Por qué importa

Este estudio evalúa la proporción de alvéolos del incisivo central superior post-extracción que presentan una anatomía favorable para la emergencia palatina de un implante inmediato, permitiendo una posición adecuada para una restauración atornillada. Se analizaron casos mediante software de planificación 3D, determinando que en un porcentaje significativo de pacientes la colocación de implantes inmediatos con esta angulación deseada no es factible debido a limitaciones anatómicas o la necesidad de inclinación labial para mantener distancias biológicas seguras. La investigación subraya la importancia crítica de la evaluación preoperatoria con imágenes tridimensionales para identificar aquellos sitios que realmente cumplen los criterios anatómicos, evitando así intervenciones no predecibles y asegurando el éxito protésico.

Abstract original

The purpose of this study was to determine the prevalence of favorable anatomy for palatal emergence of an immediate flapless implant in the maxillary central incisor post-extraction site. Implants were virtually placed into maxillary central incisor sites using 3-dimensional implant planning software. Following a strict implant placement criterion to keep a safe distance to the buccal plate and other anatomical structures, sockets were assessed to determine their suitability for an implant emerging from the palatal aspect. From 321 patients included in this study, 62.3% presented a suitable socket anatomy for an immediate implant to be placed with an angulation suitable for a screw-retained crown. In 29% of the cases, the implants had to be labially tilted to maintain a minimum distance to the buccal plate; 8.7% were unsuitable for immediate implants due to anatomic limitations. The position and angulation for an immediate implant in the maxillary central incisor socket should be carefully assessed preoperatively with 3-dimensional images, as many sites will not be candidates for a palatal emergence and thus a screw-retained restoration.
