A systematic review}, year = {2019}, url = "http://tede2.pucrs.br/tede2/handle/tede/8733", abstract = "The main objectives of this study were to evaluate through a systematic review the stability and complications of tooth-borne (TB) and bone-borne (BB)/ Hybrid-borne (HB) appliances in surgically assisted rapid maxillary expansion (SARME), identifying the types of appliances that best optimize SARME procedures and to assess the quality of scientific literature available. The main search was carried out in PubMed, Embase, Cochrane Library and SciELO databases, a grey literature search through Google Scholar and a manual search of the articles included. Forty-seven articles were included in the eligibility process (46 articles of the main search and one article founded in the grey literature, ?=0.854). After the eligibility process (17 articles, ?=0.866) and the manual search (6 articles), 23 were finally included. Stability of TB appliances showed width relapse percentages that ranged in canines from 4-35%, in premolars from 1-37% and in the molars from 0.2-49.5%. For BB appliances, the width relapse percentages ranged in canines from 1.7-21%, in premolars of 1.5% and in molars from 4.6-11.5%. For HB appliances, the width relapse was of 14% for premolars and a gain of 1.8% of gain reported in the molar area. For skeletal measurements, similar relapse percentages were encountered in TB and BB appliances in the nasal floor (11-53% in TB and 41.6% in BB appliances) compared to the relapse percentages in the maxilla level (18% relapse and 10% of width gain in TB appliances and 16% of relapse in BB appliances). The most prevalent complications were bone resorption in TB appliances (18.14%) and in BB appliances were related to the appliance (17.9%). The studies presented high risk of bias in 19 studies, medium in 3 studies and low in one study. The TB and BB appliances in procedures of SARME were considered for having a high stability in the long-term, but the relapse encountered is highly influenced in the post-orthodontic treatments, where arc-form coordination is achieved in the consolidation periods. It seemed to be that BB appliances had lesser relapse than TB appliances, however, there were not encountered significant differences in the relapse percentages when compared both groups in randomized clinical trials. It is necessary to carry out studies with better methodological designs with low risks of bias, in order to have homogeneous variables and bigger samples, therefore meta-analytic studies could be performed and clinical high scientific based decisions made for achieving the best outcomes in SARME.", publisher = {Pontif?cia Universidade Cat?lica do Rio Grande do Sul}, scholl = {Programa de P?s-Gradua??o em Odontologia}, note = {Escola de Ci?ncias da Sa?de} }
