This study aimed to assess how the physical and mechanical properties of dental composites are influenced by the characteristics of natural material fillers. We focused on analyzing the filler properties (using XRD, FTIR, SEM, BET, and density) of a selection of glass materials to identify correlations with their physico-mechanical properties and to evaluate the validity of the current classification system. Filler particles measuring less than 500 nm were extracted from five different composites. The surfaces of these fillers were modified with silane before being mixed with a Bis-GMA/TEGDMA (70/30%) resin. We evaluated the physico-mechanical properties of the tested composites, including depth of cure, void content, flexural strength, compressive strength, and fracture toughness. The average size of the fillers was consistently below 1 µm. Flexural strength values ranged from 70.56 to 110.81 MPa, Due to the solid ceramic characteristics of Aluminiumsilicate, certain mechanical properties, like compressibility, may experience a slight increase as the amount of Aluminiumsilicate decreases.
