Having dentures for such a length of time, does not stop you from being successfully treated with dental implants. There are new implant technologies, such as 'Zygoma' implants that mean patients with considerable bone shrinkage in the upper jaw (caused by missing teeth for long periods of time) can be treated and rehabilitated with fixed, implant supported teeth with no grafting required. In the lower jaw, this is also the case, with shorter implant lengths and improved surface technologies. Best of all - in many cases this can be achieved with an immediate function situation - meaning implants are placed, and teeth attached to the implants within a matter of days. 45 years of dentures - to fixed teeth in less than a week!
