Clinical applications of concepts of functional anatomy and speech science to complete denture prosthodontics

Abstract In the first article of this series, the significance of the vitality factor of a patient was suggested, and the problems associated with attempts to “measure” functional anatomy were recognized. In the recording phases of denture construction, we are confronted with such problems. Necessarily, then, the development of impressions and the registrations of maxillomandibular relations involve a series of provisional steps which must be thoroughly tested and verified before acceptable final results are attained. Just as the preliminary modeling compound impression was the initial step in developing an accurate, functional, final impression, so the provisional maxillomandibular registrations, made with the occlusion rims, are the first approach to establishing the final registrations. With the selection of teeth and the placement of them in the occlusion rims, we continue our verifications of measurements of functional anatomy. This phase will be considered in the next article which will consider esthetic factors and carry the construction phases to their completion.
