Golden proportions between facial vertical dimensions described by Ricketts4, 5) and equations used by various methods for determining an optimum occlusal vertical dimension were analysed algebraically. Among total eleven relations ( (1) - (11) ), nine relations ( (3) - (11) ) were proved to be derived algebraically from the residual two most simple and fundamental relations ( (1) & (2) ) .
The methods used for determining an optimum occlusal vertical dimension are reasonable for complete denture use in view of golden proportion and influence of pathologic occlusal vertical dimension.
To establish the general method for determining an optimum occlusal vertical demension in view of golden proportion scientifically, epidemiological study is needed. The necessary steps for the study were recommended.
