title: An esthetic comparison of a metal ceramic crown and cast metal abutment with an all-ceramic crown and zirconia abutment: a clinical report.
abstract: This clinical report compares the esthetic outcome of replacing the same left maxillary central incisor with 2 types of implant-supported restorations, a zirconia abutment with a Procera crown and a custom metal abutment with metal ceramic crown. There were only subtle differences noted and both restorations yielded a satisfactory result.
