Exclusion criteria

Exclusion criteria: 1.Root length (the distance from the cementoenamel junction to apex) of maxillary incisors was less than 9 mm in T0 CBCT 2.Low CBCT image quality the cortical bone and root could not be defined accurately.

Design outcomes

Primary

MeasureTime frame
to assess if lowerly positioned incisive canal will contact upper incisor roots after retractionTimepoint: data will be collected at baseline and after 10 months—

Secondary

MeasureTime frame
To evaluate whether contact between the upper incisor root & the incisive canal can result in root resorption.Timepoint: data will be collected at baseline & after 10 months—
