Por qué importa

Este caso clínico aborda la complicación derivada de la colocación simultánea de implantes y elevación del seno maxilar, específicamente la migración de un implante al interior del mismo. La publicación detalla la resolución de este incidente mediante un abordaje intraoral, una técnica relevante para los clínicos que se enfrentan a la escasez de volumen óseo en la zona posterior del maxilar. La descripción del procedimiento de extracción y las consideraciones para facilitar el desplazamiento del implante a una zona de extracción más favorable, como dormir de lado, ofrecen información práctica. Comprender estas estrategias es crucial para manejar adecuadamente las complicaciones en la implantología maxilar y optimizar los resultados de tratamientos en casos de regeneración ósea.

Abstract original

BACKGROUND: The replacement of maxillary posterior teeth often challenges the clinician due to bone resorption after dental exodontia and low bone quality. Currently, attempts are being made to shorten treatment times by placing implants simultaneously to sinus lift procedures in borderline cases, which can lead to complications such as displacement of implants into the maxillary sinus. CLINICAL CASE: A 54-year-old patient who was planned for complete rehabilitation of the maxilla through a fixed implant-supported prosthesis on 6 implants. At the level of the 3rd sextant, a sinus lift was performed with a lateral window approach (Caldwell-Luc type) and the simultaneous placement of two implants, one of which migrated into the sinus. The implant was displaced after 4 months when the second stage (uncovering) implant surgery was performed for the connection of the healing abutments. The implant was removed a week after the migration, since it had moved to the tuberosity area in the sinus and the lateral window had been performed in a more mesial position, so the patient was recommended to sleep on the right side to achieve the displacement of the implant to a more favourable area, removing it after a week through the same approach. DISCUSSION: Surgical strategies for the removal of a migrated implant are essentially divided into two main approaches: endoscopic transoral and endoscopic transnasal (and combined). CONCLUSIONS: Dental implant complications, dental implant, dental implant displacement, maxillary sinus, case report.
