    15 16 And 17 18 Gracey Fohf 15 16 And 17 18 Gracey Fohf Presentation Transcript

    • 15/16 & 17/18 Gracey Curettes
    • 15/16 & 17/18 Gracey Curettes
      • In this tutorial you will learn:
        • Gracey Curettes overview
        • What 15/16 and 17/18 Gracey Curettes are
        • Features and benefits of 15/16 and 17/18 Gracey Curettes
        • Illustrated uses of 15/16 and 17/18 Gracey Curettes
    • Introduction
      • Gracey Curettes are area-specific to allow for deep scaling, root planing and periodontal debridement.
      • The offset blade provides perfect working angulation for the tooth surface.
        • Only the lower cutting edge of each blade is used.
    • Gracey Blade Design
      • Here is an illustration showing how the Gracey blade design is offset from the shank at 70°.
      • This creates one cutting edge which is referred to as the lower edge.
    • Rigid Gracey Curettes
      • Thicker, stronger, and less flexible shank.
      • The rigid shank is preferred for heavier calculus removal.
      • Although the shank is wider, the blade width is the same as a standard Gracey.
      Standard Rigid
    • After Five Gracey Curettes
      • Designed for instrumentation in deeper periodontal pockets.
      • Elongated terminal shank (3mm).
      • Blade thinned by 10% to ease gingival insertions and reduce tissue distention.
      • Provides increased crown clearance.
      3mm
    • Mini Five Gracey Curettes
      • Designed with the same elongated terminal shank (3mm) and thinned blades as the After Five Gracey Curettes.
      • 50% shorter blade for access to smaller roots, narrow pockets, furcations, and developmental grooves.
      Standard After Five Mini Five
    • 15/16 & 17/18 Gracey Curettes
      • In this tutorial, we will focus on the newest Graceys:
        • Gracey 15/16 Mesial
        • Gracey 17/18 Distal
      • These curettes provide the perfect complementary pair of instruments to scale difficult to reach posterior teeth.
    • 15/16 Gracey Curette
      • The 15/16 Gracey Curette was introduced in 1993.
      • It is designed for increased access to molars, where it can be difficult to position the 11/12 Gracey Curette correctly.
      • Mesial posterior use
      • Shank bends similar to 13/14 Gracey, but with the blade offset to scale mesial surfaces of posterior teeth.
    • Comparison of Graceys
      • 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.

    • 15/16 Gracey Curette
      • 11/12 Gracey Curette – Mandibular First Molar
        • It is often difficult to correctly position the shank parallel to the mesial surface using an 11/12 Gracey Curette. Notice the handle position.
      • 15/16 Gracey Curette – Mandibular First Molar
        • The increased angle of the 15/16 Gracey Curette facilitates correct positioning (resulting in an improved scaling angle) in posterior areas .

    • 15/16 Gracey Curette
      • 11/12 Gracey Curette – Maxillary Molar - Extraoral Fulcrum
        • 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.
      • 15/16 Gracey Curette – Maxillary Molar - Intraoral Fulcrum
        • The increased angle of the 15/16 provides superior adaptation in this area, and allows the choice of an intraoral fulcrum position.

    • 17/18 Gracey Curette
      • The 17/18 Gracey Curette is designed to improve access to the distal surfaces of posterior teeth.
      • Accentuated angles and long terminal shank allows for placement into deep periodontal.
      • The multiple bends improve the handle positioning so interference from the opposing arch is significantly reduced.
      • Reduced blade length enhances adaptation of the entire blade to the tooth.
    • Comparison of Graceys
      • The accentuated angles on the 17/18 (far right) are its most distinguishing feature.
      • These angles improve crown clearance and handle positioning so that access to the distal surfaces of second and third molars is greatly increased.
      13/14 13/14AF 17/18
    • 17/18 Gracey Curette
      • The terminal shank is almost as long as an After Five Gracey, which increases access in periodontal pockets.
      • The blade is 1mm shorter than standard Gracey blades which enables adaptation of more of the blade to the tooth.

    • 17/18 Gracey Curette
      • 13/14 Gracey Curette
        • 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.
      • 17/18 Gracey Curette
        • 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.

      • 17/18 Gracey Curette on Mandible (Skull)
        • Access is improved through the multiple exaggerated bends of the 17/18.

      • 17/18 Gracey and 17/18 Rigid Gracey Curettes
        • The 17/18 is available in Standard (on left) and Rigid (on right) designs.
        • The rigid shank is thicker, providing additional strength for heavy calculus removal.

      • Comparison of Gracey 17/18, 15/16 and After Five 15/16
        • The 17/18 Gracey (right) is the ideal companion to the 15/16 Gracey (left) or the 15/16 After Five (center).
        • These instruments improve access to the most difficult to reach posterior teeth.
