The Acero Narrow Complete Crown Kit contains five each of six sizes, from 2 (smallest) to 7 (largest), for all four primary first molars, 120 crowns total, in a convenient organizer tray.
Acero Narrow Crowns were developed to address the challenges of restoring primary first molars with large interproximal caries. Acero Narrow crowns maintain all the desirable traits of our popular XT and 3S molar crowns but with a 12% reduction in mesial-distal width to compensate for the space loss due to mesial drift of the 2nd primary molar.
