Garrison Composi-Tight® 3D Fusion® Evaluation Complete

For over a month now, I’ve been working with the newest sectional matrix system from Garrison.
 
The system, which Garrison calls the Composi-Tight® 3D Fusion® is a complete and well thought out restorative system.  It has performed extremely well in a variety of clinical situations.
 
Rings
It consists of different rings (Short, Tall, and Wide Prep).  The rings, as pictured above, have strong gripping silicone covers over the tines.  These silicone grippers (Garrison calls them Ultra-Grip™ retention extensions) are pointed, which allows the ring to better conform the band to the prep as well as providing good pressure to open the contact area.  There is also a notch on the gingival surface that allows the ring to “straddle” the wedge so that the wedge stays in place and does the job it is designed to do.  They also are curved in an occlusal-cervical direction to better engage the anatomical curvature of the tooth.  This allows them to truly lock into place and grip the tooth and band with firm and stable pressure.  You can see this curvature in the photo below.

Wedges
Companies have tried several different versions of silicone wedges over the years and all the designs have worked better than the original wooden wedge, but Garrison has come up with a unique and well thought out idea, the “feather wedge”.  I have to admit that when I first saw them, I thought they would perform poorly… but I was wrong.  The small projections on these wedges allow them to effectively seal the band against the cervical of the prep.  They are also remarkably easy to place and, once placed, stay firmly between the teeth.  They come in four sizes as shown below:

Forceps
The system also comes with Ring Placement Forceps which are extremely sturdy and feature a Garrison logo open stop.  These forceps are made of stainless steel, which makes them incredibly strong and able to provide a significant amount of strength when opening rings.  Many of the forceps I’ve used over the years are not made of stainless steel and flex when opening the ring.  The flexure means less pressure is applied to the ring which translates into a ring that will not open as far.  These forceps might just be the best ones I’ve ever used in restorative dentistry.  They are designed to work with other types of rings so if you happen to use more than one system in your office the assistant is not forced to find the exact forceps that works with whatever ring system is being laid out.  This “one size fits all” design helps streamline organization and operative setups.
 
My hands require a large glove and both of my assistants wear small gloves.  However, we all felt that the forceps fit our hands well.  I can say with confidence that no matter your hand size, you will find these forceps comfortable and easy to use.

Conclusion
After a month of usage, I’ve found the Composi-Tight® 3D Fusion® to be reliable for any Class II restoration.  I have had NO open contacts, minimal flash, and very nice contours.  I’ve had no rings slip off teeth and the rings are easy to place.  I’m especially impressed with the wedges, especially since at first glance I was not sure how well they would work.
 
My overall impressions are that this is a first rate product for anyone looking to improve their Class II restorations.  This product is highly recommended!!!
