I find it challenging to place sectional matrix bands, so much so that sometimes I just reach for a good old fashioned toffelmire, even though I know that adaptation and reproducing anatomic form is superior with the sectional. There are two pieces that frustrate me. The first one is how to hold on to those little pieces of metal, and secondly getting them in the right place and feeling like I have good control during placement.
I had the opportunity to watch my dental partner place a sectional matrix today, and it was eye opening. He reached for a pair of cotton pliers which are standard issue on our tray set-ups. He kept looking right past them, and then requested a pair of the straight tip cotton pliers. He explained that they grip better and make it easier to hold the sectional matrices, this was my first learning moment. Then I watched as he bent the corner of the matrix, explaining that it can be difficult to place the matrix. It is difficult to get your hand at the correct angle in order to place it in the contact, so he “dog ear’s” the corner of the matrix and creates a handle that allows him to grip it firmly, and place without contorting his wrist.
As it worked out I had a class two composite on my schedule later and got to try out my new learning. Both tips work perfectly, and made all the difference in using a sectional matrix band. One of the things I value everyday is the little things we can learn from watching each other work.
did you try Triodent ? They all tend to bounce back up, even with a wedge but they are wonderfull !!
Pierre, I have not tried this system, but I will and I’ll let you know how it goes.
How about a YouTube to show the process?

Great idea. I just started doing some video blogs this week. I think this would be a great one so I have added it to the production list.
Have you tried the Garrison Dental Composi-Tight 3D Matrix System? I am thinking about getting that systems.
I use the Garrison system routinely and really love it.
Hi Lee Ann, What do you recommend for technique to take OUT the matrix?? I tend to have to jiggle it out and sometimes cut the tissue that it was so well adapted to. Then it’s no fun to trim! Thank you and love the new website :) Hope all’s well!
Hi Lee Ann, I’ve become a BIG fan of your site and love the big and small tips and tricks I’m learning here!
In response to Amelia’s request for suggestions on removing a sectional matrix, I thought I’d offer my technique. I use 2 sets of locking hemostats. Mine are curved but the straight ones might work well too. I hold one set in each hand and lock them onto either edge of the matix band. Then I slowly ‘see saw’ the band until it releases….I’ve yet to have this fail so hope it’s a help to others.
Vivian, I love the see saw idea, I’m trying that on the very next one. I usually use a locking hemostat and simply tease the matrix out of the contact slowly.
To further add to the discussion about removing the matrix band I thought I would contribute what I do. As Lee mentioned the standard cotton pliers are not very helpful because the grip strength is too weak, so I grab the matrix band at the “dog ear” where the extra thickness gives you a little more strength to the matrix band. I use the same straight tip cotton pliers and instead oof pulling, I turn my hand while holding on to the matrix. This rotates the band out with a great deal of ease and very little tissue damage.
Thanks Scott, this is great and I will try it. Also, thanks for showing me how you put the sectional matrices in, and dog ear them.
Hello Scott, would you mind showing us a video of how you do that, the part about moving your hand to take the matrix out
Hi Lee!
Late to finally check out the site but it is wonderful! I used to use a slim weingart ortho plier to remove the matrix, but we’ve now switched to the Triodent system and love it. The forceps and pliers that come with the kit are wonderful for placement and removal. Each matrix has a hole punched in both ends and the tab that is used to place it. The pliers fit into these holes perfectly with no problems removing them.
Hope you’re having a great week!
Hi Allyson, hope you are doing GREAT!!! Thanks, I have heard good things about this system, and now I have a better sense of how it works and why folks like it. I will definitely get some to try. I may be coming to SC next year to speak, so maybe we can get together.
Hi Lee, with Garrison rings and with lots of work around it, I still get composite ledges on side walls of the box. The sectional piece always has a gap and i cant get it right.how you adapt?
If I need to I customize with teflon tape to make sure the band is snug against the walls of the prep.
