Internal curvilinear distraction is successful in achieving clinically significant distraction with stable occlusion in our patient population of infants, adolescents, and adults. When distracting the mandible, the curve of the distractor, the position of the distractor, and the osteotomy site are accountable for the final result. The curved distractor can mimic part of the natural logarithmic ...

BACKGROUND Orthognathic surgery is a branch of maxillofacial surgery. It carries out the treatment of the facial skeleton asymmetries and deformities. The patients who ask for this surgery are often young people who usually refer symptoms related to dental malocclusion, difficulty eating and temporo-mandibular pain. These physical symptoms are often accompanied by psychological symptoms trigger...

The purpose of this study was to determine the effect of orthognathic surgery on psychological status. The subjects were 119 patients (38 males and 81 females, mean age 25.5±9.4 years) who underwent orthognathic surgery. They were divided into class III (84 patients), class II (20 patients), and class I (15 patients) groups according to the anteroposterior skeletal pattern, and they were also d...

The general formula in traditional orthognathic treatment has consisted of a variable length of preoperative orthodontic preparation, surgery itself, and a relatively constant period of postoperative orthodontics. Patients have usually expressed high levels of satisfaction with the esthetic and functional outcomes, especially if they were accurately informed about all aspects of their treatment...

This study used anthropometric data in the form of Farkas' proportion indices in order to quantify facial attractiveness, and to relate measured change through surgery, to clinical judgement. Standardized photographs of 15 orthognathic patients were used in album form and rated by 10 experienced clinicians: album 1 for facial attractiveness (before surgery) and album 2 for improvement in facial...

OBJECTIVE This paper describes changes in the characteristics of patients seeking orthodontic treatment over the past decade and the treatment they received, to identify any seasonal variations or trends. METHODS This single-center retrospective cohort study included all patients who presented to Seoul National University Dental Hospital for orthodontic diagnosis and treatment between January...

The stability of orthognathic surgery has been the subject of numerous publications over the last 20 years. It is now apparent that studies must pay attention to the homogeneity of the patients investigated and in particular, surgical techniques. In Part 2 of our study of 45 patients who had a uniform one-piece maxillary advancement with rigid fixation to advance the maxilla, we found that unco...

Material and methods Study type: Prospective, randomised, semi blinded trial. One hundred fifteen traditional treated orthognathic surgery cases were included based on inclusion and exclusion criteria. Pre-treatment records of the 115 cases were presented to a surgery team (surgeons, orthodontists) to generate a Surgery First protocol. The Surgery First protocols were then compared with the tru...

The temporomandibular joint has always been the practitioner's no-man's land. Who's in charge here? The general dentist, the prosthodontist, the oral surgeon, the otolaryngologist, the psychiatrist, or the orthodontist? Theories about the cause of problems are as varied as the specialties involved. Is the cause anatomic, occlusal, neuromuscular, myofascial, psychological, or multifactorial? In ...

OBJECTIVES To adequately perform orthognathic surgery procedures, it is from basic interest to understand the morphologic changes caused by orthognathic surgery. Anthropometric analyses of standardized frontal view and profile photographs could help to investigate and understand such changes. STUDY DESIGN We present a pre- to postoperative evaluation of orthognathic surgery results based on a...
