Bracket positioning

Orthodontists strive for accurate bracket positioning because it makes achieving a superior occlusion easier. Whether one uses a direct or an indirect bonding technique, the initial appliance placement typically includes some bracket-positioning errors. The clinician either corrects these errors during treatment or tediously repeats archwire bends to compensate for the …
