Unilateral posterior crossbite often involves only one tooth, especially upper first molar; in these cases it is never easy to obtain an asymmetrical movement of a molar and a proper planning of the orthodontic device with its anchorage is necessary to avoid arch overexpansion. Thanks to its simplicity and efficacy, the modified Quad Helix here described represents a valid therapeutic tool in c...

This case report describes the orthodontic treatment of an adult patient, who presented a Angle Class II, Division 2, malocclusion, with overbite, severe curve of Spee, right maxillary lateral incisor proclined and gengival recessions. The patient was treated with extraction of the first premolars and maximum anchorage control. This case was presented to the Brazilian Board of Orthodontics and ...

Adult treatment is often hindered by the psychological, periodontal, articular and/or muscular context. Denture is often incomplete, and malocclusion is more varied. Analysis of orthodontic mechanics is thus essential to reduce unwanted displacements and achieve treatment objectives. Mini-screws are often very useful here, ensuring rigid anchorage and enhancing treatment efficacy. Benefit is di...

In routine orthodontics practice anchorage is a critical factors that determining the success of an orthodontic treatment. For many years’ has been strenuous factor. Many modalities have tried for preventing loss by using extra oral and intraoral devices according to various scientific literature, yet orthodontists did not find any convenient solutions solve this problem until mini- implants we...

BACKGROUND The Herbst appliance is an orthodontic appliance that is used for the correction of class II malocclusion with skeletal discrepancies. Research has shown that this is effective. However, a potential harm is excessive protrusion of the lower front teeth. This is associated with gingival recession, loss of tooth support, and root resorption. This trial evaluates a method of reducing th...

The aim of this retrospective study was to determine differences between the outcomes of treatment using implant anchorage compared with straight-pull headgear and intermaxillary elastics in bimaxillary protrusion patients. The lateral cephalograms of 28 adult orthodontic patients (3 males and 25 females; age, 24.9 ± 5.0 years) who had an Angle Class I malocclusion with bimaxillary protrusion w...

T dental implants are synonymous with osseointegration. The concept of osseointegration and its clinical application have positively impacted dentistry and revolutionized the ability to reconstruct the dentition and the craniofacial complex. The ability of the surgeon to precisely place bone-anchoring devices to support prostheses via osseointegration has markedly influenced the approach to rec...

Recently, new strategies for treating class III malocclusions have appeared. Skeletal anchorage appears to reduce the dentoalveolar effects while maximising the orthopaedic effect in growing patients. The purpose of this systematic review and meta-analysis is to examine the effectiveness of bone anchorage devices for interceptive treatment of skeletal class III malocclusions. Searches were made...
