SlickBands™non-stick matrices are the first Tofflemire-style bands to virtually eliminate the problem of difficult to remove matrix bands. A micro-thin coating bonded to either dead-soft or regular stainless steel reduces bonding agent adhesion by a whopping 92%! The Right-Curve™ matrix band creates a significantly increased funnel-shaped cone when wrapped around a tooth providing a lower contact point and improved isolation: Funnel shape reaches over to the adjacent tooth more easily and creates a tighter gingival seal Creates broader, deeper contacts Extremely wide preps are simplified Improved visibility for core buildups The Margin Elevation matrix will give you the best gingival adaptation and contour for the deep margin areas: Matrix is trimmed in height to allow for improved adaptation to deep margin areas Deep margin elevation technique is a useful non-surgical approach to treating deep localized margins
