Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

En masse retraction

six anterior teeth are retracted by en masse technique using a crimpable hook distal to upper lateral incisor and a power chain.

Group Type EXPERIMENTAL

En masse retraction

Intervention Type PROCEDURE

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.

two step retraction

six anterior teeth are retracted by two step technique by canine retraction followed by four anterior teeth retraction using a crimpable hook distal to upper lateral incisor and a power chain.

Group Type EXPERIMENTAL

Two-Step retraction

Intervention Type PROCEDURE

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.
