Why does Nanova use nanofibers initscompositesinsteadofonlynano- particles like in other composites? High strength, great handling prop- erties and uncompromised esthetics are only some of the reasons these patent-pending nanofibers are the wave of the future in dental devices, according to the company. These hydroxyapatite nanofibers — manu- factured at the company’s Columbia, Mo., headquarters — are composed of a mineral found in nature: calcium phosphate. The trait that makes nanofibers so unique is the composition. They are made of calcium phosphate, the same structure as teeth and bone — a hard, inorganic mineral in a soft, organic matrix. For example, the enamel of a tooth is made up of high-volume, needle- like mineral crystals (approximately 15–20 nanometers thick and 1,000 nanometers long) in a small-volume, soft-protein matrix. Bone and den- tin are made up of plate-like crys- tals (approximately 2–4 nanometers thick and up to 100 nanometers long) embedded in a collagen-rich protein matrix. By comparison, the nanofibers have a thickness of less than 100 nanometers in diameter, or 1,000 times smaller than a human hair. Not only are they made of the same composition as the tooth they are restoring, providing a natural look, but this nanoscale size also provides unsurpassable strength. The strength found in nanofibers is because of its one-dimensional nature and large surface area. If you apply a shear force to a group of nano- particles, it is easy for the particles to slidebyeachother.Ontheotherhand, a fiber has a solid connectionrthat is stronger to resist bending, shear and tensile forces. Similar to rebar- reinforced concrete, these fibers add sturdiness to the composite by form- ing a framework. In comparison, dental glass or ceramic particles typically found in other dental composites have a ten- sile strength of approximately 50 MPa, which does not adequately rein- force a composite, causing repeat procedures on many patients. According to the Griffith theory discovered during World War I, it was found that needle-like mineral crystals could reach their theoretical strength when their diameters are in nanoscale. Microscopic flaws cause a material to fail, so by creating a nano- scale fiber, flaws are limited, provid- ing the ability to reach the material’s maximum strength. Nanova chose to produce this high- est level of strength while still allow- ing the fibers the mobility of bending without breaking. In addition, nano- scaled mineral crystals are not sensi- tive to cracks or stress concentration, which will degrade the material in the composite over time. This high strength and low sensitivity to cracks are the advantages provided by the nanofiber reinforced NovaPro com- posite line, according to the company. Why trust the quality of your work to any other composite? exhibitors 14 Hinman Dental Meeting — March 17, 2016 Nanofibers: Surpassing the gold standard of dental composites By Henry Schein Staff n Henry Schein Practice Solutions, the U.S. practice solutions business of Henry Schein Inc., has announced the availability of DEXIS™ for Dentrix Ascend® . DEXIS for Dentrix Ascend is a cloud- based imaging solution built exclu- sively for Dentrix Ascend to help cap- ture and store images to the cloud, eliminating the need for additional digital-imaging software and automat- ing daily procedures, such as insur- ance billing, to enhance efficiency and productivity in the practice. The software, initially available to users in North America, offers prac- titioners four key benefits, including seamless integration with Dentrix Ascend, enhanced digital workflow, quick access to images from the cloud and automatic upgrades and backups that reduce the need for maintenance and hardware. In addition, practices nolongerneedtoleaveDentrixAscend andopenaseparateapplicationtocap- ture, store and manipulate images. With the cloud-based system, patient X-rays and intraoral images are available to all authorized devices and users on the system from any location, saving time for clinical pro- cedures. “DEXIS for Dentrix Ascend is another example of Henry Schein’s commitment to providing digital solu- tions that improve our customer’s practice workflow so they can focus on providing better clinical care to patients,” said Rhett Burnham, vice president, product management. “Working with DEXIS, we were able to build the imaging features directly into Dentrix Ascend so critical tasks are automated, helping practitioners maintain patient clinical history and improve insurance and billing work- flow.” The cloud-based system captures original digital images and uploads them(notacopy)withvirtuallynoloss of quality, thanks to a compression algorithm that provides fast upload speeds to help maintain image qual- ity. Once in the cloud, the images can be edited using a variety of tools, including filters, annotation and den- sity reading. “DEXIS for Dentrix Ascend has helped make our practice’s insurance billing more efficient. I also really like having the ability to remotely view, with clarity, an X-ray from anywhere when consulting with patients or col- leagues,” said Dr. Mau Nguyen, New- port Commons Dental Care.
