A precise design and fabrication method for metal base maxillary complete dentures

Metal bases sometimes are used to enhance the physical properties of complete dentures. Unfortunately, improper positioning of metal-resin finish lines may adversely affect phonetics. In the past, placement of these finish lines has been somewhat arbitrary. This article describes a precise method for the placement and contour of metal-resin finish lines. The resultant prostheses should exhibit surfaces that reestablish proper anatomic, physiologic, and phonetic contours.
