<p>Methods of manufacturing orthodontic tube brackets (100) including a hole (106) rather than an open slot. A first pilot hole (218) is formed along a first axis (P1) so as to extend mesially-distally through the body (204) of the orthodontic bracket body. A second pilot hole (220) is formed along a second axis (P2), in which the second axis (P2) is offset relative to the axis (P1) of the first hole (218). The result is that the first and second holes (215, 220) are adjacent to, or may partially overlap, one another depending on the diameter of each hole (218, 220) and the dimensions of the finished rectangular arch wire hole (206). Once the pilot holes (218, 220) are formed, one or more shaping broaches are pushed or pulled through the pilot holes so as to form a desired rectangularly-shaped arch wire hole (206) within the orthodontic bracket body (204).</p> |
