Orthodontic Space Management in Pediatric Dentistry: A Clinical Review

The mixed dentition stage is a vital period characterized by significant physiological changes, including jaw growth, the development and eruption of permanent teeth, the exfoliation of primary teeth, and the maturation of surrounding soft tissues. These processes collectively ensure functional, esthetic, and stable occlusion. Disruptions during this stage, such as the premature loss of deciduous teeth, can lead to spacing or crowding issues and affect the dental arch length and the position of permanent teeth. To prevent or mitigate malocclusion, space maintainers and regainers are commonly used as part of space management strategies during the mixed dentition phase. This clinical review examines traditional and modern approaches to space management, highlighting the types of appliances used and their effectiveness. It emphasizes the importance of preserving primary teeth until their natural exfoliation, as they serve as the best natural space maintainers. In cases of premature tooth loss, removable or fixed space maintainers and regainers are effective tools to minimize malocclusion and ensure optimal dental outcomes.
