Abstract
In our study using rotational panoramic radiography for quantitative analysis of edentulous patients, a new mandibular positioner was developed and reformed to measure mandibular corpus height in dried human mandibles.
The purpose of this study was to examine the mandibular bone height in edentulous patients.
Six edentulous patients were chosen, and each subject was set on the mandibular positioner for rotational panoramic radiography. The mandibular plane of the patient was positioned horizontally with the mandibular positioner and eight metal tubes were vertically placed into the occlusal rim at the crest of the mandibular corpus.
The mandibular corpus height of six patients were estimated by calculating the magnification rate of metal tubes obtained from the rotational panoramic radiogram.
In this study, it was found that calculation of edentulous mandibular corpus height was clinically possible by using the metal tubes and the mandibular positioner.
