    Custom porcelain-fused-to-metal pontics offer superior esthetics for removable partial dentures. These dental prosthetics can be easily customized to match natural teeth when replacing isolated anterior teeth.

    Area of Science:

    • Dental prosthetics
    • Materials science in dentistry
    • Removable partial dentures

    Background:

    • Replacing missing teeth, especially isolated maxillary anterior teeth, presents esthetic challenges in removable partial denture (RPD) fabrication.
    • Traditional pontic materials may not always meet the esthetic demands for anterior tooth replacement.

    Purpose of the Study:

    • To evaluate the esthetic potential of custom-made porcelain-fused-to-metal (PFM) ring pontics for RPDs.
    • To describe the fabrication and characterization procedures for PFM ring pontics.

    Main Methods:

    • Custom PFM ring pontics were fabricated for RPD applications.
    • Standard porcelain characterization and glazing techniques were employed.
    • The pontics were designed to replace isolated maxillary anterior teeth.

    Main Results:

    • The custom PFM ring pontics can be effectively color characterized and glazed using conventional dental laboratory procedures.
    • The use of PFM ring pontics demonstrated potential for achieving superior esthetic outcomes compared to other pontic types in RPDs.

    Conclusions:

    • Custom PFM ring pontics are a viable option for enhancing the esthetics of RPDs, particularly for replacing single missing anterior teeth.
    • Familiar laboratory procedures allow for effective customization and glazing of these advanced dental prosthetics.
