AAE: Dental Implants Require Much More Follow-up Treatment than Root Canals

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

Nanotubes and Stem Cells Accelerate Bone Growth

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

Alcohol Containing Mouth Rinse linked with Increased Cancer Risk

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

BioImplant: Individualized Zirconium Dental Implants

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 settles with Nobel Biocare for $2million

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

Straumann`s Roxolid TiZr Alloy Implant in 2009

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.

Infuse Bone Graft Linked to Life-threatening Complications in Dozens of Patients

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

Sapian Root Removal System

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.

Emdogain – Available in the USA again

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.
