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.
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 National Academy of Sciences (PNAS), “Stem Cell Fate Dictated Solely by Altered Nanotube Dimension".
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 short period of time," he said.
"With this evidence that we`ve reviewed, we think it`s not advisable for them to recommend it for the long, over a long period of time."
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.
Keystone Dental, funded by private equity firm Warburg Pincus, has settled an unfair competition lawsuit from Noble Biocare for $2million. "The settlement terms provide for Keystone Dental to pay $2 million to Nobel Biocare and that Keystone Dental not hire or solicit any current Nobel Biocare employee through February 1, 2009," the world`s largest maker of dental implants said in a statement. Nobel Biocare filed a lawsuit in late 2007, saying Keystone Dental systematically targeted and hired Nobel Biocare`s sales and marketing employees to gain an unfair competitive advantage. Under the settlement, Keystone Dental is required to destroy confidential and proprietary information on Nobel Biocare in its or its employees` possession, Nobel said.
Straumann revealed a new implant material, Roxolid [Rock-Solid], a Titanium- Zirconium alloy that is 50% stronger than pure titanium. Initial animal studies show a significant increase in removal torque values over Straumann`s current SLActive titanium implants. Human trials are underway in Europe and North America. Straumann expects to have the design released for initial markets in 2009.
The Wall Street Journal is reporting that Medtronic`s `Infuse Bone Graft` has been linked to life-threatening complications in dozens of patients. The FDA warned surgeons in July that it had received reports of life-threatening complications associated with using the product in surgeries on the cervical spine, around the neck. The agency said it received 38 reports over four years of side effects, mainly swelling of neck and throat tissue, which resulted in compression of the airway and other structures in the neck. Patients reported difficulty swallowing, breathing and speaking. Several required emergency treatment, including tracheotomies and the insertion of feeding tubes, as well as second surgeries, according to reports filed with the FDA.
Dr. Schubert Sapian has designed a innovative root removal system that extracts the entire root without sectioning. A specialized extraction screw is driven into the largest canal then a cushioned silicone fulcrum tray is placed over the adjacent teeth and a pry bar is used to apply vertical pressure to the root resulting in its atraumatic extraction.
Implant pioneer Gerald Niznick`s Implants Direct concept of internet-based factory-direct-to-dentist implant sales plans on launching a copy of the Straumann implant design in September. 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.
