Download or read book Imaging based Numerical Study of Biomechanics and Bone Density Distribution in Human Alveolar Bone written by Kangning Su and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bone adapts to the changes of mechanical stimulus by bone remodeling activities. Bone remodeling results in the variation of bone density. This study presents the results of numerical simulations of biomechanics and mechanically adaptive bone remodeling in the human alveolar bone. Finite element models were built based on the micro X-ray computed tomography (micro-CT) images or clinical cone-beam computed tomography (CBCT) images. Strain in the alveolar bone under tooth loading or implant loading was calculated. Bone density distribution as a response to the mechanical stimulus was also computed. The results were in good agreement with experimentally measured strain using mechanical testing coupled with micro-CT and with the bone density distribution measured using clinical CBCT images. The models were used to predict the strain field with different implant positions. A number of numerical algorithms have been developed to model the adaptive bone remodeling under mechanical loads for orthopedic and dental applications. The parametric study examines the effects of several model parameters on the computed apparent bone density in mandible under normal chewing and biting forces. The density change rate was based on the strain energy density per unit mass. The algorithms used in this study containing an equilibrium zone (lazy zone) and saturated values of density change rate provided certain stability to result in convergence without discontinuous checkerboard patterns. The parametric study shows that when different boundary conditions were applied, the bone density distributions at convergence were very different, except in the vicinity of the applied loads. Compared with the effects of boundary conditions, the models are less sensitive to the choice of initial density values. Several models starting from different initial density values resulted in similar but not exactly the same bone density distribution at convergence. The results also show that, a higher reference value of mechanical stimulus resulted in lower average bone density at convergence. The width of equilibrium zone did not substantially affect the average density at convergence. However, with increasing width, the areas with the highest and the lowest bone density areas were all reduced. Moreover, the results of mechanically adaptive bone remodeling algorithms were compared with the information extracted from clinical images. Cone-beam computed tomography (CBCT) images of multiple patients were collected and processed to obtain the standard outline of mandible and average bone density distribution on the sagittal cross-sectional at the center of lateral incisors. Finite element models were built to compute the strain and stress in mandible under normal chewing and biting forces. Bone remodeling algorithm was carried out using strain energy density per unit bone mass as the mechanical stimulus to compute the bone density distribution at equilibrium. The computed bone density distribution exhibited close agreement with that obtained from CBCT image analysis with a coefficient of correlation of 0.87. The bite forces applied on teeth were transmitted through the tooth roots to the bone surrounding them, thus stimulated high trabecular bone density (1.6 g/cm3) near the tooth roots. The bending and torsion moments on the sagittal section of mandible resulted in lower bone density near the center (0.5 g/cm3) than those towards the edge of the section. The results add new knowledge of anatomy and biomechanics of mandibles and provide a new method to compare the results of numerical simulations of mechanically adaptive bone remodeling to in vivo data. Also, 3D finite element models were built based on micro-CT images and the results were compared with those obtained from mechanical testing coupled with micro-CT. Bone-implant mechanics is one of the factors that contribute to implant stability and success. In this work, voxel-based finite element models were built based on the micro-CT images of human cadaveric mandible specimens before and after implant placement. The elastic moduli of bone elements were assigned based on the intensity values in the micro-CT images of bone-tooth specimens before implant placement to avoid the beam hardening artifacts and to increase the connectivity and accuracy of the models. The implant positions in the models were determined by the micro-CT images of bone-implant specimens after implant placement. The computed results show that high strain appeared at the bone-implant contact locations and manifested into the supporting bone, including the buccal and lingual bone plates, which were not in direct contact with the implants. The strain concentration in the buccal bone plates was more substantial than that in the lingual bone plate, because the buccal bone plates were thinner than the lingual bone plates. The average values of maximum principal strain in the buccal and lingual regions of interest (ROI) were in good agreement with those experimentally measured using mechanical testing coupled with micro-CT and digital volume correlation. The implant positions were then virtually changed in the models by translating the implant towards the buccal or the lingual direction. The computed strain in the buccal bone decreased when the implant was virtually placed in the models away from the buccal bone plate. The strain in lingual bone also deceased when the implant was virtually moved in the model from the center of the alveolar socket towards the lingual or buccal plate. The results indicate that the distance of implant to the buccal bone plate can affect the mechanical stimuli in bone, especially in the buccal bone plate, which may subsequently affect the bone remodeling process and buccal bone resorption.

Download or read book Biomechanics written by and published by BoD – Books on Demand. This book was released on 2019-01-30 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: I have taught a variety of courses in biomechanics, introductory and advanced, at multiple universities in Canada. I have not been able to find or use an appropriate textbook for students whose background is not biomedical engineering. It should be noted that there are many outstanding books on biomechanics; however, they are usually not very introductory or the topics covered are too detailed, which makes it impossible for those audiences to make effective use of the book. The present book is an attempt to fill this gap. No previous familiarity of anatomy, biology, or physiology is expected, and in fact every chapter begins with a review of the relevant necessary background. Each chapter then highlights identification and explanation of the indispensable aspects of the associated biomechanics issues.
