Researchers at the Regea Institute of Regenerative Medicine, part of the University of Tampere, Finland have successfully replaced a 65-year-old patient`s upper jaw with a bone transplant cultivated from stem cells isolated from his own fatty tissue and grown inside his abdomen. Stem cells were isolated from the patient`s fat and grew for two weeks in a specially formulated nutritious soup that included the patient`s own blood serum. When they had enough cells to work with, they attached them to a scaffold made out of a calcium phosphate biomaterial and then put it inside the patient`s abdomen to grow for nine months. The cells turned into a variety of tissues and even produced blood vessels, the researchers said. The block was later transplanted into the patient`s head and connected to the skull bone using screws and microsurgery to connect arteries and veins to the vessels of the neck. The patient`s upper jaw had previously been removed due to a benign tumor and he was unable to eat or speak without the use of a removable prosthesis.

Aspiring Mexican dentists are moving to border cities in droves and are luring American patients away from farther flung discount destinations such as Hungary and Thailand. A dental crown in the United States costs upward of $600 per tooth, compared to $190 or less in Mexico. Americans have long crossed the border for cheap medicines, flu vaccines, eye surgery or specialist doctors, but dentists are now in highest demand. "We`ve gone from a handful of patients when we started 2-1/2 years ago to 150 new patients a month," said Joe Andel, an American who owns the Rio Dental clinic in Ciudad Juarez with his Mexican dentist wife, Jessica. Rio Dental, which uses U.S. labs to make its crowns, picks patients up at the airport in El Paso, Texas, across the border and has treated people from as far away as Alaska and Hawaii. "The Internet makes this possible. It allows patients to find us and research us and shows we can do dental work of equal or superior quality to the United States," Andel said. Internet bloggers swap stories and compare notes about Mexican dentists, but it always comes down to money.

Three years after patients were given Nobel Direct dental implants, the risk of the implant loosening has increased even more. A follow-up by researchers at the Sahlgrenska Academy shows that eight per cent of the implants are lost. "We have followed up 48 patients who were among the first to get the implant. For each passing year, we have been able to see how the problems related to these implants have grown more and more,” observes Pär-Olov Östman, a dentist who will be presented the study tomorrow at the defense of his dissertation. After one year, about five per cent of the implants had been lost, and 20 per cent of the remaining implants showed bone loss of more than three millimeters. The new report indicates that after three years, eight per cent of the implants had been lost, and 25 per cent of the remaining implants showed bone loss of more than three millimeters. “We believe that the problems related to Nobel Direct result both from the design of the implant and an uneven surface against the soft tissue in combination with the method of treatment recommended by the company,” according to Professor Lars Sennerby.

Researchers at The University of Texas Health Science Center at Houston can identify and quantify specific protein markers in human saliva to provide an early, non-invasive diagnosis of breast cancer, according to a study published in today’s issue of the journal Cancer Investigation. “Why not the dentist?” said lead researcher Charles Streckfus, D.D.S., . “Most folks, especially women and children, visit the dental office way more often than they ever see the physician. Saliva is a non-invasive, quicker way for detection.” Streckfus and his team compared the levels of expression of proteins in the saliva of patients with either malignant or benign tumors to saliva from normal controls to find those that are abnormally expressed in the diseased state. Patients’ proteins that are significantly higher or lower than the norm were considered biomarker candidates. Streckfus and his collaborators are continuing to pursue salivary diagnostics for other types of cancer, such as ovarian, endometrial, cervical and head and neck cancers.

Researchers at the Chemistry and Biochemistry Department at National Chung Cheng University in Taiwan has published a paper in Nanotechnology demonstrating the use of gold nanoparticles in occluding dental tubules. Researchers have found that sensitive teeth have an increased number of dentinal tubules (35.6% compared to 9.3%) and are wider in diameter (0.83 µm compared to 0.43 µm) than the dentinal tubules of non sensitive dentine. The Chinese researchers have demonstrated that this tubules can be blocked with the aid of gold nanoparticles. An interesting aspect of gold at the nanoscale is that gold nanoparticles exhibit a clear size-dependent trend: the smaller gold nanoparticles get, the lower is their melting point. This deviation of the melting temperature from the bulk value becomes dramatic at a size around 5 nm in diameter, ultimately reaching well under 50% of the bulk melting point of gold.One of the methods of closing sub-micron sized dentinal tubules explored by Dr. Chris Wang and his team involved the sintering of highly concentrated gold nanoparticles that were brushed into the exposed open ends of dentinal tubules. Laser irradiation induced the photofusion of gold nanoparticles via photothermal conversion.

Creative Marketing and Merchandising Media Solutions (c3ms), a provider of digital signage networks, recently announced the launch of the NobelVision Network throughout North America. The NobelVision Network is a customized channel of dental healthcare information specifically designed to educate the patients of Nobel Biocare`s customers on their dental options by delivering quality educational, informational and entertainment segments via an IP-based, networked narrowcast system. Presented on large flat-panel screens installed in dental offices, the NobelVision Network provides a unique opportunity for advertisers and content partners to market their products and services to a targeted, health conscious audience with known demographic and statistical data. With the growing population of patients who actively research their own healthcare options, having fresh, up-to-the minute information that`s pertinent to their needs makes the wait in the dentist`s office a more productive experience," said Kevin Mosher, Vice President & General Manager, Nobel Biocare North America. "For dentists, it`s always better to have educated patients, particularly when they become knowledgeable about additional services that may be of benefit to them. The NobelVision Network represents a strategic vehicle to deliver timely and relevant information in an appropriate setting for the benefit of both parties." Implementation of this private promotional and advertising network is currently underway and will be installed in 200 dental offices using Nobel Biocare products by the end of 2007

Regeneration technologies have started to manufacture bone screws from bovine metatarsals. These are used in reconstructive surgery such as repairing the torn anterior cruciate ligament that plagues many athletes. The bone is obtained from specially bread cows at the Pranther Ranch. Prather Ranch "allows us the opportunity to satisfy many concerns about sourcing bovine materials because of the way they do their business," said Carrie Hartill, chief scientific officer at Regeneration. "They are the largest closed herd and safeguarded with proper health and animal husbandry." In addition to the special precautions Rickert takes in breeding his cattle, the cow bones need special preparation before they can be used in human surgery. Regeneration and other companies use cleaning techniques (Regeneration`s proprietary version is called BioCleanse) to ensure that no living material remains on the bone. That cuts down on the risk of disease transmission and prevents antigenicity, which happens when the body`s immune system attacks a foreign substance.With clean bones, the work of turning bone into bone screw can begin. "The first thing we do is shape into rough-hewn shapes around the size and specification you might need," Hartill said. "Then you do the fine machining. It`s actually a screw and it has a thread, so we use identical (cutting and milling) equipment to the titanium-screw manufacturers." The selling point for using bovine biological materials is that the body responds to it as it would human tissue, absorbing it into the body. "It eventually remodels into the host bone from six to 12 months" after surgery, Hartill said. "We have instances where surgeons have had to go in to do a repeat surgery and they haven`t been able to find the bovine bone anymore."
