Implant supported overdentures are the
next step in comfort over the implant retained dentures. Additional
implants are required for the extra support–-usally 4 to 5 in the lower
jaw and 5 to 6 in the upper jaw. There are several major advantages:
The bone support is maintained in the back area of the mouth
The denture is supported entirely by the implant allowing much greater tissue comfort and retention.
Biting efficiency is now almost like “normal teeth.”
