A pilot study enrolled prosthodontists and periodontists to review and verify the representations. A 29-question survey was developed and distributed to 33 participants on a tablet computer to evaluate the photographs. The participants were asked about their satisfaction level with the photographs on a visual analog scale from 0 to 100. Data were extracted, and ANOVA was used to compare mean satisfaction scores.

Based on the patient survey, 5 of the 14 factors of the PES/WES showed no significant difference and were eliminated when constructing the index. Using scores and percentages, the anterior implant esthetic index was developed for scores of 0, 1, and 2 for each of the remaining 9 criteria.
