ABSTRACT

Aim: To assess the perception of facial attractiveness in profile digital images in the sagital and vertical plan. Methods: The facial profiles of 80 patients (20 Class II, 20 Class III, 20 open bite and 20 deep bite) male and female samples were evaluated. The lateral cephalometry radiographs of the all samples were digitized and systematically altered regarding the location of the mandible and maxilla in the sagital and vertical plan, using Dolphin Imaging software program (version 10.0). Five manipulated profile images together with the patients' own profile were presented to the raters including laypersons, orthodontists and surgeons. The facial attractiveness of the profile images were assessed using a 6-scaled (visual analogue scale). The data were analyzed using Kruskal Wallis and Mann Whitney U tests. Results: The most attractive facial profiles were normal images in both patients' groups as assessed by all judges Severe Class III facial profiles in both Class II and Class III patients' images and severe open bite facial profiles in both deep bite and open bite patients' images ranked as the least attractive. No significant differences were found in the overall rankings of male and female profile images between female and male raters. Conclusion: The profile attractiveness decreased with the more deviations from the normal profile proportions and more scattered ideas were shown by raters. Specialists can use the results of the beauty perception by the laypersons to modify the treatments and consequently increase the patients' satisfaction.


Objetivo: Avaliar a percepção da atratividade facial em imagens digitais de perfil no plano sagital e vertical. Método: Foram avaliados perfis faciais de 80 pacientes (20 Classe II, 20 Classe III, 20 mordida aberta e 20 mordida profunda), pertencentes ao sexo masculino e ao feminino. As radiografias cefalométricas de todos os indivíduos foram digitalizadas e sistematicamente alteradas em relação à localização da mandíbula e da maxila no plano sagital e vertical, usando o software Dolphin Imaging (versão 10.0). Cinco imagens de perfil, manipuladas em conjunto com o perfil dos próprios pacientes, foram apresentadas aos avaliadores, incluindo leigos, ortodontistas e cirurgiões. A atratividade facial das imagens de perfil foram avaliadas através de uma escala visual analógica. Os dados foram analisados pelo teste de Kruskal Wallis e Mann Whitney. Resultados: Os perfis faciais mais atrativos foram os de imagens normais, em ambos os grupos de pacientes, sendo considerado por todos os avaliadores perfis faciais graves os casos de Classe III. Tanto as imagens de pacientes graves Classe II e Classe III, como os perfis faciais de mordida aberta e mordida profunda, foram classificados como menos atraentes. Não foram encontradas diferenças significativas na classificação geral de imagens de perfil masculino e feminino entre avaliadores do sexo feminino e masculino. Conclusão: A atratividade do perfil diminuiu na medida em que maiores eram os desvios das proporções do perfil normal e opiniões mais divergentes foram emitidas pelos avaliadores. Especialistas podem usar os resultados da percepção da beleza pelos leigos para modificar os tratamentos e, consequentemente, aumentar a satisfação dos pacientes.

ABSTRACT

Objetivo: Avaliar comparativamente o prognostico do planejamento cirurgico por software com o metodo manual. Metodo: Radiografias laterais cefalometricas e modelos de estudo pre e pos-cirurgia de vinte pacientes Classe III (12 mulheres e 8 homens, media de idade: 22,5 ± 2,3) que tinham se submetidos a cirurgia no Departamento de Ortodontia. Para o planejamento manual, com combinacao de oclusogramas pre e pos-cirurgia com radiografias cefalometricas laterais de cada paciente, foram feitas analises tridimensionais. Prognosticos da movimentacao esqueletica foram elaborados. Em seguida, mensurou-se tridimensionalmente a movimentacao esqueletica. Quinze variaveis angulares e lineares foram avaliadas e os resultados analisados estatisticamente. Para cada paciente, o prognostico manual e por software antes e apos a cirurgia foram comparados entre si. O teste t pareado foi usado para verificar possiveis diferencas (p<0,05). Resultados: Nao foram observadas diferencas entre os metodos. Conclusao: O Software Dolphin Imaging (versao 10) tem boa acuracia para a predicao do resultado pre e pos-cirurgico de cirurgias ortognaticas.


Objective: To evaluate the proximity of computer imaging soft ware surgical planning prediction methods, with standard manual methods. Method: Lateral cephalometry radiographs and study cast records of pre and post surgery of twenty longface Cl III patients (12 Females and 8 Males, mean age: 22.5 ± 2.3), that had been undergone surgery in Department of Orthodontics. For manual prediction, with combination of pre and post surgical occlusograms with lateral cephalometric radiograph tracings of each samples, three dimensional analysis was done. Predictions of skeletal movement with tacing overlay method, has prepared. Finally, measured the rate of skeletal movements at in three dimensional of spaces. Fifteen angular and linear variables were measured, and the results, analyzed using the statistical soft ware statistics. For each patient, the manual and computer soft ware prediction before and after surgery were compared with each other. The paired t-test was used to evaluate possible differences between manual and computer soft ware prediction (p<0.05). Results: The difference of the variables of the soft ware prediction in the pre and postsurgical stages in comparison with standard manual prediction method was insignificant. Conclusion: Dolphin Imaging software (version 10.0) has a good accuracy for prediction of pre and postsurgical outcome of orthognathic samples.
