Abstract The purpose of this study was to use micro-computed tomography to investigate the internal structure of the zygomatic bone, and to evaluate the effects of biting force on the zygomatic bone by comparing the internal structure of this bone between dentulous and edentulous maxillae. In this study, 20 zygomatic bones of dentulous maxillae and 28 zygomatic bones of edentulous maxillae were used (mean age: dentulous maxillae, 72.6 years; edentulous maxillae, 79.6 years). Specimens were… Expand
Study on internal structure of zygomatic bone using micro-finite element analysis model--differences between dentulous and edentulous dentition in Japanese cadavers.
The muFEA modeling revealed that the angle of the trabeculae at the Jugale in edentulous jaws was lower than that in dentulous jaws, which suggests that the internal structure of trabECulae is influenced by occlusal force in zygomatic bone from edENTulous jaws. Expand
MicroCT-based evaluation of the trabecular bone quality of different implant anchorage sites for masticatory rehabilitation of the maxilla.
The trabecular compartment of the zygomatic bone offered bone quality and, thus, an implant bed comparable with those of the anterior maxilla, and both were superior to the posterior maxilla. Expand
Three-dimensional finite elemental analysis of zygomatic implants in craniofacial structures.
An integrated system for Digital Imaging and Communications in Medicine (DICOM) data were utilized to create a three-dimensional model of craniofacial structures that provided details of anatomical structures in the regions of interest. Expand
Microstructural properties of the mid-facial bones in relation to the distribution of occlusal loading.
The results suggest that the mid-facial bones in the adult dentate male skull exhibit regional variations in cortical and trabecular bone micro-architecture that could be a consequence of different occlusal stress. Expand
Morphological changes in the zygomatic arch during growth
It is suggested that the form of the zygomatic arch and theZygomaticotemporal suture showed growth change adjusting to the functional change in mastication with growth. Expand

An improved three-dimensional FE model of the human skull is developed and it is demonstrated that cortical bone has a priority in the transfer of occlusal load in the anterior maxilla, whereas both cortical and trabecular bone in the posterior maxilla are equally involved in performing this task.

Analysis of trabecular microarchitecture of human iliac bone using microcomputed tomography in patients with hip arthrosis with or without vertebral fracture.
3D analysis demonstrated that the value of the bone surface to bone volume (BS/BV) ratio could discriminate between these two groups, and that decreases in the parameters of the 3D-structure-related bone surface density as well as decreases in trabecular bone volume are related to osteoporotic fracture.

Postextraction changes in the adult mandible as illustrated by microradiographs of midsagittal sections and serial cephalometric roentgenograms
Microradiography of midsagittal sections of 21 edentulous mandibles revealed external resorption and an absence of periosteal bone on the residual ridges in all specimens, highlighting the variations in form and degree of mineralization of the various elements of bone. Expand
Quantification of Periapical Bone Destruction in Mice by Micro-computed Tomography
It is demonstrated that micro-CT imaging is a rapid, reproducible, and non-invasive method, that gives results that are closely comparable with those obtained by histology, and appears to have utility for the accurate quantification of changes in bone architecture in small biological specimens.

Morphometric analysis of human bone biopsies: a quantitative structural comparison of histological sections and micro-computed tomography.
The trabecular structure of transiliac bone biopsies was assessed by conventional histomorphometry and by three-dimensional microcomputed tomography (microCT) and results showed highly significant correlations between conventional histology and microCT, which are very promising for the use of micro-tomographic imaging.

Three-dimensional finite element analysis of the facial skeleton on simulated occlusal loading.
A 3-D finite element model of a human skull, based on CT scans, was constructed to analyse strain and stress distribution in the facial skeleton caused by simulated occlusal loading to show even distribution of strain following loading of the full maxillary arch throughout the facial elements.

Quantification of Bone Microarchitecture with the Structure Model Index.
A new morphometric parameter called Structure Model Index (SMI) is introduced, which makes it possible to quantify the characteristic form of a three-dimensionally described structure in terms of the amount of plates and rod composing the structure. Expand
Morphometric analysis of noninvasively assessed bone biopsies: comparison of high-resolution computed tomography and histologic sections.
The results from the morphometric analysis support the assumption that cancellous bone structures based on noninvasive high-resolution CT measurements are representative for trabecular microstructures assessed from histologic bone sections. Expand
