Particularmente, la posición de los incisivos centrales superiores presenta un rol importante en esta expresión y se ha sugerido el uso de referencias extracraneales para su correcta posición tridimensional. Conocer las preferencias de los distintos actores sociales respecto a este factor puede ayudar a las decisiones en la planificación de los tratamientos.  Objetivo: Evaluar la percepción estética que ortodoncistas, cirujanos dentistas y personas no expertas tienen de la sonrisa con el incisivo central superior en posición anteroposterior respecto a la frente y en norma lateral.  Métodos: Se empleó una fotografía en norma lateral en sonrisa de una mujer peruana con perfil normal y posición anteroposterior del incisivo central superior ideal según el elemento II de la armonía orofacial de Andrews. La fotografía fue modificada digitalmente de tal forma que se obtuvieron imágenes con los incisivos retruídos (- 4 mm) y protruidos (+ 4 mm). Las fotografías fueron evaluadas por un panel conformado por ortodoncistas, cirujanos dentistas y personas no expertas. La evaluación se realizó a través de una escala visual análoga.  Resultados: La fotografía con la posición normal del incisivo central superior con respecto a la línea GALL fue mejor valorada por los ortodoncistas (67,658 ± 22,094) y por los no expertos (54,038 ± 20,524). Los cirujanos dentistas consideraron más agradable la posición protruida (60,804 ± 3,626). Se encontraron diferencias significativas entre los grupos de evaluadores y las fotografías (p &lt; 0,05).  Conclusiones: Los ortodoncistas mostraron una valoración de la estética más cercana a la norma para la posición anteroposterior de los incisivos. La posición anteroposterior de los incisivos juega un rol importante en la percepción de la estética de la sonrisa en norma lateral.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT  Introduction: Orthodontic treatment is mainly aimed at achieving stable occlusal relationships and enhancing the smile expression. The position of the upper central incisors plays a particularly important role in such an expression, and extracranial references have been suggested for its proper three-dimensional position. Awareness of the preferences of the various social actors involved may be useful to make appropriate decisions when planning the treatments.  Objective: Evaluate the esthetic perception that orthodontists, dental surgeons and laypeople have of the smile with the upper central incisor in anteroposterior position with respect to the forehead and in lateral norm.  Methods: A lateral norm photograph was used of a Peruvian woman with a normal profile and ideal anteroposterior position of the upper central incisor according to element II of Andrews' orofacial harmony. The photograph was digitally modified to obtain images with retruding (- 4 mm) and protruding (+ 4 mm) incisors. The photographs were evaluated by a panel composed of orthodontists, dental surgeons and laypeople. The evaluation was based on a visual analog scale.  Results: The photograph with normal position of the upper central incisor with respect to the GALL line was ranked higher by orthodontists (67.658 ± 22.094) and laypeople (54.038 ± 20.524). To dental surgeons the protruded position was nicer (60.804 ± 3.626). Significant differences were found between the groups of evaluators and the photographs (p &lt; 0.05).  Conclusions: The esthetic appraisal of orthodontists was closer to the norm for anteroposterior position of incisors. The anteroposterior position of incisors plays an important role in the esthetic perception of the smile in the lateral norm.]]></p></abstract>
