I am considering implants to replace a lower denture, but I'm not sure how many I need. Some have had only two implants that are working fine for them. Others have had 4 implants that also work well. How do I know which would be best for me. I am 91 years old. I have worn a full upper denture and a lower partial with 6 center teeth remaining for many years. I have now had these six teeth extracted and must decide whether to have implants. My dentist is willing to make a complete set of dentures to see if they will stay in. He said he would be able to use these dentures if it is necessary to have implants. There is a large difference in cost between two implants and four implants. Would 2 implants work for me?
There is no bad choice, especially if you have been wearing a lower partial denture for a number of years. Both options will be great.
The two implant option will give you a level of stability to your lower denture that you haven't enjoyed in years; however, there will be a small degree of "rock" in the denture, as the two implants will act as an axis about which the denture can can rotate slightly. The four-implant option will give you stability with virtually no "rock" of the denture.
I have been using the two implant option for more than 20 years. I always tell patients they can have additional implants placed if two aren't sufficient. Not one patient has asked for additional implants.
Lastly, my father-in-law, who is also 91, lost his last few teeth in the spring. I utilized the two implant option for him.
