Cell behaviour on bioactive polymeric coatings

Italian Journal of Anatomy and Embryology, 2010
Researchers are testing different treatments to induce modifications in both chemical composition and topography of implant surface, with the aim to ameliorate bone­to­implant contacts and hence improve osseointegration processes and biomechanical properties in the short and long term.

Oxide thin films as bioactive coatings

Journal of Physics: Condensed Matter, 2018
Abstract Growth and survival of biological cells (eukaryotes and prokaryotes) on artificial environments often depend on their interactions with the specific surface. Various organic materials can be coated on substrates to assist cells’ adhesion and other subsequent cellular processes.

Adhesion of new bioactive glass coating

Journal of Biomedical Materials Research, 1999
A valuable alternative to the existing biomedical implant coatings is a bioactive glass (BAG) coating that is produced by reactive plasma spraying. A mechanical performance requirement that is of the utmost importance is the adhesion strength of the coating.

Coatings on Al2O3 by bioactive glass-ceramics

Acta Materialia, 2000
Abstract Pure full-density alumina substrates were coated by a bioactive glass-ceramic belonging to the system SiO 2 -Al 2 O 3 -P 2 O 5 -Na 2 O-K 2 O-CaO-F − . Through a careful optimization of the coating process, we obtained coatings approximately 200 microns thick.

Bioactive Ceramic Coatings

2015
Some kinds of metals, such as titanium and its alloys, bond directly to living bone without fibrous tissue. One of the key techniques for enhancing bone-forming ability of the metallic biomaterials is to modify their surface using bioactive ceramics. This chapter introduces various coatings on the metals to give high bioactivity, which is to have an ...

Bioactive-Coated Implants in Trauma Surgery

European Journal of Trauma and Emergency Surgery, 2007
Complications still occur in musculoskeletal surgery despite improvements in operating techniques and optimization of implants. Problems include delayed fracture healing, non-unions and extensive osseous infections. Growth factors for local application are in clinical use, but have not become widely accepted.

Bioactivity of sol-gel bioactive glass coated alumina implants

Journal of Biomedical Materials Research, 2000
Alumina on alumina total hip arthroplasty has been in use for more than 25 years with encouraging results. However, an improvement of the alumina/bone interface still is required. The objective of this study was to investigate the in vitro and in vivo osteoconductive properties of sol-gel bioactive glass coated alumina implants.

Silicophosphate glasses as a component of bioactive coatings

Proceedings. The 8th Russian-Korean International Symposium on Science and Technology, 2004. KORUS 2004., 2002
The possibility of making the hydroxyapatite-based coatings on the titanium with the use of Na/sub 2/O-SiO/sub 2/-P/sub 2/O/sub 5/ type of glasses has been investigated. The coatings ceramic phase, predominantly consisting of hydroxyapatite, was obtained from reagents and natural bones.

Nanocrystalline bioactive apatite coatings

Solid State Sciences, 2006
Abstract A study of carbonatehydroxyapatite coatings deposited by a sol–gel technique from different precursor-sols containing different water/ethanol content is performed. All the sols form uniform and homogeneous coatings with good adhesive strength values.
