Objective: To investigate whether there is a relationship between the distance between the iris and pupil with the ideal size of buccal corridors. Materials and Methods: A full‐portrait image of a male Caucasian was used to create a set of 11 digitally modified images with different buccal corridor space. A web‐based cross‐sectional study was designed and distributed via an online survey to 200 laypeople and 200 orthodontists to assess image attractiveness, using a Visual analogue scale. For the statistical analysis, Wilcoxon signed‐rank and Mann–Whitney U tests were used. The significance level was set at p < 0.05. Results: The response rate for laypeople was 70% (n = 139), while the rate for orthodontists was 73% (n = 146). For the layperson group, the maximum smile attractiveness score was 10% of buccal width reduction, compared to the iris‐pupillary distance, while for the orthodontists, it was 20%. The attractiveness of the smile was significantly reduced in both groups when the buccal corridor width was increased in comparison to the iris‐pupillary distance. Conclusion: The length between the mesial part of the iris and the distal of the pupil, may constitutes a landmark for the estimation of the desired width of the buccal corridor. Clinical Relevance: Inter iris‐pupillary distance can be the starting point in the smile designing process, in order to perform a facial driven selection of buccal corridor size.

A patient's vertical dimension measurement is an important factor for the clinician to consider when planning an oral rehabilitation. Establishing the correct occlusal vertical dimension (OVD) is dependent upon dental and facial analysis, the latter of which should include measurements of facial anatomic points and evaluation of facial ratios. However, dentists may find it challenging to transfer planned measurements to the patient's mouth. This article describes an interocclusal device, called the esthetic jig, which is created according to customized parameters for each patient and that can help dentists to properly achieve the correct OVD.
