Abstract

When wearing complete dentures, patients want to function naturally within a physiologically stable range. To do this, recovery of esthetics, biologically stable arrangement and contour, and occlusal contacts with denture stability are necessary. In this case report, a complete denture patient of adverse conditions was presented. To increase stability of the dentures, functional impression was made by border molding using the neutral zone. The dentures were checked for physiological centric relations and stable occlusion. The clinical results showed satisfactory results on function and esthetics.
