Consensus statement 4: This statement is based on 24 studies reporting treating 918 patients. Survival rates of ZI ranged between 90.3% and 100% after a follow-up of 6 months. There are many factors potentially altering the final outcomes.
Consensus statement 10: Fifteen citations report transient infraorbital nerve (V2) paresthesia, 15 studies report oro-antral communications, and 16 report peri-abutment soft tissue recession and/or hyperplasia. In six cases, a fractured ZI was described. Failure is mostly seen within the first 6 months.
Consensus statement 11: Intraoperative-specific complications of ZI malposition, orbital cavity penetration (reported in four cases in three studies; in one case with lateral rectus muscle damage), and subcutaneous peri-malar emphysema are reported.
Consensus statement 16: Maxillary sinusitis was the most reported complication. Pooled incidence rates for sinusitis in the original surgical technique (OST) were 9.5% (0–37.5%), and in Anatomy- Guided were 4.4% (0–11.8%). In most cases, sinusitis was reported by the literature without differentiation between symptomatic and asymptomatic cases. This statement is based on descriptive data of 864 patients.
