Eazygoma technique: a new approach for zygomatic implant placement aligned with maxillomalar anatomy

Abstract This study focused on evaluating the novel Eazygoma method for zygomatic implant placement. This approach focuses on biomechanical principles, offering direct visualization that facilitates enhanced control during implant insertion. It helps prevent malpositioning, ensuring that the apical portion remains within the zygomatic body and achieves emergence in the alveolar crest through an inverted drilling sequence. The Eazygoma system enables improved control during drilling, starting in the zygomatic area and eliminating the need for osteotomies in the maxillary sinus. This not only simplifies the procedure but also significantly reduces the operative time, allowing it to be performed under local anesthesia and sedation in approximately one hour, according to the author’s experience. The study included 34 zygomatic implants placed in 11 patients with severe maxillary atrophy, treated between 2021 and 2023 at the Maxillofacial surgery Department of the private clinic “Clínica Colsanitas” in Bogotá, Colombia. To evaluate outcomes, intraoperative torque, surgical time, and whether alveolar emergence was achieved were measured for the implants. Patients were followed up at 12 months to assess implant survival. Results showed that the Eazygoma approach eliminated postoperative sinus injuries and implant malposition, ensuring alveolar emergence and achieving a torque greater than 50 Newtons in all cases, allowing for immediate implant loading.
