Q. Why does there sometimes appear to be fewer matrices in the pack then what is specified?
A. Every SuperCurve matrix is made precisely and exactly. For that reason, they are a perfect fit for each other and can nestle together, and it is possible you will take two without realizing it. To help prevent this, shake or tap the box before selecting a matrix.
Q. Sometimes when I place the V3 Ring on the SuperCurve matrix, the ring and matrix slip up the tooth. How can I prevent that?
A. This is most likely to occur on the buccal of lower molars and lingual of upper molars. If it happens, try placing the ring mesially instead of distally. Otherwise, wedge from both sides with Wave-Wedges or use the hard V-Wedge to secure the matrix. It’s a good idea to push down on the ring immediately after placement while it is still in the forceps to make sure the ring is fully seated on the undercuts, and keep your finger firmly against the matrix tab until you have released the forceps to ensure there is no slippage.
