Space Regaining with Modified Palatal Anchorage Plates
Volume 49 : Number 9 : Page 0 : Sep 2015
Space regaining is an important treatment modality for eruption guidance. Shalish and colleagues reported that space regaining and the removal of obstructions can facilitate spontaneous eruption of impacted premolars. Although several devices have been developed to regain space through molar distalization, these methods may result in anchorage loss, incisor proclination, and a slight increase in vertical facial dimension. Koutzoglou and Kostaki reported a relationship between rapid palatal expansion and the natural eruption of impacted canines, but maxillary expansion has also been related to a loss of height and thickness of buccal alveolar bone at the anchorage teeth.
