Quick Reference

The position of the operator when undertaking restorative dentistry in a seated position that is most ergonomic and provides the least muscular stress. A balanced posture is characterized by the upper arms being vertical and in contact with the rib cage, the forearms parallel to the floor, the body weight evenly balanced, and the seat height such that the heels rest comfortably on the floor.
