Preparation of complete denture with neutral zone stability: Case report

The aims of making complete dentures are to repair the functional losses of a patient, provide proper phonation and to improve aesthetics. Ensuring both denture retention and its stability is of paramount importance. Retention depends on the accuracy of the impressions from the patient and the congruence of the denture base with the tissue, and stability relies on tooth position, base flange form, contour of the polished surfaces, and the amount of occlusion. It has been reported in the literature that, muscle functions of the cheek, lips and tongue are major factors for the dentures stability. The stability factors besides occlusion are known to be determined by the procedures in defining the neutral zone. Thus definition of neutral zone is necessary to provide stability in dentures. In our two cases, we present the preparation of complete denture for an edentulous patient.
