Brief summary

3D printed replicas of the donor tooth can reduce extraoral time during the autotransplantation of teeth, which can reduce dehydration and manipulation of periodontal tissue of the donor tooth, thus possibly increasing the success rate.

Detailed description

This technique of autotransplantation has been innovated using 3-dimensional (3D) imaging and rapid prototyping.The use of a 3D-printed replica of the donor tooth is thought to minimize the risk of iatrogenic damage to the actual donor tooth. Nevertheless, no large prospective and comparative studies are available to assess the outcomes using these 3D techniques. Therefore, this study aimed to compare 3D printed replicas in autotransplantation of teeth, compared to the conventional technique. The present study will evaluate the feasibility, clinical satisfied accuracy, and stability of a novel approach for computer-aided autotransplantation of teeth. This new approach facilitated the surgical procedure and might be a viable and predictable method for autotransplantation of teeth. Application of printed 3D replicas of transplanted teeth facilitates surgical preparation of the recipient site, shortens the extra-alveolar time, and reduces the minimum the number of attempts of the donor tooth insertion at the prepared socket. Their use can significantly decrease the risk of damage to the root surface of a transplant, thus increasing the chance of success.
