Introduction: Ectopic eruption of the first permanent molar is a common anomaly that can lead to premature loss of the second primary molar and malocclusion. Therefore, early diagnosis and treatment are crucial to prevent complications. Case report: A 7-year-10-month-old male patient with ectopic eruption of the maxillary left first permanent molar was diagnosed after the premature loss of the second primary molar. A removable space bridge with a distalizing screw was implanted weekly for 6 months. Radiographically, complete distalization of the first permanent molar and space restoration were achieved. Clinically, the tooth position was corrected, preserving space for the eruption of the second premolar, and adequate long-term occlusion was established. Conclusions: The removable space bridge with a distalizing screw is an effective, low-cost, and easy-to-implement technique for the early treatment of ectopic eruption of the first permanent molar. but it requires commitment and collaboration from the patient and their guardians.
