#8, 9 restoration

+1 - as long as you give the lab enough room to work with, what i find to be the toughest part of restoring 8/9 with crowns is the shade matching and the proper communication of the shades to the lab.

thanks, also I have an additional question: if there are only 3 remaining sound anterior teeth remaining on the lower, would doing a long span bridge be giving more arch stability than a RPD?
Way to many variables to figure out to answer that one. Need to factor in the location of those teeth, their periodontal stability, the patient's occlussal scheme/habits, etc, etc, etc.
Plus, personally if I'm placing more than a 3 unit bridge, I'm having the lab add a stressbreaker into the bridge to allow for jaw flexion or else you're just asking for an even earlier ultimate failure of that bridge due to premature cement failure.
Obviously that RPD would put some increased wear and tear on those remaining lowers which isn't good. However nowadays, I'm doing my darndest NOT to place any long span fixed restorations in folks mouths and ideally nothing longer than 3 units in my patients mouths (i.e. I'd much rather place 2 or 3 or 4 small bridges in my patients mouth than 1 large bridge if at all possible).
The key I find to treatment planning a big case is to look at it EQUALLY from 2 perspectives 1) what do I need to do to make this case work and 2) what will I be left with WHEN it eventually fails! Often that 2nd part ends up changing your final treatment plan for the better for both the patient and yourself. And if you think that the second part about what to do when it fails isn't a factor, then just wait a few years when your work has had a chance to be used and abused by your patients a bit longer and you'll know what I mean 😱😉
