Study Notes
Instrument Design
- Working End is the primary area for calculus removal.
- Working End Microanatomy includes a face, lateral surface, cutting edge, toe/tip, middle, and heel.
- CureSe and Sickle instruments have a toe, middle, and heel on the working end.
- Sickle instruments have a rounded back and pointed back and are triangular in cross-section.
Three Basic Parts of a Periodontal Instrument
- Handle is designed for comfortable grip and control.
- Shank connects the handle and working end.
- Working End is designed for specific functions and is the area that comes in contact with teeth.
Shank
- Shank is the link between the working end and the handle. It allows access to teeth in the mouth.
- Shanks are categorized as simple and complex based on their bends and shapes.
- Functional Shank is the portion closest to the working end, extending to the first bend.
- Lower Terminal Shank is the portion closest to the working end, extending to the second bend.
Instrument Design Features
- Design Name identifies the school or designer.
- Design Number provides an exact identification of the instrument.
Variability in Shanks
- Standard and Extended Shank lengths influence instrument access.
- Shank flexibility and rigidity are determined by diameter and thickness.
- Rounded Side of the shank does not cut.
- Cutting Side has edges designed for removing calculus.
Instrument Selection and Use
- Gracey 9/10 instruments are designed for posterior teeth with a large blade.
- Gracey 11/12 and 13/14 instruments are designed for multi-rooted teeth, with long, complex shanks.
- Gracey 11/12 and 13/14 instruments are paired and used together for cleaning different tooth surfaces.
Instrument Maintenance
- Instruments require care and maintenance for effective use.
- Instrument sharpening is important.
- Sharpening stones come in different types and require understanding to use effectively.
