Influence of maxillary posterior dentoalveolar discrepancy on angulation of maxillary molars in individuals with skeletal open bite
BACKGROUND The aim of this study was to determine the effect of the maxillary posterior dentoalveolar discrepancy (MPDD) on the angulation of maxillary molars in open bite subjects. METHODS Pre-treatment lateral cephalograms of 90 young adults with skeletal open bite were examined. The sample initially included six groups categorized according to MPDD condition (present or absent) and sagitta...
متن کاملHyoid bone position and vertical skeletal pattern--open bite/deep bite.
UNLABELLED The Hyoid Bone (HB) is a singular bone with no articulation, but is associated with some vital functions. The purpose of this study was to test the null hypotheses that there is no change in HB position in individuals with vertical jaw dysplasia. METHODS Eleven factors were used to determine the position of the HB. In this paper the ANOVA (two way analysis of variance) method was u...
متن کاملAlveolar bone mapping in subjects with different vertical facial dimensions.
OBJECTIVE The purpose of this study was to investigate differences in alveolar and skeletal dimensions among subjects with different vertical facial dimensions using cone beam computed tomography (CBCT). To date, this is the first study that investigates the relationship between facial type and posterior alveolar thickness in both maxilla and mandible, using CBCT data. MATERIALS AND METHODS F...
متن کاملComparison of airway dimensions in skeletal Class I malocclusion subjects with different vertical facial patterns
OBJECTIVE The aim of this study was to compare upper airway widths among skeletal Class I malocclusion subjects with different vertical facial patterns. METHODS The sample included a total of 99 lateral cephalograms of post pubertal individuals (18.19 ± 1.76 years old). The vertical facial pattern was determined by the Vert index. The McNamara method was used to quantify upper airway widths. ...
متن کاملVertical changes following orthodontic extraction treatment in skeletal open bite subjects.
The purpose of this investigation was to assess the vertical changes occurring in skeletal open bite patients treated orthodontically with different extraction patterns. The study was conducted using lateral cephalometric radiographs taken before and after treatment. Fifteen patients who had an anterior open bite (AOB) only were treated with first premolar extractions (Group E4). Seventeen pati...
