This review of fixed functional appliances for the treatment of class II malocclusions could only find 11 small studies with methodological problems to assess the effectiveness of this approach. Some benefit was noted but larger higher quality studies are needed.

Treatment of posterior crossbite was rated in the top 10 most important orthodontic reviews by an international panel of oral health professionals as part of a Cochrane Oral Health Group prioritisation exercise. This new update to this Cochrane review found some evidence to suggest that the quad-helix (fixed) appliance may be more successful than removable expansion plates at correcting posterior crossbites. However, it is mainly low to very low quality.

The aim of this review was to assess the effectiveness, efficiency, and potential side effects of the various archwires used during fixed appliance orthodontic treatment. Searches were conducted in Medline, Cochrane Library, Biomed Central, BBO including LILACS, Ind Med, Sceilo, Clinical trials.gov, Conference paper Index, Digital Dissertations, German National Library of Medicine (ZB MED), Google [read the full story…]
Pain and discomfort is often reported by patients undergoing orthodontic treatment and has been cited as a reason for failure to complete treatment. Removal of fixed appliances could be painful and it has been suggested that an intrusive bite force may stabilize teeth allowing greater resistance of torsional forces. The aim of this study was [read the full story…]
Failure to maintain good oral hygiene during fixed appliance orthodontic treatment can lead to the development of demineralised white lesions (DWLs) around the orthodontic brackets. The incidence of this adverse effect of treatment has bee reported as being between 15-85. A recent Cochrane review by Benson et al (see Dental Elf 27th Jan 2014) found [read the full story…]
The development of early, but reversible, carious lesions or demineralised white lesions (DWLs) is one adverse effect of fixed appliance orthodontic treatment. The prevalence has been reported to be as high 70%, and although the majority are minor and fade with time as they resolve about 10% cavity and may require filings. The main aim [read the full story…]
Fixed banded orthodontic treatment is commonplace not only amongst children by but increasingly in adults. Being able to successful bond these brackets to the teeth during treatment is a one factor for successful treatment. The aim of this review was to compare the effects of different dental etchants and different etching techniques for the bonding [read the full story…]
Moving the upper molars backwards during orthodontic treatment is sometimes necessary. Appliances used for this are categorized in to intraoral or extraoral appliances. External headgear is one of the commonest distalising approaches. The aim of this Cochrane review was to assess the effects of orthodontic treatment for distalising upper first molars in children and adolescents. [read the full story…]
This is the latest update of a Cochrane review which aims to assess the effects of initial arch wires for alignment of teeth with fixed orthodontic braces in relation to alignment speed, root resorption and pain intensity. The Cochrane Oral Health Group’s Trials Register, CENTRAL, Medline and Embase databases were searched. Handsearching of a number [read the full story…]
