SYSTEMATIC REVIEW OF ZYGOMATIC IMPLANT SUCCESS RATES IN THE REHABILITATION OF SEVERELY ATROPHIC MAXILLAE

Zygomatic implants offer an effective treatment option for patients with severe maxillary atrophy, enabling the delivery of fixed prosthetics within 24 hours. Despite their widespread use, reported success rates vary across studies, leading to ongoing debate regarding their overall efficacy and predictability. This study aims to evaluate the published literature on the use of zygomatic implants for reconstructing the severely atrophic maxilla and to report the cumulative success rate (CSR) over various follow-up periods. A systematic review of 196 studies was conducted, revealing a CSR of 98.5% at less than 1 year, 97.5% at 1–3 years, 96.8% at 3–5 years, and 96.1% after 5 years or more. The most frequently reported complications were soft tissue dehiscence, rhinosinusitis, and prosthetic failures. These findings confirm that zygomatic implants are a reliable and safe solution for addressing severe maxillary bone deficiency, achieving a CSR of 96.1% over the long term.
