An effective pattern of occlusion in complete artificial dentures

Abstract

An effective pattern of occlusion entails the need for varying occlusal alterations to insure conformity with individual functional requirements. Mounted diamond stones, where feasible, can he used to advantage to facilitate and expedite the technique. Successful, gratifying solution of the full denture problem demands a maximum effort. A minimum effort invariably yields a minimum result. A scheme of occlusion carefully integrating the gnathodynamic factors of occlusion and based upon sound physiologic principles has been outlined. The use of thirty-three degree posterior anatomic teeth providing maximum cusp and surface contact throughout the entire range of functional jaw movements will afford maximum masticatory efficiency. Stability is enhanced by the proper positioning of the mandibular posteriors buccolingually so that a perpendicular dropped through the buccal cusps will bisect the crest of the ridge. The lingual position must not extend beyond the internal oblique line to avoid encroachment upon the tongue space. Further protection is afforded the underlying bone and tissue supports through a reduction in the inclination of the guiding inclines. Shallow but sharp cusp teeth functioning against smooth, harmonious inclines and developed through a definite procedure of selective grinding will furnish maximum masticatory efficiency without jeopardizing either retention or stability. Correct centering of the entire occlusal load anteroposteriorly is essential. Suitably selected anatomic teeth modified in the manner indicated will provide an adequate masticatory table, permit free mandibular movements and be highly esthetic in appearance.
