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.
