Abstract Introduction The objective of the study was to provide long‐term clinical outcomes and complications in severely atrophic edentulous maxillae treated by means quad zygoma protocol (QZP) using Anatomy‐Guided Approach (AGA). Methods This a retrospective cohort all consecutive patients with maxilla insufficient bone height width anterior posterior regions bilaterally, who underwent rehabilitation QZP between May 2006 December 2021. All were followed for at least 1 year. zygomatic implants (ZIs) placed same surgeon. primary endpoint implant survival rate. Secondary endpoints success rate, prosthesis complications, Oral Health‐Related Quality Life OHIP‐14 questionnaire. Results A total 56 (men 16, women 40) 224 ZIs (Nobel Biocare, n = 204; Straumann, 16; Southern Implant, 4) placement included mean follow‐up period 8.8 ± 3.9 years (range, 1.2–17.0). (success) rate 97.7%. Five four failed. time failure 8.6 0.5–13.3). received immediate loading acrylic prosthesis. successful rates definitive 98.2%.

In 48 patients, score questionnaire 1.7 2.6 9.0 4.1 years. Conclusions has shown predictable high long term. implementation an offers potential benefits stabilizing cross‐arch stabilization. Moreover, use reconstruction can effectively establish functional occlusion through well‐distributed ZIs, eliminating need additional placement.
