LOL:
In retrospect, i believe endo access technics became conservative and cast post almost obsolete. We stopped teaching a cast post in posterior molars and premolars in 1980!!
John... that is a brilliant analogy endo abutment vs implant abutment.
I recall years ago a dental school Chair in Germany would not permit his staff to use teeth with endo as abutments for a bridge.
Then years went by and I was teaching the world about no posts in posterior teeth and there was a huge issue until we did lab research and clinical data that proved they made good abutments. He invited me to come to his Univ and share the info with his Faculty and they started teaching endo molar teeth as abutments for an fpd.

I still favor an implant as an abutment.

OK, what if you have 2 potential bridge abutments (not necessarily 6 and 11, but any bridge) that have endo that looks decent.Seems risky either way. The implant is at some risk due to the endo teeth next door. The bridge is risky due to the endo abutments.Sometimes you can't win.....John Highsmith DDSClyde, NCAACD Accredited DentistLVI Clinical InstructorDiplomate, ICOIFellow, Misch Implant Institute

I would probably recommend that you remove the teeth, place four implants- #6, #8, #10,and #11 and place two mini- implants at #7 and #9, and make an immediate removable partial (flipper) with ERA's on the implants. Let the patient wear this for four months, then engage the implants for impressions and make your fixed bridge with those implants.Of course, you could always just do a immediate partial with transparent clasps. But the endo/buildup/ and fixed bridge method is just fraught with complications and the threat of failure again.RickOn Sun, May 26, 2013 at 11:34 AM, ARUN NAYYAR <arunnayyardmd@gmail.com> wrote:
This morning a patient called and said she had snapped her anterior bridge off at tissue height.He denied any trauma... i think she bit into something hard with enogh force to snap the abutments.
No pulpal exposure!!! on any of the 4 abutmentsShe has 4 abutments, #6,8,10 and 11I made the prosthesis as a part of a recon some 15years ago.She wears a bite guard and is v compliant with 3 m recalls.All the other 22 restorations are doing well at 15 yearsSO here is the QA intelligent patient... well read and does her due diligence.Q1 Do endo on 4 abutment teeth, then posts, surgical crown lengthening and a 6 unit 4 abutment FPDOrQ2: Extract roots, pack bone, do immediate implants placement, immediate or delayed loadingAnd do SIX individual implants /crowns ( with guided surgery )ORQ3 Extract roots, pack bone, do immediate implants placement, immediate or delayed loading
And place THREE or FOUR implants and make a 6 unit splinted prosthesis. ( with guided surgery )Interestingly when we consider 4 endo, surgical cr lengthening, 4 cores + a 6 unit prosthesis over implants. the implants provide a longer clinical life and will be expedient and cost a few more $$As I debate this in my own mind, I reach out to you for inputBiggest Q is that before implants, the only choice was to endo, core and a FPD. Today we have the option of implant supported prosthesisWe also know the ROI and long term value for the patient favors implants4 endo + core + FPD vs 4 implants + FPD. vs 6 implants and 6 individual crownsThank youArun--Arun Nayyar DMD,MS.
