“…Figure 2 shows the results of the quality assessment using QUADAS-2. Of the 21 articles, 10 exhibited a low risk of bias [21,24,[28][29][30]32,34,[36][37][38], and 11 articles showed some level of unclear risk of bias [22,23,[25][26][27]31,33,35,[39][40][41]. All the included studies had a clearly stated purpose and included a control group for the evaluation of the marginal fit.…”

“…With respect to the index and reference test domains, most studies provided adequate detailed information about the fabrication procedures, parameters, and devices. However, several studies did not explicitly provide the product name of the alloy [26,27,31,32,41] and the setting of cementation space [22,23,26,33,40]. With respect to the flow and timing domain, all the studies clearly reported the measurement methods, positions, and the number of measurement points per specimen.…”

Reliability of Metal 3D Printing with Respect to the Marginal Fit of Fixed Dental Prostheses: A Systematic Review and Meta-Analysis

et al. 2020

Three-dimensional (3D) printing technologies have been widely used to manufacture crowns and frameworks for fixed dental prostheses. This systematic review and meta-analysis aimed to assess the reliability of the marginal fit of 3D-printed cobalt-chromium-based fixed dental prostheses in comparison to conventional casting methods. Articles published until 25 June 2020, reporting the marginal fit of fixed prostheses fabricated with metal 3D printing, were searched using electronic literature databases. After the screening and quality assessment, 21 eligible peer-reviewed articles were selected. Meta-analysis revealed that the marginal gap of the prostheses manufactured using 3D printing was significantly smaller compared to that manufactured using casting methods (standard mean difference (95% CI): −0.92 (−1.45, −0.38); Z = −3.37; p = 0.0008). The estimated difference between the single and multi-unit types did not differ significantly (p = 0.3573). In the subgroup analysis for the measurement methods, the tendency of marginal discrepancy between the 3D printing and casting groups was significantly different between articles that used direct observation and those that used the silicone replica technique (p < 0.001). Metal 3D printing technologies appear reliable as an alternative to casting methods in terms of the fit of the fixed dental prostheses. In order to analyze the factors influencing manufacturing and confirm the results of this review, further controlled laboratory and clinical studies are required.

“…Some research even suggests that AM results in a higher degree of precision and increased fitting accuracy [68]. Moreover, the majority of studies point out that SLS-manufactured dental objects provide better vertical marginal fit parameters than traditional fabrication processes [14, [77][78][79][80][81][82]. These superior properties appear independent of anatomical features since studies on molar and premolar crowns did not find any significant differences in vertical marginal fit.…”

The objective of this review was to collect information on available additive manufacturing technologies used for the fabrication of either single crowns or fixed-dental prosthesis (FDP) with a focus on the chemistry, surface characteristics and interaction between frameworks and veneering ceramics. Original scientific papers in MEDLINE (PubMed), Embase, Scopus databases, published between 01 January 1996 and 30 June 2020 were included in this review. The following MeSH terms, search terms and their combinations were used: 'in vitro', 'crowns', 'denture, partial, fixed', 'dentistry', 'fixed dental prosthesis', 'FDP', 'bridges', 'additive manufacturing', 'alloys', 'surface roughness', 'adhesion'. Two reviewers performed screening and analysed the data. Only the studies that reported on chemistry, surface characteristics and ceramic adhesion for FDPs were included. The selection process resulted in the final sample of 91 journal articles. In total, 16 articles were identified related to chemistry of alloys used in additive manufacturing: 1 on surface characteristics, and 9 on adhesion of veneering ceramics to alloys. In addition, review articles, books, patents and manufacturersinformation were retrieved. Accordingly, it was noted that current additive technologies use mainly Co-Cr or titanium alloys but the production of the starting material presently lacks sufficient standardization and regulations. For these alloys, rougher surface microstructure (3.2 ± 0.4 mm) than for cast alloys (2.3 ± 0.6 mm) was reported which may have clinical implications in implant dentistry. There is some evidence that surface roughness contributes to increased bond strength of veneering ceramic to metal frameworks ranging between 24 ± 10 and 54 ± 14 MPa but the detailed underlying metal-ceramic adhesion mechanism remains to be elucidated.

“…AM utilizes plastic or wax materials, producing burnout patterns that are subsequently changed to metal restorations by casting, or to all-ceramic restorations by the heat-pressing of lithium disilicate glass. Recently, large-scale metal frameworks for fixed implant-supported prostheses and removable partial dentures have been directly printed three-dimensionally, using cobalt-chromium or titanium alloys and a technology that selectively melts metal powder with lasers (selective laser melting) [9][10][11]. However, the clinical application of AM has not yet been realized for ceramic restorations.…”

Computer-aided design and manufacturing technology has been closely associated with implant-supported restoration. The digital system employed for prosthodontic restorations comprises data acquisition, processing, and manufacturing using subtractive or additive methods. As digital implantology has developed, optical scanning, computer-based digital algorithms, fabricating techniques, and numerical control skills have all rapidly improved in terms of their accuracy, which has resulted in the development of new ceramic materials with advanced esthetics and durability for clinical application. This study reviews the application of digital technology in implant-supported dental restoration and explores two globally utilized ceramic restorative materials: Yttria-stabilized tetragonal zirconia polycrystalline and lithium disilicate glass ceramics.
