Amazing case! These are the latest technology, Noritaki full zirconium crowns. Very strong with life-like translucency, the best of both worlds. Double the strength of porcelain, but just as pretty. This patient's teeth were so badly decayed, they were told by the previous dentist (that kept slapping bonding on the front surfaces) to have all their remaining teeth removed and have implants. Distraught, the patient was referred by a relative to me to see if they could be saved. As you can see in the before photo, the backs of her upper front teeth were badly decayed and were caked in plaque, but no one taught this patient how to properly take care of themselves with good oral hygiene technique. Patient was placed in temporary crowns for 2 years to see if the "prototype" crowns could be maintained by the patient before going into the expense of final crowns you see in the after photo. Patient could not stop smiling!
