Broke part of the internal hex
I have an implant that was placed 18 years ago top front tooth # 9. About two years ago I bend the screw holding the abutment to the implant and broke part of the internal hex in the implant. Is there a custom abutment and screw that can be made to take care of this problem or do I need to have the implant replaced?
My dentist and oral surgeon belive the only way to fix the problem is replace the implant and start over, the implant is not loose in the bone.
