Dentoskeletal and soft-tissue changes comparison between the Jasper Jumper and Twin Force Bite Corrector in Class II malocclusion patients: A retrospective study
ConclusionThe Jasper Jumper and Twin Force associated to fixed appliances were effective in correcting Class II malocclusion with a combination of skeletal and dentoalveolar changes. However, the TF seems to provide more skeletal effects with greater maxillary growth restriction and mandibular length increase when compared to the JJ. (Source: International Orthodontics)

Comparison of force delivery of thermally activated aesthetic and non-aesthetic Ni-Ti wires: An in-vitro study
ConclusionIt is concluded that during the unloading phase at a temperature of 36 Â°C, the orthodontic archwires analyzed did not show significant difference in force between thermally activated wires with aesthetic coating and their non-aesthetic equivalents at most displacement points analysed, except for the deflection of 2.5 mm, which showed higher values.

Transverse, vertical, and anterior-posterior changes between tooth-anchored versus Dresden bone-anchored rapid maxillary expansion 6 months post-expansion: A CBCT randomized controlled clinical trial
ConclusionsT-RME and B-RME produced similar amounts of skeletal expansion. B-RME group produced a lower component of dental expansion. Due to the Dresden B-RME configuration, asymmetrical expansion was noted. (Source: International Orthodontics)

CBCT assessment of posterior cranial base and surrounding structures in orthodontically treated adolescents
ConclusionsThe studied landmarks in the posterior cranial base and surrounding area showed minor clinically insignificant changes over the study period. The observed changes could be attributed to measurement error. The posterior cranial base is deemed to be stable in all three dimensions of study during the adolescent growth period studied.

Effects of cold chemical (glutaraldehyde) versus autoclaving sterilization on the rate of coating loss of aesthetic archwires: A double-blind randomized clinical trial
ConclusionsWithin the limitations of this 1-month clinical trial limited to 4 coated NiTi archwire brands only, the average coating removal of examined brands might not differ much, amounting to about 26% within a month. Glutaraldehyde and autoclave sterilization might not affect the average speed of coating loss in all brands, although each sterilization method might be favourable for certain brands.RésuméObjectifL’effet de la stérilisation, quelque-soit la méthode (chimique à froid ou à la chaleur) sur l’élimination du film enduit sur les arcs orthodontiques esthétiques n’a pas encore été étudié.

Coated nickel titanium archwires and their uncoated counterparts: In-vitro contemporary comparison of unloading forces
ConclusionThe unloading forces demonstrated variability between the wires tested and between the different deactivations. Therefore, depending on the type of movement required and the periodontal conditions, orthodontists should pay attention during archwire selection. (Source: International Orthodontics)

Reliability of cephalograms derived of cone beam computed tomography versus lateral cephalograms to estimate cervical vertebrae maturity in a Peruvian population: A retrospective study
ConclusionCBCT is a reliable method for CVM assessment and can be used as an alternative method for this purpose. The orthodontists might use the CBCT scans as a valuable tool for CVM method estimation. (Source: International Orthodontics)

Comparison of bone thickness in infrazygomatic crest area at various miniscrew insertion angles in Dravidian population – A cone beam computed tomography study
ConclusionsThe best possible site for miniscrew insertion is 12 to 17 mm above the occlusal plane at an angle of 65° to 70°, with no injury to the adjacent anatomical structures, no mucosal irritation and adequate stability for the miniscrew. The ideal infrazygomatic crest screw length for Dravidian population is 9 to 11 mm.RésuméIntroductionLes mini-vis insérées au niveau de la crête infrazygomatique représentent une avancée importante dans le domaine de l’orthodontie en matière de renforcement d’ancrage. La taille des mini-vis et le site d’insertion dépendent de l’épaisseur osseuse de la zon...

Decalcification and bond failure rate in resin modified glass ionomer cement versus conventional composite for orthodontic bonding: A systematic review & meta-analysis
ConclusionsDue to the limited number of studies and studies with high risk of bias, no strong conclusion can be drawn. More studies need to be done to reasonably conclude that RMGIC is beneficial in reducing the occurrence of DWSLs and have comparable bond failure rate. The protocol was registered on PROSPERO (CRD42019125386) prior to the commencement of the systematic review.RésuméIntroductionLes lésions de déminéralisation de type tâche blanche (DWSLs) sont un des effets néfastes du traitement orthodontique. Le ciment verre ionomère modifié par adjonction de résine (RMGIC) a été introduit pour en réduire le ...

Comparison of anchorage loss between conventional and self-ligating brackets during canine retraction – A systematic review and meta-analysis
ConclusionThis systematic review and meta-analysis found insufficient evidence to suggest a significant difference in anchorage loss between the CB and SLB groups. The scarcity of current evidence dictates that further studies are needed to canonically establish the clinical superiority of one over the other.Review registrationPROSPERO 2019 CRD42019133217.RésuméIntroductionL’ancrage est défini comme une résistance à un mouvement dentaire indésirable. En orthodontie, une perte d’ancrage peut être un effet négatif du traitement. Les partisans des attaches autoligaturantes (SLB) prônent l’utilisation de forces ...
