The Sectional matrix has revolutionized posterior composites by providing a 3D-curved shape that circumferential bands cannot match. Using a Sectional matrix allows for a natural emergence profile and a contact point located in the middle third of the crown. For dentists in Egypt looking to move away from "flat" contacts, the sectional matrix materials are the gold standard for restoring the proximal anatomy of premolars and molars. Our collection includes trusted brands and durable dental matrix materials designed for consistent, high-quality clinical results.
How to Choose a Sectional Matrix Based on Cavity Size
-
Vertical Height: Maintain a range of sizes from 3.5mm (for pediatric cases) to 6.5mm (for deep subgingival molars).
-
Cervical Extension: Choose bands with a cervical "tab" to ensure the matrix sits deeper in the sulcus, effectively preventing overhangs.
-
Occlusal Grasping Tab: Look for a tab on the top edge to allow for easy placement and removal with tweezers while preventing metal distortion.
