I do not want an over denture or an implant supported denture.
I typically place 6-8 implants for the upper arch for 12 teeth. At my webpage there are several examples of implant bridges that I have done. The appearance of the prosthesis will depend on the amount of bone you have left and the position of your lips when you smile. This is determined during your consultation. The upper teeth are usually cemented like an ordinary bridge and feel very similar. 4 implants are what some doctors have done but I prefer 6 as a minimum.
