Space Closure with Different Appointment Intervals: A Split-mouth Randomized Controlled Trial.

Background: Canine retraction has been successful with various force systems and retraction techniques. The appointment interval for force reactivation in canine retraction along the archwire is 4-8 weeks.

Aims: The aim was to evaluate the effect of different reactivation intervals on the rate of space closure.

Implant-supported canine retraction using different reactivation intervals of elastomeric chains: A CBCT-based split-mouth randomized controlled trial.

Introduction: Orthodontists attempt to maximize treatment efficiency regarding time, tooth position and adverse effects. A new approach, not yet explored, is the activation frequency.

Objective: The aim of this split-mouth randomized controlled trial was to evaluate the effect of reactivation intervals on the efficiency of tooth movement.

Comprehensive comparison of canine retraction using NiTi closed coil springs vs elastomeric chains.

Objectives: To compare canine retraction using NiTi closed coil springs vs elastomeric chains comprehensively in a split-mouth randomized controlled trial.

Materials And Methods: The canines in 64 quadrants were randomly retracted into the first premolar extraction spaces using NiTi closed coil springs or elastomeric chains, in the maxilla and mandible. The retraction force was 150 g.

Comparison of transverse changes during maxillary expansion with 4-point bone-borne and tooth-borne maxillary expanders.

Introduction: The purposes of this study were to evaluate and compare the dentoskeletal changes concurrent with 4-point bone-borne and tooth-borne rapid maxillary expanders in growing children.

Methods: The study was conducted with 20 growing girls (ages, 12 ± 0.6 years) with posterior crossbite.
