Introduction: This case report highlights the application of an open coil spring space regainer (OCSR) in a pediatric patient with space deficiency during mixed dentition. The use of OCSR in managing space issues is not extensively documented, making this case significant in demonstrating its effectiveness and contributing to the understanding of fixed space regainers in pediatric orthodontics.

Clinical findings: An eight-year-old boy presented with multiple missing teeth in the lower right and left posterior regions. Clinical examination revealed space loss in the lower left premolar region due to adjacent tooth migration. Model analysis indicated a 5mm space deficiency for the eruption of the first premolar. Further investigations included intraoral photographs and OPG radiographs showing previously treated teeth and space loss.

Diagnosis & Outcomes: The diagnosis was space deficiency due to the migration of adjacent teeth following the premature loss of primary molars. The therapeutic intervention involved the use of a fixed open coil spring space regainer to recover the lost arch space. The treatment was successful, with 5mm of space regained within four and a half months. Follow-up at 6 and 12 months showed the successful eruption of the first and second premolars.

Conclusion: The case underscores the effectiveness of fixed open coil spring space regainers in managing space deficiencies in mixed dentition. The successful use of OCSR demonstrates its reliability and practical benefits over removable appliances, highlighting its value in preventing malocclusion and ensuring proper alignment of permanent teeth in pediatric patients.
