This case report records the replacement of two failed endodontically treated mandibular molars with one piece zirconia implants in a patient with metal hypersensitivity. The two molars were atraumatically extracted and curetted to remove any remnants of a periapical granuloma. Immediate implant placement with primary stability was achieved using one piece WhiteSky® Bredent zirconia implants which were restored after four months with a zirconia crown. One year follow up revealed successful osseointegration with optimal form and function.
