Study Reveals Malar Bone Implant Engagement in Zygomatic Implants by ZAGA Classification

Posted: September 6, 2025
A retrospective study examined the bone implant engagement (BIE) of 100 zygomatic implants (ZIs) at the malar bone level and its correlation with the ZAGA classification. The study, conducted on 32 patients with severe maxillary atrophy, assessed 80 ZIs placed in pairs and 20 as single ZIs using a fully digital protocol. Results showed a significant relationship between mean BIE and ZAGA classification, with variations based on implant position and anatomy. The mean BIE was lowest in ZAGA 0 and ZAGA 4, increasing from ZAGA 1 to ZAGA 3. Three-dimensional analysis revealed detailed measurements of BIE, emphasizing the impact of implant location on bone engagement.
