Traditional dentures rely on the quantity and quality of the underlying bone for satisfactory support and retention. When there is not enough underlying bone, patients wearing dentures will experience loosening or slipping while speaking and laughing. An over-denture aims to eliminate these problems.
Over-dentures are dentures made to be supported by strong underlying anchors. These anchors can be your natural roots or dental implants.
Nowadays, dental implants are increasingly becoming the anchor of choice because of their long-term success and reliability. An implant supported over-denture is highly maintainable and can be very comfortable to wear, because it sits securely on the gum whilst still removable for cleaning.
