1. Understanding the basis of space closure in Orthodontics for a more efficient orthodontic treatment
RESUMO Introdução: O fechamento de espaços é um dos processos mais desafiadores na Ortodontia e requer uma compreensão sólida de conceitos biomecânicos, a fim de se evitar efeitos colaterais indesejáveis. Compreender o fundamento biomecânico do fechamento de espaços possibilita uma melhor definição das opções de ancoragem e tratamento, por par

2. Postretention stability after orthodontic closure of maxillary interincisor diastemas
Anterior spaces may interfere with smile attractiveness and compromise dentofacial harmony. They are among the most frequent reasons why patients seek orthodontic treatment. However, midline diastema is commonly cited as a malocclusion with high relapse incidence by orthodontists. Objectives: This study aimed to evaluate the stability of maxillary interinci

4. Mechanical evaluation of space closure loops in Orthodontics
This study evaluated the mechanical performance of teardrop-shaped loops and teardrop-shaped loops with helix used in orthodontic space closure. Sixty retraction loops made with 0.019" x 0.025" stainless steel (SS) and beta-titanium (BT) wires were used. They were attached to a testing machine to measure the magnitudes of the sagittal force and the load-defl

5. Reabertura dos espaços de extrações nos diferentes protocolos de tratamento ortodôntico / Extraction space reopening in different orthodontic treatment protocols
The aim of this retrospective study was to compare the frequency and quantity of reopening extraction spaces in long term of Class II malocclusion treated with two premolar extraction protocol, with those treated with four premolar extractions and Class I malocclusion cases treated with extractions of four premolars. The sample, from files of the Department

6. AVALIAÇÃO DE FORÇAS LIBERADAS POR ALÇAS EM FORMA DE GOTA UTILIZADAS EM MECÂNICA ORTODÔNTICA PARA FECHAMENTO DE ESPAÇOS / EVALUATION OF FORCES DELIVERED BY TEARDROP LOOPS USED IN ORTHODONTIC MECHANICS FOR CLOSING SPACES
O objetivo desta pesquisa foi investigar os efeitos da altura, secção transversal e tipo de liga no desempenho mecânico de alças confeccionadas em forma de gota, indicadas para a retração de incisivos e para a retração em massa de incisivos e caninos, buscando avaliar o comportamento das mesmas em relação às magnitudes de força ótima existentes

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
