Background and purpose: Some measurements such as angles and planes drawn in lateral cephalometry have different relationships and correlation coefficients which help to distinguish different types of malocclusions. The aim of this study was to investigate the correlation between ANB, Wits, occlusal plane, and Y-axis cephalometric measurements in patients with class II malocclusion. Materials...
INTRODUCTION Anchorage control in patients with severe skeletal Class II malocclusion is a difficult problem in orthodontic treatment. In adults, treatment often requires premolar extractions and maximum anchorage. Recently, incisor retraction with miniscrew anchorage has become a new strategy for treating skeletal Class II patients. METHODS In this study, we compared treatment outcomes of pa...
OBJECTIVE This study aimed to evaluate the stability of molar relationship after non-extraction treatment of Class II malocclusion. METHODS The sample comprised 39 subjects (16 females, 23 males) with initial Class II malocclusion treated with no extractions, using fixed appliances. Mean age at the beginning of treatment was 12.94 years, at the end of treatment was 15.14 years and at post-ret...
Background and purpose: Respiratory function of patients is a major part of orthodontic diagnosis and treatment planning. It is affected by the dimensions of the pharyngeal airway. In this study, these dimensions were compared in patients with different skeletal patterns. Materials and methods: This cross-sectional descriptive-analytical study was performed studying the cephalograms of pa...
This retrospective investigation was designed to compare tooth size discrepancies among subjects with different skeletal malocclusions in an orthodontic population. The study employed the pre-treatment models of 200 patients (100 males, 100 females, aged from 14 to 20 years) selected from the records of the Orthodontic Department, Shiraz Dental School. The subjects were from four malocclusion g...
Improved facial aesthetics is one aim of orthodontic treatment. This study was designed to determine if the faces considered more beautiful in a young population exhibit the same parameters used by orthodontists to assess successful results. A panel of 34 laypeople (30 females and 4 males) evaluated a set containing one frontal, one frontal during smiling, and one profile photograph of 89 stude...
Vertical control is one of the primary objectives sought by orthodontists when treating malocclusions in hyperdivergent individuals. This investigation aimed at assessing vertical control, by cephalometric measurements, during the treatment of Angle Class II Division 1 malocclusion. Thirty cases, selected from the files of the São Leopoldo Mandic Dental Research Center, Brazil, of subjects with...
AIM To evaluate the use of Second Class Resolver (SCR), a new fixed orthopaedic appliance, for the treatment of skeletal Class II malocclusion in growing subjects. MATERIALS AND METHODS Design Retrospective analysis. Forty subjects were treated with Second Class Resolver (SCR). The mean age was 8 years at the beginning of treatment and 10 years at the end of treatment. Digital cephalometric s...
OBJECTIVES The aim of the present systematic review was to assess the effect of functional appliances on the airway dimensions in patients with skeletal Class II malocclusion. MATERIALS AND METHODS Articles were identified through a literature survey carried out through the following databases: (1) PUBMED, (2) Google Scholar, (3) The Cochrane Library, (4) Embase, (5) Lilac, and (6) Web of Sch...
