Transcript of "Curettes Clinical Application Guide"

  1. 1. Curettes Clinical Application Guide
  2. 2. Curettes <ul><li>In this tutorial you will learn: </li></ul><ul><ul><li>Types of curettes </li></ul></ul><ul><ul><li>Curette blade designs </li></ul></ul><ul><ul><li>Curette instrumentation </li></ul></ul><ul><ul><li>Clinical uses of curettes </li></ul></ul>
  3. 3. Types of Curettes <ul><li>A curette is a type of scaler that is designed for moderate calculus removal on supragingival and subgingival surfaces. </li></ul><ul><li>Types of Curettes: </li></ul><ul><ul><li>Universal </li></ul></ul><ul><ul><li>Area Specific (Gracey) </li></ul></ul><ul><li>All curettes share the same common elements: </li></ul><ul><ul><li>Rounded back </li></ul></ul><ul><ul><li>Rounded toe </li></ul></ul><ul><ul><li>Semi-circular cross section </li></ul></ul>
  4. 4. Curettes Universal Curettes
  5. 5. Universal Curettes <ul><li>Universal curettes are designed for easy adaptation on all tooth surfaces (thus the name “universal”). </li></ul>
  6. 6. Universal Curettes <ul><li>The blade of a universal curette has a round toe and back, and two cutting edges for scaling, making it an efficient design for scaling the entire mouth. </li></ul>Toe Face Cutting Edge Lateral Side Back 90 °
  7. 7. Universal Instrumentation <ul><li>The blade is correctly adapted when the toe is directed interproximally and the terminal shank is parallel to the tooth. </li></ul><ul><li>To remove deposits, the cutting edge is applied to the tooth surface and the facial surface of the blade is tilted toward the tooth to achieve a 70-85 ° angle between the tooth and the blade. </li></ul><ul><li>Apply lateral pressure against the tooth and pull upward while maintaining contact with the tooth. </li></ul>Pull Stroke Lateral Pressure 70-85 °
  8. 8. Anterior Universal <ul><li>To scale the facial surfaces, place the toe of the blade toward the proximal surface with the handle parallel to the tooth. </li></ul><ul><li>Apply strokes to remove deposits from the midline of the tooth to the proximal surface. </li></ul><ul><li>Work from canine to canine. </li></ul><ul><li>Switch working ends and repeat for surfaces away from you. </li></ul><ul><li>Repeat all of the above for the lingual surfaces. </li></ul>SBH5/67
  9. 9. Universal Curettes <ul><li>Anterior Universal Instrumentation Sequence </li></ul>
  10. 10. Posterior Universal <ul><li>Begin at the distal line angle of the most posterior tooth. </li></ul><ul><li>Direct the toe of the blade toward the distal with the terminal shank angled slightly toward the tooth. </li></ul><ul><li>Apply strokes from the line angle to the contact area. </li></ul><ul><li>Next, turn the toe toward the mesial to scale the buccal and mesial surfaces. </li></ul><ul><li>Continue this sequence to complete the posterior region. </li></ul><ul><li>Switch ends and repeat from the lingual aspect. </li></ul>

  12. 12. Curettes Area Specific (Gracey) Curettes
  13. 13. Gracey Curettes <ul><li>In the early 1940’s, Dr. Clayton Gracey and Hu-Friedy introduced a set of instruments designed to be used on specific tooth surfaces that improve adaptation and deposit removal. </li></ul><ul><li>The Gracey “area specific” designs have laid the groundwork for the new instruments of today. </li></ul><ul><li>Today, the Gracey Curette family of instruments give clinicians many options for their treatment needs. </li></ul>
  14. 14. Gracey Curettes <ul><li>The Gracey blade design is offset from the terminal shank at 70°. </li></ul><ul><li>This creates one cutting edge which is referred to as the lower edge. </li></ul>Back Face Toe Cutting Edge Lateral Side °
  15. 15. Gracey Instrumentation <ul><li>The blade of a Gracey Curette is correctly adapted when the lower cutting edge is against the tooth and the terminal shank is parallel to the tooth surface being scaled. </li></ul><ul><li>Apply lateral pressure against the tooth (root) and pull upward, maintaining the parallel shank. </li></ul>Pull Stroke Lateral Pressure 70 °
  16. 16. Gracey Curettes <ul><li>The shank design is different for each Gracey pattern. </li></ul>
  17. 17. Gracey Curettes <ul><li>Gracey Curettes are available in: </li></ul><ul><ul><li>Standard </li></ul></ul><ul><ul><li>Rigid </li></ul></ul><ul><ul><li>After Five </li></ul></ul><ul><ul><li>Mini Five </li></ul></ul>The following slides will explain each of these in more detail.
  18. 18. Standard Gracey Curettes <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 a perfect working angulation for the tooth surface. </li></ul><ul><li>Gracey Curettes are used in a set to completely scale the dentition. </li></ul>
  19. 19. Gracey Design Comparisons * The 17/18 is a unique pattern, having a longer terminal shank and slightly shorter blade, so no AF or MF are available. 1/2, 3/4, 5/6, 7/8, 11/12, 15/16, 13/14 Decreased by 10% Decreased by 50% Longer terminal shank, increased diameter Rigid Mini Five SAS#/#R 1/2, 3/4, 5/6, 7/8, 11/12, 15/16, 13/14 Decreased by 10% Decreased by 50% Longer terminal shank, standard diameter Mini Five SAS#/# 1/2, 3/4, 5/6, 7/8, 11/12, 15/16, 13/14 Decreased by 10% Standard Longer terminal shank, increased diameter Rigid After Five SRPG#/#R 1/2, 3/4, 5/6, 7/8, 11/12, 15/16, 13/14 Decreased by 10% Standard Longer terminal shank, standard diameter After Five SRPG#/# 1/2, 3/4, 5/6, 7/8, 9/10, 11/12, 15/16, 13/14, 17/18* Standard Standard Standard design, increased shank diameter Rigid SGR#/#R 1/2, 3/4, 5/6, 7/8, 9/10, 11/12, 15/16, 13/14, 17/18* Standard Standard Standard Standard (Finishing) SG#/# Available Patterns & Areas of Use (Chart on next slide) Blade Width Blade Length Shank Design and Diameter

  21. 21. Standard Gracey Curettes 7/8 11/12 15/16 17/18
  22. 22. Rigid Gracey Curettes <ul><li>All Gracey designs are available with a wider taper – rigid shank. </li></ul><ul><li>The rigid shank may be preferred for heavier calculus removal. </li></ul><ul><li>Although the shank is wider, the blade width is the same as the standard Gracey. </li></ul>Standard Rigid
  23. 23. After Five ® Gracey Curettes <ul><li>Designed for instrumentation in deeper periodontal pockets. </li></ul><ul><li>The terminal shank is elongated 3mm to provide better clearance around crowns, and superior access to root contours and pockets 5mm or more in depth. </li></ul><ul><li>Blade thinned by 10% to ease gingival insertion and reduce tissue distention. </li></ul>3mm
  24. 24. Gracey After Five Curettes <ul><li>The change in the location of the shank bend permits deeper insertion into periodontal pockets. The thinned blade allows for easier insertion. </li></ul>SRPG11/12
  25. 25. Mini Five ® Curettes <ul><li>Designed with the same elongated terminal shank 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 3mm
