An overdenture is a type of removable denture that is anchored to two or more implants. The denture “snaps in”, however can easily be removed by the patient. Often the biggest complaint a patient has about their denture is that “it keeps falling out”. An overdenture is a very cost-effective method of giving additional retention to a denture so that there can be a much more comfortable, hygienic fit with out all of the denture adhesive. This variety of prosthetic is generally used to help retain a lower complete denture, and as few as two implants can be used.
