Abstract

A technique is described for the fabrication of a full arch maxillary passive-fitting, screw-retained, rigid ceramometal prosthesis. The two posterior segments containing Screw-Bloc attachments are cast initially. The waxed anterior segment with its attachments is then aligned to the cast posterior segments and cast. Porcelain is fired to the individual segments in an attempt to reduce deformation, which occurs when large ceramometal restorations are constructed. When the prosthesis is completely fabricated, the segments are assembled on the master cast and the attachments on the posterior segments are tapped to receive the screws, which rigidly attach them to the anterior segment. The Screw-Bloc attachment has an irregular configuration that resists rotation of the individual segments. The segments are united once the passively aligned screws are tightened. A clinical report is presented.
