“…Individualized designs may be created using the additive manufacturing method, and with macrodesign adjustments and surface treatments, the feasibility of using 3D-printed implants has been studied 12 , 19 , 20 . However, the evidence of pros and cons of double-root 3D-printed implants in comparison to the single-root 3D-printed implants is limited.…”

“…The fabrication process of the 3D-printed implants was conducted according to a previous study 16 . In brief, CT datasets of the mandible were obtained using a CT scanner (GE, Boston, USA) and were imported into 3D reconstruction software (Materialise, Leuven, Belgium) via Digital Imaging and Communications in Medicine format.…”

“…Based on a previous study 11,16,18 , damping capacity analysis (Anycheck, Neobiotech, Seoul, Korea) was performed at implant placement and at every two weeks following until 12 weeks to measure implant stability. Measurements were taken five times from the buccal side of each implant, and the average value was considered representative.…”

“…The data were reconstructed with the manufacturer's software (DataViewer 1.5.2.4 64-bit version, Bruker micro-CT, Skyscan, Kontich, Belgium) and quantitatively analyzed with CTAn (Bruker-CT, Kontich, Belgium). Based on a previous study 16 , the volume of interest (VOI) was set to a 190-μm circular band stretching 60-2250 μm from the implant surface of each root, limiting 1 mm to 4 mm above the fixture apex.…”

“…3D-printed implants with multiple roots in the posterior region have been suggested as an alternative to alleviate the mechanical complications of conventional implants and regenerative procedures. Recently, we investigated 3D-printed double-root implants designed under a digital workflow with digital data, software, and fabricated with a direct metal laser sintering machine using Ti-6Al-4V powder in vivo 16 . From this study, we found that the macrodesign of a 3D-printed implant with a groove has a significant positive effect on secondary implant stability.…”

Recently, double-root implants have been investigated using 3D-printed technology. Here, we investigated damping capacity, microcomputed tomographic (micro-CT) and histological analyses of double-root 3D-printed implants compared with single-root 3D printed implants. Single- and double-root 3D-printed implants were fabricated and placed at both sides of mandibular third and fourth premolars in four beagle dogs. The damping capacity was measured, and periapical X-rays were taken every 2 weeks for 12 weeks. The bone volume/tissue volume (BV/TV) and bone mineral density (BMD) around the implants were measured with micro-CT. Bone-to-implant contact (BIC) and bone area fraction occupancy (BAFO) were measured in histological samples. The implant stability values between the groups were not significantly different, except at 4 and 12 weeks. The marginal bone changes were similar at the mesial and distal areas between the groups. The BV/TV and BMD values of the double-root 3D-printed implants showed no statistical difference through micro-CT analysis, but the double-root 3D-printed implants showed lower BIC and BAFO values through histomorphometric analysis compared to the single-root 3D-printed implants. Compared to single-root implants, 3D-printed double-root implants demonstrated comparable stability and bone remodeling around the fixtures, but the statistically significant bone loss in the furcation area remains problematic.
