| The Composi-Tight 3D Sectional Matrix System is designed to create tight, anatomical contacts on Class II composite restorations. The contoured sectional matrix bands create proper tooth anatomy while two styles of rings create the required tooth separation and band adaptation for a tight, natural contact.
The orange Soft Face 3D-Ring will be the ring used in most circumstances because of its ease of placement and its ability to adapt to a wide variety of tooth anatomies while reducing flash and restoring proper contour. thin tine G-Ring.
The thin tine G-Ring (gray) is utilized in certain conditions where the shape of the dentition will not allow the contoured shape of the Soft Face 3D-Ring (orange) to grip tightly around the tooth, such as the distal of a canine. In this condition, the burnished ends of the thin tine G-Ring will adapt and retain more effectively. The thin tine G-Ring may also be preferred for malpositioned or pedodontic applications. A firm core in the center of each soft, adaptable tip directs the ring’s tension interproximally where it is most effective for the separation of teeth. Other V-shaped rings push more on the sides of the teeth. Three-dimensionally contoured tips with Soft Face adaptable silicone hug the matrix band to the tooth. Flash is virtually eliminated greatly reducing finishing time. No sectional system seals better or produces more anatomically accurate restorations. The tips of the new Soft-Face 3D-Ring are wider than standard separator rings allowing placement on wider embrasures.
The slotted bottom fits directly over the wedge simplifying placement and allowing for wedge adjustment. The reinforcing overmold enhances ring tension and longevity giving you maximum separation that lasts restoration after restoration. Both styles of 3D system rings are fully autoclavable. Both the Composi-Tight 3D Soft-Face Ring (orange) and the thin tine G-Ring (gray) are angled at 12.5º to allow stacking of rings for performing M.O.D.s and multiple-tooth restorations. Either ring may be stacked over the other, and in any combination.
