Why use a Sectional Matrix System for class II fillings? Tofflemire-style System Fails to restore proximal anatomy Thin contact at the marginal ridge Large food trap below Increased likelihood of fracture, occlusal interference, recurrent caries and periodontal disease Strata-G ™ Sectional Matrix System + Rings produce optimal tooth separation for excellent, tight contacts + Bands with pronounced curvature for anatomically correct contacts + Contacts at the height of contour + Operator-friendly retaining system + No post-processing necessary + 26 years of experience in sectional matrix systems combined in the Strata-G ™ sectional matrix system 1 Insert the matrix band: Totally soft (dead soft) three- dimensionally rounded matrices have protrusions to grip for easy placement, and Garrison’s revolutionary non-stick surface 2 treatment for easy removal. 2 Wedge tight: The universal wedges slide into place easily and won’t back out. Their soft, flexible outer surface easily adapts to unevenness between the teeth, and presses the matrix very tightly against the tooth. 3 Place the ring: All three Strata-G ™ rings fit over the wedges for easy placement. Ultra-Grip ™ retention keeps the rings firmly in place, from the distal side of the canine to the largest molar preparations.
