Implant-supported complete dentures are a type of dental prosthesis that is designed to replace all of the missing teeth in an arch (either upper or lower) with the help of dental implants. Dental implants are small titanium posts that are surgically inserted into the jawbone and act as artificial tooth roots.

Implant-supported complete dentures are usually recommended for people who have lost all of their teeth in one or both arches and want a more stable and secure solution compared to traditional dentures that rely on suction and adhesive to stay in place.

There are two types of implant-supported complete dentures:

1. Bar-retained dentures: In this type, a thin metal bar is attached to the implants, and the denture is then attached to the bar with clips or other attachments.

2. Ball-retained dentures: In this type, each implant has a ball-shaped attachment that fits into a socket on the denture.

Implant-supported complete dentures offer several benefits over traditional dentures, including improved stability, comfort, and the ability to eat and speak more easily. They can also help prevent bone loss in the jaw and maintain the shape and structure of the face.
