Factors affecting smile esthetics in adults with different types of anterior overjet malocclusion.

- Korean J Orthod 2017;47:31-38

I appreciate the authors for this interesting article about smile.

I think that the smile line is very important esthetic point to finish orthodontic treatment. I have some questions that are listed below.

Q1. Although this question may not be concerned with your article theme, which factor in your smile measurements do you think is the most crucial in each skeletal group for making a good smile, considering the fact that you have a profound knowledge of smile analysis?

Q2. The buccal corridor is one of the important factors for making a beautiful smile. I have anticipated that the buccal corridor ratio in J2 group would be higher than the other groups because Class II vertical patients were often associated with a smaller molar width than the normal group. But the result did not go as I expected. What do you think about this result?

Tables


Comparison of smile measurements between different types of anterior overjet malocclusion using ANOVA



Values are presented as mean ± standard error.

Group J1, 0 < OJ < 4 mm; Group J2, OJ > 4 mm; Group J3, OJ < 0 mm.

*p < 0.05, p < 0.01, p < 0.001; the post hoc test: J1 vs. J2, J1 vs. J3, J2 vs. J3.
