It emphasizes the importance of early diagnosis during the mixed dentition phase, allowing clinicians to utilize growth potential to guide dentofacial development and reduce future treatment complexity. Preventive approaches focus on maintaining arch integrity and eliminating etiological factors, while interceptive procedures address developing skeletal and dental discrepancies during growth. The role of functional and orthopedic appliances, applied at appropriate growth stages, is highlighted in achieving favorable skeletal and occlusal outcomes. Overall, early orthodontic intervention is presented as an effective and biologically efficient approach to improving long-term functional and aesthetic results.54enPreventive orthodontics; Interceptive orthodontics; Early intervention; Malocclusion; Mixed dentition; Growth modification; Space maintenance; Functional appliances; Crossbite correction; Serial extraction.Medicine::DentistryHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
