There are different types of dentures, but they share a common function. They replace missing teeth lost to periodontal disease or decay. The entire mouth is examined and a determination is made as to which teeth will have to be removed and which will remain. The compromised teeth are then extracted. After healing, impressions are taken, and dentures are fitted to go over or around the remaining teeth in the mouth. There is an adjustment period after dentures are placed in the mouth sometimes accompanied with denture sores. Adjustments are made in the denture to relieve the sore areas.

If loose, implants can be used to provide support and retention for a full denture. An implant-supported denture is a type of overdenture that is supported by and attached to implants leaving it more stable than a regular denture that rests on the gums and may be loose and uncomfortable. 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 the implants. Implant-supported dentures usually are made for the lower jaw because regular dentures tend to be less stable there. A non-implant supported denture made to fit an upper jaw is quite stable on its own and doesn’t often need the extra support offered by implants. However, an implant supported denture can be made for the upper or lower jaw.
