title: Clinical comparative study of the effects of two types of mandibular space-regaining devices.
abstract: This study evaluated the results obtained by two space-regaining devices in children with mixed dentition and premature loss of mandibular deciduous molars. There were no statistical differences between the amount of space regained by each device; however, the distalizing screw regained space at a faster rate.
