Immediately loaded fixed full-arch implant-retained prosthesis: a solution to the extreme defect in zone 2—a case report

Abstract

Abstract Background Implants immediately loaded full-arch prosthesis in maxilla is always a challenge, especially when the zone 2 is extremely defected. To achieve a satisfying result, different therapeutic alternatives have been proposed, such as zygomatic implant, pterygoid implant; however, precise surgical skills limited its application. Case presentation This study reported a case that an edentulous patient was treated with a new technique, two axial implants and four tilted implants supporting an immediate fixed denture, extruding the cortical bone of the anterior wall of the maxillary sinus to establish the primary stability. Conclusions Two-year follow-up proves that it is a viable choice. Meanwhile, a reliable method for its saving time and money and low level of discomfort for patients is presented.
