Evaluation of the Rate of Anterior Segment Retraction Using Two Types of Mechanics

Bimaxillary Protrusion Clinical Trial

Official title:
Evaluation of the Rate of Anterior Segment Retraction Using Friction Versus Frictionless Mechanics: A Randomized Clinical Trial

Clinical Trial Summary

The rate of anterior segment retraction in bi-maxillary protrusion cases was evaluated comparing the friction and friction-less mechanics. since, there has been a lack of clear cut guidelines for clinicians for the optimum method for retraction, this randomized clinical trial was done.

Clinical Trial Description

Thirty bi-maxillary protrusion female patients were randomly allocated into either intervention groups. In the Friction group, retraction was accomplished using elastomeric power chains extending from crimpable hooks distal to the lateral incisors, on 0.017x0.025-inch Stainless Steel wires, to the mini-screws . While in the friction-less group with retraction done using T- loop springs made of 0.017x0.025-inch titanium molybdenum wires. Retraction force was set to 160g per side in both intervention groups. Activation was done every four weeks. Rate of anterior segment retraction was evaluated via digital models. ;
