“…The materials used to bond this type of restoration include light-cured [16,19,22,23,25], dual-cured composite resin cement (in light-curing mode) [10,20,21,24], and pre-heated restorative composite resin [15]. The lower inorganic filler content found in lightcured and dual-cured resin cement (approximately 60% to 77.2% weight) [43][44][45][46], when compared to pre-heated composite resins (80% weight) [47], may explain their higher susceptibility to abrasive wear and hydrolytic degradation processes. Because the main monomers of most composite resin cement reported in this review include ester, ether, urethane, and hydroxyl groups, higher water sorption is expected [48,49].…”

Study selection: Partial laminate veneers, defined as small ceramic restorations adhesively luted onto unprepared anterior teeth, are an interesting and conservative alternative to conventional ceramic and composite resin veneers in the anterior region. This literature review aimed to summarize the available laboratory and clinical data on ceramic partial laminate veneers. An electronic search of the MEDLINE/PubMed, EBSCO, and Web of Science databases was conducted. The keywords used were "partial veneer," "partial laminate veneer," "ceramic fragment," and "sectional veneer." The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. The risk of bias in the included studies was assessed using the QUIN tool. Results: Of the 266 identified articles, only 16 met the inclusion criteria (ten clinical reports, five laboratory studies, and one retrospective clinical study). To date, no randomized controlled clinical trials have been conducted. Most laboratory studies displayed a low risk of bias, with partial laminate veneers rendering adequate strength and color stability. Clinical reports have shown large variability in material selection, luting, and finishing/polishing protocols. Conclusions: Low-quality evidence is available for ceramic partial laminate veneers. Available data from laboratory studies suggest good mechanical and optical performances comparable to those of conventional ceramic and composite resin veneers. Further clinical studies with longer follow-up periods are warranted.

“…The color stability of the SUF resin composites was the best of all of the flowable resin composites evaluated, followed by OCF, and finally GLF. Water solubility could be attributed to discoloration by chemically degrading the filler-resin bond of the resin matrix [30]. Some previous studies concluded that water sorption and filler loading had a strong correlation [31,32].…”

Background: This study aimed to evaluate the color matching, light transmittance, and reflectance characteristics of the novel flowable resin composite OCF-001 (OCF). Methods: Fifty-four resin composite molds were made with simulated class I cavities of A2, A3, and A4 shades by filling the rubber mold interspace with Estelite Sigma Quick (ESQ), Gracefil Putty (GP) and Filtek Supremme Ultra (FSU). After applying the adhesive, three different flowable resin composites (n = 6), OCF, Gracefil LoFlo (GLF), and Supreme Ultra Flowable (SUF), were used to fill the cavities. A colorimeter was used to measure the color parameters (CIEDE2000). The color measurements were taken immediately and after 28 days. Data were analyzed using the nonparametric Kruskal–Wallis (α = 0.05) and Wilcoxon tests. The light transmittance and reflection characteristics were measured with a black background using a spectrophotometer under D65 illumination. Results: The ΔE00, and ΔC of OCF was lower than other tested materials in A2 and A3 shades both immediately and after 28 days. OCF showed the highest transmittance characteristic, and a relatively stable reflectance curve in all the wavelengths. Conclusions: OCF showed better shade matching with the surrounding shades of A2 and A3, a relative uniform reflectance and higher light transmission properties.

“…Light-cured resin cements (LC) are advocated as the primary choice for aesthetic restorations thinner than 1.5 mm [8,9]. This recommendation is primarily based on their enhanced shade matching and long-lasting colour stability beneath highly translucent restorations, as compared to the yellowing effects associated with dual-and self-cured varieties [6,10,11]. However, thicker aesthetic restorations (2-3 mm) require the use of dual-cured (DC) resin cements [12,13].…”

“…The quality of the polymerised cement is also influenced by its intrinsic characteristics, such as: filler particles, polymer matrix, initiator composition and concentration [11,[35][36][37]. A new amine-free photoinitiator with improved lighter shades and discolouration resistance, Ivocerin™ (Ivoclar Vivadent), has been introduced for their light-and dual-cured aesthetic resin cements.…”

“…A new amine-free photoinitiator with improved lighter shades and discolouration resistance, Ivocerin™ (Ivoclar Vivadent), has been introduced for their light-and dual-cured aesthetic resin cements. Some recent investigations found these Ivocerin™ containing cements to be favourable in terms of degree of conversion, flexural strength and bond strength to dentin [7,38], but comparable to conventional cements with regard to water sorption and colour stability [11].…”
