Purpose:
It was aimed to apply computer virtual design and digital surgical templates to simulate postoperative position of tooth and guide the accuracy of socket preparation during tooth autotransplantation.
Methods:
The study enrolled 10 patients who underwent tooth autotransplant surgery. Cone-bean CT (CBCT) data were imported into Proplan CMF 3.0 software. The donor tooth was transferred to the recipient site according to the occlusion and space situation. A digital template was designed to guide socket preparation. Computer-aided rapid prototyping (RP) technique was used to print the surgical template and tooth model.
Results:
With computer virtual design and digital template, it was possible to accurately guide socket preparation in recipient site. The six-month follow-up results showed the periodontal space in the radiographs was continuous and intact. There was no mobility in all cases and the probing depth of the tooth was <4 mm. The related data showed a favorable survival and success rates of the donor teeth.
Conclusions:
Computer virtual design can successfully simulate postoperative position in tooth autotransplantation while simplifying the surgical procedure, and enhance the accuracy of socket preparation.
