ABSTRACT
Fueron analizados los parámetros de proporción dentaria, posición del cénit gingival, posición y tamaño de las papilas interdentarias, biotipo gingival, cantidad de encía queratinizada y línea de la sonrisa en las 6 piezas anterosuperiores en 31 estudiantes de odontología chilenos. Se estableció un patrón de proporción dentaria similar al descrito previamente en la literatura. La posición de cénit presentó un patrón definido. El biotipo gingival fino fue el más frecuente. Los incisivos laterales presentaron la mayor cantidad de encía queratinizada, seguidos por los incisivos centrales y luego los caninos. La altura de la papila a nivel de los caninos fue mayor que en los incisivos centrales, mientras que los valores más bajos fueron encontrados a nivel de los incisivos laterales. Existió una predominancia de la línea de la sonrisa media.
Tooth proportion, gingival zenith position, position and size of the interdental papillae, gingival biotype, amount of keratinized gingiva and smile line position were evaluated in the 6 upper front teeth in 31 Chilean dental students. The tooth proportion pattern was similar to that described previously in the literature. The zenith position showed an established pattern. A thin gingival biotype was found more frequently. Lateral incisors showed the highest amount of keratinized tissue, followed by central incisors and then the canines. The height of the papillae at the canines was higher than central incisors, while the lowest values were found in the lateral incisors. There was a predominance of a medium smile line.

This study was performed to investigate the soft tissue changes around single implant-supported crowns during follow-up periods. Twenty patients(31 implants) whose single missing tooth in the maxillary anterior region had been replaced with an single implant-supported crown were recruited for the study. Crown length, soft tissue level and papilla height at the single implant-supported crowns were measured at follow-up examination and calculated from the slides taken at time of crown placement. as well Papilla index was scored from the slides taken at the time of crown placement and follow-up examination. A very little amount of recession occurred and the soft tissue level moved more apically and the papilla height increased significantly(p<0.01). Especially, both mesial and distal papilla index at single implant-supported crowns increased significantly during follow-up periods(p<0.001). When the two slides taken at the time of crown placement and follow-up were compared simultaneously, except one site, papillae size increased at all sites. From the results of the study, the interdental papillae at the single implant-supported crowns seemed to regenerate significantly and their crown margins were stable during follow-up periods. Hence it is indicated that various surgical interventions at on early stage to enhance soft tissue esthetics arourd single implants may be unnecessary.
