Can I get All-on-4 implants if I have enough bone?

Hi Libtech67!I see you're located in Altamonte Springs, FL. I hope you and your family fared well during Hurricane Irma this past week, and it's so nice to see some Florida faces here on RealSelf! Happy to help you out with this.In any situation where an implant is going to be placed, one of the biggest questions to answer first is: does the client have enough bone? This is because in order to place an implant such as All-on-Four, there must be bone structure to anchor the implant onto. Doing so keeps it secure and will give you the natural feeling you're looking for!In your case, you say you have had your teeth removed two years prior -- any time you have teeth removed, you lose bone structure. To make sure that ANY implant placed is secure, this would require some form of 3D imaging that you could ask for during the consultation or when you call an office for more information. Once they have a look at your images, a provider can assess whether or not there is enough support for your All-on-Four implant.Good luck on your dental journey!- Dr. Patty's Dental Boutique & Spa

Although this might seems in the beginning counterintuitive but if the bone is reduced surgically you can have all on 4 implants with simultaneous loading with a denture. I am not sure if you have currently some teeth or completely edentulous. 
In my experience these cases require good coordination between the restorative team and the Oral and Maxillofacial surgeon to make sure you results are satisfactory.
