Friction versus frictionless mechanics during maxillary en-masse retraction in adult patients with Class I bimaxillary dentoalveolar protrusion: a randomized clinical trial.

Background: Extraction space closure is a challenging phase during orthodontic treatment that affects not only the total treatment duration but also the whole treatment outcome.

Objective: To compare the efficiency of friction and frictionless mechanics during en-masse retraction of maxillary anterior teeth in adult patients with bimaxillary dentoalveolar protrusion.

Trial Design: Two-arm parallel group, single-center randomized clinical trial.

For Indirect Orthodontic Attachment Placement, Adding a Custom Composite Resin Base Is Not Beneficial: A Split-Mouth Randomized Clinical Trial.

Aim: The aim of this study was to compare the chairside time, bond failure rate, and accuracy of bonding between two orthodontic attachment indirect bonding techniques.

Methods And Materials: Two indirect bonding techniques were studied: unaltered base attachment (UA) and custom base attachment (CBA) methods. Eighty-four orthodontic attachments were bonded on six patient stone models.

Short-Term Efficacy of Presurgical Vacuum Formed Nasoalveolar Molding Aligners on Nose, Lip, and Maxillary Arch Morphology in Infants With Unilateral Cleft Lip and Palate: A Prospective Clinical Trial.

Objectives: The purpose of this study was to evaluate the short-term effect of series of preadjusted vacuum formed nasoalveolar molding VF NAM aligners on the morphology of nose, lip, and maxillary arch in infants with unilateral cleft lip and palate (UCLP).

Design: Prospective clinical trial.

Setting: Unilateral cleft lip and palate patients referred to outpatients' clinic.
