statement of the problem the aim of this study was to compare the treatment outcome of cl i malocclusion patients treated by two methods, including standard edgewise and mbt. materials and methods thirty subjects (23 boys and 7 girls) with an age range between 14‒19 years were included in each group. the patients had cl i malocclusion and were treated through non-ext strategy. pre- and post-tre...

The purpose of this study was to compare the severity of apical root resorption occurring in patients treated with a standard edgewise and a straight-wire edgewise technique, and to assess the influence of known risk factors on root resorption incident to orthodontic treatment. The sample consisted of 80 patients with Angle Class II division 1 malocclusions, treated with extraction of at least ...

STATEMENT OF PROBLEM One of the major outcomes of orthodontic treatment is the apical root resorption of teeth moved during the treatment. Identifying the possible risk factors, are necessary for every orthodontist. PURPOSE The aim of this study was to compare the rate of apical root resorption after fixed orthodontic treatment with standard edgewise and straight wire (MBT) method, and also t...

background and aims: one of the main goals of standard orthodontic treatment is having the roots of teeth adjacent to extraction sites parallel to each other. the purpose of this study was to compare standard edgewise and preadjusted straight wire (mbt) methods in achieving this goal. materials and methods: for comparing root parallelism, 228 maxillary quadrants and 225 mandibular quadrants of ...

background: the purpose of this study was to compare the occlusal peer assessment rating (par) index in class i patients treated by means of begg and edgewise methods. materials and methods: the pre- and post-treatment study models of class i patients, referred to two private clinics, treated with begg method (n = 30) and standard edgewise method (n = 30), were reviewed retrospectively using pa...
