Analysis of literature about methods of maxillary expansion

INTRODUCTION . There is an analysis of the literature data on existing methods of maxillary expansion in this article. AIM. To analyze the published data about constriction of the upper jaw and treatment methods. MATERIALS AND METHODS . As part of this work, a bibliographic search was conducted in the following electronic databases: eLibrary, PubMed, Web of Science and Google Scholar. The following keywords were used in the search: “narrowing of the upper jaw”, “expansion of the upper jaw”, “crowded position of teeth”, “palatal suture”, “devices for rapid palatal expansion”, “hybrid devices”, “orthodontic devices”. A manual method of searching for information was also applied. The analysis included articles mentioning information about the treatment of patients with constriction of the upper jaw. RESULTS . After reviewing and analyzing the articles, according to the criteria described earlier, several publications were identified that meet the inclusion criteria, among which a number were submitted by foreign authors. CONCLUSIONS . In the process of choosing a treatment method for a patient with a narrowing of the upper jaw, it is necessary to pay attention to the stage of maturation of the palatal suture when planning orthodontic treatment, as well as apply modern methods of maxillary expansion in practice, which have a less traumatic effect on the maxillary jaw. Analysis of literature has shown that the usage of hybrid devices based on miniimplants can reduce the negative effects leading to complications, however, in the course of our work, it was determined that for a more detailed consideration of this type of treatment, it is necessary to analyze a larger number of clinical cases and literature.
