ABSTRACT
The use of aligners in the treatment of children during the mixed dentition period, when the dental and jaw system is still in a stage of active growth and development, represents a proactive approach to addressing orthodontic issues before they worsen. Despite the advantages, the accuracy of tooth movement with aligners remains a concern, especially for complex movements.
The aim of the study. To evaluate the results of orthodontic treatment during the mixed dentition period using an aligner system with additional elements.
Objects and methods. A clinical examination, anthropometry, and CBCT analysis were conducted for a patient diagnosed with a distal crossbite, and a treatment plan was developed. An aligner system with additional components in the form of elastic cross-elastics was used.
Results and discussion. The importance of considering natural jaw growth, eruption of permanent teeth, and the use of additional components in treatment planning is emphasized. The role of parents in the treatment process and the necessity for regular monitoring of the patient’s condition are also highlighted.
Conclusion.  The use of aligners in pediatric orthodontics is an effective method for correcting malocclusion but requires an individualized approach and careful planning to account for the growth and development characteristics of the dental and jaw system. For expanding the maxilla in the area of the first permanent molars during treatment in the mixed dentition period, the application of cross-elastics is recommended, which will accelerate treatment and create controlled expansion of the upper dental arch through torque correction.
