Abstract

Background

This study evaluated the accuracy of dental surgical guide templates manufactured using CAD/CAM and 3D printing.

Materials and Methods

A partially edentulous dental casted model was prepared as a reference model. Through CBCT, virtual implant positions were planned using the MIRDC Dental software, and this implant position information formed the surgical guide template information. CAD/CAM and 3D printing fabricated the surgical guide template. Two indexes were calculated for surgical guide template assessment, including the deviations of planned and placed implants and the fitness between the template and dental model.

Results

The experimental results show that the overall average error of the 3D printing method is 0.493mm, the general average error of the CAD/CAM guide plate is 0.66mm, the precision of the 3D printing processing method is higher, and the average error of the bonding surface is 0.425mm. The accuracy of the CAD/CAM method is slightly lower than that of 3D printing. However, its precision value is still in line with clinical use, and its precision is still clinically acceptable.

Conclusion

The 3D printing surgical guide template proved to be highly accurate, and the accuracy of this method can quickly assist clinicians in evaluating implanted results.
