Hi Mark, You must have done some research about your costs. Implants are expensive and the denture on top may cost you another $10k. You can choose to have several different types of implants ranging from mini-implants, which are far less costly approx $15k or convential as you have been quoted. Please view this page for a beautiful implant denture http://www.e-dental.co.nz/denture_implants.asp .These dentures are difficult to remove and create stability. You will also not need plastic on the roof of your mouth. Taste, speech, and masticatory forces are improved. Please call us if you would like us to do this for you. Sincere regards Michael.
