Stress shielding at the bone-implant interface: influence of surface roughness and of the bone-implant contact ratio [PDF]
, 2020 Short and long-term stabilities of cementless implants are strongly determined by the interfacial load transfer between implants and bone tissue. Stress-shielding effects arise from shear stresses due to the difference of material properties between bone and the implant.

Influence of implant surfaces on osseointegration [PDF]
Brazilian Dental Journal, 2010 The biological fixation between the dental implant surfaces and jaw bones should be considered a prerequisite for the long-term success of implant-supported prostheses. In this context, the implant surface modifications gained an important and decisive place in implant research over the last years.

Frontiers in Bioengineering and Biotechnology, 2022 The percutaneous osseointegrated (OI) prostheses have greatly improved the overall quality of life for amputees. However, the long-term maintenance of the OI prostheses is still challenging. A major problem is bone resorption around the bone-implant-skin interface, which might cause implant loosening or osteomyelitis. Another problem is the breakage of

Small, Volume 19, Issue 2, January 11, 2023., 2023 Fluidic force microscopy and atomic force microscopy are used to investigate the interaction of preosteoblast cells with patterned surfaces having different pillar heights. The results reveal differences in cell adhesion strength, settling state, cytoskeleton reorganization and local elastic modulus between the cells adhered on the two different ...
