Unable to release porcelain tooth from implant
I have just had porcelain crown put in on implant left back upper jaw. On follow up visit 1 wk later, returned for final check of that all was ok. Dentist wanted to have the crown re-coated after grinding off bite surface (for perfect fit) at initial visit.
He removed screw but was unable to release porcelain tooth from implant surface. His attempts to pull off tooth caused a sensation I can only describe as bone crunching. Will be going for pan X ray to check.
What could cause the tooth's metal to adhere so strongly to the implant's metal surface?
