Check out sites like implantinfo.com & implantforum.com for general info on implants. Most surgeons have a finance plan of some sort. I would recommend talking to at least a few doctors - make sure to get good solid references preferably from someone who has had surgery w/ them - or there are some that are recommended on the sites I listed. But go & talk to them - often there's a consultation fee of $50 or something so I guess you need to be judicious in talking w/ different surgeons but you need to be 1) comfortable w/ the doc, 2) trust the doc, 3) get good referrals for the guy & 4) do a solid background check on him as far as malpractice claims, etc. (this is all discussed on implantinfo.com).
But whe you talk to them, they can tell you prices & payment options. It is a surgery and you need to pay attention to who the surgeon is and what you should expect - take the same level of precaution in locating a suitable doc just as you would for any other invasive procedure.
