Abstract
PEREZ-FLORES, A. et al. Risks associated with the use of Maxillary Rapid Expansion. Av Odontoestomatol [online]. 2020, vol.36, n.1, pp.21-26. Epub Dec 05, 2022. ISSN 2340-3152. https://dx.doi.org/10.4321/s0213-12852020000100003.
Introduction:
The dentomaxillary anomalies correspond to a group of alterations that hinder the harmonic development of the jaws, where we find the transversal anomalies. Rapid Maxillary Expansion (RME) is used as a treatment for transverse anomalies, its objective is to increase the transversal distance by separating both hemiarchies at the level of the palatal suture, using a fixed and rigid expander. The most used are the Hass, Hyrax and McNamara expanders.
Objective:
The objective of this review is to identify the EMR risks reported in the literature related to Hass, Hyrax and Mc Namara expander.
Methodology:
A search was made in PubMed, Scielo, Science Direct, Trip Database and Google Scholar using the terms: “Rapid Maxillary Expansion”, “Risks”, “Child”, “Maxillary Expansion”, “RME”, “Palatal Expansion”, “Hyrax”, “Hass”. Studies in English and Spanish were included, without limits in the year of publication or type of study. As exclusion criteria, we consider surgical expansion, slow expansion or other simultaneous treatment during the active expansion phase.
Results:
Of the articles found, twenty met the inclusion criteria. Among the risks are: accidental swallowing of the expander activation device, transient bacteremia, deviation of the nasal septum, root resorption, periodontal involvement, positional change of the condyles, soft tissue facial changes and skeletal changes.
Conclusion:
RME is an effective orthopedic procedure, its indications in early treatment have increased due to positive results. According to the bibliography found, the benefits considerably outweigh the negative effects.
