Research Abstract	To establish a simple and objective assessment of the residual ridge height and shape of edentulous patients, clinical utility of a newly developed "examination scale" based on our clinical research was investigated. The right and left first molars sections of 30 subjects with edentulous maxillae and mandibles were evaluated. Subjective evaluation and evaluation using an "examination scale" were carried out by 3 dentists. Results from our newly developed "examination scale" for residual ridge height and shape of edentulous patients correlated significantly with an objective evaluation, indicating high clinical utility of this scale.
