Integration accuracy of craniofacial cone-beam computed tomography images with three-dimensional facial scans according to different registration areas.

Objectives: To evaluate the integration accuracy of cone-beam computed tomography (CBCT) images with three-dimensional (3D) facial scans according to different registration areas.

Materials And Methods: Twenty-five patients (14 males and 11 females), with a mean age of 19.0 ± 11.

Radiographic study of the distribution of maxillary intraosseous vascular canal in Koreans.

Background: This study aimed to investigate the distribution and prevalence of intraosseous loop (anastomosis between posterior superior alveolar artery and infraorbital artery) in Koreans detected on computed tomography (CT) images taken prior to sinus augmentation surgery.

Methods: From the 177 patients who underwent sinus augmentation with lateral approach at Ewha Womans University Department of Implant Dentistry, 284 CT scans were evaluated. The canal height (CH), ridge height (RH), and canal height from the sinus floor (CHS) were measured on para-axial views at the first premolar, first molar, and second molar.

Reactivation of p53 by a Cytoskeletal Sensor to Control the Balance Between DNA Damage and Tumor Dissemination.

Background: Abnormal cell migration and invasion underlie metastasis, and actomyosin contractility is a key regulator of tumor invasion. The links between cancer migratory behavior and DNA damage are poorly understood.

Methods: Using 3D collagen systems to recapitulate melanoma extracellular matrix, we analyzed the relationship between the actomyosin cytoskeleton of migrating cells and DNA damage.

Maxillary posterior segmentation using an oscillating saw in Le Fort I posterior or superior movement without pterygomaxillary separation.

Purpose: Any remaining tuberosity or pterygoid plate frequently interferes with posterior or superior movement of the maxilla, if no pterygomaxillary separation is performed in low-level Le Fort I osteotomy. The objective of this report is to describe a technique for maxillary posterior segmentation using an oscillating saw in Le Fort I posterior or superior movement without pterygomaxillary separation and to present the authors' preliminary multicenter experience with this technique.

Materials And Methods: The authors retrospectively evaluated patients who underwent double-jaw surgery at 3 orthognathic surgery centers from May 2010 to December 2012.

Condylar positional changes up to 12 months after bimaxillary surgery for skeletal class III malocclusions.

Purpose: Postsurgical changes in the condylar position are of great importance to surgical stability, especially in asymmetric double-jaw surgery. The aims of this study were to evaluate positional changes of the condyle up to 12 months after surgery in patients with Class III malocclusion and to identify the factors affecting postsurgical condylar position.

Materials And Methods: The study included 33 adult patients diagnosed with skeletal Class III malocclusion who underwent bimaxillary surgery and had full cone-beam volumetric imaging (CBVI) records up to 1 year after surgery.

Volumetric changes in the upper airway after bimaxillary surgery for skeletal class III malocclusions: a case series study using 3-dimensional cone-beam computed tomography.

Purpose: Postsurgical changes of the airway have become a great point of interest and often have been reported to be a predisposing factor for obstructive sleep apnea after mandibular setback surgery. The purpose of this study was to evaluate the 3-dimensional volumetric changes in the upper airway space of patients who underwent bimaxillary surgery to correct Class III malocclusions.

Materials And Methods: This study was performed retrospectively in a group of patients who underwent bimaxillary surgery for Class III malocclusion and had full cone-beam computed tomographic (CBCT) images taken before surgery and 1 day, 3 months, and 6 months after surgery.

Determination of specific interactions between glucose ligand carrying polymer and glucose transporter type-1 (GLUT-1) using different cell types.

In order to develop a biomimetic polymer for cell recognition, poly [3-O-(4'-vinylbenzyl)-D-glucose] (PVG) and different types of glucose transport (GLUT)-carrying cells, namely, HepG2 cells (GLUT-1), 3T3-L1 fibroblast cells (GLUT-1 and GLUT-4), and MIN6 cells (GLUT-2), were tested for specific interaction. To clarify the nature of interaction between PVG and the different cell types, rhodamine-B isothiocyanate (RITC)-labeled polymers were used to prove and visualize the interactions. In this study, we found that labeled polymer strongly binds to HepG2 cells.
