Summary

There's a scarcity in literature concerning en-masse retraction and its effect on the rate of tooth movement. The purpose of this study is to determine, In orthodontic patients with maxillary protrusion, which form of mechanics in en-masse retraction offers a faster rate of retraction; Friction or Frictionless Mechanics.

Conditions

  • Bimaxillary Protrusion

Interventions

PROCEDURE

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 212 g per side) extending between the crimpable hooks and the miniscrew

PROCEDURE

T- Loop

Closing retraction T-loops will be fabricated using 0.017 x 0.025 TMA wire. The loop will be positioned halfway the extraction space and the canine
