At first, I was skeptical trying another ring and matrix system from Reinvent Dental Products. What’s so special about the NiTin sectional matrix system? Well for one thing, adaptation to the teeth seems to be quite consistent and doesn’t shift as easily compared to other rings.
The NiTin rings are made of Nitinol, a nickel-titanium shape memory alloy that is stronger than stainless steel and maintains its original shape much longer. The unique anatomy of the tips keep the rings adapted and in place very well. The ring is reinforced with PEEK, a polyether ether ketone that adds strength to minimize the ring movement as well as minimizes sliding out of position too easily.
The tips are anatomically shaped to adapt to the bands better than most rings, thereby preventing excess flash more common with other systems. The NiTin stays more stable, and it prevents the collapse of bands, important to the ease and predictability we all desire. They also can stack well to allow multiple restorations to be done at once.
Why do we need another ring system in our practice? Simply put, 40 to 50 percent of the average restorative practice is comprised of class II restorations. Again, because not all teeth positions, anatomies, and preparations are equal, if you’ve been working with only one system, I’d say you’re missing out. This one is definitely a winner. Add it to your arsenal and make your life easier and more predictable.
