Figure 1 Preoperative photos and computed tomography scan of the donor and the recipient. A and B: Occlusal photos showing the recipient’s missing #26; C and D: Occlusal photos showing the donor’s #48; E: The recipient’s orthopantomogram taken before the surgery; F: Computed tomography image showing the cross section of the bone at #26.

Figure 2 Individual drill compared with donor’s tooth. A: The 3D image of the donor’s tooth was extracted from the cone beam computed tomography, a computer-aided design model was built using measuring instrument to gather information for the shape and size, and an individual drill was manufactured by direct metal laser sintering; B: The cross section comparison of the individual drill and the donor’s tooth; C and E: The model of the drill in the recipient’s alveolar bone; D and F: The model of the donor’s tooth in the recipient’s alveolar bone.

Figure 3 Surgical procedure. A: The donor’s tooth was extracted, then the attached gingival was gently removed, but the periodontal ligament was kept; B: Treatment with solutions of 10 g/L cephalosporin, 75 g/L clindamycin hydrochloride, and 50 g/L aspirin in sequence; C: Soft tissue reflection; D: Expanding the pilot hole by using progressively wider drills; E: Finishing the preparation by using the individual drill; F: Collecting the autogenous bone during the hole preparation; G and H: Applying the autogenous bone to fill the compartment; I and J: Transplanting the tooth to the recipient’s site; K: Suture; L: Splinting the tooth with an acid-etch resin composite splint.

Figure 4 Periapical radiographs of the transplanted tooth after surgery. A: One day after transplantation; B: One week after transplantation; C: One month after transplantation, inflammatory resorption and replacement resorption were progressing; D: Two months after transplantation; E: Three months after transplantation; F: Four months after transplantation, inflammatory resorption and replacement resorption were stable, and there was no appearance of normal periodontal ligament up to this time; G and H: Photos showing the transplanted tooth four months after surgery.
