Implant placement: The dental implants, which resemble small screws made of titanium, are surgically placed in the jawbone. In effect, a dental implant replaces the tooth's natural root. Each implant is inserted into the gums and jawbone through a small incision. One of the advantages of implant-supported dentures is that fewer implants can be placed than teeth. For complete upper dentures, between six and eight implants are placed. For complete lower dentures, four to five implants are placed. After the implants have been placed, the gums and bone will take three to six months to grown in around the implant, a process called osseointegration.
An overdenture is a removable dental prosthesis that covers and rests on one or more remaining tooth roots. A removable partial denture is a dental prosthesis that replaces some teeth and is built around existing natural teeth. Both the overdenture and the removable partial denture may be connected to the remaining tooth roots or remaining natural teeth with anchors made of metal or plastic. These connections improve stability and the retention of both prostheses.
