FAQ

What thickness should I choose?
0.035mm is generally more effective for small decays, while 0.050mm suits larger, subgingival restorations and retains shape well.

What's the difference between hard and soft matrices?
Hard matrices are easier to install; soft matrices adapt more easily for contact point formation.

Do I need to specify a type when ordering?
This kit ships as the standard hard 0.050mm type unless a different type is specified.
