3. Comparison of two types of biomecanics for deep overbite correction
AIM: To compare two types of treatment for Class II deep overbite malocclusion assessing maxillary and mandibular arches behavior in subjects submitted to full orthodontic treatment with standard edgewise appliance and those who used straight wire appliance. METHODS: The sample consisted of 50 patients treated with full fixed appliances either with edgewise

4. Robust high-cycle fatigue stress threshold optimization under uncertain loadings
This paper proposes a strategy to achieve robust optimization of structures against high-cycle fatigue when a potentially large number of uncertain load cases are considered. The strategy is heavily based on a convexity property of some of the most commonly used high-cycle design criteria. The convexity property is rigorously proven for the Crossland fatigue

6. Dentofacial characteristics of patients with Angle Class I and Class II malocclusions
OBJECTIVE: The present study assessed some cephalometric measurements of the soft tissue profile in order to observe the behavior of facial convexity in patients with Class I, Class II division 1, and Class II division 2 malocclusions. METHODS: One hundred and thirty pre-treatment teleradiographs of Caucasian patients aged 10-16 years (mean age of 12.6 years

7. 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

8. Apreçamento da convexidade de ativos indexados ao percentual do CDI nos modelos de Vasicek e Cox-Ingersoll-Ross / Convexity pricing of assets indexed to a percentage of the CDI index in Vasicek and Cox-Ingersoll-Ross models
Devido à convexidade intrínseca dos ativos indexados ao percentual do CDI, o resultado esperado desses ativos que tenham seu risco de delta neutralizado com contratos de futuros de DI é diferente de zero. Esse resultado esperado, que chamaremos de prêmio de convexidade, deve ser incorporado ao preço do ativo em questão no momento de sua negociação, e

9. The convex relationship between performance and net flows of mutual funds in Brazil / A relação convexa entre desempenho e captação de fundos de investimento no Brasil
This paper researches the relationship between performance and net flows of mutual funds in Brazil. For this purpose, I used panel data to regress monthly net flows to risk-adjusted and not risk-adjusted performance of several terms. I study this relationship for equities and hedge funds. There is a positive and significant relationship between the net flows

12. Non-invasive 3D facial analysis and surface electromyography during functional pre-orthodontic therapy: a preliminary report
OBJECTIVES: Functional orthodontic devices can modify oral function thus permitting more adequate growth processes. The assessment of their effects should include both facial morphology and muscle function. This preliminary study investigated whether a preformed functional orthodontic device could induce variations in facial morphology and function along wit
