INTRODUCTION: Implant-supported metal-ceramic prostheses widely used for full arch and partial rehabilitation of missing teeth owing to their high mechanical stability, acceptable esthetics, cost effectiveness relative to all ceramic systems, and favorable long term clinical outcomes. However, porcelain chipping remains a common complication leading to patient discomfort, additional chair time, and increased costs. In such cases, rather than removing and refiring the entire restoration—which risks distortion, shrinkage, or cracking of the ceramic—it may be preferable to perform a localized repair limited to the chipped area. To propose a simplified alternative and minimally invasive approach for addressing porcelain chipping in metal-ceramic implant-supported prostheses. Case Description: A 44-year-old female patient presented with porcelain chipping in the maxillary right premolar region (teeth #13–14) several years after the completion of a metal-ceramic implant-supported prosthesis. The original prosthesis was a single-piece, full-arch maxillary restoration. Replacing the entire structure would require high-temperature furnace processing for porcelain layering, which carries substantial risks of material shrinkage and fracture. Instead, a conservative approach was adopted: the affected area was prepared like a tooth preparation, followed by conventional silicone impression-taking and digitization of the model to facilitate a digital workflow. The prosthetic design preserved the original tooth morphology, and a hybrid ceramic CAD/CAM block (GC Cerasmart) was selected as the restorative material. Dual-cure adhesive resin cement was used for bonding. Discussion: At 18 months of follow up, the repair exhibited excellent functional and esthetic stability, with only minimal surface staining noted and no further chipping or debonding.
