Metallic biomaterials are widely used in maxillofacial surgery. While titanium is presumed to be the gold standard, magnesium-based implants are a current topic of interest and investigation due to their biocompatible, osteoconductive and degradable properties. This study investigates the effects of poly-ε-caprolactone-coated and previtalised magnesium implants on osteointegration within murine...

Today, different implant designs exist in the market; however, there is not a clear understanding of which are the best implant design parameters to achieve mechanical optimal conditions. Therefore, the aim of this project was to investigate if the geometry of a commercial short stem hip prosthesis can be further optimized to reduce stress shielding effects and achieve better short-stemmed impl...

Finite element models developed from CT data are commonly used to evaluate the mechanical performance of the bone or the load transfer from implant to the bone. However, most analyses take no account either for the wide variation in material properties and geometry that may occur in natural tissues or the manufacturing imperfections in synthetic materials. Some authors recognized this limitatio...

Demineralized dentin matrix block (ABTB: Autogenous Tooth Bone Graft Block) is 3-D scaffold with same components and geometry with alveolar bone. ABTB is well incorporated and remodelled into cortico-cancellous bone with dental implant. The shape and volume were maintained with little marginal bone loss after average 44 months of follow-up.

context a key determinant for clinical success is the diagnosis of the bone density in a potential implant site. the percentage of bone-implant contact is related to bone density, and the axial stress contours around an implant are affected by the density of bone. evidence acquisition a number of reports have emphasized the importance of the quality of bone on the survival of dental implants. t...

BACKGROUND Although the bone's capability of dental implant osseointegration has clinically been utilised as early as in the Gallo-Roman population, the specific mechanisms for the emergence and maintenance of peri-implant bone under functional load have not been identified. Here we show that under immediate loading of specially designed dental implants with masticatory loads, osseointegration ...

AIM To reduce post treatments of kyphoplasty, as a common treatment for osteoporotic vertebrae. METHODS This study suggests a new method for treating vertebrae by setting the hexagonal porous structure instead of the rigid bone cement mass in the kyphoplasty (KP). The KP procedure was performed on the fresh ovine vertebra of the level L1. Micro finite element modeling was performed based on m...

Advanced surface modifications and materials were tested on the same implant geometry. Six types of dental implants were tested for osseointegration after 2, 4 and 8 weeks in a sheep pelvis model. Four titanium implant types were treated with newly developed surface modifications, of which two were chemically and two were pharmacologically modified. One implant was made of zirconia. A sandblast...

One of the most successful techniques in restoration of degenerated joint functions is total hip replacement. This surgical approach includes removal of diseased cartilage and bone parts, and replacement by the corresponding joint prostheses. By using metal alloys, high quality plastic and polymer materials, orthopedic surgeons can reconstruct hip fractures, or replace a painful, dysfunctional ...
