Multi-Planar Analysisfor Zygomatic Anchorage
Zygomatic implant planning requires specialized CBCT analysis across coronal, sagittal, and axial planes to map the 30-52.5mm trajectory from alveolar crest through maxillary sinus into the zygomatic bone body.
Multi-Planar CBCT Analysis
ZYGOMA ANATOMY MAPPING
Coronal, sagittal, and axial views reveal zygomatic bone density, thickness variations, and optimal entry points for 30-52.5mm implants.
Sinus Pathway Visualization
TRANS-SINUS TRAJECTORY
Software renders the maxillary sinus in 3D, enabling trajectory planning that minimizes membrane perforation while maximizing bone engagement.
Angulation Simulation
45-60° PLACEMENT ANGLES
Virtual implant positioning at steep angulations typical of zygomatic cases, with real-time collision detection against vital structures.
Stackable Guide Generation
CHROME CoCr OUTPUT
Planning data exports directly to CAD/CAM for manufacturing extended-length drill sleeves calibrated to zygomatic depths.
WORKFLOW
Zygomatic Planning Sequence
Zygoma Volume Assessment
CBCT segmentation isolates zygomatic bone from surrounding structures, measuring available depth (typically 12-18mm of zygoma engagement).
Entry Point Selection
Crestal or palatal emergence determined based on ridge position and prosthetic requirements for screw-access.
Trajectory Optimization
Implant path adjusted to achieve bicortical anchorage at the zygomatic buttress while avoiding orbital floor proximity.
Guide Sleeve Calibration
Extended drill sleeves (50mm+) positioned in the guide stack to accommodate zygomatic drilling sequences.
ANATOMY
Critical Structure Mapping
| Structure | Planning Consideration |
|---|---|
| Maxillary Sinus | Trans-sinus or extra-sinus pathway selection based on membrane condition |
| Infraorbital Nerve | Minimum 5mm clearance maintained during trajectory planning |
| Zygomatic Buttress | Primary anchorage zone requiring 10-15mm bone engagement |
| Lateral Orbital Wall | Trajectory angled to avoid orbital floor penetration |
| Pterygoid Plates | Secondary anchorage planned when quad-zygoma insufficient |
