ROOT CANAL PROCEDURE CASE STUDY NUMBER: 542917
Tooth number 16 has to be removed, tooth number 17 becomes a key tooth as an abutment for a fixed 17X15 bridge. POST ENDODONTIC PROCEDURE OUTCOME AMALGAM POST AND CORE BUILD UP
FINAL RESTORATION:IN THIS CASE, REPLACING MISSING TOOTH WITH A FIXED BRIDGE IS A VALID ALTERNATIVE TO DENTAL IMPLANT
On many of your x rays I saw amalgam post and core build up. Can you send me some good reference about amalgam post and core since I wasn’t able to find it in modern literature. Thank you.

Thanks Ivan for your comment.
Dental amalgam has a long history of clinical success. Easily manipulated it has a high compressive strength, high tensile strength and a high modulus of elasticity. Amalgam cores do require more force to dislodge than a casted post and it is less destructive of tooth structure. This material is twice as much resistant to fracture than resin-modified glass ionomer and almost 3 times more resistant than composite. Only drawback is potential for tooth discolouration caused by corrosion but, then again, what are the odds of having corrosion happening under a well fitted crown. Despite all these advantages amalgam use is declining world-wide because of environmental issues and presumably safety issues. And this might explain why you have some difficulties in findings modern literature on amalgam. As far as I am concerned I am still using it because I think it is a safe and durable material. I trust the American Dental Association on this. Here is the link to the ADA Statement on dental amalgam: http://www.ada.org/1741.aspx
Hope this is going to help
Thank you Dr Pizem for detailed answer.
I support your opinion about amalgam. I just never used it as a post material. What is the technique you use? Should I prepare the post space as usually and then condense amalgam in this space and make the post and core build up simultaneously? Also, can this restoration replace cast post and core restoration?
Thanks a lot for help!
