Long-Term Effects of Three Different Appliances for Rapid Maxillary Expansion: A Systematic Review and Meta-Analysis.

ABSTRACT:

Objective

To compare the long-term effects (≥6 months) of bone-borne (BB) and tooth-BB appliances with tooth-borne (TB) appliances in rapid maxillary expansion.

Materials and methods

An electronic search was conducted in PubMed, Cochrane Library, Scopus, Embase, Web of Science, Proquest, ClinicalTrials.gov, and OpenGrey. The Grading of Recommendations, Assessment, Development, and Evaluation approach was used to evaluate evidence. Mean differences were calculated, applying a random effects model.

Results

Nine studies were included. Six articles were randomized controlled trials (RCTs), two were retrospective studies, and one was a parallel cohort study. Three non-RCTs were at moderate risk of bias. Three RCTs were at unclear risk of bias, while three were at high risk
