Fixed implant retained dentures require more implants than a removable implant retained denture because the denture is permanently affixed onto the implants and requires greater stabilization. Implant retained dentures feel much more natural than removable dentures and chewing efficiency is completely restored.

Removable implant retained dentures require fewer implants; Four dental implants securely hold an upper denture allowing the size of the plate to be reduced or eliminated from the denture altogether. Plate reduction or elimination feels more natural and allows for the better tasting of food. Just two implants under a lower denture can improve stability and restore chewing efficiency up to 90% of normal. Four implants provide up to 100% normal chewing efficiency. Removable dentures also allow for easier maintenance and cleaning.
