Evaluation of the Anchorage Loss During En-masse Retraction in Orthodontic Patients With Maxillary Protrusion

NCT04902456 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 30

No results posted yet for this study

Summary

There is scarcity in literature regarding the effectiveness of friction and frictionless mechanics during ''En-masse retraction''technique on anchorage loss of posterior segment in orthodontic patients with maxillary protrusion. Moreover there is deficiency in studies measuring the patient pain and satisfaction regarding the different techniques of retraction.

The aim of the current study is to evaluate the effects of friction versus frictionless mechanics, implemented during "En-masse retraction", on anchorage loss. Additionally, assessment of both techniques regarding their rates, effects on root resorption as well as patient satisfaction.

Conditions

  • Bimaxillary Protrusion

Interventions

PROCEDURE

Power chain and Crimpable hook fro En-masse Retraction

Retraction will start on a 0.017x0.025" stainless steel wire using elastomeric chain ( for applied will be 212 g per side ) extending between the cripmable hooks and the miniscrew

PROCEDURE

T-loop

closing retraction T-loops will be fabricated using 0.017x0.025 TMA wire. The loop will be positioned halfway the extraction space and the canine.
