Abstract:

Objective

To investigate the role of different teaching methods and the 3D printed replica of the donor tooth in the teaching of tooth autotransplantation.

Methods

The continuing medical education of tooth autotransplantation in 2017-2018 mainly restricted to the theory, including the knowledge and production process of the 3D printed replica and the case reports about tooth autotransplantation. Instead, in 2019, the students taking the same training can prepare an alveolar socket on a plaster model with the assistance of a 3D printed replica and watch the surgery of autotransplantation. The self-made questionnaires were filled out by the students who had participated in the continuing medical education class in 2017-2018 and 2019, from which we would obtain the feedbacks on the effect of different teaching methods and the 3D printed replica of the donor tooth in the teaching of tooth autotransplantation. All the data from the questionnaires were analyzed with Mann-Whitney U test.

Results

Compared with 16 students (51.6%) in 2017-2018, 24 students (80.0%) in 2019 believed that the 3D printed replica of the donor tooth was helpful for postoperative root canal treatment (Z = -2.782, P = 0.005) . In 2017-2018, 5 students (14.3%) believed that patients received excessive ionizing radiation due to the preoperative CBCT examination. In contrast, all students in 2019 agreed on the use of the preoperative CBCT examination (Z = -2.202, P = 0.028) .

Conclusion

The teaching method of the continuing clinical teaching in 2019 was helpful for students to master the application of a 3D printed replica of the donor tooth in the tooth autotransplantation.
