Summary

Brief summary: there's a scarcity in literature concerning time needed to retract anterior segment following premolars extraction. the purpose of this study is to determine, in orthodontic patients with maxillary protrusion, which form of technique of retraction offers a faster treatment duration of retraction : en-masse or two step techniques

Detailed description

Anterior segment retraction can be done in one of two ways: through En masse or two step techniques. Both are viable options, but, ideally, the investigator wanted to retract and complete the orthodontic treatment as quickly as possible, in order to decrease the negative effects that may occur during treatment. Which of these techniques results in a decreased treatment time is still up for debate.

Conditions

• Bimaxillary Protrusion

Interventions

Type	Name	Description
PROCEDURE	En masse retraction	Retraction stated on a 0.017''x 0.025'' Stainless steel wire using elastomeric chain ( force applied 200 g per side) extending between the crimpable hooks and the mini-screw.
PROCEDURE	Two-Step retraction	Retraction of canine started on a 0.017''x0.025'' Stainless steel wire using elastomeric chain ( force applied 150 g per side) followed by anterior teeth retraction on 0.017''x0.025'' Stainless steel wire using elastomeric chain ( force applied 160 g per side) extending between crimpable hooks and the mini-screw.
