“…Volunteer selection was restricted to the following criteria: (1) untreated Class I malocclusion and Class I skeletal pattern, (2) normal findings in hard tissue cephalometric analysis (Winceph 7.0, Winceph: Rise Corporation, Sendai, Japan), and (3) normal findings in soft tissue cephalometric analysis. 33 A Canon A630 digital camera (Canon: Canon Inc, Tokyo, Japan) was used to obtain frontal smile photographs from 12 female volunteers who met the above criteria All judges were asked to rate the attractiveness of each photograph and score them using the Numeric Rating Scale (NRS), which is an assembly of categorical values divided into five groups: most unpleasant (0-50), unpleasant (50-60), acceptable (60-70), pleasant (70-90), and most pleasant (90-100). Therefore, the volunteer whose pictures scored the highest was selected as the one with the most beautiful and harmonious facial esthetics ( Figure 1).…”

Objective: To identify the ideal ratios between the widths of the maxillary arch, mouth, and face, respectively, and to determine the range of acceptable esthetic variations based on these ideal ratios. Materials and Methods: A photograph of a young female with a harmonious smile was selected and digitally altered to produce two sets of images. The first image showed an altered intercanine width, while the second one showed an altered oral fissure breadth. These alterations were independently rated by judges, including 23 orthodontists and 30 undergraduates. The MannWhitney U-test was used to compare the scores given by male and female judges and those given by professional and nonprofessional judges. Results: The following ideal transverse ratios were determined: intercanine width/oral fissure breadth, 0.638; oral fissure breadth/interparopia width: the distance between left and right paropia, 0.617; and intercanine width/face width at the level of the labial commissures, 0.300. A range of 210% to +10% was proposed as the thresholds of esthetic smile evaluations. It was shown that gender of the raters had no effect on the rating of photographs, nor were there any statistically significant differences between the professional and nonprofessional judges' ratings. Conclusions: Balanced transverse relationships in the facial region are important for smile esthetics, and there is a wide range of esthetically acceptable variations in the transverse relationships between the maxillary arch, mouth, and face.

VILLA, J.; NAVARRO, P.; ALISTER, J.P.; URIBE, F.; OLATE, S. Inclinación de incisivos maxilares en sujetos don deformidad facial de clase III. Opciones en cirugía primero. Int. J. Morphol., 34(4):1502Morphol., 34(4): -1505Morphol., 34(4): , 2016 RESUMEN: El objetivo de esta investigación es determinar la inclinación de incisivos maxilares en sujetos con maloclusión de clase III. Se incluyeron 35 sujetos que presentaran deformidad facial de clase III (DF-III) para analizar la tomografía computarizada de haz cónico; las mediciones se realizaron para los cuatro incisivos maxilares identificando el plano palatino considerado entre espina nasal anterior y posterior y el eje axial dentario obtenido por la unión entre punto coronal y punto apical; los resultados mostraron angulaciones de 111,6º a 113,7º para los incisivos, lo cual permite obtener valores cercanos a la normalidad de angulación dentaria. Se concluye que los sujetos seleccionados presentan una angulación dentaria adecuada para la realización de procedimientos de cirugía primero. PALABRAS CLAVE: Inclinación de incisivo; Mal oclusión clase III; Cirugía primero INTRODUCCIÓNLa inclinación dentaria de incisivos en el sector superior e inferior tienen un rol fundamental en la articulación y función dentaria; la oclusión tiene un papel importante en las funciones estomatognaticas, de forma que la posición y angulación dentaria puede determinar la función de un sujeto (Troy et al., 2009). En situaciones clínicas con presencia de deformidades faciales existen importantes alteraciones funcionales que relacionan la oclusión con otros factores (Pereira-Stabile et al., 2012).Las alteraciones o anomalías faciales de clase III (DF-III) se caracterizan por presentar una posición retruída de maxila y una posición adelantada de mandíbula, lo que genera graves alteraciones funcionales. Recientes investigaciones han demostrado que esta anomalía se relaciona con alteraciones nasales significativas (Olate et al., 2014;Olate et al., 2015), alteraciones en posición de sínfisis (Velásquez et al., 2015) y alteraciones en ATM (Muñoz et al., 2014a;Muñoz et al., 2014b;Goulart et al., 2015); sin duda, estas condiciones determinan la necesidad de realizar tratamientos quirúrgicos mediante cirugía ortognática y cirugía ortofacial, lo cual exige tradicionalmente el empleo de ortodoncia en las diferentes fases del tratamiento.

ÖZModern ortodontik yaklaşımda yumuşak doku paradigmasının gelişimiyle birlikte ortodontik tanı ve tedavi planlamasında tüm yüz estetiğinin incelenmesi önem kazanmıştır. Bu amaçla yumuşak doku estetiğinin değerlendirilme parametreleri konusundaki çalışmalar son dönemde ağırlık kazanmıştır. Yüze ait alın, burun, dudak ve çene ucu gibi yapıların değerlendirildiği çalışmalarda gülümseme estetiği ayrı bir başlık olarak ele alınmıştır. Sunulan çalışmada, gü-lümseme estetiği konusu ile ilgili çalışmalar ele alınıp incelenmiş ve konu derlenmiştir.Anahtar sözcükler: Estetik, Gülümseme, Ortodonti, Yumuşak doku. ABSTRACTIn the modern orthodontic approach, the investigation of face aesthetic has become more important in the orthodontic diagnosis and treatment planning with the development of soft tissue paradigm. For this purpose, studies on parameters of soft tissue esthetic evaluation have gained importance in recent years. Smile aesthetics is discussed as a separate topic in studies evaluate facial tissues like nose, lips and chin. In the present study, Studies include smile aesthetics were collected and ant the topic was revised.
