Abstract

A new mandibular positioner for quantitative analysis of mandibular bone resorption by rotational panoramic. radiography enabled measurement of the mandibular corpus height. The purpose of this study was to investigate the effect of positioning for edentulous mandible by rotational panoramic radiography.<BR>Five dry mandibles were used in this study, and each mandible was tilted up to 30° using the mandibular positioner. Metal tubes were set vertically to the crest of the mandibular corpus of another mandible. The angle of mandibular plane and the angle of inclination of metal tubes were measured using rotational panoramic radiograms.<BR>There was a high correlation between the actual size and the measurement by rotational panoramic radiogram.<BR>It was possible that the mandibular corpus height was measured within 15° about the inclination of standard metal tubes. This study indicates that the angle measurements of mandibular plane and of the standard metal tubes on rotational panoramic radiogram were useful for accurate positioning.
