INTRODUCTION Our goal was to verify the association between candidate polymorphisms and skeletal Class III malocclusion in a well-characterized homogeneous sample set. METHODS Thirty-five single-nucleotide polymorphisms were studied from 10 candidate loci in 54 Class III subjects and 120 controls. Skeletal Class III characteristics included ANB angle less than 0°, SNB angle greater than 83° (...

AIM The study aimed to identify quantitative and relational characteristics of bone, dental and soft tissue structures for Class III malocclusion, according to gender and age range. MATERIAL AND METHODS 60 conventional lateral cephalograms were divided into two groups according to ANB angle: the group of cases with skeletal Class III (n = 36) and a control group with skeletal Class I (n = 24)...

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...

PURPOSE This study was performed to evaluate the position of impacted mandibular third molars in different skeletal facial types among a group of Iranian patients. MATERIALS AND METHODS A total of 400 mandibular third molars in 200 subjects with different types of facial growth were radiographically investigated for their positions according to their types of facial growth on the basis of the...

Introduction: In orthodontic diagnosis and treatment planning an accurate evaluation of sagittal jaw relationship is important. To assess the antero-posterior jaw discrepancy between maxilla and mandible, numerous angular and linear measurements have been in corporate so as to reach correct diagnosis. So the purpose of this study is to compare ANB angle, Wits appraisal, Beta angle and W angle u...

Retromolar space has long been identified as a major factor in the aetiology of mandibular third molar impaction. The aims of this study were to compare mandibular third molar space between the different antero-posterior (A-P) skeletal patterns, between erupted and impacted third molars in the different A-P skeletal patterns, and to report on the status of third molar eruption/impaction among t...

OBJECTIVES This study was designed to assess the relationship between postsurgical cephalometric changes and quality of life and satisfaction after orthognathic surgery. MATERIAL AND METHODS Sample size consisted of 30 patients with class III and 25 patients with class II malocclusion treated with bilateral sagittal split osteotomy and Le Fort I osteotomy. Profile convexity, lower facial heig...

In orthodontic diagnosis and treatment planning, an accurate antero-posterior measurement of jaw relationships is critically important. Previously described angular and linear measurements can be inaccurate because of their dependency on various factors. The purpose of this study was to introduce a new cephalometric measurement, named the W angle, to assess the sagittal relationship between max...

the facial esthetics after orthodontic treatment and orthognathic surgery may be affected by the patient's natural head position. the purpose of this study was to evaluate the natural head position for the three skeletal classes of malocclusion.our sample consisted of 102 lateral cephalometric radiographs of patients aged 15 to 18 years; class i (n=32), class ii (n=40) and class iii (n=30). nin...
