BioFunctional Implant Coating – US Patent Issued
March 10, 2018 admin Comment

Straumann has received a US patent for a bioactive coating for their implants. Their modified sandblasted and acid-etched (SLA) surface is coated with an Arg–Gly–Asp (RGD)-peptide-modified polymer (PLL-g-PEG/PEG–RGD). According to a study by Danny Buser, RGD-coated implants demonstrated significantly higher percentages of bone-to-implant contact as compared with controls at 2 weeks. The hypothesized mechanism is that the attachment of RGD peptides directed towards integrin receptors on the PEGylated surface promotes adhesion of cells of mesenchymal origin e.g. osteoblasts to the

ZiUnite ™ – Nobel`s new Zirconium Implant Surface?
March 10, 2018 admin Comment

Nobel Biocare makes mention of their new all-ceramic implant design that uses a zirconium based surface in their annual report (page 35). Clinical trials are in progress. It seems interest in Zirconium Oxide based implants is on the rise by the big companies. Definitely a trend to keep an eye on.

Nobel Biocare`s Groovy Implant Surface
March 10, 2018 admin Comment

Nobel Biocare has introduced an improvement to their Ti-Unite Surface. By placing micro grooves on the surface they claim to increase the implant stability by up to 30% thereby allowing for more rapid bone formation. This surface improvement takes a mechanical approach to increase Bone-to-Implant Contact as opposed to the chemical surface modification`s introduced by Astra (Osseospeed) and Straumann (SLAtive), their main competitors.

SLActive – New Hydrophilic Implant Surface Treatment
March 10, 2018 admin Comment

Straumann has introduced an improvement in their SLA implant surface. SLActive is based on the scientifically proven SLA® surface topography, but exhibits a fundamentally improved surface chemistry. Due to its ideal conditioning, the chemically active and hydrophilic SLActive surface significantly promotes the osseointegration process. Animal studies demonstrate that their new surface allows for accelerated bone remodelling during the entire osseointegration process.
