The Concepts of Four-handed Dentistry Including Ergonomic Instrument Transfer and Exercises for Stress Reduction
Course Number: 643
To maximize the efficiency of an instrument transfer technique the assistant needs to follow these guidelines:
Maintain instruments on a pre set instrument tray or cassette in the sequence of use to facilitate rapid location of needed instruments during a procedure.
Anticipate the need for the next instrument.
Stay alert, with eyes on the operative field, for any change in the procedure.
Be ready to modify the instruments when necessary.
Place the instrument to be transferred in proper position of hand.
Position the working ends of instruments need for the proper dental arch, up for the maxilla and down for the mandible.
Receive the used instrument from the operator.
Use positive pressure during the transfer of the instrument to ensure the operator senses that the instrument has been delivered; this eliminates the operator from looking away from the site or fumbling the delivered instrument.
Move used instrument back into hand and remove debris from the instrument.
Replace on the tray in the appropriate position or into transfer position if the instrument is to be used again.
