Dr. L. asks:
I am a recent grad and have been placing dental implants for 3 years. Recently, I completed a case where I forgot to torque down the abutment screw completely. Now it is loose! The crown is still cemented tightly to the abutment.
I always had an implant rep help me in the beginning. How do I retrieve this screw and tighten it? Can I approach it like an endo access? I placed Memosil in the top of the abutment just in case I needed access. Will I need a special bur to cut through through the crown? How do I avoid damaging the abutment and even worse, the abutment screw head?
