Purpose:
To present a novel protocol of sinus lateral window preparation and simultaneous dental implant placement using an autonomous robotic system.
Materials And Methods:
The novel protocol consists of (1) preoperative data acquisition: cone beam computed tomography (CBCT) and intraoral scan; (2) preoperative design and surgery planning; (3) marker design, fabrication, and fixation; (4) registration and calibration; (5) osteotomy of the lateral window by a robotic system and elevation of the sinus membrane; (6) implant osteotomy simultaneously performed by an autonomous robotic system; (7) bone augmentation and implant placement; and (8) postoperative procedures: CBCT acquisition and accuracy assessment, if applicable.
Result:
The protocol was an effective method for sinus lateral window preparation and simultaneous dental implant placement, with no reported intraoperative complications. Meanwhile, this technique exhibited exceptional control in depth during the creation of the lateral window, with the minimum deviation reached within 0.04 mm in a case. The trueness of the window site and implant placement was clinically acceptable.
Conclusions:
The autonomous robotic surgery demonstrates potential as a viable alternative to conventional freehand techniques for sinus lateral window preparation and dental implant placement. Conceptual validation indicates this approach may enhance precision, minimize invasiveness, and reduce complication risks. Further clinical studies are warranted to confirm the efficacy and safety of the protocol.
