Interface between titanium miniplate/screw and human calvaria.
This study demonstrates interfacial changes of titanium miniplate/screw with normal calvaria and nonvascularized calvarial bone graft ensued from craniectomy in a 53-year-old female. In 18 months after operation, a right parietal bone containing an L-shaped miniplate with screws, 5 mm long and 2 mm in external diameter, was harvested, fixed, and embedded in methylmetacrylate. Fifteen micrometer...
متن کاملBone enhancing effect of titanium-binding proteins isolated from bovine bone and implanted into rat calvaria with titanium scaffold.
Based on our previous finding that a chromatography with titanium beads selectively binds phosphoproteins, including caseins, phosvitin and dentin phosphoproteins, we investigated whether bone phosphoproteins also bind to titanium. Bovine bone matrix proteins were extracted with 2 M urea/PBS after demineralization. The 2 M urea extract was directly applied to the titanium chromatography column ...
متن کاملNanoscale Bonding between Human Bone and Titanium Surfaces: Osseohybridization
Until now, the chemical bonding between titanium and bone has been examined only through a few mechanical detachment tests. Therefore, in this study, a sandblasted and acid-etched titanium mini-implant was removed from a human patient after 2 months of placement in order to identify the chemical integration mechanism for nanoscale osseointegration of titanium implants. To prepare a transmission...
متن کاملBiological reaction to alumina, zirconia, titanium and polyethylene particles implanted onto murine calvaria.
Periprosthetic osteolysis is a serious problem that limits long-term survival of total hip arthroplasty. Ceramics have been introduced as a joint surface material to reduce osteolysis due to wear particles. The aim of this study is to investigate the biological reaction of ceramic particles on murine calvarial bone, in comparison with polyethylene and titanium particles. Sixty CL/BL6 mice were ...
متن کاملHuman Interface Studies for the Communication between Human and Systems
The human interface technologies and their applications for computer intelligence and human-robot communication will be presented. Speech, vision and tactile sensations will be especially subjected with the recent results of speech signal processing, human motion tracking and humanoid robotics studies. Assistive technologies for supporting handicapped and aged people will be also introduced.
