Which term refers to a matrix used in restorative dentistry alongside traditional methods?

• A. Siqveland matrix
• B. Tofflemire matrix
• C. Sectional matrix
• D. Wedges

Answer: (A)

In restorative dentistry, achieving a accurate proximal contact and contour often requires more than a single traditional matrix system. The Siqveland matrix is a specialized proximal matrix designed to be used alongside conventional methods, providing stable support for the proximal wall and helping recreate a proper contact during class II restorations. Its design works in conjunction with standard tools like retainers and matrix bands, and is especially useful in challenging cases where the ordinary matrix alone may not produce the ideal contact. Wedges may still be used to seal margins, but the matrix itself is what shapes and stabilizes the proximal aspect, which is why this term describes a matrix used in addition to traditional methods.
