All teeth are missing in the treatment plan. When a patient is missing all of their teeth, traditional removable teeth feel significantly foreign, fall out easily and chew less efficiently. The best treatment option is to have dental implants. Compared with traditional removable denture, full dental implant can avoid the problem of progressive atrophy of alveolar bone, and dental implant is foreign body free, stable and comfortable, and more functional to restore chewing function. There are two types of full mouth dental implants: 1. Multiple dental implants are placed as abutment posts to allow 2 to 4 dental implants to hold the implant overdenture (implant removable denture). 2. Implantation of multiple dental implants as abutment posts for the retention of more than 6 dental implants to create a fixed denture. What is the restoration method for missing teeth in the whole mouth? In general, it includes implantation of removable teeth and implantation of fixed teeth. Fixed dental implants generally require more than 6 implants to provide adequate support for a full denture for segmental restoration. Implant-retained dentures are full dentures that use implants: a small number of implants are placed on the upper and lower jaws, and the implants are connected to the full denture using ball caps, bar clips or magnetic retainers to provide greater retention and stability, which significantly improves chewing performance. The integration of dental implants with traditional complete dentures strengthens the retention and stability of complete dentures, solving the problems of easy loss and poor chewing efficiency of traditional complete dentures.
