ABSTRACT The early loss of primary teeth can lead to significant orthodontic issues, including space loss and misalignment of permanent teeth. Space regainers are orthodontic devices designed to address these issues by reclaiming lost space in the dental arch. Non-compliant space regainers, which do not rely on patient cooperation, are particularly valuable in pediatric orthodontics where maintaining compliance can be challenging. Non-compliant space regainers include fixed appliances with mechanical components that exert continuous force to regain space. Examples include the open coil spring space regainer, which uses a spring mechanism to apply consistent pressure on the teeth, and the sliding loop regainer, which employs a similar mechanical approach to restore space without requiring active patient involvement. These devices are designed to function effectively regardless of patient compliance, making them ideal for younger patients. Clinical studies have demonstrated the effectiveness of non-compliant space regainers in maintaining or restoring space in the dental arch, reducing the need for more complex orthodontic treatments, and facilitating the proper eruption of permanent teeth. These appliances have been shown to significantly improve dental health outcomes by addressing space discrepancies early and effectively. In conclusion, non-compliant space regainers offer a reliable solution for managing space loss in orthodontics, especially in cases where patient compliance is a concern. Ongoing research is essential to further optimize these devices and explore their long-term benefits in various clinical scenarios1,2,3.
