Since miniscrew implants provide absolute anchorage, they can be used to
support distalizing devices, consequently reducing the unwanted incisor proclination
and the mesial movement of premolars. Recently, several conventional distalizing
devices have been adapted to allow their connection with miniscrew implants, thus
providing anchorage reinforcement.

Such combination generates a new class of
devices, so-called miniscrew supported devices.
Although several studies have been published describing the overall dental
changes produced by intraoral distalizing devices, comparisons of the dental effects
produced by both conventional distalizing devices and miniscrew supported devices
have not been performed.
Therefore, the purpose of this systematic review was to compare the overall
dental effects (amount of molar movement, the degree of molar distal tipping and the
rate of molar movement) and distalizing force magnitude between conventional
distalizing devices and miniscrew supported devices.
