1. Evaluation of the mechanical behaviour of different devices for canine retraction
OBJECTIVE: To mechanically evaluate different systems used for canine retraction. METHODS: Three different methods for partial canine retraction were evaluated: retraction with elastic chain directly attached to bracket; elastic chain connected to bracket hook and with sliding jig activated with the aid of an elastic chain attached to a mini-implant. For thi

2. Estabilidade da correção da Classe II, 1ª divisão com o aparelho Bionator de Balters associado ao aparelho fixo / Stability of the correction of the Class II, division 1 malocclusion with the Balters Bionator associated to fixed appliances
Orthopedic and orthodontic approaches, used in an associated way, are being considered an efficient therapeutic option for the treatment of the Class II, division 1 malocclusion when the patient still presents a favorable growth potential. However, changes in skeletal, dental and soft tissue relationships only can be considered satisfactory if they remain st

3. Considerações sobre o movimento ortodôntico de extrusão com finalidade protético-restauradora : relato de casos
A extrusão ortodôntica é um movimento induzido, realizado na mesma direção do movimento de erupção dentária. Ele pode ser realizado em inúmeras situações, tais como: dentes com fraturas horizontais, cuspídeas ou basais; lesão de cárie; perfurações endodônticas e reabsorções interna ou externa do terço cervical da raiz para que a reabilita

4. Effects of the use of Mandibular Protraction Appliance and Jasper Jumper in the treatment of Class II malocclusion / Efeitos do Jasper Jumper e do aparelho de protração mandibular no tratamento da má oclusão de classe II
The objective of this study was to compare the effects of the treatment of Class II malocclusion with the Mandibular Protraction Appliance (MPA) and the Jasper Jumper, associated with fixed orthodontic appliances. The sample used comprised 71 subjects, divided into three groups: Group 1, with 24 patients at a mean initial age of 12.36 years, treated with the

5. Stress distribution analysis caused by different intrusion arches on lower incisors in photoelastic model / Análise da distribuição de tensões, em modelo fotoelástico, decorrente de diferentes arcos de intrusão de incisivos inferiores
In the present study, the distribution of stresses caused by intrusion arches on lower incisors, in the anterior region of photoelastic model, was analyzed. The stresses were compared among the different arches. Additionally, stresses were also compared among the root thirds, as well as among the incisors for each arch type. The photoelastic model was constr

6. Cephalometric evaluation of dentoskeletal and soft tissue changes in young individuals with class II malocclusion treated with Distal Jet distalizers / Avaliação cefalométrica das alterações dentoesqueléticas e tegumentares em jovens com má oclusão de classe II tratados com distalizadores Distal Jet
This study evaluated the dentoskeletal and soft tissue changes promoted by the intraoral distalizer Distal Jet, by analysis of lateral cephalograms. The sample was composed of 44 patients, divided into two groups, as follows. Group 1 (study group) was composed of 22 patients, being 5 males and 17 females, with Class II malocclusion, among which 72,72% exhibi

7. Study of the effects of active and passive lacebacks in the biomechanics of the leveling phase using the MBT technique / "Estudo dos efeitos dos lacebacks ativos e passivos na biomecânica da fase de nivelamento utilizando-se a técnica MBT"
The purpose of this study was to evaluate the effects of active and passive lacebacks in the biomechanics of the leveling phase, using the MBT technique. The sample was composed of 29 Brazilian subjects (22 female and 7 male), Caucasian, with Class I malocclusion and mean age of 15 years and 5 months. The orthodontic treatment was planned with the extraction

8. Estudo comparativo, por meio de análise cefalométrica em norma lateral, dos efeitos dentoesqueléticos e tegumentares produzidos pelo aparelho extrabucal cervical e pelo aparelho de protração mandibular, associados ao aparelho fixo, no tratamento da Classe II, 1ª divisão de Angle / Comparative cephalometric study of the alterations occurring in soft and dentoskeletal tissues as a result of using the cervical headgear and the mandibular protraction appliance associated with orthodontic appliance, in the treatment of Class II, division 1 malocclusion
Dentoskeletal and soft tissues changes resulting from the use of the cervical headgear and the mandibular protraction appliance (MPA) were compared cephalometrically. The study comprised 81 individuals presenting Class II, division 1 malocclusion, divided into three groups of 27 patients each (14 males and 13 females). Group 1 (Control) - was composed by ind
