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.
A film of saliva typically helps hold dentures in place. Denture adhesives may be used if the salivary glands do not produce a sufficient amount of saliva. Denture adhesives are not, however, a remedy for ill-fitting dentures. A denture that fits poorly (i.e., feels loose or causes discomfort) may need to be relined or replaced as it can contribute to the development of mouth sores.
