INTRODUCTION The purpose of this study was to determine the accuracy and reliability of 3-dimensional craniofacial measurements obtained from cone-beam computed tomography (CBCT) scans of a dry human skull. METHODS Seventeen landmarks were identified on the skull. CBCT scans were then obtained, with 2 skull orientations during scanning. Twenty-nine(More)
BACKGROUND Posterior unilateral lingual crossbite (PUXB) is a common malocclusion in children. However, the extent to which PUXB affects the dentition and craniofacial structures in adults has not been fully defined. We investigated dental and skeletal asymmetry in adults with PUXB. METHODS We randomly selected 15 crossbite subjects (mean age, 26.2 years)(More)
INTRODUCTION We investigated mandibular dental arch form at the levels of both the clinically relevant application points of the orthodontic bracket and the underlying anatomic structure of the apical base. The correlation of both forms was evaluated and examined to determine whether the basal arch could be used to derive a standardized clinical arch form.(More)
OBJECTIVE To demonstrate the usefulness of a new imaging system for comparing the morphometric bases of children's self-perception of their facial profile with the perceptions of their mothers and treating clinicians. MATERIALS AND METHODS Rather than choosing among a series of static images, a computer imaging program was developed to elicit a range of(More)
OBJECTIVES To identify two novel three-dimensional (3D) cephalometric landmarks and create a novel three-dimensionally based anteroposterior skeletal measurement that can be compared with traditional two-dimensional (2D) cephalometric measurements in patients with Class I and Class II skeletal patterns. MATERIALS AND METHODS Full head cone-beam computed(More)
INTRODUCTION The purpose of this study was to compare the mandibular dental arch form and the mandibular basal bone arch form of patients with Class I malocclusion with those of patients with Class II Division 1 malocclusion. Our aims were to determine differences in dental and basal transverse dimensions and arch forms between the 2 groups, and to(More)
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(More)
INTRODUCTION The aim of this study was to compare the predictability of the cone-beam transverse (CBT), jugale (J-point), and transpalatal width measurement (TWM) analyses in identifying clinical crossbite. METHODS From a pool of patients with cone-beam computed tomography scans who came for orthodontic treatment, a sample of 133 patients was identified,(More)
INTRODUCTION The application of cone-beam computed tomography (CBCT) in orthodontics ushered in a new era in 3-dimensional analysis that promises to provide more comprehensive understanding of craniofacial skeletal anatomy. That promise is now being realized in multiple studies. The purposes of this study were to investigate a portion of transverse(More)
