3. IMAGING OBJECTIVES
Phase I Pre-prosthetic implant
imaging
Phase II Surgical and interventional
implant imaging
Phase III Post-prosthetic imaging
4. PRE-PROSTHETIC IMAGING
Determines bone quality, quantity and
angulation of bone
Relationship of the critical structures
The presence or absence of disease at
the proposed site
5. SURGICAL & INTERVENTIONAL
IMPLANT IMAGING
Evaluates the sites during and
immediately after surgery
Assist in the optimal position and
orientation of dental implants
To ensure abutment position and
prosthesis fabrication
To evaluate healing
6. POST-PROSTHETIC IMAGING
To evaluate the long-term maintenance
of implant rigid fixation and function
Crestal bone levels around each implant
To evaluate the implant complex
7. IMAGING MODALITIES
The decision to image the patient is based
on the patients clinical needs and its
availability.
Imaging modalities can be:
Analog imaging modalities
Three –dimensional imaging
modalities
11. PERIAPICAL RADIOGRAPHY
Indicated for single implant site
Provides good detail with minimal
geometric distortion
Exact positioning of mental foramina
Amount of bone loss and peri-
implantitis can be visualized
Subtle variations in bone activity is
clearly seen
12.
13. Limitations:
Small size
Not three dimensional
They do not give information regarding
the bucco-lingual dimension
Difficult to locate the inferior alveolar
canal
14. OCCLUSAL RADIOGRAPHY
Larger area of coverage
Shows the bucco-lingual dimensions
External and internal diameter of the
healing socket is clear
Circumferential bone activity can be
visualized more clearly by occlusal view
17. LATERAL CEPHALOMETRICS
Images are obtained with the mid
sagittal plane
Provides more accurate information on
inclination, height and width of alveolar
bone at the midline
Relationship of the jaws in occlusion can
be obtained
20. PANORAMIC RADIOGRAPHY
Indicated when multiple implants are
planned
Larger area of coverage
General view of bone anatomy
Can see anatomic structures such as
foramina, sinuses, etc.,
23. XERORADIOGRAPHY
Images have a superior resolution
Good detail due to edge enhancement
Vascular margins are better visualized
Trabecular detail of the bone is better
Good image quality
Cost effective
25. RADIOVISIOGRAPHY
All the procedures can be visualized almost
immediately
Any area of the picture can be enlarged
Provides necessary magnification
Good resolution
Conventional developing is not necessary
Bone pattern, its height and depth during
implant placement can be visualized
26. Limitations:
Its not as flexible like a film
Difficult to place in shallow palate
Gagging may occur due to its thickness
31. COMPUTED TOMOGRAPHY
…..DENTA SCANS…..
Used for imaging multiple implant sites
Precise estimation of bone levels
Automatic calculation of bone height
and width
Reconstruction of image is possible
Can produce images in any plane
High contrast and fine detail
32.
33. Limitations:
Software must be available at hospital
radiology service
Access must be provided to CT unit
Patients head position must remain
constant during imaging
Equipment cost
34. MAGNETIC RESONANCE
IMAGING
MRI can sharply delineate soft and
hard tissues
Can differentiate between cortical and
cancellous bone
‘Zero radiation dose’
Good soft tissue details
35. Limitations:
At present no special software is
available for specific use in implantology
Its application in implantology is still in
its experimental phase
Expensive tool
37. TUNED APERTURE COMPUTED
TOMOGRAPHY
The beam passes through an object from
several different angles
Can isolate images of desired structures
limited to certain depth
Good contrast and resolution
It has the ability to accommodate
patients motion between exposures
38.
39. SIMPLANTS
Simplant is an interactive dental
implant software package
It allows dentists to view and
manipulate processed CT images
Simplant software can be used to
superimpose images of actual size
implants on the CT images for
treatment planning
42. SUMMARY
There are large number of imaging
modalities available for:
PLANNING
SURVEILLANCE
MANAGEMENT
Clinicians, however, must recognize
that each technique has advantages and
limitations.
