pyknodysostosis is a rare bone disease that has autosomal dominant trait. it is characterized by short stature, diffuse osteosclerosis, acro-osteolysis, finger, and nail abnormalities. other features include open fontanelles and sutures, relative proptosis and obtuse mandibular gonial angle with relative mandibular prognathism. intraoral features such as dental abnormalities also have been repo...

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...

The purpose of this study was to evaluate changes in stress on the temporomandibular joint (TMJ) in 80 Japanese subjects (21 males and 59 females, mean age 23.7 years) with mandibular prognathism, with and without asymmetry after orthognathic surgery using the rigid bodies spring model (RBSM). The asymmetric group consisted of 40 subjects whose Mx-Md midline was more than 3 degrees. The remaini...

Patients with mandibular prognathism have, for a number of years, been treated by orthognathic surgery and post-surgical changes in the facial profile have been widely reported. However, little is known about the influence of gender and age on the soft tissues. The aim of this study was to investigate changes in the soft tissue profile following orthognathic surgery and to evaluate gender and a...

Objective: class II malocclusion is one of the most frequent problems in orthodontics and characterized by maxillary prognathism, mandibular retrognathism, or both. The aim this study to report case a patient with Angle Class I Skeletal growth phase treated two phases AEB orthodontic mini-implant. Case report: female patient, 9 years old, reported an accentuated projection anterior teeth. She h...

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. MATE...
