  4. Site Specific: 1/2 7/8 11/12 13/14 Types: Regular Rigids Minis After- Fives Gracey Instruments:

  5. Please take a few minutes to read the following: Nield book: Module 16 pp. 333- 355 Darby book: pp. 419- 423 Use the following remaining slides as an adjunct to your reading.

  6. Types: Regular Rigid

  7. Notice that the Gracey instrument: has only one cutting edge already angled at 70 degrees face of instrument always slants towards the tooth

  8. 1/2 7/8 11/12 13/14 Where each instrument is used:

  9. The top row of instruments are instruments found in your cassette:

  10. Sequence: • Determine how many teeth you can complete in the time allotted • ALWAYS start with the most posterior tooth in the quadrant- Distal surface • Begin with the 13/14 and complete distal bucal surface of say- 3 teeth • Then complete the buccal to mesial surfaces with the 11/12 • NOW: with the same sequence (13/13, 11/12) complete lingual surfaces

  11. When you have completed the teeth originally planned, move onto the remaining teeth in that quadrant. • Keep in mind that you must keep an eye on the clock so that all the surfaces of a tooth are completed BEFORE you dismiss your patient. • Sometimes that means you can only complete one tooth in the given time, or you might be able to complete all the teeth in the quadrant. • Consider the following when planning: • Tenacity of the deposit (how difficult to remove?) • Patient management (are they a talker? too sensitive?)
