title: Clinical and radiologic assessment of possibilities for endosseous implants and osseointegrated prostheses in 55-year-old edentulous subjects.
abstract: To determine how many 55-year-old edentulous subjects were suitable candidates for implant-retained overdentures of fixed implant bridges and how many of them might be interested in such treatment, case histories were reviewed, and clinical and radiologic examinations were performed on 146 subjects (100 women, 46 men) in a medium-sized city in northern Finland. Numbers and lengths of implants required in altogether 16 regions in the upper and lower jaw were evaluated. The commonest implant length was 8 mm in the upper jaw and 16 mm in the lower jaw. Construction of an implant-retained fixed bridge would have been possible in the upper jaw in 121 subjects (83%) and of an overdenture in all lower jaws. Information about the benefits of the treatment is important because, although the percentage of subjects who were suitable candidates for implant-retained prostheses was high, few subjects were aware of or interested in this type of treatment.
