Martin Jones, 42-year-old builder, was left blind after an accident at work more than a decade ago. After a remarkable operation in which part of his tooth was implanted in his eye, he can now regain some of his lost sight. The procedure involved taking a minute section of a patient`s tooth, reshaping and chiselling through to grip the man-made lens which was then placed in its core. It is implanted under an eyelid where it become covered in tissue.
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

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
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
The JDMultiscraper is designed for autologous bone harvesting. It features a autoclavable body with interchangeable blades, which can be changed once cutting performance degrades.
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
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
UC San Diego bioengineers and material science experts used a nano-bio technology method of placing mesenchymal stem cells on top of very thin titanium oxide nanotubes in order to control the conversion paths, called differentiation, into osteoblasts or bone building cells. Mesenchymal stem cells, which are different from embryonic stem cells, can be extracted and directly supplied from a patient’s own bone marrow. The researchers described their lab findings in a paper published this week in the Proceedings of the
Australian researchers have linked mouthwash containing alcohol to an increased risk of developing oral cancer. The alcohol in mouthwash is believed to allow cancer causing compounds to attack the lining of the mouth more easily. The review author, Michael McCullough, is an Associate Professor in Oral medicine at Melbourne University. He says dentists need to be aware of the risks of mouthwash. “If they are going to recommend alcohol-containing products then they recommend it for a good reason, for a
Austrian Surgeons have designed a system to produce via CAD/CAM individualized Zirconium Dental Implants for use in case of immediate implant placement. In short, after a tooth is extracted it is scanned and a zirconium copy is milled. The milled copy has macro-retentive features which help secure the new implant in the extraction socket. They report a 90% success rate.

Having already successfully marketed a copy of Nobel Biocare`s implant designs. Read this interview with an European trade journal for interesting details of the strategy.
The FDA has reinspected the BIORA facility and is satisfied with the improvements made. Because the focus of the observations was on the maintenance of quality system documentation and procedures, changes to Straumann® Emdogain, Straumann® PrefGel and Straumann® BoneCeramic were not needed in order to resolve the FDA issues. Straumann has changed the delivery mechanism of Straumann® PrefGel from a pipette to a syringe, which will help to ensure easier, more effective handling of the root conditioner.
A court in Germany has dismissed a request from Belgian dental implant software maker Materialise for an injunction against a Nobel Biocare software product, NobelGuide. Belgium software maker, Materialise had alleged the updated version of Nobel Biocare`s NobelGuide software infringed one of its patents, a spokesman for Nobel Biocare told Reuters on Wednesday. The Duesseldorf district court decided that the NobelGuide software does not infringe the Belgian company`s patent. The updated version had been introduced as a response to last
Canadian researchers at the NRC Industrial Materials Institute (NRC-IMI) in Boucherville, Quebec have developed a porous titanium foam implant said to mimic a metallic version of bone. The titanium foam is made by mixing titanium powder with a polymer, and then adding foaming agents that expand the polymer when heated. Later, through a high-temperature heat treatment, the polymer is removed and the titanium particles are consolidated to provide mechanical strength to the porous structure. Porous titanium had previously been used
Canadian researchers at the University of Alberta have found the surface nanocrystallization of a metallic material is an effective approach for modifying the surface energy of metals. “Our results demonstrate that the combination of surface nanocrystallization and thermal oxidation treatment is a promising approach to suppress the formation of infectious biofilms on metallic materials, thus providing a surface technique to minimize bacterial biofilms on implant surfaces for improved orthodontic and orthopedic applications” says Li the lead researcher. This surface modification

A report by scientists from the Netherlands published in the FASEB Journal identifies a compound in human saliva that greatly speeds wound healing. Scientists found that Histatin, a small protein in saliva previously only believed to kill bacteria was responsible for the healing. Because saliva is a complex liquid with many components, the next step was to identify which component was responsible for wound healing. Using various techniques the researchers split the saliva into its individual components, tested each in
Dr. Jong-Ho Lee, a Korean dentist, has patented his design for a free-angled screwdriver and abutment. The system addresses the prosthetic problem of access screw hole placement. The free-angled driver consists of 2 to 3 sections connected using universal joints which allows the unrestricted rotation of the free-angled driver at any angle. The free-angled driver eliminates the need for a straight channel to access the abutment screw. The abutment screw can be screwed and unscrewed using the curved channel up
Michael Mastromarino, the leader of the body-snatching ring that plundered the corpse of broadcaster Alistair Cooke apologized to the victims as he was sentenced to 18-54 years in prison. “I am deeply sorry for all the emotional pain I have caused to donor families and donor recipients,” he told the Brooklyn Supreme Court in New York. Mastromarino once ran a dental practice on New York`s Fifth Avenue specializing in dental implant surgery. But he was forced to surrender his dental
Novel processing of commercially pure titanium (CP Ti) has produced exceptional mechanical properties and recent clinical trials have proven its superior biocompatibility as well. CP Ti is desirable mainly for its superior biocompatibility, but suffers from low strength compared to either steel or alloyed titaniums. Severe plastic deformation (SPD) processing aims to get microstructural refinement to a level not achievable with traditional processing yielding nanocrystalline titanium. Fatigue life has nearly doubled and although damage tolerance suffered, the levels are still
Bioengineers and bioscientists at Rice University and Radboud University in Nijmegen, Netherlands, have shown they can grow denser bone tissue by sprinkling stick-like nanoparticles throughout the porous material used to pattern the bone. To grow new bone, tissue engineers typically place bone cells on porous, biodegradable materials called scaffolds, which act as patterns. With the right chemical and physical cues, the cells can be coaxed into producing new bone. As the scaffold degrades, it is replaced by new bone. “Ideally,
SurgeryTec is a Netherlands based website that allows members to upload and share surgical technique videos and slideshows. The site has a majority of medical surgery related videos, but some oral surgery/implantology related surgeries are also included.
A shortage of NHS dentists is leading to thousands of needless deaths from mouth cancer, according to dental experts. “The survival rate of mouth cancer has not improved in 30 years,” Nigel Carter, chief executive of the British Dental Health Foundation said. “If people were able to gain easier access to a dentist then the 50 per cent mortality rate could be significantly improved. It is Britain`s secret cancer despite killing more people annually than cervical and testicular cancer put

The Baha system utilizes direct bone conduction, which allows the bone to transfer sound to a functioning cochlea – thereby bypassing the middle ear. This unique hearing treatment is the only system of its kind cleared by the Food and Drug Administration (FDA) to treat hearing loss. One reason the Baha system works so well is due to its simple design. The Baha system combines a sound processor with an abutment and a small titanium implant. The implant is placed
Tighter laws are on the cards for dentists wishing to practice implantology in Dubai. A proposed change in policy will require dentists to complete 100 hours of implantology study and to present completed case reports, before being permitted to sit for the oral licensing exam. The move is set to infuriate local product companies, who have previously complained of the United Arab Emirate`s excessive licensing requirements.Industry-led courses are likely to be most affected by the ruling, as most are structured
Michael Mastromarino, 44, was arrested nearly two years ago, and this month he plead guilty. Mastromarino and two of his associates were charged in 2006 with enterprise corruption, body stealing, opening graves, unlawful dissection and forgery. Authorities released photos of exhumed corpses that were boned below the waist. They said the defendants had made a crude attempt to cover their tracks by sewing PVC pipe back into the bodies in time for open-casket wakes. The bodies came from funeral homes
Researchers at the University of Ankara, Turkey have designed an innovative CAD based implant guide. The design features a plastic stent produced by rapid prototyping methods that snugly fits the implant handpiece and uses a square slot system to guide the drill direction as opposed to the metal/plastic sleeves used by similar systems. This allows for better visualization of the surgical area and negates the use of stepped sleeves of increasing diameter to guide the twist drill. Additionally it eliminates
