TLZ crowns are practically indestructible. This fun video will demonstrate a series of tests we conducted at our facility in Cleveland, OH. The crown we tested has been put through tests for many weeks, primarily driving it into solid wood with the force of a hammer. This crown has been hammered by technicians and dentist for weeks without any signs of chipping or breakage.
