Endo surgery saving prosthesis (by Ilya Mer)

Endo surgery can be always considered as an option in case of good prosthesis that patient satisfied with. This is the case is exactly showing that. Cantilever bridge of #21 and pontic of #11 survived for 9 years and I saw no reason why not to continue to do it further. Surgery versus NS ReTx was definitely¬†questionable. My first treatment option suggestion for the patient was removal the bridge and NSReTx but she has decided to go surgically in order to save the prosthesis. It sounds controversially to do surgery on tooth with open margin prosthesis (hypothetically leakage) and bad obturation quality (hypothetically all root space infected), isn’t it? Any way that the decision was made.

Not always easy to neither  cut silver point nor retrieve it thru the apex. I was walking around the silver with ultrasonic 5mm tip and cleaned the root for retrofilling.
