Maxillary changes with bone-borne surgically assisted rapid palatal expansion: A prospective study.
INTRODUCTION The aim of this prospective study was to analyze the postexpansion positional changes of the maxillary halves and their initial stability after transpalatal distraction with a bone-borne distractor and standard corticotomies of the anterior, lateral, and median bony supports of the maxilla without pterygomaxillary disjunction. METHODS The sample consisted of 21 patients (15 femal...

متن کاملSkeletal and dental changes following surgically assisted rapid palatal expansion.
The purpose of this study was to analyse the changes produced by surgically assisted rapid palatal expansion (SARPE) longitudinally on 14 patients aged between 18 and 41 years. A pre-fabricated Hyrax appliance was cemented prior to the surgical intervention, which consisted of a maxillary buccal corticotomy with pterygoid separation. Models and postero-anterior (PA) headfilms were taken before ...
متن کاملSurgically assisted rapid palatal expansion: orthodontic preparation for clinical success.
Close root proximity between the maxillary central incisors presents a problem in the surgical management of a maxillary palatal expansion. During the surgical fracture of this interdental area, the possibility exists for a separation to occur between the root surface and the bone. If this does occur, it is paramount that the gingival attachment remain intact. Asymmetric separation places more ...
