From Root Canal to Royal Finish—A Direct Metal Laser Sintering Metal-ceramic Solution for Endodontically Treated Teeth: A Prosthodontic Perspective

Failures in endodontic treatment are often attributed to insufficient coronal sealing or poorly executed crown restorations, both of which can negatively impact the long-term prognosis of the tooth.Direct metal laser sintering (DMLS) metal-ceramic restorations have gained popularity due to their superior mechanical strength and reliability.This case involves a 45-year-old male patient who reported a noticeable swelling in the upper right posterior region.A previous restoration in the affected area was attempted but repeatedly dislodged, necessitating a more durable and long-lasting solution.Endodontic therapy was successfully completed in a single appointment, and a DMLS metal-ceramic crown was selected as the definitive restorative option.Direct metal laser sintering, an advanced additive manufacturing process, uses a high-powered laser to selectively fuse layers of metal powder, building the structure layer by layer in an inert gas environment to prevent oxidation.The application of DMLS-fabricated metal-ceramic crown on endodontically treated first premolar offers both functional and esthetic advantages, resulting in promising clinical outcomes.This case report aims to present the clinical protocol and outcomes associated with the use of DMLS-based porcelain-fused-to-metal (PFM) crown for first premolar restoration post-endodontic therapy.
