Abstract
Prosthetic rehabilitation of edentulous patients can sometimes pose many clinical challenges for the clinician. The importance of correct vertical and horizontal positioning of the anterior teeth so that the completed denture is esthetically pleasing while being functionally correct has been well documented in the literature. Different techniques have been proposed whereby a conventional occlusal rim is used. The wax-rim thickness of this design can interfere with the neutral zone, making normal phonetics difficult. In this report, a completely edentulous patient received treatment using a modified occlusal rim so that phonetics could be used to determine the anterior tooth position and vertical dimension, following a strict adherence to a clinical protocol. The methodology involved the use of heat-processed resin record bases and a thin segment of baseplate wax that mimics anterior teeth. This approach resulted in a more natural feeling for the patient and provided the clinician the necessary information for the laboratory, which was easily communicated.
