15 16 And 17 18 Gracey Fohf

  1. 1. 15/16 & 17/18 Gracey Curettes
  2. 2. 15/16 & 17/18 Gracey Curettes <ul><li>In this tutorial you will learn: </li></ul><ul><ul><li>Gracey Curettes overview </li></ul></ul><ul><ul><li>What 15/16 and 17/18 Gracey Curettes are </li></ul></ul><ul><ul><li>Features and benefits of 15/16 and 17/18 Gracey Curettes </li></ul></ul><ul><ul><li>Illustrated uses of 15/16 and 17/18 Gracey Curettes </li></ul></ul>
  3. 3. Introduction <ul><li>Gracey Curettes are area-specific to allow for deep scaling, root planing and periodontal debridement. </li></ul><ul><li>The offset blade provides perfect working angulation for the tooth surface. </li></ul><ul><ul><li>Only the lower cutting edge of each blade is used. </li></ul></ul>
  4. 4. Gracey Blade Design <ul><li>Here is an illustration showing how the Gracey blade design is offset from the shank at 70°. </li></ul><ul><li>This creates one cutting edge which is referred to as the lower edge. </li></ul>
  5. 5. Rigid Gracey Curettes <ul><li>Thicker, stronger, and less flexible shank. </li></ul><ul><li>The rigid shank is preferred for heavier calculus removal. </li></ul><ul><li>Although the shank is wider, the blade width is the same as a standard Gracey. </li></ul>Standard Rigid
  6. 6. After Five Gracey Curettes <ul><li>Designed for instrumentation in deeper periodontal pockets. </li></ul><ul><li>Elongated terminal shank (3mm). </li></ul><ul><li>Blade thinned by 10% to ease gingival insertions and reduce tissue distention. </li></ul><ul><li>Provides increased crown clearance. </li></ul>3mm
  7. 7. Mini Five Gracey Curettes <ul><li>Designed with the same elongated terminal shank (3mm) and thinned blades as the After Five Gracey Curettes. </li></ul><ul><li>50% shorter blade for access to smaller roots, narrow pockets, furcations, and developmental grooves. </li></ul>Standard After Five Mini Five
  8. 8. 15/16 & 17/18 Gracey Curettes <ul><li>In this tutorial, we will focus on the newest Graceys: </li></ul><ul><ul><li>Gracey 15/16 Mesial </li></ul></ul><ul><ul><li>Gracey 17/18 Distal </li></ul></ul><ul><li>These curettes provide the perfect complementary pair of instruments to scale difficult to reach posterior teeth. </li></ul>
  9. 9. 15/16 Gracey Curette <ul><li>The 15/16 Gracey Curette was introduced in 1993. </li></ul><ul><li>It is designed for increased access to molars, where it can be difficult to position the 11/12 Gracey Curette correctly. </li></ul><ul><li>Mesial posterior use </li></ul><ul><li>Shank bends similar to 13/14 Gracey, but with the blade offset to scale mesial surfaces of posterior teeth. </li></ul>
  10. 10. Comparison of Graceys <ul><li>The 15/16 Gracey Curette (right) has the same shank design as the 13/14 (left); however, the blade is finished like an 11/12 (center) for the posterior mesial surfaces. </li></ul>15/16 13/14 11/12
  11. 11. 15/16 Gracey Curette <ul><li>11/12 Gracey Curette – Mandibular First Molar </li></ul><ul><ul><li>It is often difficult to correctly position the shank parallel to the mesial surface using an 11/12 Gracey Curette. Notice the handle position. </li></ul></ul><ul><li>15/16 Gracey Curette – Mandibular First Molar </li></ul><ul><ul><li>The increased angle of the 15/16 Gracey Curette facilitates correct positioning (resulting in an improved scaling angle) in posterior areas . </li></ul></ul>11/12 Gracey 15/16 Gracey
  12. 12. 15/16 Gracey Curette <ul><li>11/12 Gracey Curette – Maxillary Molar - Extraoral Fulcrum </li></ul><ul><ul><li>In this region of the mouth, it is usually necessary to use an extraoral fulcrum to achieve a parallel shank angle with the 11/12. </li></ul></ul><ul><li>15/16 Gracey Curette – Maxillary Molar - Intraoral Fulcrum </li></ul><ul><ul><li>The increased angle of the 15/16 provides superior adaptation in this area, and allows the choice of an intraoral fulcrum position. </li></ul></ul>11/12 Gracey 15/16 Gracey
  13. 13. 17/18 Gracey Curette <ul><li>The 17/18 Gracey Curette is designed to improve access to the distal surfaces of posterior teeth. </li></ul><ul><li>Accentuated angles and long terminal shank allows for placement into deep periodontal. </li></ul><ul><li>The multiple bends improve the handle positioning so interference from the opposing arch is significantly reduced. </li></ul><ul><li>Reduced blade length enhances adaptation of the entire blade to the tooth. </li></ul>
  14. 14. Comparison of Graceys <ul><li>The accentuated angles on the 17/18 (far right) are its most distinguishing feature. </li></ul><ul><li>These angles improve crown clearance and handle positioning so that access to the distal surfaces of second and third molars is greatly increased. </li></ul>13/14 13/14AF 17/18
  15. 15. 17/18 Gracey Curette <ul><li>The terminal shank is almost as long as an After Five Gracey, which increases access in periodontal pockets. </li></ul><ul><li>The blade is 1mm shorter than standard Gracey blades which enables adaptation of more of the blade to the tooth. </li></ul>13/14 After Five 17/18 Gracey Terminal Shank and Blade Comparison 13/14 After Five and 17/18 Gracey Curette
  16. 16. 17/18 Gracey Curette <ul><li>13/14 Gracey Curette </li></ul><ul><ul><li>Access to the distal surface of a second molar is limited by interference from the opposing arch and the patient’s ability to open widely. </li></ul></ul><ul><li>17/18 Gracey Curette </li></ul><ul><ul><li>With the 17/18’s multiple bends, the handle position is closer to horizontal which minimizes the contact with the opposing arch. Allowing the clinician improved access to difficult to reach posterior areas. </li></ul></ul>13/14 Gracey 17/18 Gracey
  17. 17. 17/18 Gracey Curette <ul><li>17/18 Gracey Curette on Mandible (Skull) </li></ul><ul><ul><li>Access is improved through the multiple exaggerated bends of the 17/18. </li></ul></ul>17/18 Gracey
  18. 18. 17/18 Gracey Curette <ul><li>17/18 Gracey and 17/18 Rigid Gracey Curettes </li></ul><ul><ul><li>The 17/18 is available in Standard (on left) and Rigid (on right) designs. </li></ul></ul><ul><ul><li>The rigid shank is thicker, providing additional strength for heavy calculus removal. </li></ul></ul>Standard Rigid
  19. 19. 17/18 Gracey Curette <ul><li>Comparison of Gracey 17/18, 15/16 and After Five 15/16 </li></ul><ul><ul><li>The 17/18 Gracey (right) is the ideal companion to the 15/16 Gracey (left) or the 15/16 After Five (center). </li></ul></ul><ul><ul><li>These instruments improve access to the most difficult to reach posterior teeth. </li></ul></ul>17/18 15/16AF 15/16
  20. 20. Available Designs <ul><li>17/18 Available in: </li></ul><ul><ul><li>- Standard - Rigid </li></ul></ul><ul><li>15/16 Available in: </li></ul><ul><ul><li>Standard - Rigid - After Five ® - Mini Five ® </li></ul></ul>Mini Five ® After Five ® Rigid Standard
  21. 21. Summary <ul><li>The Gracey 15/16 Mesial and 17/18 Distal curettes provide the perfect complementary pair of instruments to scale difficult to reach posterior teeth. </li></ul><ul><li>15/16 </li></ul><ul><ul><li>Shank bends similar to the Gracey 13/14 but with the blades offset to scale mesial surfaces of the posterior teeth. </li></ul></ul><ul><li>17/18 </li></ul><ul><ul><li>Accentuated shank angles and long terminal shank for deep perio pockets. </li></ul></ul><ul><ul><li>Reduced blade length. </li></ul></ul><ul><li>Available in: </li></ul><ul><ul><li>Standard: SG15/16 & SG17/18 </li></ul></ul><ul><ul><li>Rigid: SGR15/16R & SGR17/18R </li></ul></ul><ul><ul><li>After Five (15/16 only): SRPG15/16 </li></ul></ul><ul><ul><li>Mini Five (15/16 only): SAS15/16 </li></ul></ul><ul><ul><li>#2,4,6,7,8, & 9(EverEdge) </li></ul></ul>
