Preliminary preparation for solving delay problems in lower level transparent brace treatment

摘要

A set of pretreatment devices and a set of treatment devices to be worn by the subject are provided. A pre-preparation device is first worn to prepare the local environment of the tooth for additional repositioning of the tooth by the treatment device. The pre-preparation device can compress the periodontal ligament in a desired direction to achieve the desired final position of the tooth. Compression can result in a biological response in the local environment of the tooth. The preliminary device may not cause minimal repositioning of the tooth or cause repositioning. The treatment device can be worn to reposition the tooth from the initial position to the end position of the treatment step. The pre-preparation device can improve the efficiency and accuracy of tooth movement by the therapeutic device.
