A cephalometric approach to establish the vertical facial dimension: An in vitro study

Evaluating the maxilla-mandibular vertical dimension is of great importance in constructing successful denture prosthesis, however it is a tedious process which may be misinterpreted leading to false readings. Hence with the aid of cephalometric analysis a cephalogram may present a graphic representation .this study aims to introduce a new mathematical method for of determination the occlusal vertical dimension (O.V.D.). : The first part was conducted to derive a clinical ratio between the O.V.D. and the ear-eye distance, as well as to derive a radiographical ratio between the same distances on a lateral cephalometric view. The second part of this study aimed to evaluate the accuracy of clinical and radiographical application of the ratios that were derived from the first part in estimating the O.V.D from the ear-eye distance measured in dentate subjects.
