Alveolar bone changes after molar protraction in young adults with missing mandibular second premolars or first molars

Abstract

Patients with impacted third molars, third molars at an earlier stage of development, and mesially angulated third molars at pretreatment may have less alveolar bone resorption distal to the second molars following protraction. Patients with increased treatment time may have reduced alveolar bone resorption mesial to the second molars.
