Ergonomics in the dental office

Back 12

Ergonomics designs the work area and the task around the human body. Members of the dental team most frequently perform in a seated position and they often use excessive motion and have unbalanced posture. Many dental team members experience MSDS (musculoskeletal disorders)

Early on shot of pain should alert to the work that 1. Imbalance exists 2. If it is ignored serious damage can occur over time.

Front 13

Ergonomics chair side tips

Back 13

Use muscles to remain balanced for ease of movement

Avoid prolonged awkward positions

Do not remain in one position for an extended time

Do not constantly lean forward or to the side

Take breaks

Remain in good physical condition

Avoid repetitive movements

Rearrange items in the operatory for easy use

Front 14

Dental assistant positioning

Back 14

Sit at patients shoulders

Knees even with the edge of the patients headrest

Head in up right position

Back straight and supported with back rest

Thighs parallel to the floor

Elbows kept close to your body

Avoid sitting on the edge of your chair

Keep your eye level about 6 inch above the dentist

Front 15

Posture

Back 15

Affected the ability of RDA to reach, hold, and use equipment. Positioning also influences how long RDA can preform without suffer from effects

Front 16

Operator positioning

Back 16

Head in an upright position

Elbows kept close

Thighs parallel to the floor

Work in neutral position

Reposition patient as necessary

Front 17

Neutral position

Back 17

Ideal way to work.

Sitting up right with your weight evenly distributed. Legs should be separated with your feet flat on the floor or footrest when you are working

Front 18

Reaching movements

Back 18

Keep most/everything you need at a comfortable distance ( not above shoulder level or below the waist) make sure they are in normal horizontal reach

Keep the light at a safe maximum vertical reach

Other supplies should be placed within maximum horizontal reach

Front 19

Repetition and force

Back 19

Increase the risk for cumulative disorders. To prevent this take breaks, alternate difficult procedures with less stressful ones.
