“…Despite the small sample of only three patients, the upcoming results from the FEA simulations of the patient specific implants are at least as good as the results for the standard implants. Nevertheless, the measured surface roughness of the manufactured implants might be too high for suitable osseointegration [11,12]. The dimensional accuracy is marginal, which means that in this cases finishing is necessary to grant the fitting of abutments and screws to the implant.…”

Aim of this study was to prove the possibility of manufacturing patient specific root analogue twopart (implant and abutment) implants by direct metal laser sintering. The two-part implant design enables covered healing of the implant. Therefore, CT-scans of three patients are used for reverse engineering of the implants, abutments and crowns. Patient specific implants are manufactured and measured concerning dimensional accuracy and surface roughness. Impacts of occlusal forces are simulated via FEA and compared to those of standard implants.

“…Numerous reports have demonstrated that implants with micron-scale topography enable rapid and increased bone accrual or bone implant contact [21][22][23][24][25][26][27]. There are several processes that can be used to achieve implant surfaces with micro-scale topography.…”

Argon ion beam polishing technique was applied to prepare the cross sections of implants feasible for high resolution scanning electron microscope investigation. The interfacial microstructure between newly formed bone and implants with three modified surfaces retrieved after in vivo test using three different animal models was characterized. By this approach it has become possible to directly observe early bone formation, the increase of bone density, and the evolution of bone structure. The two bone growth mechanisms, distant osteogenesis and contact osteogenesis, can also be distinguished. These direct observations give, at microscopic level, a better view of osseointegration and expound the functional mechanisms of various implant surfaces for osseointegration.

Bone fracture due to an accident, aging or diseases is a feature of everyday life. One of the principal methods of repair and reconstruction of such a fracture is based on drilling the bone and fixing its separate parts together using screws, wires and plates. Morphology of the drilled hole surface and fixative components such as screws, pins and hooks influences strength of the bonds between them. Modern measurement methods provide researchers with a high-precision data on the main parameters of surface roughness. This study is concerned with measurements of surface roughness of holes drilled in a cortical bone using two drilling techniques. Hole's surface roughness produced with conventional drilling (CD) and ultrasonically assisted drilling (UAD) was measured with, and compared for, various contact and non-contact methods. The difference in surface roughness for both drilling techniques was explained based on high-speed filming of the bone drilling processes.
