Book Description
This book provides an insight into the latest advances in bone fracture healing and remodeling algorithm and their incorporation into patient-specific finite element models and the use of machine learning and artificial intelligence to predict the bone regeneration and osseointegration process with a certain degree of accuracy. It also examines the applications of numerical models to simulate the fracture healing process, which may prove to be advantageous in determining the optimal mechanical-based treatment or reconstruction after an accident or illness. This book is aimed at medical and dental professionals who are involved in implantology and tissue engineering such as dentists, oral and maxillofacial surgeons, orthopedic surgeons, students, and researchers.

Book Description
Master's Thesis from the year 2006 in the subject Medicine - Biomedical Engineering, grade: 1.0, Technical University of Munich (LS Statik), course: Master of Science of Computational Mechanics, 94 entries in the bibliography, language: English, abstract: The process of adaptive bone remodeling can be described mathematically and simulated in a computer model, integrated with the finite element method. The main focus of this thesis is the implementation of a bone remodeling algorithm in MATLAB and ANSYS on the basis of FEM. The strain energy density is used as mechanical stimulus. The cortical and trabecular bone are described as continuous materials with variable density. This thesis can be divided into four main parts. The first part is due to the material properties of cortical and trabecular bone. The second part is about the remodeling theory and gives an historical review of the developed numerical approaches up to now. The implementation of the remodeling algorithm in ANSYS and MATLAB as well as its validation is topic of part three. In last main part, the algorithm is applied to a 2D FE-model of a human proximal femur.

Book Description
This book creates the theoretical foundation that novices need to perform the finite element method in implant dentistry. It shows how both the implant dentist and the designer can benefit from finite element analysis. The authors explain the theory and math of the finite element method. Then, you get practical applications alongside discussions of the critical issues in using finite element analysis for dental implant design.

Book Description
Recent Nationwide Inpatient Sample (NIS) studies have shown that implant loosening remains one of the common reasons for revision in total joint replacement. In an effort to reduce loosening caused by long-term breakdown of the cement mantle, manufacturers introduced cementless technologies to provide biological fixation by hard tissue ingrowth at the bone-implant interface. One new material, porous tantalum, has had promising clinical results with well-fixed implants and relatively few reported cases of loosening. The factors that may be causing the lower incidence of aseptic loosening remain unknown. Therefore, the goal of this dissertation was to investigate the factors affecting bone fixation in porous tantalum implants through retrieval analysis and finite element (FE) modeling. Through the Implant Research Center0́9s retrieval program, the proportion of implants revised for aseptic loosening was compared between the porous tantalum implants and historical porous-coated implants. Retrieval analysis protocols were developed to assess and determine factors that affect bone ingrowth in porous tantalum hip and knee implants. Porous tantalum tibial trays were histologically analyzed to determine locations of fibrous tissue or bone ingrowth. The results showed that the amount of bone observed varied by implant type and location within each implant for retrieved porous tantalum acetabular shells, femoral stems, patellas and tibial trays. Retrieval results showed that modular tibial tray implants had higher bone ingrowth than the monoblock tibial trays. However, the bone ingrowth in the porous tantalum was lower than that observed in historical porous-coated implants. Histological analyses of tibial trays demonstrated bone ingrowth primarily in the superficial depth of the tibial trays, with fibrous tissue also present. The FE models showed that there was more favorable initial implant stability in the modular tibial tray compared to the monoblock implant. This study showed that the lower incidence of aseptic loosening did not appear to be associated with increased bone ingrowth for the retrieved porous tantalum hip and knee implants. Initial FE models showed that lower micromotion for the modular tibial tray compared the monoblock. This dissertation presents a multifaceted approach for analysis of highly porous biomaterials.

Book Description
Histomorphometric analyses were used to determine quantitatively the patterns of bony ingrowth that resulted from the placement of porous-surfaced dental implants. Twenty-one implants were placed in the mandibles of rhesus monkeys for up to 74 months by utilizing a two-stage approach. Quantitative histopathological evaluations were made using ground section microscopy. Bone remodeling and ingrowth from adjacent cortical bone and medullary trabeculae resulted in stable implant roots. Quantitative histomorphometric analyses revealed that approximately 60% of the available internal pores of the implants were occupied by bone. No fibrous connective tissue ingrowth or encapsulation was observed in the implant crypts.
