I wanted to reach out and ask, if anyone has ever had a healing abutment “cold weld” and be unable to remove it with both a hex driver and/or a torque wrench with the hex driver? I have a healing abutment that has cold welded to a Camlog 3.8mm implant, placed in #19 site 2 months prior. I used 10Ncm to tighten the healing abutment at the time of implant placement with a hex driver and torque wrench. I was unable to loosen the healing abutment with a hex driver and torque wrench. I have even tried vibrating it with an ultrasonic tip. Any recommendations on how I might be able to loosen the healing abutment? I really do not want to explant the implant with trephines and replace it. Thank you.
