Zygomatic implant (ZI) is an option of the edentulism. Complications associated with ZI are maxillary sinusitis and soft tissue recession. The Zygoma Anatomy-Guided Approach (ZAGA), reduce the complications of the Original zygomatic intra-sinus Surgical technique (OI-ST). Study Aims: 1) report and compare the prevalence of sinus complications between ZAGA and OI-ST. 2) propose therapeutic guidelines for sinus. Material and Methods: ZAGA has been proposed to reduce the complications of the OI-ST. Results: Statistically significant increase of the "Modified Lund Mackay" (MLM) score (was noted in CT of patients after ZI surgery in comparison with the pre-surgical Lund-Mackay (LM) score (t=5, 0, p<.0005). Our study indicates that patients who underwent the ZI surgery according to the OI-ST. (M = 2.93, SD = 3.65) demonstrated a significantly higher ML-M score (t = 2.99, p < .003) compared to the patients operated with the ZAGA Concept (M = 1.52, SD = 2.36). Conclusions: ZI procedures can lead to sinus alterations. Significant differences have been found between two different approaches.
