The purpose of this study was to compare the transverse dimensions of skeletal, dental, and nasal structures of a group of patients with maxillary narrowness before and after rapid maxillary expansion (RME) with an untreated control group using postero-anterior (PA) cephalometric radiographs. The material consisted of PA cephalograms of 25 children with a posterior crossbite (mean age 13 years ...

The purpose of this study was to examine the natural growth changes which occur between 22 and 33 years of age. The material consisted of two series of cephalograms of 74 females and 90 males with approximately 11 years between the two series. None of the subjects had orthodontic retainers when the first exposure was undertaken, or orthodontic treatment, or surgery during the observation period...

Aim: To evaluate sexual dimorphism in horizontal lip position in adults with different skeletal patterns. Material and Methods: The sample comprised of 120 patients (Females 18 years and above, Males 21 years and above) with no history of previous orthodontic treatment or functional jaw orthopaedic treatment. They were divided into different groups based on the ANB angle and gender. Group I and...

Computer-aided surgical simulation has greatly enhanced the efficiency and accuracy of orthognathic surgery for correction of dentofacial deformities. Virtual surgical planning (VSP) improves the efficiency of the presurgical work-up and provides an opportunity to illustrate the multidimensional correction at the dental and skeletal level. VSP provides preoperative insight into the surgical int...
