“… 14 , 15 , 26 Among the measurements of lip position, the distances from the upper and lower lips to the E line, Z angle, and H angle have been regarded as suitable assessments in different study samples. 21 , 22 , 26 – 28 In addition, chin prominence and variables related to the contour of the mentolabial fold are sensitive parameters in the facial evaluation. 21 , 22 Consistent with previous studies, our results demonstrated that the distances from the upper and lower lips to the E line, the H angle, the distance from the lower lip to the H line (all of which represent the lip position), and the PMA (which represents the chin morphology) had a negative influence on the entire facial attractiveness.…”

“… 18 – 20 Some researchers have explored the relationship between cephalometric measurements of the lip position and facial esthetics; however, the results are far from conclusive. 21 – 24 Additionally, few studies have investigated the contributions of different facial parts to the entire facial esthetics. The potential correlation between objective measurements and subjective evaluations of different facial parts requires further examination.…”

Objective To investigate the correlations between objective measurements and subjective evaluations of post-treatment facial attractiveness. Methods Ten orthodontists rated the subjective visual analog scale (VAS) scores of the facial profiles of 95 patients who had undergone orthodontic treatment. Post-treatment cephalograms and photographs were used. Eleven soft tissue measurements and eight maxillary incisor measurements were constructed and analyzed. Correlations between objective measurements and subjective VAS scores were evaluated using Pearson correlation and quadratic regression analysis. Results The VAS scores of different facial proportions were all correlated with the total VAS score. Among soft tissue measurements, the distances from the upper and lower lips to the E line, H angle, forehead inclination, distance from lower lip to the H line, and pogonion-menton angle were negatively correlated with the VAS scores. The Z angle, with a parabolic distribution, was also correlated with the VAS scores. Among maxillary incisor measurements, the distance from the maxillary incisors to the forehead’s anterior limit line and the angulation of the maxillary incisors to the APo line were negatively correlated with the VAS scores. Conclusions Several soft tissue and maxillary incisor position measurements were correlated with facial profile evaluation and therefore might be used to evaluate facial attractiveness.

“…But the teeth especially the anterior teeth are forwardly placed leading to an appearance of prominence of soft tissues (lip). 1,2 In this case the molar canine and incisor relation are class I. Furthermore, in bimaxillary prognathism, the jaw bones (basal) remain forward in relation to to the cranial bone.…”

This article has no abstract. The first 100 words appear below: A 14-year-old male came to the outpatient Department with the complaints of proclination of the tooth and inability to close his lips. The patient was psychologically depressed for his facial appearance. Extraoral clinical examination showed a mesocephalic symmetrical face with convex facial profile as well as his lower lip was trapped The nasolabial angle was acute. His mandibular movement was normal and there was no temporomandibular joint dysfunction.

The treatment of Class II can have a positive or a negative impact on the facial profile aesthetic. The present study aims to evaluate the impact of two methods of orthodontic treatment of Class II malocclusion on the facial profile aesthetics. The facial profiles of 46 patients with Class II malocclusion were outlined by radiography before and after treatment; 23 of the patients were treated by the extraction of two maxillary first premolars (EXT group), and the other 23, with the Thurow Appliance (TA group), followed by braces. The profile silhouettes were filled in using the Corel Draw program. An album containing the patient’s silhouettes of both groups was created randomly, with two profiles of a patient per page. The preferences of 30 orthodontists, 30 dentists, and 30 laypersons in relation to the profile were recorded along with their perceived differences between the pre-treatment and post-treatment profiles, according to the visual analog scale. All groups of evaluators preferred the post-treatment profile more frequently. There were statistically significant differences in the evaluators’ preferences only between the orthodontists’ and the laypersons’ groups. None of the evaluators’ groups indicated substantial differences between the pre-treatment and post-treatment profiles. It may be concluded that both Class II treatment protocols, i.e., the double-extraction of the first premolars and the use of TA, improved the patients’ facial profile aesthetics.Keywords: Face.

O objetivo deste estudo foi avaliar o impacto da estética do perfil facial decorrente de dois tipos de tratamento para a Classe II. Foram traçados os perfis faciais das telerradiografias pré e pós-tratamento de 46 pacientes Classe II, sendo 23 de um grupo tratado com extração de dois primeiros pré-molares superiores e 23 de um grupo tratado com AEB Conjugado seguido de aparelho fixo, e estes traçados foram preenchidos com o programa Corel Draw. Foi montado um álbum com as silhuetas dos pacientes (AEB e EXO) de forma aleatória, sendo dois perfis em cada folha do mesmo paciente. Foi pedido para 30 ortodontistas, 30 cirurgiões-dentistas e 30 leigos para verificarem a sua preferência em relação ao perfil e a quantidade de diferença entre os perfis pré e pós-tratamento, de acordo com a escala analógica visual. Os 3 grupos de avaliadores preferiram o perfil pós-tratamento com maior frequência. Houve diferenças estatisticamente significantes somente entre os grupos de avaliadores ortodontistas e leigos; os 3 grupos de avaliadores indicaram que os perfis pré e pós-tratamento, não diferiram substancialmente. Pode-se concluir que o tratamento da Classe II, com extração de dois primeiros pré-molares, e com o uso do aparelho AEB Conjugado produziu um impacto positivo na estética do perfil.Palavras-chave: Face.
