“…Similar to conventional types of DRCs, the quantity, type, size of the inorganic filler [7], and the silanization of the inorganic filler significantly influence the mechanical properties [8]. The mechanical properties of FRCs depend on two main variables: the type of organic matrix [9,10], which gives the mechanical properties of the organic part [11,12], and the inorganic filler [13], characterized by the type, size, and geometry [13,14]. Other factors that influence the mechanical behavior of FRCs are the silanization [8], factors affecting the polymerization efficiency [15,16], and the binding between the inorganic filler and the organic matrix [8,17].…”

The aim of this study was to evaluate the correlation between the percent of inorganic filler by weight (wt. %) and by volume (vol. %) of 11 flowable resin composites (FRCs) and their mechanical properties. To establish the correlation, the quantity of inorganic filler was determined by combustion and shape/size analyzed by SEM images. The compressive strength (CS), flexural strength (FS), and flexural modulus (FM) were determined. The CS values were between 182.87-310.38 MPa, the FS values ranged between 59.59 and 96.95 MPa, and the FM values were between 2.34 and 6.23 GPa. The percentage of inorganic filler registered values situated between 52.25 and 69.64 wt. % and 35.35 and 53.50 vol. %. There was a very good correlation between CS, FS, and FM vs. the inorganic filler by wt. % and vol. %. (R2 = 0.8899–0.9483). The highest regression was obtained for the FM values vs. vol. %. SEM images of the tested FRCs showed hybrid inorganic filler for Filtek Supreme XT (A3) and StarFlow (A2) and a homogeneous type of inorganic filler for the other investigated materials. All of the FS values were above 50 MPa, the ISO 4049/2019 limit for FRCs.

“…Many researchers tried to improve denture base acrylic resins' mechanical properties by adding fillers of different type, sizes, shapes, in different proportions, in order to obtain stronger [22][23][24][25][26][27] and also less brittle materials [28]. Low ductility of dental resins is a key limitation, while increment of both the strength and ductility of matrix composites is still a challenge.…”

PMMA denture base materials are used for several decades without significant improvements in their composition. The addition of different fillers has been proved to improve some of the acrylic resin's characteristics. Recent studies focused on enhancing PMMA properties using nanoparticles. In our study we assessed the effect of adding graphene and silver nanoparticles on the solubility, ductility and resilience of a commercial denture base acrylic resin.

Pure HAP and three doped hydroxyapatites with the same content of Mg, Zn, Si and different contents in Sr were obtained by a wet precipitation method, previously reported [6,10,13,26]. All chemicals were reagent grade procured from Merck and Sigma-Aldrich, solutions were prepared with double distilled water, deionized in Elgastat purification system.…”

The thermal stability over time of the pure and multisubstituted hydroxyapatite (HAP) pastes, doped with magnesium, silicon, strontium and zinc, synthesized using aqueous precipitation method were investigated by thermal analyses (TG-DTA). Results show high thermal stability of pure and multidoped hydroxyapatite pastes, up to 1000 o C and even after ageing for 1 year, making these pastes promising nano materials for medical applications.
