Cad-Cam Fabricated One-Piece Ceramic Post and Core for Teeth Supporting Fixed Partial Dentures: Report of Two Cases

Endodontically treated teeth with inadequate tooth support can be rehabilitated either prefabricated or custom fabricated post and core materials. Custom post-core restorations are fabricated by casting or computer aided design and computer aided manufacturing (CAD-CAM) systems. It is recommended that teeth treated with post and core restorations should be one-piece and adequate fit of the post into the root canal should be achieved for supporting fixed partial dentures. The purpose of this clinical report is to represent chairside treatment procedures of two patients who received all ceramic fixed partial dentures with one-piece CAD-CAM generated ceramic post core restored abutment teeth. In the first case, it is presented that maxillary central teeth restored with one-piece ceramic post and core for supporting fixed partial denture on the anterior region. In the second case, it is presented that mandibular premolar tooth restored with one-piece zirconia post and core for supporting fixed partial denture on the posterior region. Both cases were treated with CAD-CAM fabricated fixed partial dentures after the cementation of posts and cores. During one-year follow-up period, the patients were satisfied with their prostheses esthetically and functionally. No complication was observed during the follow up period.
