Orthodontic bracket

Abstract

Orthodontic brackets that can accurately be mounted to the surface of teeth to effectively perform orthodontic treatment. The orthodontic bracket according to the present invention is characterized in that, a marker is provided on at least a portion of an outline that is generated by crossing a plane including a longitudinally extending center line, on a base of an archwire slot, of the archwire slot and vertical to the base of the archwire slot, and an outer surface of the body with each other. With this bracket, coinciding the marker provided on at least a portion of the outline to the mid-transverse plane of a tooth, to which the bracket is bonded, allows the base point of the bracket to be positioned on the mid-transverse plane, further, coinciding the center of the bracket to the FACC causes the bracket to accurately be positioned on the tooth to be treated, resulting in effective orthodontic treatment. The marker can be selected from a protrusion, a projection, a slit and a notch.

1 . An orthodontic bracket characterized in that, a marker is provided on at least a portion of an outline that is generated by crossing a plane including a longitudinally extending center line, on a base of an archwire slot, of said archwire slot and vertical to the base of the archwire slot, and an outer surface of the body with each other.  
   
   
       2 . The orthodontic bracket as claimed in  claim 1 , wherein said marker is selected from a protrusion, a projection, a slit and a notch.  
   
   
       3 . An orthodontic bracket characterized in that, a through hole penetrates a body from a base of said body to an outer surface of said bracket along a line passing through a point that is generated by crossing a line, which is generated by crossing a plane including a longitudinally extending center line, on a base of an archwire slot, of said archwire slot and vertical to the base of the archwire slot, and the base of the body, and a plane vertical to the center line of the archwire slot and dividing the body exactly into two parts.  
   
   
       4 . The orthodontic bracket as claimed in  claim 3 , further comprising a marker provided on at least a portion of an outline that is generated by crossing the plane including the longitudinally extending center line, on the base of the archwire slot, of the archwire slot and vertical to the base of the archwire slot, and an outer surface of the body with each other.  
   
   
       5 . The orthodontic bracket as claimed in  claim 4 , wherein said marker is selected from a protrusion, a projection, a slit and a notch.  
   
   
       6 . An orthodontic bracket characterized in that, one of a projection and a concave portion is provided at a point that is generated by crossing a line, which is generated by crossing a plane including a longitudinally extending center line, on a base of an archwire slot, of said archwire slot and vertical to the base of the archwire slot, and the base of the body, and a plane vertical to the center line of the archwire slot and dividing the body exactly into two parts.  
   
   
       7 . The orthodontic bracket as claimed in  claim 6 , further comprising a marker provided on at least a portion of an outline that is generated by crossing the plane including the longitudinally extending center line, on the base of the archwire slot, of the archwire slot and vertical to the base of the archwire slot, and an outer surface of the body with each other.  
   
   
       8 . The orthodontic bracket as claimed in  claim 7 , wherein said marker is selected from a protrusion, a projection, a slit and a notch.
