Matrix systems are essential tools in restorative dentistry, used to create temporary walls around a tooth during composite or amalgam fillings. They help shape and contour restorations, ensuring proper contact points and a natural tooth form. These systems prevent excess material from spreading beyond the cavity and aid in achieving smooth, well-adapted restorations.There are various types of matrix systems, including sectional, circumferential, and tofflemire-style matrices. Sectional matrices, paired with rings, provide better adaptation for Class II restorations, while circumferential matrices are commonly used for larger restorations. The choice of system depends on the type and location of the cavity being restored. Matrix bands are typically made of stainless steel or transparent plastic, allowing flexibility in different procedures. Proper placement and stabilization ensure an accurate restoration with minimal finishing adjustments.
