Distraction Osteogenesis Normalizes Mandibular Body-Symphysis Morphology in Infants With Robin Sequence.

Purpose: To evaluate changes in mandibular morphology in infants with Robin sequence (RS) after mandibular distraction osteogenesis (MDO) and compare the post-distraction morphology with that in infants without RS and infants with RS who had not undergone MDO.

Materials And Methods: Infants with RS treated with MDO were retrospectively evaluated over a 12-year period. All patients had pre-distraction and end-consolidation maxillofacial computed tomograms.

Defining mandibular morphology in Robin sequence: A matched case-control study.

Robin Sequence (RS) is classically defined as the triad of micrognathia, glossoptosis, and airway obstruction. While there remains significant debate over diagnostic criteria for severity, there is consensus regarding micrognathia as a defining feature of the condition. The purpose of this study was to compare mandibular morphology among infants and children with RS to infants and children without RS using maxillofacial computed tomography.

Quantitative assessment of the effectiveness of phase 1 orthodontic treatment using the American Board of Orthodontics Discrepancy Index.

Introduction: This retrospective study included a sample of 300 randomly selected patients from the archived records of Saint Louis University's graduate orthodontic clinic, St. Louis, Mo, from 1990 to 2012. The objective of this study was to quantify the changes obtained in phase 1 of orthodontic treatment and determine how much improvement, if any, has occurred before the initiation of the second phase.
