a center of an orthodontic bracket on a center of the crown while maintaining an open visual field of the bracket and relevant structures of the tooth. The positioning instrument includes a key that is configured to mate with a receiving aperture formed in the bracket. A proximal side of the key is supported by a base that extends along a length of the key. An alignment notch is defined within a proximal side of the base to indicate the center of the bracket, as well as the horizontal axis of the bracket. A handle extends from the proximal side of the base. The handle may extend from the base at an angle to provide a clear line of sight to the base, the bracket, and supporting tooth.

Claims6

Dependent claims

A system for correcting teeth alignment, comprising:

an orthodontic bracket positioning instrument, the orthodontic bracket positioning instrument consisting of:
an elongate base having a proximal face, a distal face, a length, a width, and an alignment notch extending across the width of the proximal face;
a key projecting from the distal face of the base, the key including a rounded central portion and two diametrically opposed wings extending from opposing sides of the rounded central portion, the rounded central portion being aligned with the alignment notch of the base;
and
a handle extending at an obtuse angle from the proximal face of the base, the handle configured to be gripped by a hand of a user;
and
an orthodontic bracket having a receiving aperture with a rounded central portion at a center of the bracket and two diametrically opposed linear wings extending from opposing sides of the rounded central portion, the wings being aligned with a vertical axis of the bracket,
an archwire slot extending in a mesial-distal direction across the bracket and being disposed between the linear wings of the bracket,
wherein the key of the positioning instrument fits within the receiving aperture of the bracket and the alignment notch is configured to be in alignment a horizontal axis of the bracket once the bracket is mated with the key and a length of the base is oriented to align with a vertical axis of the bracket.
