Impact of functional orthodontic treatment on facial attractiveness of children with Class II division 1 malocclusion

Abstract

Summary Background/objectives Whether orthodontic treatment with functional appliances improves facial aesthetics is still under debate. This study aimed to determine whether functional orthodontic treatment improves the facial attractiveness of patients with Class II division 1 malocclusion. Materials/method Extraoral lateral photographs of 20 children with Class I (CLI, 11.7 ± 0.8 years), and before (T1) and after treatment (T2) photographs of patients with Class II division 1 (CLII T1 and CLII T2; mean age ± SD = 11.1 ± 0.6 years) treated with functional appliances, were transformed into black silhouettes. Three panels of examiners including 30 orthodontists (39.0 ± 10.1 years), 30 dentists (40.0 ± 9.7) and 30 laypersons (39.0 ± 9.2) evaluated the attractiveness of patients’ silhouettes using a 100-mm visual analogue scale, and the sagittal position of patients’ upper lip, lower lip, and chin using a 3-point Likert scale. Two-way ANOVA and a chi-square test were used to test differences among groups. Statistically significance was set as P < 0.05. Results The silhouettes of CLII T2 individuals were more attractive than those of the other groups (all Ps < 0.001). The upper lip, lower lip, and the chin of these individuals were judged to be normally positioned in 69.5 per cent, 74.9 per cent, and 72.3 per cent of the assessments, respectively (all Ps < 0.05). Limitations This study did not account for the psychological profile of the examiners, which may have affected the ratings. Conclusions/implications Orthodontic treatment with functional appliances is associated with a superior facial profile attractiveness. Functional treatment should be considered as a treatment option to improve the facial appearance of children with Class II division 1 malocclusion.

Evaluation of Profile Changes in Class II Individuals Treated by Means of Herbst Miniscope Appliance

“…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.…”

“…Although aesthetic improvement is the patient's primary goal, few studies have investigated the perception of profile and soft tissue improvements resulting from functional therapy [19,20]. Only one retrospective study investigated the effects of the Herbst appliance on the soft tissue profile by comparing it with an activator [21].…”

“…Um dos objetivos do tratamento da má oclusão de Classe II é a diminuição da convexidade facial, para essa fi nalidade são usados aparelhos funcionais (removíveis ou fi xos) ou a cirurgia ortognática para dar ao paciente um perfi l facial mais retilíneo com o avanço mandibular (VON BREMEN et al, 2014). A análise de alguns fatores como a idade do paciente, o tamanho da discrepância e a percepção do perfi l facial pelo paciente e seus pares são fundamentais para se chegar a um correto plano de tratamento (PADUANO et al, 2020).…”

Consideraciones clínicas en un paciente con hipertonicidad muscular de mentón. Reporte de caso

“…[3][4] La hipertonicidad del mentón sugiere una incompetencia labial, ya que repercute en la estética facial, tomando en cuenta que actualmente ha aumentado su demanda en el número de pacientes, siendo este un factor re-levante para completar un tratamiento ortognático y de ortodoncia. [5][6] Hay más de veinte músculos en el rostro humano. Particularmente en el área de los labios y las mejillas; muchos músculos convergen o se entremezclan.…”

“…[3][4] Chin hypertonicity suggests a labial incompetence, since it affects facial aesthetics, taking into account that currently it has increased its demand in the number of patients, this being a re-lifting factor to complete an orthognathic and orthodontic treatment. [5][6] There are more than twenty muscles in the human face. Particularly in the area of the lips and cheeks; Many muscles converge or intermingle.…”
