Objectives: To assess the clinical performance of tooth-supported 3-unit fixed dental prostheses (FDPs) made from shade-graded monolithic 5Y-PSZ (partly stabilized zirconia) zirconia in terms of survival rate and the quality of restorations based on modified FDI criteria over three-years.
Materials And Methods: High-translucent shade-graded monolithic zirconia (Lava Esthetic, Solventum Dental Solutions) was used to manufacture maxillary or mandibular three-unit FDPs in the posterior region (N = 22) employing subtractive milling system (Amann Girrbach). All FDPs were bonded with a universal resin cement (Rely X Universal, Solventum Dental Solutions) and evaluated 4 weeks after cementation (baseline) and after 1, 2, and 3 years.
Article Synopsis
- Changes in CO concentrations impact plant growth and ecosystem functioning, but the adaptation of C photosynthesis to these changes needs more research.
- This study examines the relationship between the photosynthetic capacity of C plants (measured by maximum carboxylation rate and maximum electron transport rate) and species diversification over the last 80 million years.
- It finds positive links between photosynthetic capacity and both species diversification and speciation rates, and notes a shift in these relationships related to CO fluctuations about 30 million years ago, suggesting that historical low CO environments influenced the C photosynthetic pathway's evolution.
Article Synopsis
- * The costs associated with this waste are not only financial but also contribute to antimicrobial resistance and environmental harm.
- * Proposed solutions include switching to oral medications earlier and optimizing pharmacy processes, but more research is needed to confirm their effectiveness; antimicrobial stewardship programs could help implement these changes.
This study aims to assess the dimensional accuracy of complete denture bases fabricated from different CAD/CAM technologies and a conventional method, including milling (CNC), PolyJet (PJ), laser sintering (SLS), digital light processing (DLP), and injection molding (IM). It also examines the influence of the removal of technology-specific connectors or support structures when present. Denture base surfaces were digitized using a laboratory scanner, and virtual measurement points were calculated with tetrahedral reference geometries.
