INTRODUCTION
Every second child and every third adult requires orthodontic care. However, the greater the extent of necessary dental intervention, the higher the risk of adverse outcomes (clinical, radiological, aesthetic, and others) ranging from 15% to 86% in probability. This systematic review analyzes the most common complications arising from maxillary expansion during orthodontic treatment. These complications result from both errors in treatment strategy and patients’ noncompliance with postoperative recommendations, among other causes.
OBJECTIVE
The aim of this study is to analyze documented cases of complications associated with orthodontic maxillary expansion in patients who received such treatment between 2019 and 2025, and to discuss the relevance of these findings in light of the increasing demand for orthodontic care and the consequent rise in the risk of treatment-related complications.
The article is formatted and structured according to the standards for objective and transparent systematic reviews (PRISMA 2020 revision). Literature sources were obtained from official scientific electronic databases (PubMed, eLibrary.ru, CyberLeninka, The Cochrane Library). The studies included in this review met the eligibility criteria and underwent quality assessment using the Cochrane Risk of Bias tool.
RESULTS
A total of 38 sources describing complications following orthodontic maxillary expansion were selected for analysis. According to these sources, possible complications include root resorption, buccal tipping of teeth, vascular and nerve damage, as well as facial asymmetry with impaired respiration.
CONCLUSION
Orthodontic treatment of maxillary anomalies is a highly effective method of correction; however, potential adverse outcomes must not be overlooked, as the risk of their development depends on both the clinician and the patient.
