Non-surgical rapid maxillary expansion with mini-implants in adults: A Narrative Review

Abstract

Introduction: In recent years, rapid maxillary expansion (RME) in prepubertal growth stages has been deeply investigated; however, its study has recently been increasing in adults without need for surgery. The objective of this review is to present the results reported in the scientific literature about RME in adults. Material and Methods: Six databases were used to carry out the secondary search of the review. The search was performed virtually and studies from the last six years were considered, with a last search performed until November, 2022. Results: A total of 253 studies were found, from which 20 studies were finally selected. RME in adults can result in substantial expansion similar to that obtained in patients who have not yet completed the ossification of the mid-palatal suture. Conclusion: The reviewed scientific literature shows evidence that there are various devices supported by mini-implants as non-surgical treatment options to correct transverse deficiency and help expand the maxilla in adult patients.
