Characteristics of overdenture implants These are the most economical option for attaching dentures in a mouth that does not have enough support. Overdentures are retained in the mouth thanks to their anchorage to the implants and to mucous support (the alveolar crest). The anchors can be bolus, locator or rod type. These anchors hold the prosthesis to the implants.
The number of implants required for the overdenture will be determined by the specialist, but the minimum upper arch will be four and the lower arch may be two to four.
