A patient who experienced root fracture of a maxillary left central incisor received a titanium implant on the same day as extraction. After delayed implant loading, a two-piece zirconia abutment with metallic insertion was customized. Upon installation, a horizontal fracture of the crown just above the metallic portion was detected. The retrieval analysis of a fractured zirconia abutment showed crack formation and diffusion of glaze material that expanded the crack line during firing.164-168engDental ImplantsZirconiaProsthesis Failure AnalysesPeriprosthetic FracturesDental Implant-Abutment DesignDental PorcelainArtigo10.1922/EJPRD_01556Bottino05WOS:000411710300007Acesso restrito9234456003563666
