Summary

Hybrid composites with increased submicron silica content show improved physical strength for dental restorations. Higher filler loading at 25% submicron silica yielded the best results, enhancing wear resistance.

Background:

Hybrid composites are widely used for posterior dental restorations due to their wear resistance.
Optimizing filler composition is crucial for enhancing the physical properties of these restorative materials.

Purpose of the Study:

To investigate the impact of varying submicron silica content on the physical properties of a hybrid composite.
To evaluate the relationship between filler loading and mechanical performance in a Bis-GMA based resin system.

Main Methods:

A Bis-GMA based resin system was formulated with varying percentages of submicron silica (0.04 microns) and semiporous strontium glass.
Physical properties, including strength measurements, were assessed across different filler compositions.
Filler loading was systematically increased with higher submicron silica content.

Main Results:

Increasing submicron silica content led to higher overall filler loading in the composite.
The highest physical strength measurements were observed at the 25% submicron silica level.
Diametral Tensile Strength (DTS) remained relatively consistent across a range of 5-40% submicron silica.

Conclusions:

Hybrid composite formulations with optimized submicron silica content can enhance physical strength for dental applications.
The 25% submicron silica level appears to be optimal for maximizing filler loading and physical properties.
Further research may explore tailoring filler compositions for specific mechanical property requirements in dental composites.
