Special Issue Information

Dear Colleagues,

As dentistry evolves, especially the prosthodontics field, new materials and techniques emerge on a daily basis. In this sense, the upward development aims to improve the clinical longevity of indirect restorations by modifying the adhesive techniques and materials employed. More conservative approaches arise by using materials with the capability of mimicking the natural dental structure, enhancing both the functionality and esthetics of rehabilitation treatments. These advancements not only promise increased durability and performance of dental indirect restorations, but also emphasize minimally invasive procedures that prioritize the preservation of natural tooth structure. Alongside that, the use of new technologies to produce indirect restorations is directly connected with current materials, inducing a process with high precision and solutions focused on patient-specific needs, further enhancing treatment outcomes.

Considering the novelty of such topics, there is a notable lack of comprehensive data to fulfil the knowledge gap concerning new materials and adhesive techniques in prosthodontics. Thus, this Special Issue will delve into the latest innovations in adhesive dentistry, exploring cutting-edge materials, novel bonding methods and their clinical applications in prosthodontics. We invite authors to contribute original research articles, reviews and case studies that examine the development and performance of new adhesive systems, and their impact on the longevity and esthetics of dental restorations. By sharing your expertise and findings, you can help shape the future of prosthodontics and contribute to the collective knowledge that drives this dynamic theme forward.

Background/Objectives: Corrosion resistance of dental alloys, indicated by metal ion release, is a significant concern. The aim of this study was to investigate the impact of various sandblasting methods on the corrosion resistance of Co-Cr-W alloy samples in an artificial saliva solution. Materials and Methods: Co-Cr-W samples, obtained by additive manufacturing (selective laser melting) and subjected to different processes, were evaluated using electrochemical corrosion tests on potentiostat equipment in Carter–Brugirard artificial saliva. All measurements were conducted at a temperature of 37 °C. The morphology of the samples was analyzed using scanning electron microscopy to highlight changes in roughness and the effects of the electrolyte solution on the surface of the samples. Results: The corrosion current density values decreased as surface processing increased, dropping from an average of 38.5 μA/cm2 in non-sandblasted samples (group A) to 0.74 μA/cm2 in samples sandblasted with both Al2O3 and glass particles (group C), while the corrosion rate of group A (434.8 mm/year) was significantly higher than that of group C (8.08 mm/year). Conclusions: The results demonstrated different behaviors between sandblasted and non-sandblasted samples, which could be attributed to surface morphology differences influencing the corrosion process.

Objectives: This study evaluates the effectiveness of laser surface texturing (LST) using a Surface Transition Machine (STM) on pre-sintered zirconia, comparing its impact on surface characteristics and shear bond strength (SBS) with resin cement to conventional sandblasting techniques. Methods: Zirconia specimens were treated with either STM or sandblasting, followed by surface analysis through scanning electron microscopy (SEM) and White Light Interferometry (WLI), wettability assessment via contact angle measurements, and SBS testing with resin cement and a 10-MDP-containing primer. Results: SEM and WLI revealed significant surface alterations in STM-treated zirconia, producing microscale textures. STM-treated surfaces exhibited significantly lower contact angles (28.4 ± 10.0°) compared to untreated (78.2 ± 8.0°) and sandblasted (79.2 ± 5.7°) surfaces, indicating enhanced wettability (p < 0.05). SBS was highest in the STM with primer group (46.3 ± 8.3 MPa) and STM without primer (43.4 ± 4.3 MPa), both of which significantly outperformed sandblasting with primer (30.06 ± 3.09 MPa) and sandblasting alone (9.8 ± 3.7 MPa) (p < 0.05). Conclusions: These findings suggest that STM-based LST is a more effective method for improving zirconia surface characteristics and adhesion in dental restorations, simplifying bonding procedures, and potentially offering better clinical outcomes than conventional sandblasting.

Background: The optimum bond strength of glass fiber posts can be compromised; it has not yet been established which final irrigant, when used in combination with luting cement, can improve this bond strength. Objectives: This study assessed the effectiveness of 2% chitosan as a final irrigant in combination with different types of luting cement used to improve the bond strength of glass fiber posts bonded to root canal-treated teeth. Methods: Thirty single-rooted anterior teeth were collected and sectioned 2 mm above the most incisal point of the cementoenamel junction. After root canal filling, post spaces were prepared and irrigated in Group I using 17% EDTA for 3 min and in Group II using 2% chitosan for 3 min. Each group was divided into three subgroups: Fiber posts were cemented in subgroup A with Fuji II Cement (resin-reinforced glass ionomer cement), in subgroup B with RelyX Unicem (self-adhesive resin cement), and in subgroup C with Metacem Refill (total-etch resin cement). Push-out bond strength (N) for each sample was measured using a universal testing machine, and the failure mode was assessed with a stereomicroscope at 30× magnification. The fiber post’s morphological structure was analyzed through scanning electron microscopy. Statistical analysis included one-way ANOVA followed by Tukey’s post hoc test in the case of significant differences between the groups. p-Values less than 0.05 were considered statistically significant. Results: This study found no statistically significant difference between using 17% EDTA and 2% chitosan as the final irrigant before post placement (p > 0.05). RelyX Unicem cement showed significant bonding strength when used with 2% chitosan in the coronal, middle, and apical thirds (p = 0.009, p = 0.02, p = 0.01, respectively). Conclusions: Chitosan at 2% can be considered a good alternative to 17% EDTA when used as a final irrigant for the post space. Full article

Objectives: This study was designed to assess the effectiveness of chitosan as a coupling agent for improving the tensile bond strength of fiber posts. Methods: A total of 91 single-rooted mandibular teeth were root canal-filled. Post spaces were created and categorized into seven groups: Group A (Control), Group B (Silane), Group C (Chitosan), Group D (37% Phosphoric acid + Silane), Group E (37% Phosphoric acid + Chitosan), Group F (10% Hydrogen Peroxide + Silane), and Group G (10% Hydrogen Peroxide + Chitosan). Posts were cemented and tensile bond strength was measured, while the morphological structure of the fiber posts was analyzed using Scanning Electron Microscopy. One-way (ANOVA) and Tukey’s multiple comparison tests were performed at a level of significance of 5%. The percentages of fracture patterns among the groups were compared. Results: 10% Hydrogen peroxide + Chitosan exhibited the significantly highest tensile bond strength (p < 0.001). Adhesive failures were more frequent in Groups A, B, C, and D, whereas cohesive failures within the resin cement were predominant in Groups E, F, and G. Conclusions: The protocol of using 10% hydrogen peroxide followed by a chitosan coupling agent significantly improved tensile bond strengths for glass fiber posts, which highlights the potential of using chitosan as a natural biopolymer and an alternative to synthetic coupling agents to develop more effective bonding strategies for dental restorations.

This study evaluated the effectiveness of atmospheric pressure plasma jet (APPJ) treatment on the surface characteristics and bond strength of zirconia and lithium disilicate ceramics for CAD-on restorations. A total of 70 cylindrical-shaped specimens of lithium disilicate and 70 disc-shaped specimens of Y-TZP zirconia were machined, thermally processed, surface-treated, and then resin-bonded. The specimens were grouped according to the following surface treatments: no surface treatment, sandblasting, plasma, sandblasting followed by plasma, sandblasting followed by universal adhesive, plasma followed by universal adhesive, and sandblasting and plasma treatment followed by universal adhesive. The treated surfaces were subjected to a wettability assessment via contact angle measurement and a topography assessment using scanning electron microscopy (SEM). The cemented assembly was subjected to shear bond strength testing with a universal testing machine, and the results were imported to SPSS 23.0 for statistical analysis. The results show that APPJ treatment induced a significantly low contact angle for both ceramics with no surface alteration upon scanning. Moreover, APPJ treatment produced a bonded assembly with a shear bond strength comparable to sandblasting. In conclusion, APPJ treatment should be considered an efficient surface treatment with a non-destructive nature that surpasses sandblasting with the provision of a high shear bond strength between CAD-on ceramics.

Background: Resin-bonded fixed dental prostheses (RBFDPs) have become an increasingly popular minimally invasive solution for replacing missing anterior teeth. However, their long-term success is influenced by factors such as bridge design and material selection. Methods: This systematic review and meta-analysis aimed to assess the impact of different bridge designs on the clinical performance and failure risks of anterior ceramic RBFDPs. A comprehensive search of electronic databases was conducted to identify clinical studies published in English up to January 2025. Nine studies, including randomized controlled trials, cohort studies, and clinical trials, met the inclusion criteria. Results: The analysis revealed that single-retainer RBFDPs demonstrated lower failure rates than two-retainer models (RR: 0.36, 95% CI: 0.17–0.75). Among failure types, fractures were significantly less common in cantilever designs compared to two-retainer designs (RR: 0.25, 95% CI: 0.09–0.73), while no significant differences were observed in debonding rates (OR: 0.40, 95% CI: 0.015–1.10). Conclusions: In terms of material selection, all-ceramic RBFDPs in cantilever designs exhibited significantly lower failure rates (RR: 0.12, 95% CI: 0.03–0.43), whereas metal-ceramic RBFDPs showed no significant difference in failure rates based on bridge design (RR: 0.56, 95% CI: 0.21–1.53). These findings suggest that all-ceramic cantilever RBFDPs may offer superior long-term outcomes, highlighting the importance of precise preparation and cementation protocols for clinical success.
