Contextual and Individual Determinants of Anterior Open Bite in Adolescents.

Objective: Studying the broader determinants of anterior open bite (AOB) may guide more equitable policies.This study estimates the prevalence of AOB in Brazilian adolescents and its association with contextual and individual determinants.

Methodology: The data for dentofacial anomalies in 15- to 19-year-olds from the National Oral Health Survey SBBrasil 2010 were analysed (N = 4748).

Esthetic perception of facial profile changes after extraction and nonextraction Class II treatment.

This retrospective study evaluated facial profile pleasantness determined by two protocols of Class II treatment. The sample comprised facial profile silhouettes obtained retrospectively from the pretreatment (T1) and posttreatment (T2) cephalograms of 60 patients (42 males and 18 females) divided into two groups. One group of 30 patients (mean age of 12.

Treatment of Class III Malocclusion: Atypical Extraction Protocol.

The treatment of Angle Class III malocclusion is rather challenging, because the patient's growth pattern determines the success of long-term treatment. Early diagnosis and treatment are still highly discussed issues in orthodontic literature. This type of early intervention has been indicated more frequently in order to eliminate primary etiological factors and prevent an already present malocclusion from becoming severe.

Orthodontic Protocol Using Mini-Implant for Class II Treatment in Patient with Special Needs.

Improving facial and dental appearance and social interaction are the main factors for special needs (SN) patients to seek orthodontic treatment. The cooperation of SN patients and their parents is crucial for treatment success. .

Treatment effects of headgear biteplane and bionator appliances.

Introduction: The purpose of this investigation was to evaluate the dentoalveolar and skeletal cephalometric changes produced by headgear (HG) biteplane and bionator appliances in subjects with Class II Division 1 malocclusion.

Methods: The sample comprised 60 patients with Class II Division 1 malocclusion; 30 (15 boys, 15 girls; mean age, 10.02 years) were treated with the HG biteplane for a mean period of 1.

Importance of occlusion aspects in the completion of orthodontic treatment.

The purpose of this study was to address the therapeutic goals regarding the static and functional occlusion in the completion of orthodontic treatment. For such purpose, a study population comprising 20 female treated Class II malocclusion subjects with an initial mean age of 11 years underwent a two-phase treatment (orthopedics and orthodontics). The patients were diagnosed in centric relation and were treated according to the six keys for normal occlusion and functional occlusal parameters (centric relation, vertical dimension, lateral and anterior guidances, occlusal contacts and direction of forces applied on the teeth).
