An implant-supported denture is a type of overdenture that is supported by and attached to implants. A regular denture rests on the gums, and is not supported by implants. An implant-supported denture is used when a person doesn”t have any teeth in the jaw, but has enough bone in the jaw to support implants. An implant-supported denture has special attachments that snap onto attachments on the implants. Implant-supported dentures usually are made for the lower jaw because regular dentures tend to be less stable there. However these provide a great support and allow for proper utilization of both upper and lower implants.
