Operator seating charts

Clock positions are used to provide clinician with proper visibility and access to various treatment areas in the oral cavity. Operator seating charts are based on the clock positions. Right- and left-handed operators use different customised operator seating charts. The recommended seating charts will enable the operators to achieve neutral body position, control instrument strokes and to avoid work-related musculoskeletal disorder (WMD) during instrumentation.
