Imaging in implantology /certified fixed orthodontic courses by Indian dental academy

  1. 1. IMAGING IN IMPLANTOLOGY www.indiandentalacademy.com
  2. 2. INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  3. 3. INTRODUCTION Success in implant.....??? IMAGING must provide a database that facilitates the safe placement of adequately sized fixtures in appropriate positions. www.indiandentalacademy.com
  4. 4. IMAGING OBJECTIVES Phase I  Pre-prosthetic implant imaging Phase II  Surgical and interventional implant imaging Phase III  Post-prosthetic imaging www.indiandentalacademy.com
  5. 5. 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 www.indiandentalacademy.com
  6. 6. 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 www.indiandentalacademy.com
  7. 7. 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 www.indiandentalacademy.com
  8. 8. 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 www.indiandentalacademy.com
  9. 9. ANALOG IMAGING MODALITIES Periapical radiography Panoramic radiography Occlusal radiography Cephalometric radiography Xeroradiography Radiovisiography (RVG) www.indiandentalacademy.com
  10. 10. 3-D IMAGING MODALITIES Cross-sectional tomography Computed tomography Magnetic resonance imaging TACT www.indiandentalacademy.com
  11. 11. ANALOG IMAGING MODALITIES www.indiandentalacademy.com
  12. 12. PERIAPICAL RADIOGRAPHY Indicated for single implant site Provides good detail with minimal geometric distortion Exact positioning of mental foramina Amount of bone loss and periimplantitis can be visualized Subtle variations in bone activity is clearly seen www.indiandentalacademy.com
  13. 13. www.indiandentalacademy.com
  14. 14. Limitations: Small size Not three dimensional They do not give information regarding the bucco-lingual dimension Difficult to locate the inferior alveolar canal www.indiandentalacademy.com
  15. 15. 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 www.indiandentalacademy.com
  16. 16. www.indiandentalacademy.com
  17. 17. Limitations: 2-dimensional in nature Distortion of maxilla owing to technique Not very reliable in establishing bony dimensions www.indiandentalacademy.com
  18. 18. 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 www.indiandentalacademy.com
  19. 19. www.indiandentalacademy.com
  20. 20. Limitations: Image resolution is less when compared to intra oral radiographs 6-15% image magnification can occur www.indiandentalacademy.com
  21. 21. 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., www.indiandentalacademy.com
  22. 22. www.indiandentalacademy.com
  23. 23. Limitations: Superimposition Positioning errors are more likely Resolution is comparatively less 10-20% magnification occurs- which is not uniform www.indiandentalacademy.com
  24. 24. 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 www.indiandentalacademy.com
  25. 25. Limitations: Slower speed Patient discomfort Manipulative difficulties Fragility of the thermo conductor www.indiandentalacademy.com
  26. 26. 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 www.indiandentalacademy.com
  27. 27. Limitations: Its not as flexible like a film Difficult to place in shallow palate Gagging may occur due to its thickness www.indiandentalacademy.com
  28. 28. 3-DIMENSIONAL IMAGING MODALITIES www.indiandentalacademy.com
  29. 29. CROSS-SECTIONAL TOMOGRAPHY Exact imaging of the implant site can be done Little superimposition of other anatomic structures They are least slightly magnified www.indiandentalacademy.com
  30. 30. www.indiandentalacademy.com
  31. 31. Limitations: Equipment cost Limited contrast and resolution Trained oral radiologist must be available to perform the procedure www.indiandentalacademy.com
  32. 32. 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 www.indiandentalacademy.com
  33. 33. www.indiandentalacademy.com
  34. 34. 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 www.indiandentalacademy.com
  35. 35. 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 www.indiandentalacademy.com
  36. 36. 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 www.indiandentalacademy.com
  37. 37. RECENT ADVANCES Cone beam CT Micro-tomograph Multi slice helical CT www.indiandentalacademy.com
  38. 38. 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 www.indiandentalacademy.com
  39. 39. www.indiandentalacademy.com
  40. 40. 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 www.indiandentalacademy.com
  41. 41. www.indiandentalacademy.com
  42. 42. RADIOGRAPHIC PLANNING START ADEQUATE HEIGHT YES NO UNCERTAIN www.indiandentalacademy.com ADEQUATE WIDTH
  43. 43. SUMMARY There are large number of imaging modalities available for: PLANNING SURVEILLANCE MANAGEMENT Clinicians, however, must recognize that each technique has advantages and limitations. www.indiandentalacademy.com
  44. 44. TO CONCLUDE….... “One who sees the invisible....... can do the impossible”…….!!! www.indiandentalacademy.com
