The management of immature, avascular dentition with patent apices presents a therapeutic challenge. Conventional obturation techniques necessitate precise material confinement within the canalicular confines to avoid periapical extrusion. Apexification offers a solution by promoting the formation of a hard-tissue barrier, facilitating subsequent root canal filling. This case report exemplifies the application of mineral trioxide aggregate for apical plug formation, followed by definitive restoration of the compromised coronal structure with ribbond and composite.
