Fabricating a custom zirconia post-and-core without a post-and-core pattern or a scan post

Abstract

Due to the increased esthetic demands, custom zirconia post-and-cores have recently become popular. A post-and-core pattern with acrylic resin or wax is scanned using a laboratory scanner for the design of a definitive post-and-core restoration. This procedure requires additional time and material handling experience. If a scan post is used for an intracanal digital scan, substantial initial investments for hardware and software are required. This article introduces an alternative technique for fabricating a custom zirconia post-and-core with a conventional impression. By using this technique, a properly fitted zirconia post-and-core is quickly and easily fabricated with less human error.
