“…Composite materials with a micro-filter have a tensile strength from 30 to 56 MPa, and composite materials with a macro-filler from 35 to 50 MPa [24]. The tensile strength of composite materials is comparable to that of amalgam, which is 60 MPa [1,23,[25][26][27].…”

“…Most of the composite materials, in addition to the essential components, contain monomers such as HEMA, EGDMA, DEGDMA, and TEGDMA, which are lower molecular weight compounds. In addition to the substances mentioned above, composite materials include initiators, activators, and additives required in the polymerization process, e.g., light stabilizers [1][2][3].…”

Complex composite materials are used in many areas of dentistry. Initially, chemically hardened materials were also used, and in this group nanohybrid composites are highly valued. They are often used today, mainly for the direct reconstruction of damaged hard tooth tissue materials for rebuilding damaged tissues using indirect adhesive techniques. The research was conducted to determine the mechanical properties of materials with nanofillers. The article focuses on methods of important test methods for dental prosthetics: resilience, abrasion, wear test, impact strength, hardness, SEM, and chemical analysis. As part of this work, five different series of hybrid composites with nano-fillers were tested. The mechanical properties of composites, such as compressive strength, microhardness, flexural strength, and modulus of elasticity, depend mainly on the type, particle size, and amount of filler introduced. The obtained test results showed that the type and amount of nanofiller have a significant influence on the mechanical and tribological properties. The introduction of nanofillers allowed us to obtain higher mechanical properties compared to classic materials discussed by other researchers. The study observed a change in vibrations in the IR spectrum, which allowed a comparison of the organic structures of the studied preparations.

“…The evaluation in current study of water sorption (WS) and water solubility (SL) have been made in accordance with the ISO 4049 standard. WS and water SL values of resin composites should not exceed 40 ug/mm 3 and 7.5 ug/mm 3 respectively according to ISO 4049 [17,21]. All the tested resin composites materials in this study met these criteria.…”

“…In general terms, WS and SL also correlates with the type of the ller [13]. BU contained "pre-reacted glass ionomer (PRG)"-based uoro-alumina-silicate glass, which is assuming to release and recharge uoride by absorbing a certain amount of water [21]. Besides, giomer composites might have more surface vacancies via the release of uoride ions [25].…”

Objectives To evaluate the physico-mechanical properties, including water sorption (WS) and solubility (SL), flexural strength (σf) and modulus of elasticity (Emod), as well as Vickers hardness (VHN) value of most currently available aesthetic resin composites by comparing them with conventional resin composite. Materials and methods Universal-shde resin composite OMNICHROMA (OMNI; Tokuyama), Beautifil Unishade (BU; Shofu), Essentia (EN; GC), and A3 shade of aesthetic resin composites Harmonize (HM; Kerr), conventional resin composite Tetric N Cream (TNC; Ivoclar Vivadent) were evaluated in this study. Volume and weight were recorded every 24 h of water immersion of resin composites (n = 5) for the calculation of WS and SL. Bar shaped specimens were sectioned from each material (n = 5), Emod and σf were evaluated using a three-point bending test. Bottom and top of the specimens (n = 3) of VHN were obtained for three spots using Vickers micro-hardness tester. Afterwards, bottom-top hardness ratio was calculated. One-way ANOVA, Tukey’s test, Kruskal-Wallis, Pearson’s correlation test, and Paired-samples t-test were computed (p < 0.05). Results HM showed significant the highest WS and SL (p < 0.05). There was no significant difference in σf regarding the materials (p > 0.05). BU showed significant the highest Emod (p < 0.05). HM recorded the highest VHN value (p < 0.05), and significantly the lowest bottom-top hardness ratio (p < 0.05). Conclusions The aesthetic resin composites showed comparable physico-mechanical properties compared to conventional resin composite TNC. Clinical relevance The physico-mechanical properties of resin composite material influence the long-term clinical performance of the restoration.

“…Various research groups have already established that the behavior of dental resins is influenced by the corrosive influence of water and/or by the periodic masticatory stresses that are applied to the material. Elution, deterioration, relaxation, accelerated crack growth, visco-elastic effects, and decreased wear resistance are all potential outcomes that might be brought about by these causes [ 31 , 44 , 45 , 46 ].…”

One therapeutical alternative in the treatment of functional disorders is the use of printed oral splints. The mechanical properties of these materials are highly essential to their clinical effectiveness, and their performance may vary depending on factors such as cleaning, post-polymerization, or their orientation during construction. The objective of this in vitro investigation is to evaluate the effectiveness of the selected materials in terms of their biaxial flexural strength in relation to the criteria listed above. Splint materials were used in the printing of 720 discs. The printing process was carried out in different orientations in relation to the building platform. Either an automatic or manual cleaning process was performed on the samples. For post-polymerization, either an LED or Xenon light was utilized. A piston-on-three-ball test was used to measure the biaxial flexural strength (BFS) of the materials after they were stored in water for either 24 h or 60 days. The homogeneity of the data was controlled by employing the Levene method, and the differences between the groups were analyzed using the ANOVA and Bonferroni methods. After being stored for twenty-four hours, the mean BFS ranged anywhere from 79 MPa to 157 MPa. Following a period of sixty hours, the BFS exhibited a substantial drop and revealed values that ranged from 72 to 127 MPa. There was no significant difference that could be identified between the materials or between the various cleaning processes. The results of post-polymerization showed that the LED light produced higher means than the Xenon light did. In terms of position, the mean values varied greatly, with 0°’s mean value being 101 MPa, 45°’s mean value being 102 MPa, and 90°’s mean value being 115 MPa. The use of a build orientation of 90° and post-polymerization with LED light resulted in significantly increased biaxial flexural strength. According to this study, this design should be implemented in order to ensure that splint materials have the highest possible strength.
