Abstract
In the treatment of edentulous patients, determination of vertical occlusal height, inclination of the occlusal plane and proper anterior guidance have been fundamental and difficult subjects for fabricating a individual total prosthesis. In this communication, we describe the novel approach to fabricate the total prosthesis based on the information obtained from analysis of roentogenocephalogram and record of functional condylar path collected by computerized axiography. Values of lower facial height (LFH) and the ratios of upper facial height (N-ANS) and lower facial height (ANS-Gn) to the total facial height (N-Gn) were measured and evaluated in order to determine the vertical dimension of new prosthesis. Furthermore, functional condylar paths with mandibular open-close, protrusion-retrusion, and mediotrusion-medioretrusion movements were utilized to evaluate the neuromuscular function of masticatory system. Sequential functional guidance occlusion scheme described by Slavicek was incorporated onto new prosthesis. These approach were able to provide the harmonious relation of anterior and posterior guidance in orofacial muscular function.
