Matrix Rings

The two main separator rings, short (blue) and tall (orange), are the heart of the new Composi-Tight® 3D Fusion™ system. These are your “go-to” rings and will be used for the majority of restorations. The short ring is mainly used for bicuspids, premolars, pedo, malpositioned teeth; any tooth with a short crown. The tall ring is used for typical molars, taller teeth, or stacking over blue for MODs.

The world’s first Wide Preparation separator ring (green) makes Composi-Tight® 3D Fusion™ the most versatile and user-friendly sectional matrix system available. The Wide Prep ring greatly simplifies what until now has been one of the most challenging posterior composite restorations. Now you can restore extremely wide preps and missing cusps with confidence knowing that you will achieve excellent contact and contour without having to take extra steps.

• Get a grip –  All Composi-Tight® 3D Fusion™ separator rings incorporate Ultra-Grip™ retention extensions that anchor them securely to virtually any tooth. Fusion rings stay where you place them!
• Stack it up – Tru-Stack™ technology allows placement of the orange ring (tall) over the blue ring (short) for easier MOD and multiple tooth restorations
• Hugs the curves – Soft-Face™ silicone tips with enhanced marginal ridge anatomy hug the matrix band to the tooth for flash free restorations
• It just keeps going – Enhanced durability for extended ring life and greater tooth separation
