BACKGROUND Correction of deep overbite with subsequent achievement of long-term stability is difficult. The purpose of this study was to investigate the effectiveness and long-term stability of overbite correction with incisor intrusion mechanics. METHODS The treated group consisted of 25 subjects (13 female, 12 male) with deep overbite of at least 4 mm (mean overbite, 5.9 mm). The orthodonti...

The aim of this study was to investigate the differences in the maxillary and mandibular morphology related to the overbite. A total of 80 untreated subjects were divided into 4 groups with normal overbite, edge-to-edge bite, open bite, or deep bite and were compared with one another. Differences between the overbite groups and between genders were assessed by means of variance analysis and the...

INTRODUCTION The purpose of this cephalometric study was to investigate vertical dentoalveolar compensation in untreated adults with excessive (long-face) and deficient (short-face) lower anterior face heights. METHODS Vertical and sagittal base relationships, vertical dentoalveolar dimension in the anterior region of the jaws, incisor inclination, overbite, and overjet were assessed in 112 s...

This study was carried out to investigate the validity of the overbite depth indicator (ODI) and the anteroposterior dysplasia indicator (APDI), based on the cephalometric analysis of 122 Caucasians selected at random for assessment of vertical and sagittal relationships. Considering the occlusion, the sample was divided into three classifications in the sagittal component: 36 cases of neutrocc...

It has been postulated that dentoalveolar height is enlarged by a compensation mechanism in long face subjects. In this study, dentoalveolar composition was studied in 83 open bite patients. It was found that increases in overbite during treatment coincided with vertical lengthening of the symphysis, which exceeded increments in lower face height. This vertical growth coincided mainly with an i...

INTRODUCTION This study was a cephalometric evaluation of the growth changes in untreated subjects with deepbite at 4 time points during their developmental ages (from the early mixed dentition to the permanent dentition, and from the prepubertal phase to young adulthood). METHODS A sample of 29 subjects with deepbite (overbite >4.5 mm) was followed longitudinally from about 9 through about 1...

an increased overbite may be due to a skeletal or dental etiology that may influence treatment. the purpose of this study was to evaluate the skeletal and dentoalveolar features in patients with deep bite malocclusion in an iranian population and to determine the most and least effective and contributory variables causing deep bite.lateral cephalograms and study casts of normal (n=85) and deep ...

A boy, aged 10.5 years, with a Class II molar relationship and a very deep overbite, complaining of a gummy smile and anterior crowding, was treated nonextraction with a mini-implant and Twin-block and edgewise fixed appliances. Severely extruded and retroclined maxillary incisors were intruded and proclined with a nickel-titanium closed-coil spring anchored to a mini-implant and segmented wire...

Introduction: Differential diagnosis of skeletal and dental relationships is crucial for planning orthodontic treatment. Overbite depth indicator (ODI) and anteroposterior dysplasia indicator (APDI) had been introduced in the past for assessment of vertical and sagittal jaw relationships, respectively. Objective: The objectives of this study were to evaluate the reliability of ODI and APDI i...

Background: Overbite value is important in treatment of various malocclusions; the aim of this study was to investigate the relation between the overbite and facial, maxillary and mandibular dimensions. Materials and methods: The sample of this study included 80 pre-treatment digital true lateral cephalometric radiographs of Iraqi subjects aged 18-25 years, collected from the files of the subje...
