In Begg's technique, anchorage control relies on tipping and uprighting movements rather than bodily tooth movement. The initial stages focus on controlled tipping to create space and move teeth efficiently with minimal anchorage loss. Uprighting springs are subsequently used to correct angulation and enhance anchorage by counteracting unwanted tooth movement. This method allows for effective use of anchorage by manipulating tooth angulation rather than moving the whole tooth bodily, which requires more force and can compromise anchorage. Thus, tipping and uprighting are fundamental to controlling anchorage in the Begg technique.
