No results posted yet for this study

Summary

Thirty-eight patients requiring extraction of maxillary first premolars will participate in the study. They will be divided randomly into two groups: an en-masse retraction group and a two-step group. In each group, anterior teeth retraction will be initiated after completion of the leveling and alignment phase via closed nickel-titanium coil springs applying 150 g of force per side, Mini-implants will be used as an anchor unit in the en-masse retraction group, and TPA in the two-step's retraction group.

The levels of pain, discomfort, and functional impairments will be self-reported using a validated questionnaire with a 4-points Likert scale.

Conditions

  • Class II Malocclusion

Interventions

DEVICE

Mini-implants

En masse retraction of upper anterior teeth will be applied where mini-implants will be used as an anchor unit. Anterior teeth retraction will be initiated after completion of the leveling and alignment phase via closed nickel-titanium coil springs applying 150 g of force per side.

DEVICE

Transpalatal arche (TPA)

Two-step retraction of upper anterior teeth will be applied where transpalatal arches (TPAs) will be used as an anchor unit. Teeth retraction will be initiated after completion of the leveling and alignment phase via closed nickel-titanium coil springs applying 150 g of force per side.
