Long-term effects of functional appliances in treated versus untreated patients with Class II malocclusion: A systematic review and meta-analysis.

Objective: To assess the cephalometric skeletal and soft-tissue of functional appliances in treated versus untreated Class II subjects in the long-term (primarily at the end of growth, secondarily at least 3 years after retention).

Search Methods: Unrestricted electronic search of 24 databases and additional manual searches up to March 2018.

Selection Criteria: Randomised and non-randomised controlled trials reporting on cephalometric skeletal and soft-tissue measurements of Class II patients (aged 16 years or under) treated with functional appliances, worn alone or in combination with multi-bracket therapy, compared to untreated Class II subjects.

Early diagnosed impacted maxillary canines and the morphology of the maxilla: a three-dimensional study.

Background: The aetiology of the canine displacement still remains controversial. Some authors implicated a deficiency in maxillary width as a local mechanical cause for impacted canines. The aim of the study was to examine whether there is a relationship between impacted maxillary canines, early diagnosed by using panoramic radiographs, and the morphology of the maxilla on 3D model casts.

No confidence that success rates of self-drilling and self-tapping insertion techniques of orthodontic mini-implants are similar.

Data sourcesMedline, Cochrane Central Register of Controlled Trials (CENTRAL), Embase, China National Knowledge Infrastructure (CNKI) and SIGLE.Study selectionRandomised controlled trials(RCTs), clinical controlled trials (CCTs) and cohort studies that assessed the success/failure rates of self-drilling and self-tapping mini-screws for orthodontic anchorage were considered.Data extraction and synthesisData was abstracted and assessed for quality by two reviewers independently.

Active-treatment effects of the Forsus fatigue resistant device during comprehensive Class II correction in growing patients.

Objective: To evaluate the active-treatment effects of the Forsus fatigue resistant device (Forsus) during comprehensive correction of Class II malocclusion in growing patients.

Methods: Fifty-four patients (mean age, 12.5 ± 1.

Treatment and posttreatment effects induced by the Forsus appliance: A controlled clinical study.

Objective: To evaluate treatment and posttreatment dentoskeletal effects induced by the Forsus device (FRD) in growing patients with Class II malocclusion in a retrospective controlled clinical study.

Materials And Methods: Thirty-six Class II patients (mean [SD] age 12.3 [1.

The effect of Teflon coating on the resistance to sliding of orthodontic archwires.

Teflon is an anti-adherent and aesthetic material. The aim of this study was to evaluate, in vitro, the influence of Teflon coating on the resistance to sliding (RS) of orthodontic archwires. For this purpose, Teflon-coated archwires were examined using frictional resistance tests by means of a universal testing machine and compared with conventional uncoated wires.
