The development of 3D-printed crown resin materials with improved mechanical and physical properties is an area growing interest in dentistry. This study aimed to develop a material modified zirconia glass (ZG) silica (GS) microfillers enhance overall properties. A total 125 specimens were created divided into five groups: control unmodified resin, 5% either ZG or GS reinforced 10% resin. fracture resistance, surface roughness, translucency parameter measured, fractured crowns studied under scanning electron microscope. results showed that parts strengthened demonstrated comparable performance but resulted greater only the group contained increase translucency. However, it should be noted increased roughness may impact aesthetics crowns, further optimisation concentrations necessary. These findings suggest newly developed dental-based resins incorporate could suitable for clinical applications, studies are necessary optimise nanoparticle investigate their long-term outcomes.

Uniform filler distribution in composites is an important requirement. Therefore, BaO glass, nano hydroxyapatite and quartz was realized through PCL microcapsules which progressively release during matrix polymerization. Two were based on a complex containing BisGMA, UDMA, HEMA PEG400 mixed with previously described mineral filler: 33% for C1 31% C2. The spreading efficiency observed via SEM, revealing complete disintegration of the polymerization, while C2 preserved some microcapsule parts that well embedded into beside particles; this confirmed by means EDS spectra.
