Impression Technique for Crafting Precise Cast Metal Posts in Permanent Anterior Teeth: A Report of Two Cases

Restoring endodontically treated young permanent anterior teeth with significant structural loss presents considerable restorative challenges, necessitating durable and well-fitting treatment options such as custom cast metal posts. Achieving precise post space impressions is critical for success; however, conventional methods have limitations. This case report presents two clinical cases involving three anterior teeth with large canals and introduces a direct technique for crafting custom cast metal posts, evaluated for its dimensional accuracy and clinical fit. Three young patients requiring post-and-core restorations following endodontic treatment of anterior teeth were managed using this technique. Subsequent fabrication and cementation of cast metal post-cores resulted in restorations demonstrating satisfactory volumetric accuracy, dimensional stability, and overall fit upon radiographic evaluation by independent examiners. No adverse postoperative signs or symptoms were observed during follow-up periods of three to six months. This technique proved to be a cost-effective, clinically efficient, and accurate method for obtaining post space impressions, particularly suitable for the large, tapered canals often found in young permanent anterior teeth. It offers a viable alternative to traditional materials, although further long-term clinical studies are warranted on different post space impression techniques.
