PURPOSE The aims of the present study were to delineate the characteristic patterns of 3-dimensional (3D) mandibular movement in patients with skeletal Class III malocclusion compared with normal individuals and to investigate the longitudinal changes in mandible and condylar motion after orthognathic surgery (OGS). PATIENTS AND METHODS The subjects in(More)
OBJECT The authors attempt to provide a standard for volumes of the intracranial space, brain, and cerebrospinal fluid (CSF) in healthy control individuals by using in vivo three-dimensional (3D) computerized tomography (CT) data and to compare these data with those obtained from a group with Crouzon syndrome. METHODS Fifty-seven individuals underwent 3D(More)
Bilateral symmetry in vertebrates is imperfect and mild asymmetries are found in normal growth and development. However, abnormal development is often characterized by strong asymmetries. Coronal craniosynostosis, defined here as consisting of premature suture closure and a characteristic skull shape, is a complex trait. The premature fusion of the coronal(More)
BACKGROUND The purpose of this study was to quantitate preoperative osseous dysmorphology in a homogeneous group of 3-month-old infants with unilateral complete cleft lip and palate. METHODS High-resolution computed tomography scans of 28 infants with unilateral complete cleft lip and palate were the basis for study. Coordinate data from 43 landmarks on(More)
Facial asymmetry is common in humans. Significant facial asymmetry causes both functional as well as esthetic problems. When patients complain of facial asymmetry, the underlying cause should be investigated. The etiology includes congenital disorders, acquired diseases, and traumatic and developmental deformities. The causes of many cases of developmental(More)
PURPOSE The purpose of this study was to devise a method for producing customized positioning guides for translating virtual plans to actual orthognathic surgery, and evaluation of the feasibility and validity of the devised method. METHODS Patients requiring two-jaw orthognathic surgery were enrolled and consented before operation. Two types of(More)
Facial attractiveness has long been argued upon varied emphases by philosophers, artists, psychologists and biologists. A number of studies empirically investigated how facial attractiveness was influenced by 2D facial characteristics, such as symmetry, averageness and golden ratio. However, few implementations of facial beauty assessment were based on 3D(More)
PURPOSE Combining the maxillofacial cone-beam computed tomography (CBCT) model with its corresponding digital dental model enables an integrated 3-dimensional (3D) representation of skeletal structures, teeth, and occlusions. Undesired artifacts, however, introduce difficulties in the superimposition of both models. We have proposed an artifact-resistant(More)
