METHODSAbutment tooth canals were firstly prepared according to respective canal directions and then complete crown preparation was made following standard procedures. The impression of prepared abutment teeth was taken with silicone and specially made syringe. The fixed partial denture and bolt-like post were fabricated respectively and lastly the two parts were glued together in patient after try-in.
RESULTSAll the fixed partial denture with the new post-core system did not get loose and there was no abutment tooth fractured after 23 months in use.
