Dental Crown Material

3M Lava Ultimate Crown Material

3M is paying $32.5 million to settle a class action brought against it by a group of dentists and dental practices. The complaint alleged that 3M’s ESPE Lava Ultimate CAD/CAM Restorative blocks, when made into dental crowns, had a much higher rate of debonding than other crowns, due to the materials of the Lava Ultimate crowns.
