ABSTRACT: In our previous studies, we developed the normal
periodontal ligament index (nPLI) and residual periodontal ligament index
(rPLI) to estimate residual periodontal ligament support for individual teeth
during treatment planning for partially edentulous patients. To illustrate the
applicability of the nPLI and rPLI, an occlusal-supporting ability (OSA) score
calculated using these indices for the remaining teeth corresponding to
Eichner’s subclasses of partial edentulism was charted by numerically
assessing the average occlusal support. This OSA score based on the nPLI and
rPLI is proposed as a suitable tool for epidemiologic research on the
progression of tooth loss and the survival of prostheses. The Ethics Committee
for Epidemiologic Study of Hiroshima University approved the study protocol
(No. 331).
