This 34-year-old female patient recently returned for crown restoration of the left maxillary first premolar, which underwent intentional replantation and root canal treatment 20 years ago (Fig. 1C). The left maxillary canine forced eruption began (Fig. 1D), this replanted premolar further endured orthodontic forces and the total treatment period was 26 months. From the 20-year recall periapical radiographs (Fig. 1E and F), we could see that the PDL space was intact.
