Smile changes after intrusion of maxillary incisors with temporary anchorage devices (TADs) or accentuated compensating curve arch wire

Conclusion: Smile improvement in the mini-implant group was mainly the result of improved smile arc, increase in outer intercommisural width, decrease in upper lip to upper incisal edge relationship, and decrease in overbite. With the use of accentuated compensating archwires, the only significant change was increase in the interlabial gap.
