The purpose of this research was to define the smile height in relation to facial biotype in students aged 15-17 at Huaycán Mixed School N° 1236, Peru, 2015. Facial height and width were measured clinically using a digital Vernier caliper, and photographs of spontaneous smiles were taken and evaluated. The study was observational, prospective, cross-sectional, descriptive, and relational. The sample consisted of 244 students who met the inclusion criteria. Data analysis was performed using the chi-square correlation test for related samples, with a 95% confidence level and a 5% margin of error. The results showed a significant difference in smile height in relation to facial biotype in both genders. Leptoprosopic (dolichofacial) students had high smile height, mesoprosopic (mesofacial) students had medium smile height, and euriprosopic (brachyfacial) students had low smile height. The difference was not significant for age. In conclusion, the results demonstrated that smile height should be applied according to facial biotype, as statistically significant differences were found.
