Arch widths after extraction and nonextraction treatment in class I patients.
AIM To compare pretreatment and post-treatment dental arches in relation to intercanine and intermolar width changes in extraction and nonextraction treatment in class I patients. MATERIALS AND METHODS In this retrospective study pretreatment and post-treatment dental casts of 60 patients (30 extractions of first premolars and 30 nonextractions) were selected. Anterior and posterior arch widt...

OBJECTIVE To compare soft tissue changes in Class I borderline cases treated with extraction and nonextraction modalities. METHODS A parent sample of 150 patients with Class I dental and skeletal malocclusion (89 patients treated with premolar extraction and 61 patients without extraction) was randomly selected and subjected to discriminant analysis which identified the borderline sample of 4...
متن کاملTooth size and arch dimension in uncrowded versus crowded Class I malocclusions.
AIM The purpose of this investigation was to examine the extent to which arch dimension or tooth size contributes to dental crowding. METHODS AND MATERIALS Two groups of dental casts were selected. Each group consisted of 30 pairs of dental casts including equal male and female samples. The first group had Class I malocclusions without crowding or spacing. The second group exhibited Class I m...
متن کاملChanges in Cranial Base Morphology in Class I and Class II Division 1 Malocclusions.
INTRODUCTION The cranial base plays a key role in craniofacial growth; it helps to integrate spatially and functionally different patterns of growth in various adjoining regions of the skull such as components of the brain, the nasal and oral cavity and the pharynx. The aim of this study was to evaluate the difference in cranial base flexure between skeletal and dental Class I and Class II divi...
متن کاملTreatment changes in Class I and mild Class II malocclusions using the en masse removable appliance.
The aim of this retrospective study was to examine the dental changes which occurred during buccal segment retraction in 39 subjects considered suitable for treatment with headgear to the maxillary dentition. Initially, a removable en masse appliance was fitted to distalize the buccal segments. Once the molar relationship was corrected, fixed appliances were placed for upper arch consolidation ...
