Primary teeth play a crucial role in preserving space for the proper eruption of permanent teeth. Premature loss of primary teeth can lead to the migration of adjacent teeth, resulting in crowding, occlusal malocclusion, and impaction of permanent teeth. Space maintainers are utilized to prevent these complications, In recent years, advancements in digital technologies, including CAD/CAM systems and 3D printing, have enabled the development of customized space maintainers with precision and faster production. Bad oral habits typically emerge during infancy and often resolve spontaneously over time. However, the prolonged persistence of certain habits can lead to structural alterations in the teeth and jaw. Early identification and intervention of these habits play a crucial role in preventing future orthodontic problems and promoting the maintenance of a healthy oral structure. Anterior crossbite is a type of malocclusion characterized by the positioning of the upper anterior teeth more lingually to the lower anterior teeth. This condition can lead to aesthetic concerns and negatively impact the psychosocial development of children. Early interventions help prevent the occurrence of more complex orthodontic issues in later years. This review discusses current treatment methods for a multidisciplinary approach, addressing both pedodontics and orthodontics.
