This study investigated objective and patient-reported esthetic outcomes and their correlation for single-tooth implant restorations in the maxillary anterior region.

Nineteen patients were included. Gingival biotypes and smile lines were evaluated. Esthetic evaluation was performed according to the pink and white esthetic scores (PES and WES). Patients rated their satisfaction regarding the implant treatment using a subjective outcome questionnaire and a 10-cm visual analogue scale (VAS).

The mean PES and WES were 10.7 (range 5–13, SD ± 2.24) and 8.6 (range 8–10, SD ± 0.60), respectively. The overall mean VAS was 8.54 ± 0.36 (range 3.8–9.8). No significant correlation was found between VAS and PES or WES (p = 0.475, p = 0.984, respectively). PES and WES scores for gingival biotypes failed to show any statistically significant difference (p = 0.701, p = 0.831). There was a significant negative correlation between the smile line and VAS; indicating that patients with lower smile lines expressed higher patient satisfaction (p = .001).

Professionally reported esthetic outcomes (PES and WES results) may not correlate with patient-reported outcomes. Smile line is a significant factor in patient satisfaction, which should be evaluated thoroughly prior to implant placement in the anterior maxilla.
