Objective

  To compare the outcome of cone beam computed tomography (CBCT)–based surgical planning and transfer technique for tooth autotransplantation versus conventional autotransplantation.

 Study Design

  The study material comprised 40 pediatric subjects in whom 48 teeth were transplanted following a case–control design. While the study group (mean age 11 years) underwent CBCT imaging for surgical planning and transfer via stereolithographic tooth replica fabrication, the historical control group (mean age 12 years) was subjected to conventional autotransplantation.

 Results

  The CBCT-based preoperative planning and the use of a tooth replica decreased the extra-alveolar time and reduced the number of positioning trials with the donor tooth. In the control group, 6 patients showed 1 or more complications, while this was noticed for only 2 study patients.

 Conclusion

  CBCT-based surgical planning of tooth autotransplantation may benefit from a shorter surgical time, while being a less invasive technique, causing fewer failures than a conventional approach.
