Since the 19th century, and in every field of medicine, monozygotic twins have been studied to assess the involvement of genetic and environmental factors in phenotypic expression. The phenotype/genotype relationship remains the leading problem in contemporary biology. In dentofacial orthopedics, this relationship is of relevance in the three-dimensional approach to the face, in both diagnosis and treatment. The present study of two monozygotic twins presenting skeletal class III malocclusions which were genetic yet different is a clear illustration of the interaction of genotype and epigenetic factors with environmental influences...

Obstructive sleep apnea/hypopnea syndrome (OSAS) is still not widely diagnosed in children as its clinical signs are extremely variable. The diagnosis is based on recognition of the nocturnal and diurnal clinical symptoms of the syndrome, but above all on analysis of a sleep recording revealing abnormal respiratory phenomena. This recording makes it possible to determine an Apnea/Hypopnea Index (AHI) for each hour of sleep. The abnormality threshold is 1.5AHI/h for children and 5AHI/h for adults. The higher the index, the more severe the OSAS...

Dysfunctional deviations such as dysfunctional swallowing and chewing manifest as transverse arch discrepancies giving rise to positional asymmetry of the condyles and glenoid fossae with a more or less significant skeletal impact. This results almost inevitably in asymmetric occlusion in the sagittal dimension. Drawing on clinical cases, we will show which treatment strategies to adopt and which occlusal criteria to observe for finishing and stability.

OBJECTIVES: The purpose of this study was to locate traditionally-used landmarks in two-dimensional (2D) images and newly-suggested ones in three-dimensional (3D) images (cone-beam computer tomographies [CBCTs]) and determine possible relationships between them to categorize patients with Class II-1 malocclusion. METHODS: CBCTs from 30 patients diagnosed with Class II-1 malocclusion were obtained from the University of Alberta Graduate Orthodontic Program database...

In recent years, several surgical techniques have been proposed with the main goal of reducing the length of orthodontic treatment. Some of these techniques use a piezoelectric surgical instrument to perform alveolar bone cuts and promote localized bone turnover. One of the main limitations of these surgical techniques is that corticotomies may damage dental roots since traditional radiographic examinations do not allow the surgeon to precisely determine the length and three-dimensional position of the roots...

OBJECTIVES: The purpose of this study was to measure changes in buccolingual inclination and in thickness of maxillary and mandibular buccal and lingual bone of maxillary and mandibular molars following orthodontic treatment using edgewise mechanics. MATERIALS AND METHODS: Cone-beam computed tomography scans of 48 patients taken before and after completion of comprehensive orthodontic treatment were collected for this retrospective study. Buccolingual molar inclinations were reported as angular measurements using the long axis of the teeth and inferior border of the nasal floor and inferior border of the mandible, respectively...

BACKGROUND AND AIM: Esthetic wires are commonly used in orthodontic treatments. Surface roughness is an important factor in the friction and bacterial adhesion in these wires. Surface roughness of esthetic wires has not been assessed, except in a few recent (mostly qualitative esthetics) studies. The aim of this study was to quantitatively compare the surface roughness of 4 coated esthetic wires with that of a conventional orthodontic wire. MATERIALS AND METHODS: In this in vitro trial, 25 coated and uncoated orthodontic archwires were studied, including: NiTi Memory wire (American Orthodontics, USA) as a control group; Orthocosmetic Elastinol (Ortho Organizers, USA); Perfect (Hubit, Korea); Imagination (Gestenco, Sweden); EverWhite (American Orthodontics, USA)...

An original straightwire appliance was developed in order to easily adapt force and friction to the different stages and needs of treatment. The appliance features: (1) conventional brackets with a 0.020×0.030″ slot in the anterior area, passive self-ligating brackets with a 0.022×0.030″ slot in the lateral area, and tubes with a 0.022×0.030″ slot in the molar area; (2) archwires which adapt to the different stages of treatment and increase their section and stiffness progressively, starting with 0...

"KommonBase" is a system designed to customize the bracket base by means of an extended resin base covering the tooth. This system enables precise bracket placement and accurate fit on teeth. Moreover, KommonBase can be easily fabricated in a laboratory and bonded on each tooth using simple clinical procedures. Straight-wire treatment without wire bending was achieved in the clinical cases presented in this article using the KommonBase system for a labial fixed appliance. The application of KommonBase to the vestibular side enables efficient orthodontic treatment using simple mechanics...

Among eruption anomalies, tooth transposition is considered the most difficult to manage clinically and represent a real challenge for the clinician. Uncorrected, the results are often both functionally and esthetically unsatisfactory. Treatment of this anomaly varies from acceptance to correction and should take into account aspects, such as age, dental morphology, malocclusion, facial esthetics, stage of root development, position of root apices, and magnitude of the transposition. Acceptance of the transposition is the predominating treatment strategy in case reports in the literature...
