Mechanical Properties and In Vitro Biocompatibility of Hybrid Polymer-HA/BAG Ceramic Dental Materials.

The aim of this study is to prepare hybrid polymer-ceramic dental materials for chairside computer-aided design/computer-aided manufacturing (CAD/CAM) applications. The hybrid polymer-ceramic materials were fabricated via infiltrating polymerizable monomer mixtures into sintered hydroxyapatite/bioactive glass (HA/BAG) ceramic blocks and thermo-curing. The microstructure was observed by scanning electron microscopy and an energy-dispersive spectrometer.

Mechanical properties of polymer-infiltrated-ceramic (sodium aluminum silicate) composites for dental restoration.

Objective: To fabricate indirect restorative composites for CAD/CAM applications and evaluate the mechanical properties.

Methods: Polymer-infiltrated-ceramic composites were prepared through infiltrating polymer into partially sintered sodium aluminum silicate ceramic blocks and curing. The corresponding samples were fabricated according to standard ISO-4049 using for mechanical properties measurement.

Mechanical performance of polymer-infiltrated zirconia ceramics.

Objective: The aim of this study was to evaluate the microstructure and mechanical behavior of polymer-infiltrated zirconia ceramics as a function of pre-sintering temperature (1000-1150°C).

Methods: Polymer-infiltrated zirconia ceramics were prepared by combining the porous zirconia networks and polymer through infiltration and polymerization. XRD was employed to determine phase structure.

High strength and toughness in chromatic polymer-infiltrated zirconia ceramics.

Objective: To evaluate the microstructure and mechanical behavior of polymer-infiltrated zirconia ceramics as a function of FeO concentration (0-0.3mol%).

Methods: Polymer-infiltrated zirconia ceramics with different concentrations of FeO were prepared by infiltration and polymerization.

The Effects of Spark-Plasma Sintering (SPS) on the Microstructure and Mechanical Properties of BaTiO₃/3Y-TZP Composites.

Composite ceramics BaTiO₃/3Y-TZP containing 0 mol %, 3 mol %, 5 mol %, 7 mol %, and 10 mol % BaTiO₃ have been prepared by conventional sintering and spark-plasma sintering (SPS), respectively. Analysis of the XRD patterns and Raman spectra reveal that the phase composition of -ZrO₂, -ZrO₂, and BaTiO₃ has been obtained. Our results indicate that SPS can be effective for the decrease in grain size and porosity compared with conventional sintering, which results in a lower concentration of -ZrO₂ and residual stress.
