It isn't so much a function of the cost of the parts, I don't see those coming down as the margins are not that great for manufacturer's now given the FDA compliance and regulatory issues that are part of their selling costs. So this is largely a doctor's fees issue, and with the escalating insurance costs to do business and other realities of practice, I also do not see relief in the future there. The only thing that could change the world of dental implants is 3rd party payment, which for the non cancer group isn't going to happen in the near future.
