I disagree charles, I think more Drs ARE doing (or trying) these type of bridges... and anyone with a 5 axis mill, thinks they can manufacture them. GW will get more and more of these cases, because thats just what GW does, suck up market share with rock bottom pricing. GW can remake the case almost 3x before a Dr pays another lab for the 'same' bridge..
Here in spokane, the leading prosthodontist charges over $50k for these, per arch. A lot of other Drs think they can offer the same treatment, because they can place 4 implants!
I had a Dr, quote a pt. $10k for this treatment, (his charge).. when I told him it would be over $5k for the bridge, he didnt know what to think. Of course he gave the pt the estimate (and placed implants) before ever consulting with any lab on what the fee would be on a case like this. No plan=no bueno. No concept of what is involved. Never even asked what would be involved. Some Drs think they can just take an impression and a bridge will magically appear. No concern of placement, tissue management, VDO, bite verification. In fact VDO was never even discussed, who knows if there is even room for a case like this.. ugh end rant.
