Comparison of anterior mandibular alveolar thickness and height in young adults with different sagittal and vertical skeletal relationships: A CBCT Study
ConclusionsThe sagittal skeletal relationship showed no influence on the alveolar thickness or height, even if dental compensation was present. Hyperdivergent individuals showed smaller alveolar thicknesses and heights than hypodivergent individuals.RésuméObjectifL’os alvéolaire entourant les incisives mandibulaires donne les limites dans l’inclinaison buccolinguale pouvant être atteintes avec un traitement. L’objectif de cette étude était d’évaluer l’épaisseur et la hauteur alvéolaires antérieures mandibulaires chez des sujets présentant différentes relations squelettiques sagittales et verticales.Ma...

Comparison of cold-hardening bending and direct electric resistance heat treatment on the mechanical properties and transformation temperature of NiTi archwire: An in vitro study
ConclusionsNiTi archwire shape can be modified by using both cold-hardening and DERHT bending methods, because the mechanical properties and Af temperature are not affected. However, the bending distance has an effect on the mechanical properties.RésuméObjectifLe but de cette investigation était (1) de comparer les effets des méthodes d’écrouissage au froid et avec traitement thermique par résistance électrique (DERHT) ; et (2) de comparer les effets des offsets et des angulations sur les propriétés mécaniques et d’analyser les propriétés thermiques de l’arc en alliage NiTi.MéthodesLes arcs Nickel-titan...

Do orthodontic patients develop more gingival recession in anterior teeth compared to untreated individuals? A systematic review of controlled studies
ConclusionAlthough the amount of recession does not differ, some increase in the risk for gingival recession development in the anterior teeth may be encountered in orthodontically-treated individuals compared to untreated subjects with normal occlusion. However, these findings should be viewed cautiously until more studies of high quality become available. Good practice would suggest that it is important to identify patients at potential risk and consider the possible implications for orthodontic treatment.RésuméObjectifÉtudier par la preuve les données actuellement disponibles sur le développement des récessions gi...

Orthodontic-Orthognathic Management of a patient with skeletal class II with bimaxillary protrusion, complicated by vertical maxillary excess: A multi-faceted case report of difficult treatment management issues
Publication date: Available online 23 October 2019Source: International OrthodonticsAuthor(s): Rawan Oueis, Peter D. Waite, Jue Wang, Chung H. KauSummaryThis case reports the unsuccessful first treatment and the subsequent retreatment of a 35-year old Asian female with a skeletal class II with bimaxillary protrusion, complicated by a deep bite and vertical maxillary excess. This case report highlights the multiple facets of a challenging treatment plan and discusses the ramifications of treatment when treatment does not go as planned. The initial treatment plan consisted of a surgical approach with a maxillary Le Fort I su...

In vitro bleaching effect of hydrogen peroxide with different time of exposition and concentration on shear bond strength of orthodontic brackets to human enamel: A meta-analysis of in vitro studies
ConclusionBleaching with hydrogen peroxide decreases the SBS of brackets in patients undergoing orthodontic treatment especially if the time interval between bleaching and bonding procedures is short and a high concentration of hydrogen peroxide is used.RésuméIntroductionL’effet du blanchiment sur l’adhérence (SBS) des attaches orthodontiques collées à l’émail fait l’objet de controverses. L’objectif de cette étude était de faire une revue et une méta-analyse sur l’effet du blanchiment au peroxyde d’hydrogène sur la SBS selon l’intervalle entre le blanchiment et le collage sur l’émail humain et...

Assessment of microcracks and shear bond strength after debonding orthodontic ceramic brackets on enamel priorly etched by different Er,Cr:YSGG and Er:YAG laser settings without acid application: An in vitro study
ConclusionsWhen considering reduction of enamel microcrack formation and clinical acceptable shear bond strength, none of the groups succeeded both. Etching by Er:YAG (60 mJ) and Er,Cr:YSGG (1.5 W/15 Hz), showed the least overall microcrack incidence between groups, but Er:YAG (60 mJ) displayed significant reduction compared to phosphoric acid. However, etching by Er:YAG (80 mJ) had the most predictable results in term of shear bond strength.RésuméDonnées contextuellesL’incidence de craquelure amélaire est élevée après la dépose mécanique d’attaches céramiques. Cela peut être dû à ...

Optimization of clinically applied orthodontic archwire electrothermal treatment conditions by heat tint and mechanical properties: An experimental study
ConclusionHeat treatment of stainless steel orthodontic archwires using an electric resistance device is an effective and convenient method to improve their flexural modulus. The colour of the wire surface after heat treatment can help determine the heating conditions, and the maximum flexural modulus of the stainless steel wires was obtained when the colour changed to brownish yellow.RésuméObjectifLe traitement thermique par résistance électrique est utilisé est réalisé par la plupart des orthodontistes ; cependant, les effets du traitement électrothermique sur les propriétés mécaniques, la morphologie de surf...

Mini implants osseointegration, molar intrusion and root resorption in Sinclair minipigs
ConclusionIn minipigs immediate loading of smooth mini implants promoted a high degree of intrusive movement particularly of the second premolars, stimulated bone growth and osseointegration, but extensive root resorption was not observed.RésuméObjectifL’utilisation de mini-implants pour créer un point d’ancrage intrabuccal passif a été principalement testée dans des essais cliniques. Dans cette étude, une approche intégrée expérimentale a évalué les protocoles de mise en charge des mini-implants (mise en charge immédiate et mise en charge différée) sur le remodelage osseux et la stabilité des mini-impl...

A comparison between RMGIC and composite with acid-etch preparation or hypochlorite on the adhesion of a premolar metal bracket by testing SBS and ARI: In vitro study
ConclusionsRMGIC bonding with V-prep preparation is recommended for palatal/lingual surfaces and for hard-to-dry surfaces. For vestibular surfaces, studies are still needed to recommend bonding with RMGIC instead of composite.RésuméObjectifUn produit de collage peut être accepté en orthodontie quand sa capacité d’adhérence est supérieure à 5,9 MPa. Le but de notre étude est de comparer le collage d’une attache orthodontique métallique « in vitro » avec différents types de préparation de surface de l’émail sain et deux produits de collage: le composite et le ciment au verre ionomère modifié par...

Complications in orthognathic surgery: A retrospective study of 5025 cases
DiscussionComplications in orthognathic surgery are rare. While many are manageable, some could have adverse outcomes. Each complication has its own treatment. Prevention can be achieved with perfect surgical techniques. However, some complications cannot be avoided even with skilled surgeons.RésuméIntroductionLa chirurgie orthognathique est une chirurgie réglée qui a vu ses indications s’élargir grâce à la fiabilité de ses techniques et à la collaboration renforcée entre orthodontistes et chirurgiens maxillo-faciaux. Toutefois bien que rares, des complications de ces chirurgies existent. Elles peuvent, dans ce...
