Key Points

  • This research aims to examine how miniscrew-anchored maxillary protraction therapy affects facial aesthetics and the relationship between upper incisors and nasolabial angle.
  • Applied miniscrew-anchored maxillary protraction therapy to adolescents
  • Measured changes in facial profile and nasolabial angle
  • Assessed upper incisor position before and after treatment
  • Improvement in facial profile observed by reduced concavity
  • Upper incisor movement led to a decrease in the nasolabial angle

Abstract

Miniscrew-anchored maxillary protraction improved the facial profile by reducing concavity. Upper incisor advancement was associated with a decrease in the nasolabial angle, confirming the influence of dental movement on soft tissue balance.
