Summary. The case presented describes the management of a 9-year-old girl with congenitally absent upper lateral incisors and a severely ectopic left maxillary canine. Cone beam CT was used in combination with computer-aided prototyping to produce a surgical template of an immature mandibular second premolar. This was used to prepare the transplant site before the donor tooth was extracted, greatly reducing the time from extraction to implantation. The tooth remains vital at 6 months post-transplant. Compared to previous studies, the use of cone beam CT to create a 3D prototype reduced radiation dose compared to spiral CT and drastically reduced the extra-oral time of the donor tooth from extraction to transplantation.

Comment. Cone beam CT is providing an ever-increasing array of benefits to Paediatric Dentistry. This paper provides an excellent series of images demonstrating the benefits of autotransplantation with the improved surgical procedure brought about by the innovative use of a surgical template formed from a Cone beam CT scan.
