The Begg light wire appliance remains unique in the history of orthodontic innovation. Whereas many current self ligating bracket appliances suppose to be low friction or friction free, it is the Begg appliance that best exemplifies low friction, free sliding mechanics, by creating only a single point of contact between the bracket and the arch wire.
One key advantage of the appliance set up was the use of light elastic forces for the correction of anterior overbites and overjets. This mechanism sets up differential intra oral anchorage and a system of preferential tooth movement where certain teeth or blocks of teeth regulate independently. This system need Monthly visit and it is a cheaper treatment method of orthodontics.
