Practical How To Supporting Your Practice

Practical How To: Composi-Tight Sectional Matrix System


This post was prepared in collaboration with Garrison Dental

On an experimental basis, we have asked a limited number of companies to provide us with practical “How To” answers to clinical questions. We were prompted to conduct this experiment when dental team members told us that they visit company websites and consult company representatives for practical clinical information. We look forward to receiving your feedback on this experiment.


Like many entrepreneurial businesses in America, Garrison® Dental Solutions started in a basement – the basement of Dr. Edgar and Dr. John Garrison’s dental practice. This was the rebirth of the original Composi-Tight® Sectional Matrix system in 1996. Many years and several hundred million matrix bands later, the same energy, enthusiasm is still driving our innovation.

Garrison’s new Composi-Tight® 3D Fusion™ sectional matrix system was designed based on feedback from users worldwide and over 20 years of proven sectional matrix leadership. This has translated into a new system that represents a significant improvement in usability and performance.


The kit contains 3 rings. The short (blue) and tall (orange) rings are used for the majority of restorations. Whereas, the all-new wide preparation separator ring (green) allows for versatility and makes the system even more user-friendly. The wide prep ring helps clinicians meet the challenges of large posterior composite restorations so that the achievement of excellent contacts and contours is commonplace, even when a cusp is missing.  

All the rings have a new “horseshoe” shape which is easier to open.  In addition, the all-new design provides 20% more separation between teeth resulting in better proximal contacts in the final restoration. The gingival aspect of the separator rings also have a unique design which sits on top of the interproximal wedge without displacing it.

How does Composi-Tight® 3D Fusion™ accomplish this?

  1. 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 they are placed.
  2. Stack it up – Tru-Stack™ technology allows placement of the tall ring (orange) over the short ring (blue) for easier MOD and multiple tooth restorations.
  3. Hug the curves – Soft-Face™ silicone tips with enhanced marginal ridge anatomy create a tight hug between the matrix band This virtually eliminates any flash.
  4. Keeps on going – Enhanced durability for extended ring life and greater tooth separation.
