Objective: The present study was undertaken to compare the pharyngeal dimensions in Angle’s Class I normal and Angle’s Class II division 1 samples, and to correlate it with the dentoskeletal parameters in both the groups. Materials and methods: The sample consists of 92 pretreatment lateral cephalogram, which were categorized into two groups, Group A and Group B, that they should present Angle’...

INTRODUCTION The mandibular arch form at the levels of both the application point of the orthodontic bracket and the basal bone in adults and children with Class I malocclusion and Class II Division 1 malocclusion was investigated. METHODS One hundred thirteen pretreatment mandibular casts were scanned to generate a 3-dimensional computer model of each cast. The casts were divided into Class ...

The aim of the study was to assess age-related changes in sagittal jaw relationship during pre-pubertal and pubertal development on the basis of angular [ANB, anteroposterior dysplasia indicator (APDI) and A-B plane angle] and linear (Wits, AF-BF, App-Bpp, and App-Pgpp) measurements. Lateral cephalograms of orthodontically untreated subjects were evaluated at 7, 9, 11, 13 and 15 years of age. C...

AIM The purpose of this study was to investigate the prevalence of myopia among a paediatric population with malocclusions. MATERIALS AND METHODS A total of 322 consecutive patients of the department of Orthodontics and Gnathology, Dental Clinic, University of L'Aquila, were enlisted for the study and 292 were selected according to the exclusion criteria. Pretreatment diagnostic data, whic...

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...

OBJECTIVES (1) To evaluate the applicability of using 3D digital models in the assessment of the magnitude of occlusal contacts by measuring occlusal contact surface areas (OCSAs) and 3D mesh points in 'contact' (OCMPs) in a sample of orthodontic patients; (2) To detect any sex differences in the magnitude of occlusal contacts in all malocclusion groups; (3) To detect inter- group differences; ...

BACKGROUND The extraction of teeth for orthodontic purpose has always been a controversial subject in the speciality. The aesthetics impact of the soft-tissue profile might play a key role in deciding on premolar extraction or non-extraction (NE) treatment, particularly in borderline patients. The purpose of this cephalometric study was to examine the soft-tissue treatment effects of Class II D...

Skeletal relationships in the sagittal plane do not always correspond with dental relationships. The aim of this study was to determine in which type of malocclusion the correlation between overjet and skeletal sagittal parameters assessed by lateral cephalogram analysis is the highest. The extent to which overjet can predict skeletal relationships in the sagittal plane was also assessed. Eight...
