Abstract Purpose: The aim of this study is to compare the outcome measures of skeletal and dental expansion with Bone-Borne (BB) versus Tooth-Borne (TB) appliances following SARPE. This study is being done to provide quantitative measurements that will help the oral surgeon and orthodontist in selecting the appliance with, on average, the greatest amount of skeletal expansion and the least amount of dental expansion. Methods: A computerized database search was performed using PubMed, EBSCO, Cochrane, Scopus, Web of Science, and Google Scholar on publications in reputable oral surgery and orthodontic journals. A systematic review and meta-analysis was then completed with the predictor variables of expansion appliance (TB versus BB) and outcome measure of expansion (in millimeters). Results:A total of 487 articles were retrieved from the six databases. 5 articles were included, 4 with CBCT data and 1 with non-CBCT 3D cast data. There was a significant difference in the skeletal expansion (SMD = 0.92, 95% CI [0.54, 1.30], p = Conclusion: The literature points to the fact that in order to achieve more effective skeletal expansion and minimize dental expansion after SARPE, a Bone-Borne (BB) appliance should be favored. Keywords: Bone Borne; Tooth Borne; Rapid Palatal Expansion; SARME; SARPE; Surgically Assisted Rapid Palatal Expansion; Surgically Assisted Rapid Maxillary Expansion.
