Zygomatic Implant
Pronunciation: zy-go-MAT-ik
Also written as: ZI — Zygomatic Implant
An extra-long dental implant anchored in the zygomatic bone (cheekbone) rather than the alveolar ridge, used in cases of severe maxillary bone atrophy.
Full Definition
Zygomatic implants (ZIs), originally developed by Per-Ingvar Brånemark, are typically 30–52 mm in length and pass through the maxillary sinus to engage the dense cortical bone of the zygoma, providing stable anchorage when alveolar bone volume is insufficient for conventional implants. Editors should be aware of the alternative spellings 'zygomatic' vs. the less common 'zygomaticus', and should note that 'Zygoma Implant' is a registered trade term used by some manufacturers. Clinical descriptions of ZI placement require precise anatomical vocabulary (Zygoma anatomy, sinus slot vs. extrasinus technique). Complication terminology specific to ZIs, such as sinusitis, oro-antral communication, and soft-tissue dehiscence, should be accurately represented.
Usage
Usage note: When 'Zygoma Implant' appears in a manuscript, verify whether the author means the generic technique or the Nobel Biocare proprietary system, and adjust capitalisation accordingly.
In Context
- "Four zygomatic implants were placed using the extrasinus technique to rehabilitate the fully atrophic maxilla." — Surgical case series
- "The paper must differentiate between zygomatic implants and pterygoid implants, as both are used in atrophic posterior maxillae but anchor in distinct anatomical structures." — Editorial review comment
