Customized Surgical Approach Using The Zygoma Anatomy-Guided Approach (Zaga) Technique For Zygomatic Implant Placement: A Case Report

Abstract

The rehabilitation of severely atrophic maxillae represents a major challenge in contemporary implant dentistry. Zygomatic implants have emerged as a predictable alternative to bone grafts, allowing immediate rehabilitation and functional stability. This case report describes the placement of zygomatic implants using the Zygoma Anatomy-Guided Approach (ZAGA), which enables a personalized surgical technique according to each patient’s anatomy. The procedure was performed under general anesthesia with an intraoral approach, virtual planning, and the use of a 3D-printed anatomical model. Two conventional implants were placed in the anterior region and two zygomatic implants—one with an extra-sinus path and another intra-sinus. The postoperative period was uneventful, showing excellent stability and satisfactory aesthetic and functional results. The ZAGA technique proved to be effective and safe, reducing sinus complications and improving prosthetic positioning. It is concluded that the careful use of zygomatic implants, combined with digital planning and precise execution, represents a predictable and efficient solution for the immediate loading rehabilitation of atrophic maxillae.
