Orthodontic bracket and clip release tool

An orthodontic bracket comprising:

• a base firmly attachable directly or indirectly to teeth surfaces;
• a bracket main body equipped on one side of the base;
• an arch wire slot shaped in groove along mesiodistal direction in the bracket main body, enabling to support an arch wire therein;
• a substantially belt-like clip curved substantially in U-shape as covering at least one part of an opposite side to the base in the arch wire slot, the clip having a catching end portion for creeping under a cover portion supported by the bracket main body at an upper end part thereof and a catching cutout portion substantially in V-shape for catching a clip release tool for releasing the clip at the upper end part thereof;
• and
• a guide portion formed in at least one of the bracket main body and the base and along a tooth axial direction crossing with the arch wire slot, enabling to guide the clip.

A clip release tool for releasing a clip from a bracket main body of an orthodontic bracket, the orthodontic bracket comprising a base firmly attachable directly or indirectly to teeth surfaces, a bracket main body equipped on one side of the base, an arch wire slot shaped in groove along mesiodistal direction in the bracket main body, enabling to support an arch wire therein, a substantially belt-like clip curved substantially in U-shape as covering at least one part of an opposite side to the base in the arch wire slot, the clip having a catching end portion for creeping under a cover portion supported by the bracket main body at an upper end part thereof and a recess portion or a substantially V-shaped catching cutout portion for catching a clip release tool for releasing the clip at the upper end part thereof, and a guide portion formed in at least one of the bracket main body and the base, and along a tooth axial direction crossing with the arch wire slot, enabling to guide the clip, the clip release tool comprising:

• a first projection and a second projection which are arranged substantially in V-shape,
• wherein the first projection enables to catch the recess portion or the substantially V-shaped catching cutout portion of the clip, and the second projection regulates the engagement of the first projection with the recess portion or the catching cutout portion, while pressing down the clip to prevent the clip from deformation of the clip.
