We set up for this “Zirconia Hammer Test” using a KDZ Bruxer Solid Zirconia Crown, a pine wood wedge and a PFM (porcelain fused to metal crown). Dr. Hornbrook grabs a PFM porcelain fused to metal crown and a KDZ Bruxer Zirconia crown from the Dental Lab Floor at Keating Dental Lab to test the durability and flexural strength using a very common older method of testing. “THE HAMMER”. Not sure what else you could use, but this test really nails it down “literally”!
See why the KDZ BRUXER and its flexural strength of 1600 is the obvious choice for crown restorations compared to the PFM (100 Flexural)!
