  1. Chapter 9 CLINICAL DENTISTRY

  2. Instrument Transfer • Smooth efficient transfer of instruments and dental materials is a team effort, requires communication, coordination, and practice between the dentist and you • Transfer happens in the Transfer Zone • Clinical Assistant must understand the sequence of the procedure, be able to anticipate when a new instrument is required • Minimum motion should be used when transferring instruments(use only finger, wrist and elbow) • Instruments transferred in the position of use (working end of the instrument is directed toward the tooth you are working on • Instrument must be transferred so that the dentist can grasp the handle properly • Dentist must have a firm hold on the instrument

  3. Clinical Assistant’s Transfer Technique • Single-Handed Technique- used for efficiency, applies to hand instruments, dental handpieces, air-water syringe • An Instrument is retrieved from the tray set-up using thumb, index finger, and middle finger of the left hand (Fig. 9-8, pg. 138) • The used instrument is retrieved at the end of the handle, or opposite end of the working end using the last two fingers of the left hand (fig.9-9, pg. 139) • The New instrument is transferred in the transfer zone and positioned firmly into the operators grasps (fig. 9-10, pg. 139) • Direct the working end of the instrument toward the tooth surface or arch that the operator is working on • Operator’s Grasp- the manner which the dentist holds an instrument, see Fig. 9-11, pg. 139

  4. Variations of Instrument Exchange • Mirror and Explorer- at the beginning of the procedure the dentist will use the mirror and explorer to inspect the area of the mouth (Fig. 9-12, pg. 140) always deliver them together using the two handed exchange • Hinged Instruments- forceps, scissors, pliers are held at the hinge of the instrument and transferred by directing the handle of the instrument into the dentist’s palm or handle of scissors into the fingers of the dentist, (fig. 9-13, pg. 140) • Cotton Pliers- are used to transfer small items, deliver them while they are pinched together, prevents dropping them items being held, (fig. 9-14, pg. 140) • Transfer of Dental Materials- delivered in the transfer zone, cements and liners are delivered on the slab and along with the applicator instrument. Materials in syringes are passed with the syringe portion towards the dentist so that he can extrude materials out, tips on syringes should be pointed up for maxillary and down for mandible areas • Amalgam- carrier should be filled and pointed up for the maxillary and down for the mandible
