Summary: The aim of this study was to evaluate the fatigue behavior and other characteristics of strength-graded zirconia polycrystals used in monolithic three-unit implant-supported prostheses. Three different prosthesis groups were tested, and their fatigue failure load, the number of cycles until failure, and survival rates were recorded. The graded zirconia showed promising results compared to the bilayer group, with higher fatigue failure load, survival rates, and reliability. The microstructure and composition of the graded zirconia were also analyzed. The study concludes that the strength-graded monolithic zirconia, especially the 3Y-TZP/5Y-TZP, is a promising material for use in implant-supported prostheses.

Summary: This study updated an existing systematic review on the clinical performance of full-arch implant-supported monolithic zirconia fixed dental prostheses. The research found that all 17 included studies reported satisfactory clinical and aesthetic outcomes, with low technical complication rates and high survival rates.

Summary: This in vitro study assessed the effects of different cements and titanium coping designs on the retention of implant-supported fixed dental prostheses (IFDPs). The results showed that quick-set resin provided higher retention force for acrylic resin prostheses. Conical and cylindrical titanium copings performed similarly when cemented to zirconia with Panavia SA cement. The retention force and failure modes were influenced by the cement used.

Summary: This study compared self-glazed zirconia restorations with conventionally CAD/CAM milled and glazed controls and found that self-glazed zirconia restorations have higher surface microstructural homogeneity and fracture strength. The fracture strength of self-glazed zirconia restorations decreased after dynamic loading but remained significantly higher than the conventionally glazed controls. Therefore, this study suggests that self-glazed zirconia restorations are stable for clinical application and further research is needed to prove their clinical applicability.

Summary: This study aims to determine the median event-free survival and complications rates of monolithic and minimally layered full-arch zirconia prostheses, as well as identify risk factors for prosthesis complications. The results show that monolithic and minimally layered zirconia prostheses have an acceptable median event-free survival time, and patients are highly satisfied with these prostheses.

Summary: This retrospective case series evaluated the short-term clinical advantages and limitations of full-arch implant-supported restorations made of monolithic zirconia suprastructures passively luted to titanium bar infrastructures. The study reported a 100% prosthetic survival rate with no implant failures or serviceable prosthetic complications. While two cases showed minor fracture lines in the zirconia suprastructures, no intervention was required. Long-term clinical studies are needed to confirm these outcomes.

Summary: This study evaluated the clinical performance of screw-retained, ceramic-veneered, monolithic zirconia partial implant-supported fixed dental prostheses over a 5-10 year period. The results showed that these prostheses had a favorable long-term survival rate, and over-contoured emergence profile was identified as a significant risk factor for implant failure and biological complications.

Summary: This retrospective study compared the clinical outcomes of single implant-supported crowns and implant-supported fixed dental prostheses (FDPs). It found that mean marginal bone loss around the supporting implants of FDPs was greater than on single implant-supported crowns at one year after implant loading. Biological and technical complications occurred rarely, with screw loosening being the main technical complication observed.

Summary: This study compared the surface characteristics of CAD/CAM high performance polymer and zirconia, and evaluated their effects on stress. The results showed that the high performance polymer had lower surface roughness and higher stress magnitude, but still within an acceptable range.

Summary: This study compared the efficiency and cost of manufacturing implant fixed dental prostheses using three different workflows. It found that the workflow in Test-1 showed the best performance in terms of time-efficiency and production costs, while Test-2 had the worst result. Digital workflows may not necessarily be superior to analog workflows, and simplifying processes can reduce production costs.

Summary: Oral commensal microorganisms have important impacts on the overall health of the host, but they can also contribute to the development of oral and systemic diseases. The colonization of bacteria, fungi, and viruses on removable and fixed prostheses can lead to pathogenic conditions. Inadequate oral hygiene of denture wearers promotes oral dysbiosis and the transition of microorganisms from commensal to pathogens. Hence, it is crucial to maintain daily hygiene of prosthetic products, design prostheses to facilitate home oral hygiene, and use products that reduce plaque accumulation and oral dysbiosis.

Summary: The study characterized the physicochemical and mechanical properties of a milled fiber-reinforced composite for implant-supported fixed dental prostheses. Results showed that FDPs fabricated with milled epoxy resin matrix reinforced with glass fibers demonstrated high probability of survival at 300N load, indicating good fatigue performance.
