Perio. instrumentation

  1. 1. Perio I ( pre-clinic periodontology course ) By /shaker al.samea periodontal instrumentation
  2. 2. 1. Periodontal probes. 2. Scaling and root planning instruments. 3. Polishing instruments. 4. Periodontal surgical instruments. 8-Sep-13 2
  3. 3. Periodontal probes 8-Sep-13 3
  4. 4.  Function : to measure the depth of the pockets.  General characteristics : - tapered - straight - millimeter calibration - blunt, rounded tip - thin ( 0,5 mm at the end ) - the shank is angled to allow easy insertion in the pocket. 8-Sep-13 4
  5. 5. 8-Sep-13 UNC-15 : • a 15-mm-long probe with markings at each millimeter • Color coding between 4-5 mm, 9-10 mm, 14-15 mm . • very useful in periodontal research Types of periodontal probes UNC-15
  6. 6. 8-Sep-13 6 Williams probe  Williams marking at : 1, 2, 3, 5, 7, 8, 9,10 mm Williamsprobe
  7. 7. 8-Sep-13 Williams Goldman-Fox - Goldman-Fox probe same as Williams probe`s calibration - But it is flattened not round
  8. 8. 8-Sep-13 CP 12-S CP11 CP12 All of them color-coded CP 12 : 0,3 mm at the end ( tip ) CP 12-S: modified/0,5 mm ball at the end/ Calibrations in 3-mm sections
  9. 9. 8-Sep-13 WHO probe • 0,5 mm ball at the tip • millimeter markings at 3,5/ 5,5/ 8,5/ 11,5 mm • color coding from 3,5 to 5,5 mm WilliamsWHO CP12
  10. 10. Nabers probe :  Curved  Blunt for furcation areas  we can detect the furcation areas also with straight probe. 8-Sep-13
  11. 11. 8-Sep-13 11 Scaling and root planning instruments
  12. 12. instrument design 8-Sep-13 12 Parts of each instrument Working end ( blade ) Shank handle
  13. 13. The blade at the same level with the handle. Different handles, Diameter range between 5 to 10 mm 8-Sep-13 13
  14. 14. From A to B is the shank (The lower part is Terminal shank ) functional shank length 8-Sep-13 14

  18. 18. 8-Sep-13 18
  19. 19.  Sickle scaler  Curette  File  Chisel not more be used  hoe 8-Sep-13 19 Types of scaling and root planning instrument
  20. 20.  Characteristics ( design ) : 1.Triangular shape in cross section . 2.Two cutting edges . 3. pointed tip . 3.The angle between the blade and terminal shank is 90 8-Sep-13 20 Sickle scaler
  21. 21. Function :  It is used primarily to remove supragingival calculus  Some sickle scalers are small , curved , thin enough to be inserted a few mm below the gingiva . 8-Sep-13 21
  22. 22. Types of scalers 1)- Different blade size. 2)- Different blade design curved, or straight . 3)- Different shank type : - Straight shanks are designed for use on anterior teeth and premolars. - Angled shanks adapt to posterior. 8-Sep-13 22
  23. 23. 8-Sep-13 204 S C103 CK6 Crane-Kaplan Sickle scalers angled shank, curved blade, different blade sizes
  24. 24. Curved or straight sickle scalers ? 8-Sep-13 24
  25. 25. 8-Sep-13 U15 CK6
  26. 26. General characteristics ( design ) : 1. Rounded toe, no sharp points, can be inserted into deep pockets with minimal soft tissue trauma. 2. In cross section , the blade appear semicircular ( spoon-shaped blade ) 3. Fine blade. 4. Curved blade. 8-Sep-13 26 curettes
  27. 27. Function :  Removing deep subgingival calculus  Root planning Two basic types :  Universal.  Area-specific. 8-Sep-13 27
  28. 28.  The face is at a 90-degree angle with terminal ( lower ) shank.  Two cutting edge.  What is the difference between universal Curette and sickle scaler? 8-Sep-13 28 Universal curettes
  29. 29. -Universal curettes- Columbia curettes 8-Sep-13 29
  30. 30. 8-Sep-13 Columbia: 2R/2L 4R/4L
  31. 31.  Gracey curettes are a set of several instruments designed to adapt to specific anatomic areas of the dentition.  The best instruments for subgingival scaling and root planning because : - they provide the best adaptation to complex root surface anatomy. - only one cutting edge, less damage to the gingival soft tissues. 8-Sep-13 31 Area-specific curettes ( Gracey curettes )
  32. 32. 1. Blade is at 70 degrees from the lower shank (offset blade). This angulation allows the blade to be inserted in the precise position , provided parallel lower shank with the long axis of the tooth surface being scaled. 8-Sep-13 32 Design of Gracey curette
  33. 33. 2. Curved blade in two planes blade curves up and to the side 3. One cutting edge. 8-Sep-13 33
  34. 34. Universal curetteGracey curette All areas and surfacesspecific surfacesArea of use two cutting edgeOne cutting edgeUse of cutting edge Curved in one planeCurved in two planesCutting edge curvature Not Offset , 90 degreesOffset blade, 70Blade angle 8-Sep-13 Universal curetteGracey curette
  35. 35. 8-Sep-13 35 • Larger, stronger, and less flexible shank and blade • Used to remove moderate- to-heavy calculus Rigid design(A) • Thinner shank, more flexible, • Enhanced tactile sensitivity, used to finish root planning. Finishing design (B) Rigidity type of shank
  36. 36.  Gracey # 1-2 and 3-4 : anterior teeth.  Gracey # 5-6 : anterior teeth (and premolars).  Gracey # 7-8 and 9-10: posterior teeth : facial and ligual.  Gracey # 11-12 : posterior teeth : mesial  Gracey # 13-14 : posterior teeth : distal . 8-Sep-13 36 Double-ended Gracey curettes are 7 instruments
  37. 37. 8-Sep-13 Standard Gracey Curettes
  38. 38. Reduced set of Gracey 8-Sep-13 38 # 5-6 # 7-8 # 11-12 # 13-14
  39. 39.  It is a modification of the standard 11-12  Combines a Gracey : #11-12 blade with a #13-14 shank .  It is allows better adaptation to posterior mesial surfaces, especially on the mandibular molars with an intraoral finger rest. 8-Sep-13 39 Gracey #15-16
  40. 40. 8-Sep-13 40 • They are modifications of the standard Gracey curette design. New features : 1. The terminal shank is 3 mm longer ( allowing extension into deeper periodontal pockets of 5 mm or more). 2. A thinned blade . For smoother insertion , and reduced tissue stretching. 3. 1mm shorter blade extended shank instruments - After Five curette -
  41. 41.  Available After Five instruments : #1-2, 3-4, 5-6, 7-8, 9-10 , 11-12, 13-14  Available in finishing (fine) or rigid designs: - rigid After Five Gracey curettes - finishing After Five Gracey curettes 8-Sep-13 41
  42. 42. Gracey curettes for posterior proximal surfaces mesial surfaces distal surfaces 8-Sep-13 42
  43. 43.  Rigid standard #13-14 adapted to the distal surface of the first molar. And rigid After Five #13-14 adapted to the distal surface of the second molar.  Notice the extra long shank which allows deeper insertion and better access. 8-Sep-13 43
  44. 44. They are modifications of the After Five curettes Features: 1. Blades are half the length of the After Five or standard Gracey curettes. 2. Extended shank 8-Sep-13 44 Mini-bladed curettes - Mini Five-
  45. 45. Function Easier insertion and adaptation in any area where root morphology or tight tissue prevents full insertion of standard Gracey or After Five blade : 1. deep, narrow pockets, 2. furcations, 3. developmental grooves, 4. line angles, 5. Deep, tight pockets. 8-Sep-13 45
  46. 46. Comparison of a standard Gracey # 5-6 with a Mini Five # 5-6 curette on the palatal surfaces of the maxillary central incisors. The Mini Five can be inserted to the base of these tight pockets with vertical stroke. 8-Sep-13 46
  47. 47. - Available in both: - rigid Mini Five Gracey curette - finishing Mini Five Gracey curette - available in all standard Gracey numbers except for the # 9-10 - advantages : 1. can be used easily with vertical strokes, 2. With reduced tissue distention, 3. and without tissue trauma. 8-Sep-13 47
  48. 48.  Plastic instruments be used to avoid scratching and damage to the implants. 8-Sep-13 48 Plastic instruments for implants
  49. 49. 8-Sep-13 49 Oscillating scaler Ultrasonic sonic Used to remove plaque, Calculus, stains. Oscillating scaler systems - power-driven scalers-
  50. 50.  The vibrations range from 20000 to 45000 cycle/second. 8-Sep-13 50 ultraonic scaler
  51. 51. 8-Sep-13 51  Consists of a handpiece that attaches to compressed air in dental unit.  Vibrations at the sonic tip range from 2000 to 6500 cycle per seconds ( Hz ) . Sonic scaler
  52. 52. 8-Sep-13 52 Polishing instruments

  54. 54.  Used in the handpiece with paste.  There is disposable plastic prophylaxis angle and rubber cup, may be used and then discarded. 8-Sep-13 54 Rubber cup
  55. 55.  Are available in wheel and cup shapes.  Is used in the handpiece with a polishing paste.  Should be used with low speed . 8-Sep-13 55 Bristle brushes
  56. 56. 8-Sep-13 56 Periodontal surgical instruments
  57. 57. 8-Sep-13
  58. 58. Instruments will be used in Perio I 8-Sep-13 58 - blade 15 ( 2 pieces ) - scalpel - silk suture (000) - needle holder - periodontal probe - U15/30 , CK6 , or another fine sickle scalers available in dental market ( like H5/33 , H6/H7 , … ) - Gracey curettes : / 5-6 / 7-8 / 11-12 / 13-14 / - toothbrush
