background and aims. class iii malocclusions are considered as one of the most complex orthodontic problems to diagnose and treat. numerous studies have been conducted to determine the morphologic characteristics of craniofacial complex in patients with this malocclusion. the aim of this study was to determine the dentofacial characteristics of class iii malocclusion in mashhadian adults. mater...
The aim of this study was to evaluate the occurence of compensation in mesiodistal axial inclinations of canines in skeletal malocclusions patients. The sample consisted of 25 Angle Class II, division 1 malocclusion (group 1) and 19 Angle Class III malocclusion patients (group 2). After measurement of dental angulations through a method that associates plaster model photography and AutoCad soft...

AIM The aim of this study was to evaluate sexual dimorphism in nasal proportions of Class I and Class II skeletal malocclusions in adults. MATERIAL AND METHODS The sample comprised 120 patients (females 18 years and above and males 21 years and above), with no history of previous orthodontic treatment or functional jaw orthopedic treatment. They were divided into different groups based on poi...
The purpose of this study was to determine the effect of the T4K, a prefabricated functional appliance, on the transverse and anterior-height dimensions of the maxillary and mandibular dental arches. Dimensions before and after treatment were measured on the sample, then, natural growth was subtracted from the treatment effects and compared with twice the error of the method. A clinically signi...

INTRODUCTION It is generally believed that the orthodontic treatment of a patient with a Class II malocclusion and a small mandible is enhanced by good growth at puberty, so that the timing of peak mandibular growth at puberty becomes of interest. METHODS To test the belief that skeletal age, whether early, average, or late, can be used to predict the timing of maximum growth of the mandible,...
