Direct pattern techniques for cast post and core: A clinical comparison of resin and inlay wax in anterior tooth restoration

Restoration of endodontically treated anterior teeth with significant coronal loss presents both functional and aesthetic challenges. Custom cast post and core restorations remain a reliable option, especially when there is minimal remaining tooth structure. This case report presents two clinical approaches to custom post fabrication using direct techniques: pattern resin and inlay wax. In Case 1, a 22-year-old male with a fractured maxillary central incisor (tooth #11) following trauma was managed using a resin-based direct impression technique. In Case 2, a 30-year-old male with discoloration and structural compromise of tooth #21 was treated using an inlay wax pattern. Both cases involved post space preparation, preservation of a 4 mm apical seal, and fabrication of a custom metal post and core, followed by full-coverage restorations. Pattern resin offered superior handling, dimensional stability, and ease of removal without distortion. In contrast, inlay wax was more technique-sensitive and prone to deformation. While both techniques resulted in clinically acceptable outcomes, these findings reinforce the importance of material selection based on clinical needs and operator proficiency.
