PROVIDES SIGNIFICANT SEPARATION FORCE
"Comparing the separation force of several popular separating rings, the DualForce™ Rings recorded the highest separating force (34N) of any ring tested. This separating force may be attributed to the two independent rings, as well as the contour of the feet, allowing for a tight adaption of the matrix to the buccal and lingual walls of the preparation."

Dr. Nate Lawson is the Director of the Division of Biomaterials at the University of Alabama at Birmingham, School of Dentistry and the program director of the Biomaterials residency program. He graduated from UAB School of Dentistry in 2011 and obtained his PhD in Biomedical Engineering in 2012. His research interests are the mechanical, optical, and biological properties of dental materials and clinical evaluation of new dental materials.
IDEAL FOR MOST CLASS II RESTORATIONS
"Placing a sectional matrix should require some force during placement. Clinicians can’t achieve proper interproximal contact without tension in the ring. DualForce Rings are uniquely engineered with two NiTi rings that decrease the force needed during placement while increasing the separation
force, resulting in an idealized interproximal contact on Class II restorations."

REDUCES FINISHING TIME
"The DualForce Sectional Matrix System takes the best features of other systems and improves on them; the DualForce™ Active-Wedges™ have been transformative and along with the DualForce™ Ultra-Wrap™ Matrix
Bands, they create a tight seal at the gingival and proximal margins through better adaptation to the tooth which minimizes flash and finishing time"

Dean Kois, DMD, MSD
Dr. Dean Kois received his Doctorate in Dental Medicine from Nova Southeastern University, College of Dental Medicine. He went on to specialize in Prosthodontics receiving a Certificate in Prosthodontics with a Master’s of Science degree from the University of Washington, School of Dentistry, and then completed a surgical Implant Fellowship at New York University, College of Dentistry. He continues to lecture nationally and internationally all while maintaining a private practice in Seattle. In addition, he continues to work with restorative dentists at the Kois Center, a didactic and clinical teaching program.
CREATES NATURAL CONTACT POSITION AND SHAPE
"The unique and anatomically correct design of the DualForce Ultra-Wrap Matrix Band allows for ideal contour of the interproximal anatomy and marginal ridge in Class II restorations. It can be extremely difficult to sculpt and contour these surfaces. Therefore, having a matrix that is easy to place
and reliably replicates the ideal contour of the natural dentition ensures the long-term success of all restorations."

BLEND WITH NATURAL TOOTH STRUCTURE
"The key criteria for composite resins to blend into natural tooth structure undetectably, is the adequate amount of opacity in the resin itself at a
given thickness. Evanesce dentin shades with 90% opacity, along with enamel shades having an 80% opacity, provide the correct recipe to block out the tooth/composite transition, allowing the restorative material to blend seamlessly into the tooth structure to ensure invisible margins. This is a result of its nanopigments and fillers that maximize its refractive and
reflective indices. For all my direct restorative cases, I have absolute confidence in Evanesce to flawlessly mimic the beauty of the natural tooth in any direct restorative scenario."

PREVENTS WEDGE BACK-OUT
"The unique DualForce Active-Wedges have a collapsible tip that collapse as you place it through the proximal contact. Once through the palatal or buccal side, it expands to prevent the wedge from backing out and establishes this ideal cervical seal that will be there through the entire procedure."

Dr. Geissberger graduated from the University of the Pacific in 1991 obtaining his dental degree and was elected to
Omicron Kappa Upsilon as a student. He immediately returned to the school and has taught for 27 years, obtaining the rank of Full Professor. He obtained a Master of Arts in Educational Psychology from the University of the Pacific. From 2000- 2015 he served as Department Chair of Restorative Dentistry.
POLISHABILITY
"Evanesce is highly polishable with shades that blend seamlessly into the margins to virtually disappear. In less than 1 minute, in combination with A.S.A.P. Polishers, you can polish Evanesce to a high shine. The best composite restoration is the one that cannot be detected, Evanesce provides that, and a long lasting polish on all my direct restorations."

OPACITIES
"Evanesce is available in the most popular VITA shades with three opacity options: Enamel, Universal and Dentin. The material also comes in three “Enamel FX” shades: White, Incisal and Clear along with two bleach shades for additional shade-matching precision. Evanesce’s opacity selection
allows for a more enhanced and excellent esthetic result that disappears into the existing tooth surface."

SCULPTABILITY
"Innovative chemistry within Evanesce enables anatomy to be sculpted without slumping, and the material can be adapted to the preparation or thinned out along the surface without fear of pull-back or sticking. This allows you to easily sculpt intricately detailed anatomy and place thin
layers without worrying about slumping."

DESIRABLE PHYSICAL PROPERTIES
"Strong and versatile, this nano-hybrid composite features the characteristics of a direct restorative material intended to replace natural tooth structure and is truly universal. It performs equally as well in anterior applications as it does in posterior ones. With a low shrinkage rate of 2% and high compressive and flexural strengths, Evanesce is ideally suited for the most challenging direct restorative indications."
