Bell CK, et al. - The physicians assessed the accuracy of implants placed using 2 different guided implant surgery materials: thermoplastic vs 3-dimensionally (3D) printed. No significant difference was found in the angular deviations of implants placed with thermoplastic surgical guides compared to those placed with the 3D-printed surgical guide. However, for the implants placed with the 3D-printed surgical guides, the locations of the implant head and implant apex were significantly more accurate compared to those placed with the thermoplastic surgical guides.
