Anterior maxillary area is called “esthetic zone”. Sometimes in implant restoration, metal abutments can make tissue discoloration on the cervical area. Zirconia abutment is an alternative for the use in esthetic zone because it doesn't cause tissue discoloration. This article describes four cases where zirconia abutments were used in anterior maxillary area with allceramic restorations. Though one case suffered the fracture of all-ceramic restoration, three of the four cases had good esthetic and functional results.
