Which is the use of Gracey curette 11 12?
Gracey 11/12 is area specific curette used for subgingival debridement of mesial surfaces of upper and lower premolars and molars. After identification of the cutting edge, curette is inserted into the pocket and vertical strokes are used for calculus removal.
What is the Gracey 13 14 used for?
Gracey curettes are area specific instruments, designed for all types of calculus removal and root planing. With a rounded toe and only one cutting edge, Graceys have a “safe-side” for carefree deep periodontal cleaning. LM’s optimally contoured blade tips follow curved tooth morphology.
What is the Gracey 15 16 used for?
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. It is used on the mesial surfaces of the posterior teeth but has the shank design of a Gracey 13/14 (Figures 11‑12).
Which Gracey curette is most appropriate?
A Gracey 7/8 is arguably the most versatile in the range and can be used on the buccal and lingual surfaces of bicuspids and molars. The instrument has a large contra-angle with only a medium return angle and a shorter shank than the previous described curettes.
What is a Gracey 11 12?
Designed to adapt to mesial surfaces of posterior teeth for sub-gingival scaling and root planing. The XP blade is 15% thinner than stainless steel instruments and blade angle allows for easier insertion into the sulcus while minimizing soft tissue trauma.
What does a Gracey curette look like?
Similar to the universal curette, the Gracey curette features a rounded back and toe with a semicircular cross section, which prevents damaging the gingival tissue.
What is an after 5 Gracey curette?
The After Five Gracey features a terminal shank 3 mm longer than a standard Gracey curette, and a thinner blade for improved access. Gracey curettes are designed to adapt to a specific area or tooth surface. Features and Benefits. Blade thinned by 10% to ease gingival insertion and reduce tissue distention.
What is the difference between a scalar and a curette?
The major difference between the design of a scaler and a curette is in the shape of the blade. In cross section, the blade of a scaler is triangular, whereas a curette is semicircular. Area-specific curettes, such as the Gracey curettes, are designed so that each blade adapts to a specific tooth surface or area.
Where do I use Gracey curette?
Along with universal curettes, Gracey curettes are one of the main instruments used for scaling and root planing. Gracey curettes are especially ideal for subgingival calculus removal because the design of the instrument allows for better adaptation to the anatomy of the roots.
What are the dimensions of a Gracey 17 / 18?
The extra angulation allows better adaptation and a more stable intraoral fulcrum. The Gracey 17/18 is a modified 13/14 with a 3 mm elongation of the termination shank and a 1 mm shorter blade to provide better access and adaptation to posterior distal surfaces. 4
What kind of instruments are in the Gracey series?
The original Gracey series has seen many evolutions, including rigid and extended shanks, mini working ends, and markings on the shank.
How is the Gracey Curet used in submarginal instrumentation?
This tilt or offset allows the lower cutting edge of the area-specific curet to be at the correct angulation when the lower shank is parallel to the instrumented tooth surface. 1 This angulation and the curved toe and back of the Gracey curet allow submarginal instrumentation without tissue trauma.
What was the original purpose of the Gracey Curet?
Gracey curets were originally designed with a flexible shank to improve tactile sensitivity and to remove light calculus; these are often called finishing curets. 4 Graceys are also manufactured with a rigid shank for moderate to heavy calculus removal. Recent additions to the original 14 working ends are the Gracey 15/16 and 17/18.
