Abstract
Abstract Set-ups of sets of teeth individually selected from assortments of conventional and readily available false teeth are prepared on preformed dental arch ridge conforming blanks selected for the individual patient from a supply of sizes and configurations. Each blank has means for individually positioning each tooth of the set and serves as a support for the set-up enabling testing and adjusting in the mouth. Also, preselected sets of teeth may be supplied to dentists and technicians, each set of teeth being set-up in an appropriately sized blank. Thereafter the set-up including the blank serves as an integral part of the finished denture.
