3M Unitek, Monrovia, Calif, has released new data regarding the benefits of its APC™Flash-Free Adhesive coated appliance system, which eliminates the flash removal step in bonding and reduces bonding time by as much as 40% per bracket.
With APC Flash-Free Adhesive, a small amount of resin flows out from under the bracket during seating. This resin forms a meniscus or fillet around the edges of the bracket which, once cured, has been shown to stay in place for the duration of the treatment, according to the company. New data shows that the cured APC Flash-Free Adhesive resin material protects covered enamel from the softening effects of acid exposure. While other adhesive products may require sealant applications every 6 months, the new data, published in 3M Unitek’s Orthodontic Perspectives Innova, a clinical publication for orthodontic professionals, shows that APC Flash-Free Adhesive not only stands up to wear from tooth brushing, but additionally protects the meniscus covered enamel from acid erosion.
In addition, researchers at the University of Minnesota, Minneapolis, conducting a new in vitro university study, found that users of APC Flash-Free Adhesive report the product enables more consistent and predictable debonding compared to traditional paste adhesive systems.
According to the company, the resin used in APC Flash-Free Adhesive contains less filler; therefore, while providing reliable bond strength, an added benefit is improved ease of cleanup of adhesive remnants after debonding. Data shows that the adhesive is softer, suggesting that less force on the handpiece is required to remove remnants, and that the remnant material is more pliable than alternative systems. Similarly, clinicians found that a low speed handpiece is sufficient for removal of the material, and that they are able to delegate this task to an assistant. The easier adhesive removal process also makes the debonding appointment more comfortable for patients, allowing them to experience a smoother, quicker and more comfortable debonding process.
APC Flash-Free Adhesive is available with Clarity™ ADVANCED Ceramic Brackets in both the MBT™ Appliance System and Roth prescriptions. The system is available in a growing list of regions, including the United States, Canada, Europe, Australia, Asia, Latin America, and more.
