“…Suzaki et al [ 18 ] tested the water absorption of Trinia, a fiber-reinforced composite (everX posterior, GC) and a conventional composite (Beauti core flow paste, SHOFU) by immersing the samples in water at 37 ◦ C for 7 days. The lowest water absorption (4.7 ± 1.9 g/mm 3 ) was found in Trinia out of all three materials.…”

“…Trinia™ (BICON, Boston, MA, USA) is a fiber-reinforced dental composite for permanent computer aided design and computer aided manufacturing (CAD/CAM) milled dental prosthetic rehabilitations, presented as discs and/or blocks, and it represents an alternative to conventional technological methods. It is a metal-free reinforced dental composite, formed of multidirectional interlacing of a fiberglass and resin matrix in several layers, that has high flexural strength and a flexural modulus of elasticity similar to dentin [ 17 , 18 , 19 ]. The properties and versatility of Trinia™ reinforced composites permit their use for permanent dental prosthetic restorations because of their relatively simple design and manufacturing by using CAD techniques.…”

Fiber-reinforced composites are used as restorative materials for prosthetic oral rehabilitation. Gastroesophageal reflux disease (GERD) is an accustomed affection with various oral manifestations. This study aimed to evaluate the behavior of two high-performance CAD/CAM milled reinforced composites (Trinia™, TriLor) in artificial saliva at different pH levels through immersion tests, and to determine if changes in mass or surface morphology at variable pH, specific for patients affected by GERD, appear. After investigating the elemental composition and surface morphology, the specimens were immersed in Carter Brugirard artificial saliva for 21 days at different pH values (5.7, 7.6, and varying the pH from 5.7 to 3). The values of the weighed masses during the immersion tests were statistically processed in terms of mean and standard deviation. Results suggested that irrespective of the medium pH, the two composites presented a similar mass variation in the range of −0.18 (±0.01)–1.82 (±0.02) mg after immersion, suggesting their stability when in contact with artificial saliva, an aspect which was also highlighted by scanning electron microscope (SEM) analysis performed on the immersed surfaces. Novel composite biomaterials can be a proper alternative for metal alloys used for prosthetic frameworks in patients suffering from GERD.

“…Development in digital technology in recent years has significantly improved the production of indirect restorations, in particular CAD/CAM restorations. These types of restorations can be produced by milling of composite or ceramic blocks [1]. CAD/CAM composites offer some advantages, as they are more flexible and less fragile than glass ceramics [2].…”

The aim of this study was to assess the shear-bond strength (SBS) of resin-luting cement to experimental short fiber-reinforced CAD/CAM composite (SFRC) compared to conventional CAD/CAM (Cerasmart 270), 3D printed (GC TEMP PRINT, Pro3dure GR-17), and laboratory (Gradia Plus) composites. Moreover, translucency parameter values and light transmission were evaluated. For each of the five types of composites, discs were prepared (n = 16/group) and divided into subgroups (n = 8/group) according to surface treatment protocol (hydrofluoric acid or airparticle abrasion). SBS test was performed using universal testing machine until failure, and failure modes were visually analyzed. Translucency parameter and curinglight transmission values through 1, 2, and 3 mm thickness were quantified using spectrophotometry and the MARC resin calibrator, respectively. Scanning electron microscopy (SEM) was used to examine the CAD/CAM composites after surface treatment. Composite type and surface treatment had a significant effect on SBS. Laboratory composite showed the highest SBS value (22.4 MPa). Cerasmart 270 exhibited higher translucency parameter values (19.8, 11.0, 5.0) than SFRC (14.5, 5.2, 1.6) at the three composite thicknesses tested. Air-particle abrasion was more effective in enhancing SBS than acid etching. Experimental SFRC CAD/CAM composite showed higher SBS values than Cerasmart 270. For all composites, translucency parameter values and light transmission decreased as thickness increased.

“…In our previous study, TRINIA was shown to have distinct anisotropy and that it can be used as a superior restorative material by ensuring specific directions of its fiber mesh layers [ 7 ]. The anisotropy of TRINIA is totally different from that of conventional fiber post-cores along to longitudinal axis and possibly support for thin remain dentin.…”

The prevention of root fractures of pulpless teeth is an important clinical issue to maintain healthy teeth through lifetime. The aim of this study was to examine a clinically effective treatment method for strengthening vulnerable pulpless teeth using CAD/CAM (computer-aided design/computer-aided manufacturing) fiber-reinforced post-core by conducting a fracture resistance test. A post-core made with a fiber-reinforced resin disk TRINIA (TR, SHOFU, Kyoto, Japan) was fabricated using a CAD/CAM system. The fiber-layer orientation of the CAD/CAM post-core was parallel to the axis of the restored tooth. A post-core using a conventional composite and a fiber post (CF) was also prepared. A fracture resistance test of teeth restored with the post-cores and zirconia crowns was conducted using a universal testing machine, and fracture patterns were identified by micro-CT observation. The fracture load of the roots restored with TR was 1555.9 ± 231.8 N, whereas that of CF was 1082.1 ± 226.7 N. The fracture load of TR was 43.8% that was significantly higher than that of CF (Student’s t-test, p < 0.05). The restored teeth with CAD/CAM resin post-core were found to be repairable even after fracture. These results suggest that the CAD/CAM indirect fiber post-core has the potential to strengthen the vulnerable pulpless teeth.
