Immediate periodontal bone plate changes induced by rapid maxillary expansion in the early mixed dentition: CT findings

Abstract: ObjectiveThis study aimed at evaluating buccal and lingual bone plate changes caused by rapid maxillary expansion (RME) in the mixed dentition by means of computed tomography (CT).MethodsThe sample comprised spiral CT exams taken from 22 mixed dentition patients from 6 to 9 years of age (mean age of 8.1 years) presenting constricted maxillary arch treated with Haas-type expanders. Patients were submitted to spiral CT scan before expansion and after the screw activation period with a 30-day interval between T1 … Show more

“…The most common RME procedure is performed with tooth-borne or tooth-tissue-borne palatal expanders [9, 10]. Usually, the appliance is anchored to the upper permanent first molars, which may exhibit undesirable side effects including root resorption [11], buccal tipping, gingival recession and bone loss [12]. In order to avoid the abovementioned effects on the permanent supporting teeth, some authors proposed a modified expander anchored to deciduous teeth [13, 14].…”

“…Outra diferença deste desenho de aparelho foi que a força é distribuída por todo o arco de nivelamento, que nesta fase foi o 0.017x0.025 níquel-titânio termoativado. Respeitando o controle de torque aplicado pelo fio de nivelamento presente nesta fase do tratamento ortodôntico, obteve-se movimento de inclinação controlada dentro do osso alveolar (AKIN et al, 2014, BAYSAL et al, 2013, BRUNETTO et al, 2013, GARIB et al, 2014b, GRAVINA et al, 2013, LEE et al, 2015. A justificava de trabalhar com o arco auxiliar de expansão em TMA (mais flexibilidade que o aço, com liberação de força mais gradual e com formabilidade) associado a um arco de nivelamento retangular e termoativado está ligada as informações destes trabalhos citados, tendo o controle de movimentos de inclinação vestibular pelo fio retangular, embora com folga no "slot" dos bráquetes, para permitir acomodação e remodelação durante o movimento (O'DYWER et al, 2016).…”
