Clear Aligners In Mixed Dentition: A Review

Abstract

Following caries and periodontal diseases, malocclusion ranks as the third most prevalent dental issue globally. In children and young adults, it emerges as the second most common dental condition, affecting approximately 30%-40% of this demographic and compromising both appearance and the functionality of the dentofacial apparatus. Malocclusion leads to various negative consequences, such as periodontal diseases, difficulties in chewing, speaking, and swallowing, an elevated risk of injury, and diminished aesthetic appeal. Research indicates that individuals with attractive smiles and proper occlusion experience greater confidence and enhanced health-related quality of life compared to those with malocclusion. This impact extends to children, as poor aesthetics can significantly influence their psychological well-being. When considering methods to correct malocclusion, braces and metallic wires often come to mind, highlighting the importance of addressing aesthetic concerns, especially in younger patients.Before the introduction of braces fixed to the labial surfaces, more primitive methods were employed for correcting malocclusion. However, patients are increasingly concerned with their appearance during orthodontic treatment, making both adults and children reluctant to wear conventional metallic braces. In response to this aesthetic demand, researchers have developed various alternatives to traditional braces, such as composite brackets, ceramic braces, and lingual orthodontics, each with its own set of drawbacks. A contemporary solution for non-extraction cases is the use of clear aligners, specifically designed to address issues such as misaligned teeth, mild crowding, deep overbites, spacing concerns, and narrow arches. One of the most recognized brands in this category is Invisalign, a thin, transparent plastic aligner that facilitates effective tooth movement into the desired position.
