There is no more exact method of manufacturing brackets than metal injection molding (MIM).
It offers smoothness for comfort and good looks, and precise tolerances for exact in-out measurements.
Notice the well-designed gingival offsets on the lower biscuspid brackets, perfectly positioned to minimize interference. The anatomically contoured 100-count mesh base maximizes the bonding power of your bracket adhesive. Plus, its biocompatible material is nickel-free.

• Low profile design with generous
  tie-wing undercuts accommodate
  both ties and chain
• Gingivally offset bicuspid tie-wings
  for less occlusal interference
• Vertical scribe line allows accurate
  long axis tooth placement
• Integral smooth, rounded hooks - at no extra charge – distal on the upper cuspid, mesial on the upper bicuspids, distal on the lower cuspids and bicuspids
• Uppers have slightly larger base for increased bonding strength
