Trigonometric method of analysis of the upper part of the mouth cavity.
A method of analysis of a cast of the upper part of the mouth cavity which allows a comparison of various forms thereof, by the use of five parameters is described. For their calculation, only five measurements between four pre-determined points are needed. With the great accuracy which the method ensures, it is possible to follow, at short time intervals, the changes brought about by jaw-orthopaedic and surgical procedures. Numerical and schematic graphical comparison permits a rapid evaluation of results achieved in the treatment of clefts. The character of the parameters elucidates the morphogenesis of clefts and indicates the most rational therapy.
