University of Florida researchers are experimenting with relaxin to augment the mechanical action of retainers and braces:

Relaxin is best known as the hormone that helps women's pelvic ligaments stretch in preparation for giving birth. It does this by softening collagen and elastin in the tissues, loosening strong, cord-like fibers until they have the consistency of limp spaghetti noodles.

That ability prompted researchers to consider relaxin a possible way to accelerate tooth movement and prevent relapse, a condition where the tooth migrates back to its original position after braces are removed.

"You can imagine normal collagen and elastin fibers to be like rubber bands that attach to the tooth to hold it in place," said Wheeler. "Those tissue fibers resist the force of the orthodontic treatment applied to move the tooth, and, when that force is removed, say when the braces are taken off, the elasticity of the tissues springs the tooth back into position."

UF researchers will evaluate whether injecting relaxin into the gums will loosen the collagen and elastin fibers and reorganize them so teeth can move more freely into orthodontic alignment. Once the teeth have been moved, researchers will administer another injection of relaxin under the premise that it will further soften gum tissue fibers, preventing them from pulling teeth back into their original position.

<![CDATA[Ultra Suction™ Does USA]]> Ultra Suction™ denturesMedGadget has learned that Ultra Suction™ denture system, originally mentioned by us in February, has finally secured FDA approval.

From the press release by Biomedics NZ Limited:

A New Zealand based company, Biomedics NZ Limited reports that it has obtained FDA approval for its Ultra Suction™, complete denture stabilizer system.

Biomedics NZ reports that Ultra Suction™ system comprises a tiny unidirectional device that is imbedded into a denture plate. As the denture wearer bites firmly, the air trapped between the gum and the denture is expelled through the device, via two air passages. The lower pressure obtained beneath the denture tends to exert a pull and helps secure the denture against the gum. Properly fitted dentures can increase wearing comfort, the ability to chew and therefore impact on the overall health of the patient.

Consider reading the original post on Ultra Suction™, as it contains some valuable comments from Mony Paz, M.D., the inventor of the device.

Liquid Medgadget? mouthwash
The American FDA wields some power over approving medical devices. It's certainly less stringent than their regulatory power over drugs, but sometimes there's a subtle distinction between what constitutes a drug or device. Here's some insight into how regulators decide, via a Reuters story about the Decapinol oral rinse:

The oral rinse is being regulated as a medical device and not as a drug because its primary mode of action is to create a physical barrier, rather than to act chemically. The product contains a surfactant that acts as a physical barrier, making it harder for bacteria to stick to tooth surfaces. FDA also has approved a number of other anti-gingivitis oral rinses, but since these products act chemically to kill bacteria that live in the mouth, they are regulated as antimicrobial drugs rather than as devices.

Dental Surgery Planning by TactileTech Tactile Technologies is the first company to offer accurate image-guided navigation relying on low-cost disposable elements, without involving any special equipment.Israel21c reports that a new start-up Tactile Technologies recently obtained US Food and Drug Administration marketing approval for its dental implant location software. The software is a three-dimensional solution for surgical planning. From the article:

The company's flagship product, which is in the final stages of development, is an Implant Location System (ILS) that uses a disposable micro-robot for carrying out dental implant procedures. The company promises that when this product hits the market, the process of getting dental implants will be less painful and less expensive.

[...]

The bone-sensing technology will enable precision three-dimensional measurement of bone tissue covered by soft tissue, without the need for invasive surgical procedures. The Implant Location System applies tactile sensing technology to offer intra-oral image-guided navigation specifically for dentists. Its computer-guided sensing, navigation and guiding suite for placement of dental implants is designed both for the general practitioner and the expert.

Tactile Technologies' aim is to help the firms that manufacture implants to find a solution for placing them that minimizes the risks and simplifies the procedure They are doing so using tactile sensing technology, three-dimensional radiological visualization and miniaturized robotic control which is changing the dental landscape.

Medgadget.com Goes to Frost & Sullivan's Awards
If you can't tell from our last few posts, we were really excited to be welcomed to Frost & Sullivan's "Excellence in Medical Devices & Healthcare Awards" banquet last night. After "the future's so bright i gotta put on my oakleys"-styled inspirational speech by Frost & Sullivan, we had the rare opportunity to listen to a legend in the medical device inventors guild - Alfred Mann of Advanced Bionics Co & MannKind Co. He waxed lyrical on the $9 B his companies have garnered for him, but much more on the revolutions they've brought about in pacemakers, insulin delivery (pump & inhaled), bringing hearing to the deaf and sight to the blind - biblical in importance. His philanthropy was equally impressive.

Over the next few weeks, we will present to you most (if not all) of the cool new inventions awarded last night.

Here's a sneak peek: the HydraBrush "automatic car wash for your mouth." We had a demonstration right up on the podium last night, pictured above. The description taken from company's website:

... "self-positions" relative to the teeth and gums... It has six (6) brushes that are positioned to correctly contact tooth and gum surfaces. The user simply bites into the brushing head, and self-positioning is automatic. The brushes reciprocate in short strokes in accordance with ADA recommended "Bass" brushing technique", (placing bristles 1/2 on teeth and 1/2 on the gums at approximately a 45 degree angle, and brushing with a short/quick back and forth action).

... relies on accurate bristle positioning to obtain effectiveness, and as a result, the brushes can reciprocate at a fraction of the speed of other products, resulting in user enjoyment of a comfortable massage with every use.

In addition to six brushes, HydraBrush™ has four (4) water jets that effectively oral irrigate during the brushing process. HydraBrush™ is much more effective than other oral irrigation devices because the water jets are preset to an angle that directs the pressurized fluid precisely into the gingival pockets and between teeth, again eliminating the element of human error.

HydraBrush™, with its six brushes and four water jets all working simultaneously, generates an oral cleansing with effectiveness far beyond that of any other oral care product. The cleaning process is also very enjoyable.

Hook me up! No, seriously. This product was the most accessible to any attendee, and ... I want one!


UPDATE (3/17/05):

You can see the photos here. Many thanks to Frost & Sullivan for a great event and many congrats to all the winners!

<![CDATA[Ultra Suction™ dentures]]> Ultra Suction™ denturesBiomedics NZ Limited, a New Zealand based company, claims to have invented a new type of denture: one with a better seal and with less undesirable effects, such as "shrinkage" of the gum. The system relies, essentially, on surface tension to keep the denture in place. The company describes:

Mony Paz from Biomedics NZ undertook a major redevelopment, taking into account today's understanding of material science and the physical mechanisms of denture retention.This revolutionary technology is now delivered in a comprehensive mounting system.

-- profiled bar has been developed to keep tissue proliferation to the minimum necessary for maintaining a seal. The specially formulated safe metal bar is fairly malleable, to fit any shape and contour of the alveolar ridge.

-- valves have been developed to expel the air and control the pressure level beneath the denture, using the specially formulated diaphragms.

-- processing cap has been developed with the dental practitioner in mind. The processing cap is specially designed to make the self curing procedure easy and safe, preventing damage to the valves.

-- service key has been designed to double as a gauge for both depth and diameter of the valve housing in the denture.

-- system is the result of research and laboratory development, lead by Mony Paz and Biomedics NZ team of professionals in the fields of product development, science and technology, dentistry and dental technology.
