Oropharyngeal Airway Volume Following Orthodontic Treatment: Premolar Extraction Versus Non-extraction
Introduction: Concern has been raised that premolar extraction reduces arch length and diminishes space for the tongue, thus forcing the tongue to be retro-positioned. There is speculation that this retro-position of the tongue reduces pharyngeal space leading to breathing problems, notably obstructive sleep apnea. There is little evidence that retracting teeth into extraction spaces changes ai...
متن کاملDimensional changes of dental arch following non-extraction orthodontic treatment
Introduction: Since the emergence of normal occlusion concept, selecting an appropriate treatment plan with or without tooth extraction has been a controversial subject. Nowadays, both methods can be successfully used for treatment of patients. However, some clinicians still believe that non-extraction orthodontic treatments have fewer complications.

متن کاملExtraction versus non-extraction: evaluation by digital subtraction radiography.
The aim of this study was to investigate the facial profile changes of patients treated with and without extractions of four first premolars using novel computer-based digital subtraction software. The pre- and post-treatment radiographic image pairs of 25 extraction (13 girls and 12 boys, mean age = 12.64 +/- 1.82 years) and 24 non-extraction (12 girls and 12 boys, mean age = 12.48 +/- 1.66 ye...

OBJECTIVE To compare changes occurring in the soft tissue profile with orthodontic treatment in extraction versus nonextraction cases, and to determine the hard and soft tissue parameters that show significant correlations to understand the factors influencing the response to tooth movement. STUDY DESIGN Quasi-experimental. PLACE AND DURATION OF STUDY Dental Section, The Aga Khan University...
متن کاملthe effects of cooperative versus individual directed reading thinking activities on students inferential and referential questions
two groups of students were assigned as experimental and control ones, and were given instruction on directed reading-thinking activities and after some treatment, they were post-tested. although the initial pre-test did not show any significant differences, the final post-test result revealed that the cooperative reading comprehension helped the experimental group. the cooperative students’...
