INFORMATION ABOUT TITANIUM SANDBLASTING
You can find information and explanations about titanium sandblasting on this web page. Titanium is a lustrous transition metal with a silver color, low density and high strength. It is highly resistant to corrosion in sea water, aqua regia, and chlorine. The element occurs within a number of mineral deposits, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere, and it is found in almost all living things, rocks, water bodies, and soils.
Titanium can be alloyed with iron, aluminium, vanadium, and molybdenum, among other elements, to produce strong, lightweight alloys for medical prostheses, orthopedic implants, dental and endodontic instruments and files, dental implants, aerospace (jet engines, missiles, and spacecraft), military, industrial process (chemicals and petro-chemicals, desalination plants, pulp, and paper), automotive, agri-food, sporting goods, jewelry, mobile phones, and other applications.
Titanium sandblasting is made with the purpose of creating surface texture, resurfacing, surface preparation before painting and plating. Sandblasting comes to the fore especially for titanium implants and medical prostheses, in order to increase the surface roughness for achieving biocompatibility. Achievement of osseointegration as well as related to the surgical method, implant material and design, depend on also surface properties. Studies have shown the effects of surface characteristics on bony response. Morphologic methods are considered to be more effective in comparison with the physicchemical methods. Polished surfaces have poor retention in bone tissue. In contrast porous surfaces affect positively bony response and have better anchorage. Increasing the surface roughness by sandblasting increase the tensile bond strength of the adhesive resin of titanium. By increasing the roughness of the metal surface, sandblasting contributes to the formation of a mechanical bond.
Many surface modification techniques are being applied to improve the surface properties of dental implants nowadays. The common goal of all of these studies is to increase the implant surface quuality and to perform implantation with high biomechanical properties and biocompatibility. Titanium Sanding allows implants to better fit in the human body and increases biocompatibility so that ties can form.
The abrasives we recommend for Titanium sandblasting are aluminum oxide, glass bead, stainless steel shot, ceramic shot and plastic abrasive. It is emphasized that the abrasive type and dimension are equally important. Sandblasting is observed to affect the formation of the bond positively in the researches carried out. Furthermore, when sandblasting is performed on implants, the negative energy load on the implant during sandblasting is positively influenced during osteointegration.
