Purpose: The aim of this study was to investigate arch parameters and dentoalveolar changes from pretreatment to posttreatment by comparing the Miniscrew Assisted Rapid Palatal Expansion (MARPE), Periodontally Accelerated Osteogenic Orthodontics (PAOO), and Damon self-ligating bracket therapies.
Materials And Methods: Seventy-nine patients underwent maxillary expansion followed by or in conjunction with Damon ( = 23), PAOO ( = 28), and MARPE ( = 28) therapies. Nine maxillary dental arch parameters were compared at pretreatment, posttreatment as well as, increments of treatment change.
