Autogenous Trephine Core Sinus Lift and Simultaneous Implant Placement: A Case Report

This article describes a case of indirect sinus lift augmentation using autogenous trephine alveolar bone cores and simultaneous placement of dental implants in a highly resorbed posterior maxillary region. In comparison to the direct sinus lift approach, the procedure described in this case report is less invasive, results in reduced treatment time, and yields a more predictable outcome. This procedure involves a mucosal incision followed by surgical exposure of the alveolar bone, and then using a trephine drill to create a bone trephine core. The Schneiderian membrane is then gently pushed up along with the bone trephine core using an osteotome and mallet, followed by simultaneous dental implant placement. Although this technique is skill-sensitive, it results in successful osseointegration of the implant with fewer complications.
