Effectiveness of Composite Attachments in Controlling Upper-Molar Movement with Aligners
Volume 50 : Number 6 : Page 0 : Jun 2016
In nonextraction treatment, upper-molar distalization is often the method of choice to gain 2-3mm of arch space and obtain a Class I relationship. To achieve bodily movement, either the applied force must pass through the tooth’s center of resistance or a sophisticated equivalent system of forces and moments must be applied to the molar crown.

Treatment of Labially Impacted Upper Central Incisors
Volume 49 : Number 11 : Page 701 : Nov 2015
When the parents or the general dentist notices erupted upper lateral incisors and only one erupted central incisor in an 8-to-10-year-old child, it raises the possibility of an impacted upper central incisor - a significant esthetic concern. Treatment of such a patient in the mixed dentition requires an understanding of the eruption pattern of the permanent teeth. If the single central incisor had erupted six months previously, for example, or the lateral incisors had erupted before the central incisor, it would indicate a developmental problem requiring further investigation.

Forced Eruption of Multiple Impacted Teeth in an Adolescent Patient
Volume 54 : Number 8 : Page 451 : Aug 2020
A 12-year-old patient with five impacted upper anterior teeth is successfully treated with surgical exposure and orthodontic forced eruption. After space preparation and extraction of four first premolars, the impacted teeth are brought into the arch, and an impacted upper second premolar is erupted in the same way.
