No , The fees guides are determined by the dental associations.
You may be thinking of Britain.
You are probably thinking of the NHS, affordable dentistry for the British public. Free at the point of delivery for those on income support, disability benefits, pregnant mums and kids. Everyone else has to contribute 80% of the fee the rest being claimed for by the dental practice/doc from HM Gov( our taxes). This system is being tweaked every few years by various governments, not necessarily for the better.
When I started out as a tech the lab fee was roughly 30% of the overall fee the doc would receive, this isn't the case any more for a whole load of reasons,
1. like you guys across the pond Chinese labs offering crowns for £22 etc
2. For many uk labs this has been an important part of their business and losing that income stream hurt them, so some have tried to compete with the prices that outsourcing offshore offers(undercutting really)
3. Dental Practices are being bought up by large corporates who are making big bucks by keeping the cream of the overall fee for the crown for example, pay the doc a portion of whats left, the knock on effect is that the lab is now getting a smaller chunk of that pie. Probably 15-20% now. These fees are less than they were when I started out 25yrs ago, just crazy.
One corporate formulated a list of approved labs a couple of years ago, but to be on that list we were required to sign a contract but it came with aload of strings attached, effectively they dictate what discounts the labs gives them, whether the lab can raise prices for example. We declined to sign and are not on their approved list. The contract sucked. Thats my tuppence worth.
