• Resumen

  • This clinical report describes a mandibular full-arch rehabilitation by means of an implant-supported overdenture on four zirconia implants. A female patient with an edentulous mandibular arch attended our dental clinic seeking a metal-free mandibular restoration. After oral and radiographic evaluation, four one-piece zirconia implants with conical abutments were placed in the intermentonian region. After a 3-month osseointegration period, an acrylic overdenture with plastic matrices was manufactured, supported by a zirconia bar cemented to the conical abutments of the zirconia implants. Radiographic and clinical follow-up after 12 years observed adequate implant evolution, without any signs of peri-implant disease. Maintenance events were principally the periodic replacement of the plastic matrices and prophylaxis.
