  1. 3D Diagnostics in Dental Office major step in digital imaging

  2. ProMax 3D Technology • CBCT - Cone Beam Computed Tomography • CBVT - Cone Beam Volume Tomography • 3D image volume is a cylinder • 8 cm diameter • 8 cm high image data is a cylinder, not a single X-ray image

  3. ProMax 3D Technology • 3D volume anywhere in dental anatomy • 20 seconds scan • 200+ images taken during the scan • The images are converted to voxels with a proprietary reconstruction algorithm • Cylinder consists of over 100 million voxels 300 images converted into voxels

  4. ProMax 3D Technology • Images taken using short X-ray pulses during the scan • Stroboscopic effect • Enhanced clarity of the images • Reduced radiation dose Pulsed X-ray saves radiation

  5. ProMax 3D Technology • Flat panel type semiconductor based X-ray sensor • High sensitivity and resolution • Distortion free and reliable • No aging with loss of sensitivity and contrast as image intensifier • No geometric distortion as II modern flat panel X-ray sensor – distortion free images

  6. Radiation dose • The radiation dose in CBCT • same level as 10 panoramic images • less than full mouth series • essentially less than in medical CT Dig. Pan 4.7-14.9 uSv FMS 150 uSv Dr Sharon Brooks, O of Michigan Medical CT 1200-3300 uSv Dr Stuart White, UCLA Low radiation dose compared to medical CT

  7. Extended applications • Unique new imaging capabilities for: • implant planning • oral surgery • impacted teeth • 3rd molar extractions • occlusion analysis • TMJ analysis • periodontics • airway studies • Emerging new diagnostic applications • ongoing university research new diagnostic possibilities – in dental office

  8. Cephalometry and ProMax 3D • Promax 3D is not aimed for 3D cephalometric imaging • Promax Digital Ceph ideal for cephalometry • adequate information for all orthodontic planning • lower radiation dose for young patients • less time consuming procedure • 3D to be used for detailed occlusion views if needed for orthodontic planning • same Promax unit for both studies Promax 3D with digital pan/ceph- optimum for orthodontic imaging

  9. 3D viewing • 3D volume viewing: • sagittal, coronal, axial views simultaneously • interactive realtime viewing of all projections • contrast & brightness sagittal coronal axial adjustable viewing projections

  10. 3D viewing • Pseudo panoramic view: • focal through path defined by user on axial view • layer thickness selectable and constant • no redundant shadows or artefacts • constant magnification • Cross sectional cuts of mandible and maxilla • interactively adjustable offsets and angles • constant magnification refined conventional views

  11. standard panoramic image redundant shadows

  12. pseudo panoramic image calculated from 3D data

  13. 3D viewing • Measurements • point-to-point distances in 3D • point-to-point angulation in 3D • Implant planning • expandable implant library with preferred types • implant site planning in 3D volume • planning visible in all views • colour marking absolute accuracy

  14. 3D DICOM • DICOM Dir, DICOM Storage • transferring studies • (DICOM Print, not in 1st version) • eg. printing panoramic + cross sectional views • enables image viewing and processing using 3rd party softwares: • implant planning • robotic dental navigation • image rendering 3D image transfers via DICOM

  15. 3rd Party software through DICOM • Implant planning, eg. • Simplant • Nobelguide • Cybermed V-implant • med3D • Dental navigation, eg. • Robodent • Image rendering, eg. • Vworks • Amira expanded capabilities through 3rd part software

  16. Planmeca ProMax configurations • Promax film pan • Promax film pan/ceph • Promax digital pan • Promax digital pan/ceph • Promax 3D • Promax 3D with digital pan • Promax 3D with digital pan/ceph • fully field upgradable advances in digital imaging

  17. ProMax 3D upgrade • All ProMax units can be upgraded to 3D • extent of the upgrade depends on the serial number • 3D upgrade consists of: - new 3D sensor - new ProMax patient support - new ProMax software - computer including 3D software all ProMax units can grow to 3D

  18. ProMax 3D timing • Availability estimation: pilot installations in various countries starting Q2/2006 • Subject to results of clinical test • Subject to regulatory approvals • Rights for changes reserved ProMax 3D is still works in progress – not a deliverable product, yet
