Summary

There's a scarcity in literature concerning mini-esthetics specially maxillary gingival display changes following en-masse retraction and two-step retraction. The purpose of this study is to determine, In orthodontic patients with maxillary protrusion, which technique of retraction will result in better esthetics upon smiling following en-masse retraction or two step retraction mechanics.

Conditions

  • Bimaxillary Protrusion

Interventions

PROCEDURE

En-masse retraction

Power chain and Crimpable hook for En-Masse Retraction Retraction will start on a 0.017"x0.025" Stainless steel wire using elastomeric chain (force applied will be 200 g per side) extending between the crimpable hooks and the miniscrew

PROCEDURE

Two step Retraction

Retraction of canine started on a 0.017"x0.025" Stainless steel wire using elastomeric chain (force applied will be 150 g per side)followed by anterior teeth retraction on 0.017"x0.025" Stainless steel wire using elastomeric chain (force applied will be 160 g per side) extending between the crimpable hooks and the mini-screw.
