Effects of hydrofluoric acid and anodised micro and micro/nano surface implants on early osseointegration in rats

A Novel In Vitro Technique for Assessing Dental Implant Osseointegration

“…In addition to the rabbit model, other studies describe the use of larger animals for performing pull-out tests; for example, pull-out measurements have been made after placement of dental implants in mandible and maxilla of minipigs, 57 or in the femur of rats. 58 To the best of our knowledge, there are no studies published to date that have used a 3D tissue- Taken together, these data would suggest that the sand-blasted acid-etched titanium surface provides a better substrate for cell adhesion than the smoother machined surface. This probably allows cells to establish more stable contacts, which are in turn responsible for a better osseointegration, as confirmed by the higher pull-out strength observed for the sand-blasted acidetched cultivated samples.…”

Bone mesenchymal stem cell functions on the hierarchical micro/nanotopographies of the Ti-6Al-7Nb alloy

“…The polished samples were then treated by hydrofluoric acid etch and anodic oxidation using previously described methods. 13 All the samples were sterilised using irradiated cobalt-60 before use.…”

Biomedical Optics and Lasers

“…Use of ultra-short pulses is indicated as a cost-efficient method manufacturing of bio-friendly medical implant surfaces. [114] Nowadays, researches are concentrated on nano-roughness concept instead of microtexturing [115,116] due to this nano-roughness can present more attractive physical topography for attachment of different cell types selectively [117]. That laser induced biotechnology would bring the option to modify the implant surface selectively depending on the environment to be faced, like to be an attractive surface for tissue cells, while surface structure can be changed to protect microorganism adhesions.…”
