Sometimes molars are distalized to make space for other impacted teeth, such as premolars or canines, in the mouth.
The study did have some limitations such as different type of appliances used in different papers and different landmarks used in the evaluation of cephalometric radiograph.
A careful approach must be undertaken in patients with severe space discrepancy and hyperdivergent growth pattern for the procedure of molar distalization.
Norman William Kingsley was the first person to try to move the maxillary teeth backwards in 1892 by means of headgear.
Albin Oppenheim later advocated for the use of occipital anchorage to move the maxillary teeth backwards.
