case_images: Intraoperative periapical radiograph was advised to confirm the diagnosis which showed caries involving enamel, dentin and pulp with bone loss in the periradicular area (Figs 2A and B). Considering the poor prognosis, extraction of the tooth was planned and to maintain space, "Tube and Loop" SM (Nikhil appliance) was fabricated and delivered as mentioned earlier (Figs 2C and D). Eight months later, the permanent successor (maxillary left second premolar) was found to be erupted uneventfully in its normal position without any space discrepancy (Figs 2E and F).
