The ZAGA method originated from a need to offer patients with severe maxillary atrophy reliable, long-term solutions without the adverse effects of the original technique (sinus complications and bulky prostheses) and without the typical complications of exterior or extra-sinus techniques (gingival dehiscence and exposure of the zygomatic implant).
The ZAGA method was explained by Dr. Aparicio in his book “Zygomatic Implants. The Anatomy-Guided Approach” (ZAGA). After a series of surgical and anatomical studies with actual patients, Dr. Carlos Aparicio further developed the extra-maxillary technique for placing implants proposed by his own group in 2005. These contributions helped prevent gum recession and the presence of gaps in the gums surrounding the zygomatic implant. In 2011, based on a systematic classification of maxillary anatomy, he proposed a system for providing individualized treatment plans for each patient, known as ZAGA. The objective of these plans was to prevent the complications of previous techniques, which used similar surgical procedures for all patients.
