Age, Sex, and Maxillary Position Are Associated with Successful Microimplant-Assisted Rapid Palatal Expansion in Adults

The purpose of this study was to investigate the possible predictors success microimplant-assisted rapid palatal expansion (MARPE) in skeletally mature patients. Additionally, factors associated with amount maxillary were analyzed. Factors MARPE analyzed 53 adult patients (27 males, 26 females, mean age 25.8 ± 8.9 years, and range 18.0 56.6 years) who had a transverse deficiency greater than 2 mm cervical vertebral maturation stage 6. Age at pretreatment (T1), sex, sutural bone density T1, type appliance, mode microimplant fixation, lateral cephalometric variables T1 considered for inclusion as success. In showed successful skeletal expansion, linear distances widths measured on cone-beam-computed-tomography images after (T2), total, 41 expansion. (p = 0.019), sex 0.002), A-N perp 0.015) significantly MARPE. SN-MP midpalatal-suture T1. conclusion, there is chance failure male are older have retrusion. A can be expected higher mandibular-plane angle lower density.
