The recognition and elimination of dental compensation is essential in presurgical orthodontic treatment to achieve successful stabilization of the occlusion after surgery. However, the relationship between a transverse dental anomaly and skeletal asymmetry is not fully understood. To evaluate this relationship, frontal cephalometric and 3-dimensional(More)
Nine syndromes associated with varying patterns of abnormal physical growth were selected to study quantitative craniofacial dysmorphology with cephalometric analysis. A schematic diagram was developed in which a hexagon measures the neurocranium and facial skeletal size and form. This hexagon offers the possibility of quantitative dysmorphic(More)
OBJECTIVE The development of biomaterials for secondary bone grafting to the alveolar cleft, recombinant human morphogenetic protein-2 (rhBMP-2) may have great potential to promote osseous regeneration. The purpose of this study was to investigate the osteoinductive activity of low-dose rhBMP-2 (10 microg/100 microL) and the biological response of newly(More)
OBJECTIVE The purpose of this preliminary study was to examine experimental tooth movement into newly generated bone induced by recombinant human bone morphogenetic protein-2 (rhBMP-2). METHOD After extraction of the maxillary first premolars, bone defects were surgically created in eight adult beagle dogs using a 5-mm-diameter trepan bar. According to(More)
The purpose of this article is to describe a newly developed 3D computer-aided design (CAD) system for the diagnostic set-up of casts in orthodontic diagnosis and treatment planning, and its preliminary clinical applications. The system comprises a measuring unit which obtains 3D information from the dental model using laser scanning, and a personal(More)
OBJECTIVE The purpose of this study was to observe tooth eruption pattern into the newly generated bone induced by recombinant human bone morphogenetic protein-2 (rhBMP-2). METHOD Three 12-week-old beagle dogs were used. Following wound healing of the extracted maxillary third deciduous incisor at the age of 13 weeks, a resection of maxillary alveolar(More)
The purpose of this article is to introduce the outline of our newly developed three-dimensional dental cast analyzing system with laser scanning, and its preliminary clinical applications. The system is composed of a measuring device with a slit-ray laser projector and two sets of coupled charged devised video cameras, an image processing unit, a 16-bit(More)
P-A cephalometric analysis was performed on the craniofacial morphology in 88 Brazilian men with nonoperated and operated cleft lip and palate. For the comparative study, these subjects were divided into the following four groups: (1) 31 nonoperated unilateral cleft lip and palate (UCLP), (2) 24 nonoperated bilateral cleft lip and palate (BCLP), (3) 16(More)
OBJECTIVE Oculo-facio-cardio-dental (OFCD) syndrome is a very rare condition that requires comprehensive dental management because of associated multiple dental anomalies such as canine radiculomegaly, delayed dentition, oligodontia, persistent primary teeth, microdontia, and macrodontia. This report presents a case of OFCD in a Japanese girl (13 years 1(More)
Longitudinal dento-skeletal changes in unilateral cleft lip and palate (UCLP) patients following maxillary distraction osteogenesis using the rigid external distraction device (RED) were analyzed. Twelve Japanese non-syndromic UCLP patients who underwent maxillary distraction at the mean age of 16.4 years were used as subjects. Serial sets of lateral(More)
