“…As previous studies 11,12 have shown that CT images are not reliable for generating 3D models of teeth, the 3D laser scanner (Roland DGA Corporation) was used to generate the 3D model of the teeth from the maxillary stone model. The reliability of this scanner in generating 3D models was confirmed in a previous study.…”

Objectives: To assess the skeletal and dental effects of rapid maxillary expansion in a patient with unilateral cleft deformity of secondary palate and alveolus using the finite element method. Materials and Methods: A patient-specific composite skull model was developed from a patient computed tomographic scan and a surface scan of the patient's maxillary cast using MIMICS imaging analysis software. For volumetric meshing and the finite element analysis, Abaqus (6.7) was used. Results: The typical wedge-shaped opening that occurs after RME, seen in non-cleft patients, is not seen in cleft patients. A clockwise rotation of the maxilla as a result of maxillary expansion was evident. The areas of maximum stress were the intact primary palate region, inferior orbital foramen of the non-cleft and the cleft sides, and the zygomatic buttress of the cleft side. During expansion, the intact primary palate showed high stress and acted as a region of major resistance, followed by the zygomatic buttress on the cleft side. Conclusions: Clinicians should consider a need for customization of expansion therapy for cleft patients depending on the patient's age, the type of cleft present (primary or secondary palate), and the desired area of expansion (anterior or posterior).

“…The CT data are not accurate in generating the 3D models of teeth as a result of artifact. 11,12 To accurately model the teeth in this study, the maxillary impression was made and poured with dental stone. The stone model was then scanned using the 3D laser scanner (LPX 1200 Roland Laser Scanner, Roland DGA Corporation, Irvine, Calif).…”

“…The use of the sterilized computer-generated surgical guide and pencil was also cost-effective compared to currently available navigation systems (Ewers et al, 2005). We modified the use of the 3D RPM from a diagnosis-only purpose (Santler et al, 1998) to making a transfer of virtual information to the OR. It should be stressed that building a 3D RPM with 3D printers is now more affordable (less than 300 Euros for a 3D RP model) than stereolithographic models (Kozakiewicz et al, 2009).…”

“…We presented a technical approach based on the optimisation of the use of 3D RP models. 3D RP models are mainly used for diagnostic purposes (Santler et al, 1998). However, 3D RP models allow also for the transfer of 3D data from planning to the operating theatre (Kozakiewicz et al, 2009).…”

“…3D CT is able to clearly display surface structures in the actual size 17) . With the development of softwares, 3D CT data could even be used for surgical simulation 18) . For the first time, we used 2D images from 3D CT on deformity-free subjects to explore the role of lateral view of 3D CT imaging in evaluating the relative postions between the skull and jaw.…”

To creat a preliminary database in accordance with McNamara's cephalometric analysis on lateral view of 3D CT cephalometric of the population from northeast China. Lateral 3D CT scans from 98 adults with Class I normal occlusal relationship from northeast China were collected. The coordinates of landmark points including the subspinale, supramental, upper incisor, pognion etc, were measured with the Frankfort plane and a vertical straight line though the nasion being the origin of reference. Measurements were taken with respect to effective maxillary and mandibular lengths, middle anterior and anterior face heights, and lower anterior length. The data were then analyzed with the data in McNamara's cephalometric analysis. Our lateral view of 3D CT based McNamara's cephalometric data indicate that subspinale locate antierior to the vertical line, but there is no significant difference between male and female. Statistical differences exist between male and female on effective maxillary length, effective mandibular length, 1/3 height of middle face, 1/3 height of lower face and lower face length. The present study built the first preliminary data of McNamara's cephalometric analysis on lateral view of 3D CT cephalometric of the population from northeast China. These data would be a useful reference for diagnosis and treatment plan of dental facial deformities, however it will take time to accumulate a large sample to establish a representative database.
