Dental matrices play a crucial role in restorative dentistry by forming a wall or box around a tooth. This function allows for the accurate placement and containment of filling material, such as composite resins or amalgam, during the restoration process. By providing a defined space, matrices ensure that the restorative material maintains its shape and is adequately supported until it sets or hardens.

The use of matrices is essential for achieving a proper anatomical form and ensuring that the restoration has the appropriate contact with adjacent teeth. This helps to prevent issues such as food impaction and maintains the overall health of the dental structure.

Understanding the function of dental matrices is vital for anyone in dental care, as it directly impacts the success and longevity of restorative procedures. The other options pertain to different functions and tools used in dentistry, but they do not capture the primary role of matrices in supporting the filling material during restoration.
