Instrument Transfer
- 1.
- 2. Instrument Transfer Proper instrumenttransfer occurs when: Operator’s view remains on oral cavity Stress and fatigue are reduced Safety and comfort are maintained Production is increased with less motion
- 3. Instrument Transfer Efficient transferallows the operator to keep his or her eyes focused on the oral cavity and requires minimal movement of the operator’s hands. A smooth transition occurs when the assistant is able to anticipate the operator’s needs.
- 4. Instrument Transfer Transferzone Area just below patient’s nose near chin Fulcrum Point of rest on which fingers are stabilized and can pivot Tactile sensation Feeling sensed by touch
- 5. Instrument Transfer Transfer hand Assistantpasses and receives instruments with left hand while working with right-handed dentist Assistant passes and receives instruments with right hand while working with left-handed dentist
- 6. Instrument Grasps The wayan instrument is held influences how efficiently the instrument can be used. Selecting the correct grasp allows the operator control of the instrument, greater tactile sensitivity, and reduces fatigue to the operator’s fingers and hands.
- 7. Instrument Grasps Pen Grasp The pen grasp is held between the pad of the thumb and the pad of the index finger with the side of the middle finger on the opposite side of the thumb, as a pen is held. Used to hold instruments that have angled shanks
- 8. Instrument Grasps Pen Grasp The modified pen grasp is similar to the pen grasp, but the middle finger is placed on top of the instrument with the index finger. Preferred by some operators and provides more control and strength in some procedures. Lessens operator fatigue Used with instruments that have angle shanks, like pen grasp.
- 9. Instrument Grasps Pen Modified pen • The pen grasp is held between the pad of the thumb and the pad of the index finger with the side of the middle finger on the opposite side of the thumb, as a pen is held. • The modified pen grasp is similar to the pen grasp, but the middle finger is placed on top of the instrument with the index finger.
- 10. Instrument Grasps Palm Grasp The operator holds the instrument in the palm of the hand and the fingers grasp the handle of the instrument in the palm grasp. Used with surgical pliers, rubber dam forceps and other forceps. Usually, palm up when working on Maxilla and palm down when working on Mandible.
- 11. Instrument Grasps Palm-thumb grasp In the palm-thumb grasp, the operator grasps the handle of the instrument in the palm while the thumb is extended upward from the palm. Used with instruments having straight shanks and blades such as the straight chisel or the Wedelstaedt chisel
- 12. Instrument Grasps Palm Palm-thumb • The operator holds the instrument in the palm of the hand and the fingers grasp the handle of the instrument in the palm grasp. • In the palm-thumb grasp, the operator grasps the handle of the instrument in the palm while the thumb is extended upward from the palm.
- 13. Instrument Grasps Reversepalm-thumb a variation of the palm-thumb grasp, which is used to hold the evacuator tip in the mouth of the patient. Failure to master these basic skills may result in injury to the patient, dentist, or the assistant and/or loss of production for the office.
- 14. Eight Basic Rules Theassistant selects the next instrument and holds it until the dentist signals for transfer. There are eight basic rules for instrument transfer.
- 15. Eight Basic InstrumentTransfer Methods 1. Primary working end should be placed away from assistant on tray 2. With straight-shank instruments, primary working end should be placed toward assistant
- 16. Eight Basic InstrumentTransfer Methods 3. With hinged instruments, beaks are placed toward assistant 4. Hold instrument between thumb and index finger and middle finger
- 17. Eight Basic InstrumentTransfer Methods 5. With pen grasp instrument, pick up instrument from tray near end closest to assistant 6. Assistant’s hand is placed on instrument opposite from end operator uses
- 18. Eight Basic InstrumentTransfer Methods 7. Rotate working end of instrument until it is directed toward dental arch being treated 8. Hold instrument to be passed parallel to instrument held by operator
- 19. Correctly holding, readyfor transfer
- 20. Instrument Transfer Methods Instrumentstransferred by: One-handed transfer Two-handed transfer
- 21. One-Handed Transfer The one-handedtransfer is the most common transfer. It saves time and allows the assistant to use the evacuator or air-water syringe at the same time. The assistant picks up the instrument to be transferred with the same hand that receives the instrument the operator is finished using.
- 22. Two-handed Transfer Withthe two-handed transfer, the assistant uses both hands for transfer. One hand receives the instrument from the operator, and the other hand passes the next instrument.
- 23. Instrument Transfer Modifications Mirror and explorer transfer Transfer of instruments must be modified when the size or weight of an instrument does not allow normal transfer. The mirror and explorer transfer is performed at the beginning of treatment. The assistant picks up the mirror in the right hand and the explorer in the left hand and passes them to the dentist when signaled.
- 24. Instrument Transfer Modifications Cottonpliers transfer Accomplished when non-locking cotton pliers are used to transfer small items.
- 25. Instrument Transfer Modifications Scissorstransfer transferred as the assistant picks up the scissors at the hinge near the working end with them slightly opened.
- 26. Instrument Transfer Modifications Dentalhandpieces Bulky and can be transferred with the one-handed transfer as the assistant picks them up near the hose attachment, away from the working end. © Cengage Learning 2013
- 27. Instrument Transfer Modifications Air-watersyringe transfer Transferred as the assistant holds the end of the syringe, covering the nozzle and tip with the palm of the hand.
