I've had full dentures for around 45 years, is it possible to still get implants?

Regardless of how long you have been wearing a denture, nearly anyone can be a candidate for dental implants.It’s very possible that since you have been wearing a denture for an extended period of time, that bone may need to be added back. This procedure is called a bone graft.In addition, since you have been missing back teeth for quite some time,  it is also possible that you may require a different type of graft called a sinus lift.These are all questions that can easily be answered by an experienced implant dentist.I hope you found this information to be helpful,Dr. Champagne

Implant and fixed options are better now than they have ever been. I would get a consultation, 3D xray,  and learn more about what can be done. 

You would need xrays, a 3D scan, and an evaluation to determine if you are a good candidate for implants. Having dentures does not automatically exclude you from having implants.
