Module 2—Clinician Position in Relation to the

Treatment Area

Section 1Clock Positions for Instrumentation

Clinician Position

During instrumentation the clinician moves around the patient to maintain a neutral body position.Use the face of an analog clock as a guide to identify the clinician’s position in relation to the patient’s head.

Clock Positions

Using an analog clock face as a guide: The patient’s head is at 12 o’clock. The patient’s feet are at 6 o’clock.

Range of Positions

Instrumentation of the various treatment areas may be accomplished from a range of clinician positions in relation to the patient’s head.

-Right-handed clinicians sit from 8 to 1 o’clock

-Left-handed clinicians sit from 11 to 4 o’clock

Patient Head Position

The patient’s head position should facilitate neutral arm, wrist, and hand position for the clinician.

Right-Handed Clinician

Clock Positions

8:00—To the Front of the Patient

9:00—To the Side of the Patient

10–11:00—Corner of Headrest

12:00—Behind the Patient

Left-Handed Clinician

Clock Positions

3–4:00—To the Front of the Patient

3:00—To the Side of the Patient

12:00—Behind the Patient

Summary: Clock Positions

During instrumentation the clinician sits in a range of positions in relation to the patient’s head.These positions are named in reference to the hands on an analog clock face.

Section 2Positioning for the RIGHT-Handed Clinician

Positioning for Anterior Sextants

Recommended Clock Position

-Reduces musculoskeletal stress because the clinician can maintain neutral positioning-Provides optimal vision of the tooth surfaces during instrumentation

Divide Tooth at Midline

Halves of an Anterior Tooth

Surface TOWARD the clinician

Surface AWAY FROM the clinician

Right-Handed Clinician

Anterior Sextants

Anterior surfaces toward right-handed clinician are shaded in yellow

Clock position for clinician ranges from 8 to 9 o’clock

Anterior surfaces away from right-handed clinician are shaded in purple

Skill Building

When practicing positioning, use this reminder sequence:“Me, My Patient, My Light, My Nondominant Hand, My Dominant Hand”

Left-Handed Clinician

Anterior Sextants

Anterior surfaces toward left-handed clinician are shaded in yellow

Anterior surfaces away from left-handed clinician are shaded in purple

Summary-For periodontal instrumentation of anterior teeth, each tooth is divided in half at the midline

-Correct positioning of the seated clinician in relation to the treatment area facilitates neutral position and provides optimal vision
