VACUUM-FORMED MATRIX AS A GUIDE FOR THE FABRICATION OF MULTIPLE DIRECT PATTERNS FOR CAST POSTS AND CORES

Fabrication of multiple posts and cores for severely damaged pulpless teeth is arduous because few landmarks remain. Esthetic requirements, occlusal relations, and long axes of the planned final restorations in fluence the core design. This article describes a method for directly verifying fabricated post-and-core patterns by combining the procedure s for malting a thermoformed shell for a preparation template and crea ting a plastic template for multiple core pattern fabrication.
