Manhattan Scientifics has announced that its NanoTitanium product has been approved by the FDA. The patented new form of titanium metal originally developed by Russian scientists in concert with scientists at the Los Alamos National Laboratory is expected to significantly improve dental implants. Studies have shown that bone integrates with these new metals up to 20 times faster than with conventional metals. Patients should experience shorter post surgery healing times and a more reliable integration of these new implants into their body. NanoTitanium is highly compatible with bone and is thought to provide stronger, faster bonding with improved strength, biocompatibility, longer life and improved wear and tear. Founded in 2001, Metallicum (recently acquired by Manhattan Scientifics) has developed methods to modify the microstructure of metals by “nanostructuring” them. This procedure simultaneously increases the biocompatibility and strength of virtually any metal. For example, nanostructuring pure titanium (the material that is most commonly used in dental implants) can more than double its strength, making it stronger than most existing titanium alloys. The ability of bone cells to attach to nanostructured pure titanium surfaces at rates greater than 100% higher than with conventional alloys enables the development and marketing of a dental implant that can be fully integrated and useable with half the healing time of existing products.

Brookhaven Science Associates, the company that operates and manages the U.S. Department of Energy’s Brookhaven National Laboratory (BNL), and Biosurface Engineering Technologies, Inc. (BioSET), have been issued a U.S. patent on a synthetic peptide, called B2A. B2A enhances the effects of a tissue growth factor known as bone morphogenetic protein 2, or BMP-2. BMPs are a family of proteins in the human body responsible for the proliferation, repair and differentiation of cells in many tissues, including bone. Tom Rouche, BioSET President and CEO said “We have developed a novel combination medical device, called AMPLEX, that incorporates B2A osteo-inductive growth factor with an ultra-high grade ceramic bone substitute for use in this type of surgery. Preclinical studies have found that it is a safe and highly effective.”

This interesting article about `Titanium uses in Industry` reveals some facts you may not have known about your favorite metal:

• It has an extremely low response to magnetism
• Its use in medicine also encompasses surgical instruments and those used in image-guided surgery and magnetic resonance imagery.
• It is the ninth most plentiful element present in the Earths crust. It has been found in meteorites and detected in the sun and class M stars.
• The Apollo 17 moon mission brought back rocks containing Titanium compounds.
• Russia made an attempt to corner the market in Titanium to deprive the US and its allies of the material.
• Many more fun facts in the article

Scientists at Oregon State University have found a gene involved in enamel production. In the latest research, published in Proceedings of the National Academy of Sciences, a team led by Chrissa Kioussi and Mark Leid bred mice that lacked a gene known as Ctip2. The gene, called Ctip2, is a "transcription factor" that was already known to have several functions - in immune response, and the development of skin and the nervous system. Scientists can now add tooth development to that list. The discovery was made after researchers noticed that mice born without the gene grew teeth lacking enamel. By understanding the genetics of tooth development, Kioussi said it may be possible to repair damaged enamel and even produce new teeth in the laboratory. Paul Sharpe, an expert on tooth development at the Dental Institute at King`s College London, said: "If you could find some way of growing ameloblasts that make enamel, you could find a way to repair teeth. "Any gene like this is worth understanding. The more we learn about it the more we can use the information to make biological models of tooth repair."

Swiss implant manufacturer, Thommen Medical, have developed a new implant packaging system which allows chairside surface conditioning of their implant. The applicator makes effective chairside surface conditioning fast and intuitive. In a matter of seconds, the conditioning agent contained in the applicator hydroxylates the implant surface to achieve the super-hydrophilic INICELL surface. During the chairside conditioning with APLIQUIQ the surface chemistry is slightly modified by hydroxylation. The result of this process is increased surface energy and improved wettability. The superhydrophilic INICELL surface exhibits a water contact angle of less than 5 degrees. A hydrophilic surface, by comparison, is generally considered to have a contact angle of 90 degrees or less. These properties of the INICELL surface promote spontaneous and complete wetting with physiological fluids, particularly blood.

Université de Montréal Researchers have modified metal surfaces such as titanium producing a sponge-like pattern of nano pits that increased growth of bone cells, decreased growth of unwanted cells and stimulated stem cells, relative to untreated smooth ones. In addition, expression of genes required for cell adhesion and growth were increased in contact with the nanoporous surfaces. “We demonstrated that some cells stick better to these surfaces than they do to the traditional smooth ones,” says Dr. Nanci. “This is already an improvement to the standard available biomaterial.” “Using chemical modification, we have produced metals with intelligent surfaces that positively interact with cells and help control the biological healing response. These will be the building-blocks of new and improved metal implants that are expected to significantly affect the success of orthopedic, dental and cardiovascular prostheses.”

SinusTech America have released a sinus lift kit that features a unique reamer design that cuts, lifts and elevates the floor of the sinus with minimal danger of damage. They claim that the technique minimizes the possibility of damage to the sinus membrane, forms an appropriate sized osteotomy site for implant placement and allows for the placement of bone grafting materials into the elevated sinus cavity.

A study in the November issue of the Journal of Endodontics claims that dental implants require much more follow-up treatment than root canals, according to a study by researchers at the University of Alabama at Birmingham. Their study results reported that the success rate for the dental implants was 98.4 percent; for root canals it was 99.3 percent. However, 12.4 percent of the dental implants required additional interventions, compared with 1.4 percent of the root canals. “Considering these results in light of the growing body of evidence on the impact of oral health on overall health, it is imperative for dental professionals to partner with endodontists who have advanced training in examining whether a natural tooth can be saved through root canal treatment,” said Dr. Louis Rossman, an endodontist and president of the American Association of Endodontists.
