OBJECTIVE To compare anchorage condition in cases in which transpalatal arch was used to enhance anchorage in both continuous and segmented arch techniques. MATERIALS AND METHODS Twenty cases that required first premolar extraction for orthodontic treatment and transpalatal arch to enhance anchorage were included in this study. Ten cases were treated using the continuous arch technique, while...

orthodontic miniscrews are widely used as temporary anchorage devices to facilitate orthodontic movements. miniscrew loosening is a common problem, which usually occurs during the first two weeks of treatment. macrodesign can affect the stability of a miniscrew by changing its diameter, length, thread pitch, thread shape, tapering angle and so on. in this study, a 3-d finite element analysis wa...

OBJECTIVES To assess the effectiveness of low-level laser therapy (LLLT) in reducing orthodontic pain after the application of orthodontic force (OF). METHODS A systematic search was conducted in the MEDLINE, EMBASE, Scopus, Cochrane Library, Web of Science, and EBSCOhost databases. The study included randomized clinical trials (RCT) which analysed the effectiveness of LLLT in reducing orthod...

This article reports on the orthodontic treatment performed on a 36-year-old female patient with skeletal and dental Class III pattern, presenting with a left unilateral posterior crossbite and mandibular asymmetry, and a relatively significant difference between maximum intercuspation (MIC) and centric relation (CR). The treatment was performed with maxillary dental expansion, mandibular denta...

This study offers help for drawing up a community health orthodontic assistance protocol, especially for the public health system. A preventive and interceptive orthodontic program is suggested through the inclusion of approaches in existing healthcare programs that may help prevent malocclusions, extending the services offered by Basic Healthcare Units to include fitting space retainer applian...

The aim of this study was to evaluate the short-term effects of orthodontic pain on the pressure pain threshold (PPT) of the masseter and anterior temporalis muscles, and on their electromyographic (EMG) activity during clenching and chewing. Orthodontic pain was induced in 14 healthy subjects (mean age 26.6, SEM 1.1) by placing orthodontic separators. The subjects were randomly assigned to an ...

OBJECTIVE To evaluate the effectiveness of interventions on accelerating orthodontic tooth movement. MATERIALS AND METHODS We searched the databases of PubMed, Embase, Science Citation Index, CENTRAL, and SIGLE from January 1990 to August 2011 for randomized or quasi-randomized controlled trials that assessed the effectiveness of interventions on accelerating orthodontic tooth movement. The p...
