Patient & Operator Positioning Flashcards
An injury affecting the musculoskeletal, peripheral nervous, and neurovacular systems:
Work-related musculoskeletal disorder
What is the cause of a work-related musculoskeletal disorder?
Caused by prolonged, repetitive, forceful or awkward movements, poor posture, ill-fitting chairs & equipment, or fast-paced workload
The ideal positioning of the body while performing work activities; associated with decreased risk of musculoskeletal injury:
Neutral position
The ideal position of the patient during dental treatment:
Supine position
Position of patient lying on their back in a horizontal position and the chair back nearly parallel to the floor:
Supine position
The science of adjusting the design of tools, equipment, tasks, and environments for safe, comfortable, and effective use:
Ergonomics
What is the most common error dental clinicians can make when positioning themselves and their patients?
Positioning the patients too high during dental procedures
What position is seen in the following image for a RH-clinician:
8 o’clock for RH-clinician
What position is seen in the following image for a RH-clinician:
9 o’clock for RH-clinician
What position is seen in the following image for a RH-clinician:
10-11 o’clock for RH-clinician
For proper seating positions that yield the most advantageous instrumentation what is of utmost importance?
understanding where you sit in regard to what tooth you are scaling
Proper positioning of the clinician and patient leads to better:
leverage/fulcrum/removal of deposits on teeth
Proper seating and positing of the clinician and patients allows for proper:
adaptation of instruments on tooth surfaces (especially in areas of crowding or malpositioned teeth)
in consideration for posterior teeth and proper seating positioning, we divide each sextant into what aspects:
direct & indirect
When you are seated at 9 o’clock, the aspect of teeth you can see directly are where you would:
Stay at 9 o’clock
When you are seated at 9 o’clock, the aspect of teeth you cannot see directly are where you would:
Move to 10 to 11 o’clock
What position would a RH-clinician be at, if these teeth were in view:
(patient is turned slightly away from clinician, chin-DOWN position)
9 o’clock
What position would a RH-clinician be at, if these teeth were in view:
(patient is turned slightly away from clinician, chin-UP position)
9 o’clock
What position would a RH-clinician be at, if these teeth were in direct view:
9 o’clock
Describe what type of vision is used to view these teeth in the 9 o’clock position:
Direct vision
9 o’clock position for posterior segments for a RH-clinicians allows for:
Direct vision
What position would a RH-clinician be at, if these teeth were in view:
(patient turned toward the clinician, chin-UP position)
10-11 o’clock
What position would a RH-clinician be at, if these teeth were in view:
(patient turned toward the clinician, chin-DOWN position)
10-11 o’clock
What position would a RH-clinician be at, if these teeth were in indirect view:
10-11 o’clock
10-11 o’clock position for posterior segments for a RH-clinicians allows for:
indirect vision
With the given treatment area, describe the clock position & patient head position for RH-clinicians:
mandibular arch- anterior surfaces toward
8-9 o’clock
slightly toward, chin-DOWN
With the given treatment area, describe the clock position & patient head position for RH-clinicians:
maxillary arch- anterior surfaces toward
8-9 o’clock
slight toward, chin-UP
With the given treatment area, describe the clock position & patient head position for RH-clinicians:
mandibular arch- anterior surfaces away
12 o’clock
slightly toward, chin-DOWN
With the given treatment area, describe the clock position & patient head position for RH-clinicians:
maxillary arch- anterior surfaces away
12 o’clock
slightly toward, chin-UP

mandibular arch- posterior aspects with indirect vision
10-11 o’clock
toward, chin-DOWN
