A proposed radiographic index for assessment of the current status of osseointegration.
The longevity of an osseointegrated implant is directly affected by the maintenance of its osseous anchorage. Progressive marginal bone loss would be detrimental to its survival. This article proposes a new radiographic index for use in the radiographic assessment of peri-implant marginal bone levels. The index scores range from 0 to 6 and denote marginal bone loss in percentages relative to the implant body length measured from its coronal-most margin in an apical direction. The proposed index should be of significance in: (1) use of short implants (7 to 10 mm); (2) evaluation of implants functioning in areas of low bone density (types 3 and 4); (3) prognosis and treatment of ailing/failing implants; (4) follow-up of implants placed in extraction sites; and (5) correlation of crown-to-implant ratio with marginal bone loss.
