What is different about your 3D rings than other V-style rings?
Only 3D rings are designed with a firm core that directs the ring tension interproximally where it produces more separation. Only 3D rings have soft silicone on the face of the tines to “hug” the matrix band to the tooth. Flash is virtually eliminated. And only 3DXR and 3D Fusion rings are designed to tenaciously grip virtually any tooth preventing ring “spring-off”.
