Tetra-Point Occlusal Technique in Fabrication of the Free-End Removable Partial Denture

Abstract

Maintaining vertical dimension is the most significant consideration as the restorations are fabricated. If the occlusals of the posteriors including premolars and molars are reduced at the same time, vertical dimension may be lost easily and it is realized by the operator that the further reduction may be required to obtain the necessary amount of occlusal space between the maxillary and mandibular posteriors. This undue loss of vertical dimension does not occur if some molars are left unprepared and occlude at the proper level of vertical dimension.
This article reported how to maintain occlusal position without altering vertical dimension throughout the whole procedures of fabrictation of the posterior restorations. The method is designated as“Tetra point occlusal technique.”and is effectively applied in fabricating the posterior prosthesies or free-end removable partial dentures.
