“…Thus, when assessing the orthodontic treatment outcome, which aims to improve facial esthetics, studies need to focus on the opinion of different groups of evaluators, including also the subjective layperson’s opinion, which comprise the target group of our treatments. Previously, only a small favorable change in facial appearance was perceived when raters were asked to evaluate the esthetic outcome of functional orthodontic treatment on convex profile class II division 1 patients [9]. This underlines the need for more studies investigating the perceived improvement of facial appearance, achieved by treatments that have such aims.…”

“…Current literature focuses on the improvement of patients’ facial profile following skeletal and dentoalveolar class II correction [2, 3, 5, 10–16]. Indeed, functional appliances may influence to some degree the patients’ facial profile [5, 10, 11, 13, 15] and this might be perceivable by the human eye as more attractive [9, 13, 14]. However, facial attractiveness is evaluated in everyday life from different angles and not only from the profile view and this may impact esthetic assessments [17].…”

“…So far, there is only one study that investigated the esthetic improvement of convex profile patients, after treatment with functional followed by fixed orthodontic appliances, using actual images [9]. In that study, raters assessed actual facial profile photographs before and after the orthodontic intervention and perceived a slight improvement in the esthetic appearance.…”

Objectives: To assess the perceived facial changes in class II division 1, convex profile patients treated with functional followed by fixed orthodontic appliances. Subjects and methods: The study sample consisted of 36 pairs of pre-and post-treatment photographs (frontal and profile, at rest) of 12 patients treated with activator, 12 with twin-block, and 12 controls with normal profiles, treated without functional appliances. All photographs were presented in pairs to 10 orthodontists, 10 patients, 10 parents, and 10 laypersons. Visual analog scale (VAS) ratings of changes in facial appearance were assessed. Results: The patient groups were similar in sex distributions, age, and treatment duration. The different rater groups showed strong to excellent agreement. There were no significant differences among treatment groups (F = 0.91; P = 0.526; Wilks lambda = 0.93), raters (F = 1.68; P = 0.054; Wilks lambda = 0.83), and when testing the combined effect of treatment and rater on the results (F = 0.72; P = 0.866; Wilks lambda = 0.85). The raters detected slightly more positive changes in the activator and twin-block groups, compared to the control group, regarding the lower face and the lips, but these findings did not reach significance. Furthermore, their magnitude hardly exceeded 1/20th of the total VAS length. Limitations: Retrospective study design. Conclusions: The perceived facial changes of convex profile patients treated with functional, followed by fixed orthodontic appliances, did not differ from those observed in normal profile patients, when full-face frontal and profile photos were simultaneously assessed. Consequently, professionals should be skeptical regarding the improvement of a patient's facial appearance when this treatment option is used.

“…The results are also in accordance with two studies [20,37] that investigated the perception of facial attractiveness assessed by orthodontists, general pratictioners and laypersons after Herbst appliance treatment. Another study [38] reported no significant improvement in perceived facial changes after Class II treatment with functional appliances and fixed therapy, but the patients were not treated with the Herbst appliance.…”

Background: To evaluate the profile changes following orthopedic/orthodontic treatment with the Herbst Miniscope® appliance in subjects affected with Class II malocclusion with mandibular retrusion. Methods: A total of 44 patients presenting a skeletal Angle Class II malocclusion (ANB > 4°) due to mandibular retrusion and a cervical maturation stage between CS2 and CS3 were included in the study. Of these 44 patients, 22 (mean age 11.9 ± 1.3, HBT group) were treated using the Herbst appliance, while 22 (mean age 10.6 ± 1.3, CTR group) were followed for a 12-month observational period. A cephalometric tracing was performed at the beginning of treatment (T0) and after 12 months (T1). Results: In both groups there was a significant advancement of soft tissue pogonion (HBT = 3.5 ± 3.0 mm, p < 0.001; CTR = 2.2 ± 2.9 mm, p < 0.001), but the difference between the two groups was not significant (p = 0.172). On the contrary, both groups had a significant advancement of the mandibular sulcus (HBT = 3.7 ± 2.8 mm, p < 0.001; CTR = 1.2 ± 2.2 mm, p < 0.001) and a lower lip protrusion (HBT = 3.45 ± 2.51 mm, p < 0.001; CTR = 1.7 ± 2.7 mm, p = 0.008), but in both cases the HBT group showed a statistically significant greater increase in sulcus protrusion (p = 0.002) and lower lip protrusion (p = 0.029) than controls. There were no statistically significant effects on the upper jaw. Conclusions: The Herbst appliance advanced the lower jaw soft tissues.

“…This finding may be related to the restrictive effect that functional appliances exert on the maxillary component. 20,[44][45][46] Another alteration observed was that the mandibular lips presented a mild protrusion in the treated groups while the control presented retrusion. This finding is probably related (even without being significant) to the skeletal effects promoted by the appliances.…”
