Microscrew-assisted rapid palatal expansion (MARPE) tech-nique. Potential causes of treatment failure and adverse effects: Scoping review.

A non-surgical orthodontic treatment strategy for transverse maxillary deficiencies, espe-cially in late adolescents and young adults, is microscrew-assisted rapid palatal expan-sion (MARPE). The literature indicates several concerns regarding its long-term efficacy and potential complications. Recent studies have provided valuable insights into the technique of MARPE, particularly focusing on its efficacy, potential complications, and treatment failures. The present scoping review is a summary of the most relevant literature published in the last decade regarding MARPE, emphasizing the disadvantages, causes of treatment failure, and potential local and systemic adverse effects.
