There are various forms of dental trauma that occur in childhood. In the subgingivally crown-root fracture case, forced eruption has been depicted as one of the most conservative treatments. Generally, the forced eruption is done by using wires, power chains, elastic threads, or using removable appliances and elastic. However, due to the characteristics of pediatric patients, it is difficult to obtain the patient's cooperation and maintain clean oral hygiene status. As an alternative, forced eruption using MTA (Mini-Tube Appliance) can be proposed. This case report describes two cases of subgingivally crown-root fracture, which were treated with modified MTA to form a customized resin tube to perform a treatment more aesthetic, rapid, and stable.
