Thesis (M.Sc.D.)--Boston University School of Graduate Dentistry, 1974. Orthodontics. / Bibliography included. / Unilateral distalization of posterior teeth at times plays a significant role in orthodontic therapy. One example of a factor leading to the need for a unilateral distalizing force is a prematurely lost deciduous molar which allows mesial permanent molar migration. / Many biomechanical approaches have been utilized for molar distalization. For instance, several types of extra-oral appliances have been proposed for unilateral molar movement. While some authors suggest that a removable appliance such as the ACCO is the most efficient, (5,6,7), others contend that a modification of the standard Kloehn extra-oral assembly will resolve the problem quite adequately (13, 21,36,40). / Most studies are directed at either a mathematical, mechanical or typodont analysis of the cervical face bow assembly. (8,13,20,21,36,40) Articles covering the ACCO removable appliance mainly outline its construction, indications, and use. (5,6,7) This study was therefore designed to examine and quantitate the actions of the modified cervical traction gear and the ACCO appliance for unilateral molar distalization on a clinical level.
