Last month I did a case involving a pfz crown on top of a zirconia abutment with ti base. It was not cemented until this morning and now I got a call that the porcelain chipped on the incisal edge. 3 hours after the patient left the office. The incisal was thin because the patient insisted on it The dentist used permanent cement and can't remove the crown without destroying it. He's going to remove it by drilling an access hole on the lingual of the crown and remove it as if it was a screw retained case.
Any ideas on how I can remove the pfz crown from the zirconia abutment? Anybody try baking porcelain to a ti base zirconia abutment in the furnace? I'm guessing the adhesive holding the zirconia abutment to the ti base would come out. I'm just thinking what I could do to avoid remaking this case.
