Abstract

Objectives: The aim of the study was to evaluate the accuracy of surgical templates for guided implant surgery using 3D printing.
Patients & Methods: Twenty-four patients were examined for implant placement. Each implant site was planned virtually and a 3D printed surgical guide was constructed. The implant had been installed using the 3D printed surgical guide. Postoperative CBCT was performed, and the images were superimposed on the virtual planning images. The amount of coronal, apical, and angular deviation was calculated.
Results: A total of 48 implants were placed in 24 patients. Elven patients were completely edentulous while the other 13 patients where partially edentulous. Mean angular deviation of the implants placed in partially and completely edentulous patients 4.1±0.1 and 3.3±0.78 degrees respectively. While the mean deviation coronally was 1.5±0.3 and 1.1±0.5 mm in partially and completely edentulous patients respectively. The deviation at the apical portion showed a mean 2.1±0.3 and 2.2±0.5 mm in implants placed in partially and completely edentulous patients. Statistical significant difference between the partially and completely edentulous arches where found in coronal and angular deviation while the apical deviation showed no significant difference.
Conclusion: A high accuracy in implant placement can be achieved using 3D printed surgical guide.
