Outcome Evaluation of Early Placed Maxillary Anterior Single‐Tooth Implants Using Objective Esthetic Criteria: A Cross‐Sectional, Retrospective Study in 45 Patients With a 2‐ to 4‐Year Follow‐Up Using Pink and White Esthetic Scores

This study demonstrated that anterior maxillary single-tooth replacement, according to the concept of early implant placement, is a successful and predictable treatment modality, in general, and from an esthetic point of view, in particular. The suitability of the PES/WES index for the objective outcome assessment of the esthetic dimension of anterior single-tooth implants was confirmed. However, prospective clinical trials are needed to further validate and refine this index.
