Introduction/Objective. The class II malocclusion results in disbalanced facial harmony, primarily noticeable the profile and lower third. Aside from skeletal evaluation, orthodontic diagnosis treatment planning should include soft tissue analysis. aim of study was to identify outcomes II, division 1 patients determine if these changes are related different protocols. Methods. first group non-e...
The purpose of this investigation was to assess the dentoskeletal effects and facial profile changes as well as the mechanism of Class II correction in adult Class II subjects treated by surgical mandibular advancement in combination with orthodontics. The subject material comprised 46 adults with a Class II, division 1 malocclusion treated by nonextraction with a mandibular sagittal split oste...
Skeletal, dental and soft-tissue changes induced by the Jasper Jumper appliance in late adolescence.
The purpose of this study was to evaluate the skeletal, dental, and soft-tissue changes in late-adolescent patients treated with Jasper Jumpers applied with sectional arches. The study sample consisted of 30 subjects (15 treated, 15 untreated) with skeletal and dental Class II malocclusion. Our study was carried out on 75 lateral cephalometric films. Among these radiograms, 15 were taken before...

Electromyographic (EMG) investigations about the activities of the muscles have been the focus of attention for many years. In the field of orthodontics, investigators, among other things, tried to evaluate correlation between EMG activity, occlusal relationships and craniofacial morphology to analyze the effect of muscular activity, as an etiological factor in malocclusion. The purpose of the ...
Maxillomandibular analysis relates the upper and lower jaw. The anteroposterior relationship of maxilla mandible through both angular linear measurements is used to assess sagittal jaw relationship. To evaluate skeletal maxillomandibular changes in patients with class I malocclusion after extraction non-extraction orthodontic treatment Solan population. Cephalometric radiographs before 50 were ...
BACKGROUND A treatment modality for Class II division 1 malocclusion is discussed. Orthodontic treatment of patients with deep bite and Class II malocclusion is an important challenge in clinical practice. The aim of this work is to compare the efficacy of anterior bite plane functional appliance (ABPFA) by assessing the changes in different times with untreated patients by literature. MATERI...
