Phillips CT Scan increases clarity, reduces radiation

The Philips `Brilliance` CT scanner was unveiled at the Radiological Society of North America. The new 256-slice CT machine takes large numbers of X-ray pictures, and combines them using computer technology to produce the final detailed images.
It also generates images in a fraction of the time of other scanners: a full body scan takes less than a minute. This scanner allows radiologists to produce high quality images and is also designed to reduce patients` exposure to X-rays,” Steve Rusckowski, chief executive of Philips Medical Systems, said. “It is so powerful it can capture an image of the entire heart in just two beats.” “This is a quantum shift from the first CT scanners as it gives a lot more detail,” says Dr Keith Prowse, Chairman of the British Lung Foundation.

Rattlesnake Venom-derived Fibrin Adhesive used in Periodontal Surgery

A new study in the October issue of the Journal of Periodontology (JOP) found that an adhesive made from an enzyme found in snake venom was a more effective and beneficial adhesive when used to close surgical incisions than traditional sutures. The study followed 15 patients during the healing process after a gingival (gum) graft. When the adhesive derived from snake venom was used, those patients had faster recovery and better results than those treated with traditional sutures. `This unique type of adhesive may stimulate faster tissue repair. It is a more natural form of adhesive in comparison to traditional sutures used after surgery,` explained study author Monica Barbosa, Phd, Bauru Dental School at the University of Sao Paulo, `More studies are needed to fully evaluate the effectiveness of this alternative.`
`This adhesive may be a less infectious alternative to traditional sutures,` said Preston D. Miller, DDS, and AAP president. `This research highlights the array of therapies available for patients; both traditional and natural alternatives. There continues to be a lot of exciting and innovative research in the field of periodontics.`

Increase in CT Scan use increases Cancer Risk

A New England Journal of Medicine article found that the number of CT Scans most people are exposed to had risen dramatically in the past 27 years. In 1980, doctors ordered an average of 3 million scans per year in the United States. Now, about 62 million CT Scans are done each year in this country. The rise in CT Scans can be attributed, in part, to an increase in `defensive` medicine. This occurs, for example, when people who are admitted to an emergency room are routinely given a CT Scan even before receiving a diagnosis or being seen by doctor. Controversial uses of CT Scans for whole-body scanning, virtual colonoscopy and lung cancer screening have also made CT Scans more prevalent.

The dose of radiation received by patients subject to a CT Scan can be 50 to 100 times larger than that of a traditional x-ray. That is exactly where the problem of CT Scan overuse lies. The type of radiation used in CT Scans, ionizing radiation, has the capacity to damage DNA, causing cells to mutate. This in turn leads to cancer. While the risk of one CT Scan to an individual is small, the study`s authors wrote that they are concerned about the built-up risk of frequent CT Scans over time. In a few decades, as many as 2% of all cancers in the United States might be caused by radiation from CT scans given now.

BioMedevice`s GumEase – Cryo-Anesthetic Dental Mouthpiece

BioMeDevice Ltd. today announced that it has received FDA approval to market the new and innovative gumEase Cryo-Anesthetic dental mouthpiece to US dental practitioners and over the counter across the United States. The easy-to-use, disposable device is a breakthrough in pain management. Inserted into the sulci above and below the upper and lower gums, the latex-free device delivers anesthetic pain relief to the maxillofacial nerves, quickly diminishing pain. In patient testing the new gumEase diminished pain by 90% in 3 to 4 minutes for the average participant.The gumEase is a sterile device made of biocompatible ThermoPlastic Elastomer (TPE) containing a saline solution. A `standalone` device, gumEase is not connected or supported by any other means. The device is chilled in a temperature controlled freezer, and as soon as the device is placed in the proper sulci of the mouth, the cooling transfer begins – with a surprisingly powerful effect on patient pain relief. Possible side effects associated with the use of gumEase is the potentiality that the cryotherapy will not have a totally and comprehensive disruption of oral pain.

META – Sin Crest System for Minimally Invasive Osteotome Sinus Lifts

META Advanced Medical Technology have designed a osteotome based sinus lift system that accomplishes a controlled crestal osteotomy and the lifting of a cortical operculum which adheres to the sinus membrane in a safe manner, without damaging tissue. The SinCrest drills are equipped with depth stops that allow obtaining a guiding hole in the alveolar bone as close as possible to the maxillary sinus membrane. The innovative SinCrest manual osteotome was designed to obtain the controlled fracture of the bone floor through a 0.5 mm step-by-step progress. The probe included in the SinCrest osteotome allows the constant monitoring of the residual resistance of the maxillary sinus and its lifting without leading to the perforation of the sinus membrane. The SinCrest technique may be used in case of a residual bone availability ranging from 5 to 11 mm and in any sufficient anatomic condition to stabilise the osteotome in the implant site.

Straumann to test Mussel-Based Implant Adhesive Coating

Over the course of evolution mussels have developed a special glue that not only works under water, but is also a particularly firm and lasting bonding agent. The strength of the bond is due to a particular protein.
Dr. Klaus Rischka, a chemist at the Fraunhofer Institute for Manufacturing Engineering and Applied Materials Research IFAM in Bremen and his partners at Frankfurt University Hospital, the Center of Biotechnical Engineering BitZ at Darmstadt University of Technology, the State Materials Testing Institute MPA and the implant manufacturer Straumann in Freiburg will initially demonstrate the glue`s suitability on the basis of a dental implant made of titanium.
It is current practice to anchor tooth implants in the jaw bone without an adhesive. This often leaves gaps between the gums and the metal, allowing bacteria to enter and cause infections. A glue that firmly connects the gums to the implant would serve as an effective barrier against aggressive germs.
Conventional products are not suited to such a purpose, however, as they would sooner or later dissolve in the moist environment inside the mouth.
The use of this substance in medical applications requires an additional ingredient: a growth protein, which can likewise be synthetically produced using the classic technique of solid-phase peptide synthesis. Its purpose is to stimulate cell growth so that the body`s own tissue -in this case the gums – bonds as closely as possible with the implant.

Materialise Sues Nobel Biocare for Patent Infringement over NobelGuide

Materialise has filed a US lawsuit against Nobel Biocare for patent infringement. Materialise contends that Nobel Biocare’s manufacture of “NobelGuide” drilling template violates a Materialise U.S. patent that was issued in 1998 relating to Materialise’s “SurgiGuide” techniques. The lawsuit in the U.S. is effectively an extension of a similar action in Europe where this past August the District Court of Dusseldorf ordered Nobel Biocare AB and Nobel Biocare Deutschland GmbH to stop offering the NobelGuide drilling templates in Germany, finding that they infringed Materialise’s analogous European Patent. This decision is subject to an appeal of Nobel Biocare pending at the Düsseldorf Court of Appeals. Materialise’s U.S. lawsuit is also a response to a recent Nobel Biocare civil action (also filed in the Central District Court of California) that seeks declaratory judgments that Materialise’s U.S. patent is both not infringed by Nobel Biocare’s products and is invalid. Bart Swaelens, CEO of Materialise Dental, said: “With this lawsuit, we are protecting our technology. Our “SimPlant” software was launched in 1991, and was followed by our “SurgiGuide” drill guides in 1999. The introduction of NobelGuide by Nobel Biocare, on the other hand, did not occur until 2005. “

Device for Ultrasonic Imaging of Jaws – US Patent Issued

Imadent was issued a US Patent for its ultrasonic jaw imaging system. The system includes a specially configured ultrasonic probe, a position locator module for defining the probe location and transmitting the definition to a computer which re-assembles the image. Imadent is one of the first companies that has been able to use ultrasound technologies to create high-resolution, cross-sectional images of hard tissues such as bone. The company’s technology allows for real-time imaging of a patient’s jaw during dental surgery, increasing the safety and efficacy and lowering the cost of dental implantation and other dental surgical procedures. “Imadent’s technology uses ultrasound, a harmless imaging technology, to image hard tissues such as bones, and that is a major breakthrough,” said BioEnterprise Corporation President Matt Jennings. “The proper placement of dental implants is critical as misplacement can cause permanent nerve or sinus damage. Imadent’s technology can significantly lessen the possibility of such damage, making the procedure safer, more affordable, and thus more attractive to both patients and clinicians.”

Harvard Researchers Pioneer Pain-Specific Local Anesthesia from Chili Peppers

The new method exploits a membrane-spanning protein called TRPV1, which is unique to pain-sensing neurons. TRPV1 forms a large channel, where molecules can enter and exit the cell. But a “gate” typically blocks this opening. The gate opens when cells are exposed to heat or the chili-pepper ingredient capsaicin. Thus, bathing pain-sensing neurons in capsaicin leaves these channels open, but non-pain sensing neurons are unaffected because they do not possess TRPV1.

“We’re optimistic that this method will eventually be applied to humans and change our experience during procedures ranging from knee surgery to tooth extractions,” adds Professor Clifford Woolf of Massachusetts General Hospital, who is senior author on the study
Despite enormous investments by industry, surgical pain management has changed little since the first successful demonstration of ether general anesthesia at MGH in 1846. General and local anesthetics work by interfering with the excitability of all neurons, not just pain-sensing ones. Thus, these drugs produce dramatic side effects, such as loss of consciousness in the case of general anesthetics or temporary paralysis for local anesthetics.
“We’re offering a targeted approach to pain management that avoids these problems,” says Woolf.

“Eventually this method could completely transform surgical and post-surgical analgesia, allowing patients to remain fully alert without experiencing pain or paralysis,” says Woolf.

Implantology – What NOT to do

A Washington State disciplinary board has fined a Lynnwood dentist $10,000, suspended his license at least through the end of the year and ordered him to take 41 hours of continuing education courses. The case involved a patient treated between June 2004 and November 2006 who needed nine dental implants. In its order, the commission found that the dentist failed to adequately examine, assess, evaluate, diagnose or develop a treatment plan for the patient.
He did not adequately check out the patient`s complaints of severe pain during eight follow up visits after the surgery. One of implants had either been installed in or had migrated into the patient`s sinus cavity, the commission found. No X-rays were taken for six months following the surgery, according to the disciplinary board. The dentist also prescribed more than 3,148 tablets of two narcotics for pain, Oxycodone and Percocet, during a 29-month period ending in November 2006. The commission said that he did not document the reasons for prescribing the high levels of narcotics, calling it extremely excessive.
The commission officially suspended his license for seven years. However, the suspension could be put on hold after Jan. 1 if he meets the continuing education, mentoring and other requirements specified in the order.
The dentist`s attorney has requested reconsideration of one part of the order, which prevents him from doing surgical implant procedures.

MIT Investigates Molecular Mechanism Responsible for Bone`s Toughness

Professor Markus Buehler of MIT`s Department of Civil and Environmental Engineering has revealed for the first time the role of bone`s atomistic structure in a toughening mechanism that incorporates two theories previously proposed by researchers eager to understand the secret behind the material`s lightweight strength. He studied the molecular structure of the mineralized collagen fibrils that make up level 2 bone, hoping to find the mechanism behind bone`s strength, which is considerable for such a lightweight, porous material. When pressure is applied to the fabric-like fibrils, some of the weak bonds between the collagen molecules and crystals break, creating small gaps or stretched areas in the fibrils. This stretching spreads the pressure over a broader area, and in effect, protects other, stronger bonds within the collagen molecule itself, which might break outright if all the pressure were focused on them. The stretching also lets the tiny crystals shift position in response to the force, rather than shatter, which would be the likely response of a larger crystal.

Abraham Lincoln may have had a Facial Defect

The left side of Lincoln`s face was much smaller than the right, an aberration called cranial facial microsomia. The defect joins a long list of ailments – including smallpox, heart illness and depression – that modern doctors have diagnosed in Lincoln. Laser scans of two life masks, made from plaster casts of Lincoln`s face, reveal the 16th president`s unusual degree of facial asymmetry. The scanning technique is usually used to create 3-D images of children with cleft lip and palate before and after surgery. Dr. Ronald Fishman, who led the study published in the August issue of the Archives of Ophthalmology teamed up with Dr. Adriana Da Silveira, an Austin, Texas, orthodontist who specializes in children with facial defects, to scan a bronze and a plaster copy of two life masks, owned by the Chicago History Museum.

Inkjet Printers Produce Custom Bone Grafts

Tissue Engineering Researchers at the University of Tokyo Hospital and venture company Next 21 are using 3D inkjet printers to produce tailor-made artificial bones for use in facial reconstructive surgery. To make an artificial bone with this technology, a 3D computer model of the bone is first created based on the patient’s X-ray and CT scan data. The computer model is then sliced into a large number of cross-sections and the data is sent to a special 3D inkjet printer, which works like an ordinary inkjet printer by transferring tiny droplets of liquid onto a surface. However, unlike ordinary printers that print on paper, this one prints onto thin layers of powdered alpha-tricalcium phosphate (alpha-TCP). The “ink” is a water-based polymer adhesive that hardens the alpha-TCP it comes into contact with. By repeatedly laying down the powder and printing successive layers on top of one another, the printer is able to physically reproduce the desired bone to an accuracy of one millimeter

The response called the initial report to the Swedish Medical Products Agency (SMPA) on NobelDirect by Dr Albrektsson as `… incomplete and reported in an unscientific way. The analysis of the present manuscript shows that the material still suffers from intransparency and lack of scientific stringency. The process for peer-review may even be questioned.`

Trinon`s Short Q-Implant

Trinon has designed a series of extremely short, but wide implants designed for use in areas of limited alveolar height. This design is appropriate for severely atrophied, but wide lower and upper jaw architectures. Insertion is via trephine use and are very appropriate for internal sinus lift use. The implants range in size from 4mm to 7mm in height.

One Minute Extraction – Physics Forceps

GoldenMisch has developed a set of extraction forceps. Its design delivers a powerful mechanical advantage by employing an efficient first-class lever. The forceps feature a bumper which is set low on the alveolar ridge, perpendicular to the tooth, creating a good fulcrum point. The Physicsforceps makes only one point of contact with the tooth, as opposed to conventional forceps that work like pliers. The website shows various testimonials and animation of the `rolling` extraction technique.
