Digital Scanning Troubleshooting
Scan body not recognized by software
Verify scan body is correct brand/model for your implant. Ensure full 360° capture. Clean scan body surface. Update scanner software to latest version.
Mesh holes or artifacts around scan bodies
Slow down scan speed around scan bodies. Ensure field is dry. Re-scan the affected area. Use scanner's 'fill holes' or 'repair mesh' tool.
Bite registration doesn't align
Have patient bite into stable centric occlusion. Scan buccal corridor with teeth in contact. Use articulating paper to verify contacts before scanning.
Full arch scan drifts or distorts
Scan in segments and verify alignment at each step. Use anatomical landmarks as reference points. Consider a verification jig for 4+ implant cases.
STL file rejected by lab software
Check file size (should be 5-50MB for a full arch). Verify export settings match lab requirements. Try exporting in a different format (PLY, OBJ). Contact scanner support.
Scan body position doesn't match clinical reality
Verify scan body was fully seated during scanning. Take a verification radiograph. Re-scan with new scan body if damaged. Use a scan body seating jig.
