3D Diagnostics in Dental Office

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

Radiation dose

• The radiation dose in CBCT
• same level as 10 panoramic images
• less than full mouth series
• essentially less than in medical CT

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

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

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

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
