More than 20 years of sectional matrix leadership and an incredible amount of feedback from users all over the globe were poured into the design of the new Composi-Tight® 3D Fusion rings. All this hard work has resulted in separator rings with significantly improved performance and ease of use.

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 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 these big preps 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
