Title: 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

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

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

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

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
