Objective: To analyze long-term facial soft tissues post-ERM with dental support (ERM-SD) and bone support (ERM-SO).Methods: 160 tomographic records from 3 groups were evaluated: ERM-SO, ERM-SD and CONTROL, at 3 times: T0 (pre-treatment), T1 (immediate post-treatment), T2 (2 years post-treatment); Parameters were measured: total convexity, facial convexity, nasolabial angle, mentolabial angle, facial height, nasal height, nasal length, upper lip height, upper vermilion height, lower lip height, lower vermilion height, chin projection, distance interocular, intercommissural distance, intercommissural width, alar base width and alar width. The results were analyzed with descriptive statistics, the percentage of change was evaluated, we compared the means obtained in pairs (t student) and an intergroup comparison (ANOVA and Tukey's post-hoc). Results: Long-term (T2-T0) statistically significant differences were found for the ERM-SO group in total convexity, facial height, upper lip height, lower lip height, intercommissural distance, width of the alar base, the ERM group -SD for total convexity, facial height, upper vermilion, lower lip height, lower vermilion, alar base width. No statistical differences were observed between ERM-SO, ERM-SD and CONTROL groups in the long term. Conclusion: ERM with bone or dental support generates a significant increase in the width of the nasal base that is maintained in the long term, but these facial effects are not different between the types of ERM and the control group.
