Improving darkened anterior peri-implant tissue color with zirconia custom implant abutments.
Tissue discoloration in the cervical third of anterior implant restorations may result from implant abutment material show-through. As an alternative to metal abutments that may compromise the appearance of tissue color in the esthetic zone, zirconia abutments can be used. When zirconia abutments are combined with all-ceramic crowns, the appearance of the peri-implant tissue can be noticeably improved. This article describes two cases where a zirconia abutment replaced an existing metal abutment in a single anterior implant restoration.
