ResumoIntrodução: O sono é um importante indicador de saúde e sua qualidade pode sofrer influência de diversos fatores, como alterações psicológicas e sociais; ambiente; uso de medicamentos; ingestão alcoólica e a prática regular de atividade física. Porém, ainda não está esclarecido se a atividade física teria efeito positivo sobre os distúrbios de sono mais prevalentes como insônia e apneia do sono. Objetivo: buscar publicações que falam da interação sono e atividade física, e estudos que esclareçam os efeitos da atividade física sobre a qualidade do sono e qualidade de vida. Material e Método: foi feito uma busca na literatura nas bases de dados: Biblioteca Virtual em Saúde (BVS), Scielo, Pubmed e Scopus usando os descritores Exercício; Sono; Qualidade de Vida; Apneia Obstrutiva do Sono. Resultados: foram discutidos sete artigos que abordam o assunto a atividade física como coadjuvante para a qualidade do sono mostrando que atividade física tem ação benéfica. Conclusão: a atividade física melhora a percepção subjetiva e objetiva da qualidade do sono e qualidade de vida, podendo ser utilizada como tratamento terapêutico nos tratamentos dos distúrbios do sono. Descritores: Exercício; Sono; Qualidade de Vida; Apneia Obstrutiva do Sono. AbstractIntroduction: sleep is an important indicator for health, its quality may suffer influences of several factors as psychological and social disturbances, alcohol abuse, environment, drug intake, and, positively, physical activity. However, it is not clear if physical activity would have a positive effect for the most prevalent sleep disorders as insomnia, and sleep apnea. Objective: the aim of this study was to perform a review on the literature which discussed the interaction between sleep and physical activity, regarding the repercussion on sleep quality and quality of life. Material an method: the search strategy included the databases Biblioteca Virtual em Saúde (BVS), Scielo, PubMed and Scopus, using the descriptors: Exercise; Sleep; Quality of Life; Sleep Apnea, Obstructive. Results: seven articles met the inclusion criteria, discussing physical activity as a co-adjuvant treatment, all showing improvement of sleep quality and positive effects on quality of life. Conclusion: physical activity improves subjective perception and objective evaluations of sleep quality and quality of life, and should be considered as a co-adjuvant treatment for sleep disorders.

The IBB can be suggested as a valid clinical procedure since the clinical session was faster and the total time spent for laboratorial positioning of the brackets and clinical procedure was similar to that of DBB. In addition, both approaches resulted in similar frequency of loose brackets.

Objective: To investigate the effects of the standard (Class II) Balters bionator in growing patients with Class II malocclusion with mandibular retrusion by using morphometrics (thin-plate spline [TPS] analysis). Materials and Methods: Thirty-one Class II patients (17 male and 14 female) were treated with the Balters bionator (bionator group). Mean age at the start of treatment (T0) was 10.3 years, while it was 13 years at the end of treatment (T1). Mean treatment time was 2 years and 2 months. The control group consisted of 22 subjects (14 male and 8 female) with untreated Class II malocclusion. Mean age at T0 was 10.2 years, while it was 12.2 years at T1. The observation period lasted 2 years on average. TPS analysis evaluated statistical (permutation tests) differences in the craniofacial shape and size between the bionator and control groups. Results: Through TPS analysis (deformation grids) the bionator group showed significant shape changes in the mandible that could be described as a mandibular forward and downward displacement. The control group showed no statistically significant differences in the correction of Class II malocclusion. Conclusions: Bionator appliance is able to induce significant mandibular shape changes that lead to the correction of Class II dentoskeletal disharmony. (Angle Orthod. 2013;83:455-459.)

Functional appliances induced mandible's significant posterior morphogenetic rotation over the short term. The treated and control groups demonstrated similar mandibular shape over the long term.

Objective: To evaluate the long-term effects of the standard (Class II) Balters bionator in growing patients with Class II malocclusion with mandibular retrusion by using morphometrics (thin-plate spline [TPS] analysis). Materials and Methods: Twenty-three Class II patients (8 male, 15 female) were treated consecutively with the Balters bionator (bionator group). The sample was evaluated at T0, start of treatment; T1, end of bionator therapy; and T2, long-term observation (including fixed appliances). Mean age at the start of treatment was 10 years 2 months (T0); at posttreatment, 12 years 3 months (T1); and at long-term follow-up, 18 years 2 months (T2). The control group consisted of 22 subjects (11 male, 11 female) with untreated Class II malocclusion. Lateral cephalograms were analyzed at the three time points for all groups. TPS analysis evaluated statistical differences (permutation tests) in the craniofacial shape and size between the bionator and control groups. Results: TPS analysis showed that treatment with the bionator is able to produce favorable mandibular shape changes (forward and downward displacement) that contribute significantly to the correction of the Class II dentoskeletal imbalance. These results are maintained at a long-term observation after completion of growth. The control group showed no statistically significant differences in the correction of Class II malocclusion. Conclusions: This study suggests that bionator treatment of Class II malocclusion produces favorable results over the long term with a combination of skeletal and dentoalveolar shape changes.
