Objective: To evaluate the flexural strength and fatigue behavior of a novel 3D-printed composite resin for definitive restorations. Materials and methods: Fifty disc-shaped specimens were manufactured from each of a nanohybrid composite resin (NHC), polymer-infiltrated ceramic network (PICN), and 3 ...

The reaction of aluminum nitride (AlN) powder with water has been known for a long time. In the presence of water AlN will decompose, forming aluminum hydroxide and ammonia:
AlN + 3H2O → Al(OH)3 + NH3
Bowen et al.1 proposed more detailed reaction scheme for the reaction of AlN powder with water ...

Nekoč, približno tri tisoč let pred našim štetjem, so na Ljubljanskem barju živeli koliščarji. Za seboj so pustili veliko zanimivih predmetov, med drugim tudi keramični kipec (»Ižanski idol«) iz črne žgane gline, ki ga hranijo v Narodnem muzeju v Ljubljani. Odkrit je bil na bakrenodobnem kolišču v b ...

ranslucent zirconia;nanostructured alumina coating;airborne-particle abrasion;
Thin, non-retentive, monolithic restorations fabricated from novel translucent zirconia ceramics are widely used in contemporary dentistry. Because of the chemical inertness of zirconia, debonding of such restorations remains the main clinical complication. Limited evidence on the bonding performanc ...

Some transition metals and their alloys have the ability to reversibly absorb considerable amounts of hydrogen. The amount of absorbed hydrogen and the absorption kinetics depend on interactions between the hydrogen atoms and the alloy. Titanium and zirconium show a high affinity for hydrogen, and T ...

Uvod: Titan in njegove zlitine so trenutno najbolj uporabljeni biomateriali za zobne vsadke, zaradi kombinacije lastnosti, ki vključujejo visoko odpornost proti koroziji, biokompatibilnost, ponovno pasivizacijo in ustrezne mehanske lastnosti. Vendar pa tudi titan in njegove zlitine kljub biokompati ...

The heat treatment of dental alloys prior to porcelain application/veneering has been proposed as a way to ensure sufficient oxide scale and to promote the porcelain's adherence in porcelain-fused-to-metal (PFM) fixed dental prostheses. The present study investigates the relationship between the bon ...

Freeze-casting is a powerful consolidation technique for the fabrication of highly porous and layered-hybrid materials, including ceramic-metal composites, and porous scaffolds for catalysis, bone substitutes and high- performance membranes. The aqueous suspensions to be freeze-casted usually contai ...

Hydraulic calcium silicate-based cements (HCSCs) have become a superior bioceramic alternative to epoxy-based root canal sealers in endodontics. A new generation of purified HCSCs formulations has emerged to address the several drawbacks of original Portland-based mineral trioxide aggregate (MTA). T ...
