The upper anterior sectional denture.
An upper anterior sectional denture is described which consists of (1) a cast cobalt-chromium framework with two passive clasps that contact undercuts on the distal surfaces of the most posterior remaining teeth and (2) a labial flange that carries the replaced tooth or teeth and engages the labiointerproximal gingival undercuts of the anterior teeth adjacent to the edentulous ridge. The cast framework is inserted occlusogingivally, and the labial flange is inserted labiolingually. Both sections are held together by the frictional resistance of the split post of the framework that fits into a tube on the labial flange and hollowed-out artificial tooth. With this type of prosthesis, certain clinical problems can be handled without abutment tooth preparation and with a minimal amount of chair time.
