Background : Esthetic evaluation of implant-supported single crowns: a comparison of objective and patient-reported outcomes [2]

Patient satisfaction, which indicates the success of the implant treatment from the patient’s perspective, is another important outcome measure and is commonly performed with questionnaires or a visual analog scale (VAS) [2, 8]. A current review of the literature, however, reveals only a limited number of studies reporting on patient-centered outcomes in addition to objective evaluations of implant-supported rehabilitations in the anterior maxilla. Among these, few studies previously reported that objective assessments may fail to reflect subjective patient outcomes [11,12,13]. Therefore, this study aims to investigate and report objective and patient-reported esthetic outcomes and how well they correlate for single-tooth implant restorations in the maxillary anterior region.
