Ghouls in the Mortuary – A Halloween Story

The perils of living in New York go beyond the grave. The directors of seven funeral homes have been stripped of their licenses and face jail after pleading guilty to their role in what one US official called “the crime of the century” – whenever they got hold of a suitable corpse, they would tip off a team of illegal body harvesters led by Michael Mastromarino, a former oral surgeon who had lost his dentist`s license. Operating out of a

NobelDirect – Verdict delayed

Sweden`s Medical Product Agency (SMPA) has announced it will delay its final verdict on the safety of Nobel Biocare AB`s dental implant NobelDirect, which is alleged to cause bone-loss, until November. The agency cited a delay in the release of Nobel Biocare`s two-year follow-up study as being responsible. Two Swedish dentists in May 2005 alleged that the product is causing bone-loss, prompting investigations by the heathcare authority.

NanoTite – HA splutter coated titanium surface

Bicon have developed a new surface process, NanoTite™. A high-energy ion beam source aims a beam of ions at the surface of a target treated with HA. These high-energy ions eject the HA from the target/substrate and create a molecular cloud whose molecules bond with the surface of the Bicon Ti 6Al-4V ELI implant. This Ion-Beam Assisted Deposition process, which provides increased integration with the implant surface, is known as High-Energy Sputter Deposition. Using an Ion-Beam Assisted Deposition process, the

rhBMP-2 Bone Regeneration Around Implants

Ulf Wikesjö of the Medical College of Georgia has demonstrated impressive osseous regeneration around dental implants coated with recombinant human Bone Morphogenic Protein (rhBMP-2). Dr. Wikesjö is researching wound-healing and tissue regeneration with a $1.4 million grant from Nobel Biocare. In laboratory tests, rhBMP-2 applied onto implants directs endogenous stem cells to become bone-forming cells. The result was a nearly complete regeneration of lost tissue. He hopes to start clinical trials in the summer of 2006.

John Gotti`s Blade Implants

Famous mafia boss John Gotti, Dr Leonard Linkow and blade implants – all part of the history of implantology. An amazing story reported by the NY Daily News in 2002. Enjoy: Around 1988, after losing several teeth, Gotti tired of dentures and had permanent implants surgically installed and his remaining teeth capped. He visited the E. 50th St. offices of Dr. Leonard Linkow, a frank-talking New Yorker with a shock of white hair. Linkow had been famous among dentists worldwide

PEEK Customized Healing Abutment

BEGO Implant Systems GmbH & Co has designed a customizable healing abutment designed to shape the soft tissue. By customizing the PEEK blank at the chairside the emergence profile can be shaped, elliptical or even triangular, depending on the circumferential shape of the tooth that is to be replaced. It is made of a high-strength and completely biocompatible plastic abutment made of (implantable) polyether-ether-ketone (PEEK). This material is trimmed into the required shape with the handpiece at the chairside and

Anti-Microbial Implant NanoSurface

Brown University engineers have shown that both zinc and titanium oxide nanosurfaces can reduce the presence of bacteria. Discs with nanostructured surfaces had bumps that measured only .023 microns in diameter. Discs with microstructured surfaces had bumps that measured about 5 microns in diameter. Microstructured zinc oxide discs were host to 1,000 times more bacteria than the nanostructured zinc oxide discs. Similar, but less striking, results were duplicated on titanium oxide discs. The engineer`s hypothesis is that: `with the nanostructured

Zirconium One Stage Implants

Ceraroot have designed five ziconium-based one-stage implants for use in different areas of the mouth. The anatomically designed implants incorporate the abutment into the implant for a very esthetic result. An interesting video is posted on Google Video showing the use of a Ceraroot implant in an immmediate placement procedure.

NobelDirect – Analysts` Report on Bone Loss Controversy

Merrill Lynch and UBS have released stock research reports regarding Nobel Biocare`s NobelDirect implant design. Several recent studies suggest more than 3mm of bone loss in 14-55% of patients. An expert panel advising the Swedish Medical Products Agency on the safety of the NobelDirect implant has responded to a recent Nobel Biocare rebuttal letter in a critical manner. The Merrill Lynch analyst suggests a NobelDirect withdrawal may be ahead.

BioFunctional Implant Coating – US Patent Issued

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

This new approach has been certified for use in Germany, but FDA clearance for use in the United States is planned. A few animal and human based studies suggest that the bone-to-implant contact percentages (a measure

BTI Bone Expander Drills

B.T.I. has introduced a bone expander drill set. It uses a set of four wedge-shaped bone expanders to expand alveolar bone and condense bone in sites with low bone density. The rotary motion of either an implant handpiece or a torgue wrench is used to slowly expand the bone instead of using the more traditional osteotome/bone condenser/ridge spitter and surgical mallet combination.

Z1 Conic – Zirconium Collared Titanium Implant

T.B.R Group has introduced a unique ziconium collared implant. It features one-stage titanium implant with a zirconium trans-gingival emergence collar. They claim that the Zirconia enhances the fibroblast and osteoblast cell adhesion and proliferation compared to titanium, provides for lower bacterial colonization at the collar and shows evidence of creeping attachment of the gingiva to the zirconium collar.

SLActive – New Hydrophilic Implant Surface Treatment

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.
