Clinical Study for the Determination of the Golden Ratio among the Heights of Facial Areas in Removable Prostheses and the Appropriate Occlusal Height by X-ray Cephalic Analysis

Abstract

The golden ratio among the heights of facial areas is used as aesthetic criteria in orthodontic diagnosis. However, in the aesthetics of the living body, functional beauty with functional elements is originally important.
We attempted to establish a scientific method of clinically determining the appropriate occlusal height by Ricketts' cephalic analysis for removable prostheses and the golden ratio among heights of facial areas.
The mean golden ratio among heights of facial areas in 25 edentulous subjects was 1.61296 and the standard deviation was 0.1005.
This value was similar to the mean golden ratio (1.612) calculated by Yazawa and Takayama based on Ricketts' heights of each area of the face.
