Only 3D rings are designed with a firm core that directs the ring tension interproximally where it produces more separation. Only 3D rings have soft silicone on the face of the tines to “hug” the matrix band to the tooth. Flash is virtually eliminated. And only 3DXR and 3D Fusion rings are designed to tenaciously grip virtually any tooth preventing ring “spring-off”.
We strongly recommend that you use Garrison ring placement forceps. They are specially designed to open our rings and for ease of use. Rubber dam forceps do not fit the rings well and you will not be able to open the ring wide enough in many cases.
Providing “pre-separation” will help. The preferred method is to use a Garrison FenderWedge during tooth preparation. The FenderWedge will start to separate the teeth while your are cutting the preparation. When the prep is complete, remove the FenderWedge and immediately place the matrix band. Using a traditional wedge for pre-separation will also work, but it will not protect the adjacent tooth from accidental burr contact.
Alternatively, placement of a G-Ring or 3D ring on the tooth for a few minutes prior to matrix band placement will also produce separation. After the ring has been in place for a few minutes, remove the ring and immediately place the matrix band.
Composi-Tight matrix bands can be burnished further than a traditional matrix, but if the distance is too far you will need to employ one of the larger, wider matrices.
It is the combination of the separating force produced by both the ring and the wedge that stretches the periodontal ligament. Reducing the size of the wedge will lighten the contacts. Contacts that are too tight can be lightened with the use of a fine diamond finishing strip.
Use of SlickBands or SlickBands XR with their non-stick coating will greatly simplify matrix band removal. Additionally, our Matrix Forceps with their carbide teeth, provide excellent grip on ultra-thin matrices for easier removal.
"This new modification of the ring makes a lot of sense, and since some newer ring designs allow for better wedge placement, this new design offers two benefits – allows the placement of the wedge and the ring over top of it more easily, and the interproximal extension provides better separating force while adapting the matrix creating less flash and less work for the dentist in finishing class II composites. It is a definite step in the right direction."
"Adjusted areas polished with the two eZr grits look like smooth glass when examined using my 4.5x loupes!"
"We produced the margin elevation band to facilitate the deep margin elevation technique which is becoming increasingly popular with adhesive dentistry. Properly performed, this technique allows for a conservative indirect restoration to be completed without additional invasive treatments. The use of this band and unique matrix shape allows the band to form a tight seal in deeper cervical areas where other bands would usually be unable to reach."

"Garrison are experts at innovation and finding solutions for our patients. Their Composi-Tight 3D sectional matrix system is a perfect example of this. They place significant focus in designing and developing instruments to perfect Class II restorations, which gives me absolute trust in their products and they continue to surpass other kits on the market.
I have used their 3D system since it was launched, which offers an impressive combination of clever design, simplicity and technique to help create correctly shaped restorations that one can see time and time again. The tooth, the periodontal tissues and the clinician all benefit in achieving sealed, tightly bound proximal contour and contacts. It is an essential piece of kit that every clinician should have. The A+Wedge is their latest addition to their portfolio and complements the sectional matrix system in a predictable way."

"All I can say about the new products is "Incredible"! The new matrix bands are much easier to place and the longer length enables me to use them effectively to restore wide embrasures. The new Composi-Tight Gold retaining rings are far superior to anything I have ever used and, with the increased tension, provide the tightest contacts we have ever gotten on a consistent, predictable basis. I also love the new tip design of the ring placement forceps. It is a vast improvement over any other I have used, making placement a snap. Once again, Garrison Dental has raised the bar to a new level!"

"The 3DXR ring from Garrison Dental is a significant improvement on all previous rings; it is truly universal and I have not found any Class II restoration that it will not fit. The 3DXR has not flown across the room once! When used with the sectional matrices and WedgeWands (or A+Wedges), it helps to provide a tight anatomical contact area and highly predictable posterior composite restorations every time."
