“…Zirconium oxide is a material characterized by high mechanical strength, crack resistance, high biocompatibility and good aesthetic effect. The features of this material allow it to be often used in dentistry for making small permanent restorations such as inlays, onlays or overlays, as well as crowns and extensive bridges based on teeth or dental implants [ 6 , 7 , 8 ].…”

Background: The aim of this in vitro study was to determine the mechanical and functional properties of zirconium oxide ceramics made using 3D printing technology and ceramics produced using conventional dental milling machines. Methods: Forty zirconia samples were prepared for this study: the control group consisted of 20 samples made using milling technology, and the test group consisted of 20 samples made using 3D printing technology. Their surface parameters were measured, and then their mechanical parameters were checked and compared. Density, hardness, flexural strength and compressive strength were tested by performing appropriate in vitro tests. After the strength tests, a comparative analysis of the geometric structure of the surfaces of both materials was performed again. Student’s t-test was used to evaluate the results (p < 0.01). Results: Both ceramics show comparable values of mechanical parameters, and the differences are not statistically significant. The geometric structure of the sample surfaces looks very similar. Only minor changes in the structure near the crack were observed in the AM group. Conclusion: Ceramics made using additive technology have similar mechanical and surface parameters to milled zirconium oxide, which is one of the arguments for the introduction of this material into clinical practice. This in vitro study has shown that this ceramic can compete with zirconium made using CAD/CAM (Computer-Aided Design and Computer-Aided Manufacturing) methods.

“…20 Despite wide clinical use of translucent zirconia for full-arch implant prostheses, with increased translucency of the material its flexural strength and fracture toughness is greatly diminished, which may lead to an increased incidence of prosthesis fracture compared to high-strength opaque zirconia and this side effect needs to be addressed. 21,22 The development of CAD/CAM software and technologies allowed to digitally manage the design of the final prosthesis to combine two diverse materials, as an overlaying monolithic translucent zirconia and a metal substructure. [23][24][25][26][27][28][29] The zirconia and titanium transmucosal surface characteristics allowed for a highly polished interface, that exhibited lower surface free energy and lesser surface wettability, reducing bacterial adhesion, 30 promoting excellent cell adhesion, thus playing an important role in maintaining gingival architecture for FP1 prosthesis.…”

ObjectiveDespite the wide clinical use of translucent zirconia for full‐arch implant prostheses, reduced flexural strength and fracture toughness compared with high‐strength opaque zirconia needs to be addressed. A novel proof of concept for FP1 full‐arch prosthesis featured by translucent monolithic zirconia and titanium framework was presented.Clinical ConsiderationsComputer‐guided implant planning and surgery were executed and digitally designed FP1 temporary prosthesis prefabricated. Implant and prosthetic placement were achieved with a set of three‐dimensional (3D)‐printed templates. Implants were immediately loaded. After 4 months intraoral optical scan was taken to record implant coordinates, soft tissue anatomy, and temporary FP1 prosthesis. A novel digital workflow was used to design and mill overlaying translucent zirconia and anatomically shaped titanium framework with a scalloped soft‐tissue interface. Final FP1 prosthesis was assembled cementing zirconia jacket on titanium counterpart.ConclusionsTranslucent zirconia supported by titanium framework can address esthetic and mechanical requirements of FP1 full‐arch prosthesis, minimizing risk of fracture and providing a rigid and passive joint with supporting implants. The smooth and highly polished titanium surface with an anatomic design, tightly matching scalloped soft tissue interface, can limit food impaction, air and saliva leakage and contribute to overall biologic integration of FP1 full‐arch prosthesis.Clinical SignificanceTranslucent monolithic zirconia featured with anatomically shaped titanium framework with scalloped transmucosal part, combining a pleasant esthetic outcome with increased flexural strength and fracture toughness, may be indicated to increase the clinical performance of FP1 full‐arch prosthesis.
