Official title

Evaluation of Root Resorption Following Different Mandibular Incisors Intrusive Mechanics : A Randomized Clinical Trial

Overview

Evaluation of root resorption following different mandibular incisors intrusive mechanics : A randomized clinical trial

Interventions

  • Other Mini-screw
    7 patients will receive an intrusive force delivered by elastics from 2 mini-screws between mandibular lateral incisor and mandibular canine.
  • Other Utility arch
    7 patients will receive an intrusive force delivered by intrusive utility arch.
  • Other Nitinol reverse curve wire
    7 patients will receive an intrusive force delivered by Nitinol reverse curve wire

Primary outcome measures

  • Linear amount of root resorption [Time frame: Change in Linear Root resorption at 6 months]
  • Volumetric amount of root resorption [Time frame: Change in Volumetric Root resorption at 6 months]
