There are two versions of QuickConnect Anatomy Bands – regular and tabbed. The regular version has no tabs on the top edge of the band.
Creating nice tight contacts on large multi-surface composites has always been challenging and one of the main causes of poor contacts is that the matrix band pulls away from the adjacent tooth, unbeknown to the clinician.
The tabbed QuickConnect Anatomy Band has special “Tight-Contact-Tabs” that are pulled with a dental probe while light-curing to ensure the matrix band is in contact with adjacent teeth, guaranteeing tight contacts*. Alternatively, they can be temporarily bonded to the occlusal surfaces of the adjacent teeth using dental bond and flowable. This second option can save valuable time by allowing you to fill and cure both the mesial and distal boxes simultaneously.
