A 3-Dimensional Evaluation of the Effects of Unilateral Vertical Mandibular Distraction Osteogenesis on Airway Volume Among Patients With Hemifacial Microsomia.

Objective: The aim of this study was to evaluate the volumetric airway changes using three-dimensional images following unilateral vertical mandibular distraction osteogenesis (uVMD) among patients with hemifacial microsomia (HFM).

Design: This retrospective study analyzed cone-beam computed tomography (CBCT) scans of patients with HFM at three different timepoints; pretreatment (T0), posttreatment (T1), and at least 6 months post-distraction (T2). The individuals underwent uVMD between December 2018-Januaray 2021.

Craniofacial Orthodontic Experience in CODA-Accredited Orthodontic Residency Programs.

To evaluate orthodontic care for patients with craniofacial anomalies (CFA) by identifying orthodontic residents' preparedness to treat certain conditions and willingness to receive more training in CFA. A 12-question survey was sent through the American Association of Orthodontics (AAO) organization to orthodontic residents. Questions were primarily designed to obtain information on the frequency with which they dealt with patients with CFA in their training, specific craniofacial conditions that orthodontic residents feel comfortable treating.

Bias in a blink: Shedding light on implicit attitudes toward patients with a cleft lip.

Introduction: Previous studies have shown that patients with cleft lip and/or palate may be stigmatized in society. The objective of this study was to use an implicit association test to evaluate the subconscious biases of non-health care providers and orthodontists against patients with a repaired cleft lip (CL).

Methods: Respondents participated in an implicit association test.

When convenience trumps quality of care: A population-based survey on direct to consumer orthodontics.

Introduction: Since the introduction of direct to consumer orthodontic (DTCO) products in the last decade, these products have been increasing in popularity among orthodontic patients. The purpose of the current article was to assess the populations' perception of DTCOs and to examine various factors that may influence their decision in choosing treatment with DTCO products.

Methods: A cross-sectional population-based survey was conducted in the United States.

Examining the variability of bone and soft tissue morphology in Hemifacial Microsomia: A case series of 8 patients.

Patients with Hemifacial Microsomia (HFM) exhibit highly variable skeletal and soft tissue asymmetries. The purpose of this study was to evaluate soft tissue discrepancies in patients with HFM and correlate them to the skeletal discrepancy. Eight patients were selected and studied retrospectively using 3-dimensional (3D) superimposition and color mapping of the soft and hard tissues.

A Qualitative Assessment of Bone Mineral Density in Individuals With Hemifacial Microsomia: A Cone-Beam Computed Tomography Study.

Objective: The purpose of this study is to utilize cone-beam computed tomography (CBCT) to compare the bone mineral density (BMD) on the affected versus nonaffected side, among individuals with hemifacial microsomia (HFM).

Methods: This retrospective study included 9 patients with HFM. Pretreatment CBCT volumes were imported into Invivo5 software, which was used to measure BMD through Hounsfield units (HU) in 3 regions of the mandible; inferior to the lower lateral incisors, inferior to the first molar and at the ramus inferior to the sigmoid notch.

A novel method for fabricating nasoalveolar molding appliances for infants with cleft lip and palate using 3-dimensional workflow and clear aligners.

Introduction: Nasoalveolar molding (NAM) was introduced over 20 years ago as adjunctive therapy for the correction of cleft lip and palate. In the current study, we propose a new approach using a digital workflow and 3-dimensional printing to fabricate clear aligner NAM devices.

Methods: A polyvinyl siloxane (PVS) impression of an infant with a unilateral complete cleft lip and palate (UCLP) is acquired and poured, and the stone model is scanned with an intraoral scanner.

Accuracy of Three-Dimensional Upper Airway Prediction in Orthognathic Patients Using Dolphin Three-Dimensional Software.

Background: Orthodontists and surgeons have been looking for more accurate methods to predict surgical outcomes in patients with skeletal discrepancies.

Methods: The sample consisted of 20 patients from the surgical clinic of a graduate orthodontic program who had been treated with Le Fort I maxillary movement, bilateral sagittal split osteotomy, with or without genioplasty. All patients had to have preoperative (T0) and at least 6 months postoperative (T1) cone-beam computed tomographies that were imported to Dolphin 3-dimensional (3D) software.

Comparison of the Pharyngeal Airway Volume Between Patients With Ectodermal Dysplasia and Unaffected Controls: A Cone-Beam Computed Tomography Study.

Purpose: Ectodermal dysplasias (EDs) are a diverse set of hereditary conditions in which 2 or more ectodermal structures develop abnormally. The purpose of this study was to use cone-beam computed tomography (CBCT) scans to measure the pharyngeal airway volume and minimum cross-sectional area (MC) among patients with ED and compare them with healthy controls.

Patients And Methods: The pretreatment CBCT scans of 9 individuals with ED and 61 controls were analyzed.

Psychosocial Adjustments Among Adolescents With Craniofacial Conditions and the Influence of Social Factors: A Multi-Informant Study.

Background: Previous studies have investigated psychosocial adjustments among adolescents with cleft lip and/or palate (CL/P), but our understanding of other craniofacial conditions remains limited. The objective of this study is to compare psychosocial adjustments among 3 groups of adolescents: craniofacial conditions other than cleft lip and/or palate (craniofacial anomaly [CFA]), CL/P, and controls (CON). Our secondary objective is to examine how social factors may predict the adjustments levels.

Effects of Case Western Reserve University's transverse analysis on the quality of orthodontic treatment.

Introduction: The purpose of this study was to evaluate the effect of using the transverse analysis developed at Case Western Reserve University (CWRU) in Cleveland, Ohio. The hypotheses were based on the following: (1) Does following CWRU's transverse analysis improve the orthodontic results? (2) Does following CWRU's transverse analysis minimize the active treatment duration?

Methods: A retrospective cohort research study was conducted on a randomly selected sample of 100 subjects. The sample had CWRU's analysis performed retrospectively, and the sample was divided according to whether the subjects followed what CWRU's transverse analysis would have suggested.
