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.

Lower-Molar Distalization with Mini-Implant Anchorage in Asymmetrical Class II Cases
Volume 51 : Number 2 : Page 0 : Feb 2017
About half of all Class II malocclusions are asymmetrical. If the upper molar is mesially displaced, the maxillary midline will deviate toward the Class I side, and treatment will require either extraction of one upper premolar or distal molar movement on the Class II side. In 61% of asymmetrical Class II cases, however, where the lower molar is distally displaced, the maxillary midline will match the medium sagittal plane, but the mandibular midline will deviate toward the Class II side. If the profile is convex, asymmetrical extractions (two upper premolars and one lower premolar on the Class I side) are generally used for correction. Another option is to extract four premolars, but this will extend treatment time.
