I have had dentures for 14 years, I am 36 years old, can I still be a candidate for implants?

At 36 years old you are an excellent canidate for dental implants.  The only way to preserve your bone is with dental implants.  If there has already been too much bone loss you may require some bone grafting.In the upper arch this is usually done with sinus grafts.  More important than are you a canidate is what type of implant restoration do you desire and what is the best way to accomplish your goalThe upper and lower dentures present unique differences and also opportunities.  The use of a snap-in denture allows you to quickly and easily move from a floppy lower denture to a solid cofortable denture.The mini dental implants may let you accomplish this in a single visit.When I have patients who want a quick fix mini implants are ideal.  I often place several implants and mini implants simultaneously so the patient has instant gratification with a solid comfortable denture and simultaneously begin a longer process of reconstruction.Regular dental implnants can also be used for a snap-in denture but have the ability to be used to create and implant supported denture instead of an implant retained denture.You will find a lot of advertising by companies offering all on four implant reconstruction which has advantages and disadvantages.  I usually recomend that all patients get a second or third opinion before preceding with an all on four reconstruction.  It is not usually my first choice of restorations but it is ideal for some patients.At 36 years old you should definitely condider getting implants to prevent excessive implants than can leave you in misery as you get older.

Despite having had dentures for 14 years there is likely enough bone to place implants in order to replace them (dentures). Find a dentist who uses CBCT technology (radiology) when placing implants to determine if there is enough bone and if there is they can then place the implants using a computer guided stent. 

The answer is yes.  How involved it would be and all the options you might have would require a thorough examination and most likely a 3D scan to accurately evaluate the available bone you have left to support implants.  Implant supported dentures are vastly superior to traditional dentures so I would encourage you to seek a consultation.
