“…In vitro evaluations have reported mean gap values between 11 and 129.2 μm for the marginal and 48 to 100.9 μm for the internal surfaces of metal‐ceramic crowns on implant abutments . Freire et al evaluated the marginal fit of CAD/CAM monolithic ceramic and metal‐ceramic crowns and reported that monolithic lithium disilicate ceramic demonstrated the best marginal fit (27.95 μm), and that there was no significant difference between metal‐ceramic (57.42, 19.28 μm) and monolithic zirconia (58.05 μm).…”

Paşalı et al evaluated the marginal fit of implant‐supported metal copings fabricated by casting, milling, and milling‐sintering methods. They reported a mean marginal gap value of 92 μm for casting, 81 μm for milling, and 99 μm for milling‐sintering.…”

“…Different methods have been used to evaluate the marginal and internal accuracy of fit. The silicone replica method is one the most common methods used to measure the marginal fit . The advantages of this method are that it saves time and money, and the fit of the restorations can be measured without any damage to the restoration.…”

“…Accuracy of fit between abutment and restoration plays a key role in considering the long‐term success of implant‐supported restorations . Insufficient fit can cause bacterial leakage and plaque accumulation, which may cause peri‐implant mucositis and peri‐implantitis …”

Purpose To compare the marginal and internal fit of cobalt‐chromium (Co‐Cr) alloy copings fabricated by with lost wax technique (LW), computer‐aided design and computer‐aided manufacturing (CAD/CAM), and direct metal laser sintering (DMLS). Materials and Methods Thirty‐six tissue level, straight titanium abutments were screwed onto implant replicas. All specimens were embedded in acrylic resin and randomly divided into 3 subgroups according to the fabrication of metal coping: LW, CAD/CAM, and DMLS. In total, 36 (n = 12/group) Co‐Cr implant‐supported metal copings were prepared. Marginal, intermarginal, axial, and occlusal fits of each coping were measured using the silicone replica technique. The data were evaluated statistically using one‐way ANOVA and Bonferioni post‐hoc test (α = 0.05). Results The CAD/CAM group showed significantly lower marginal fit than the LW group and DMLS groups (p < 0.001). The marginal fit of the LW group was not significantly different from the DMLS group (p = 0.721). No significant difference found among the fabrication methods in terms of intermarginal fit (p = 0.913). The CAD/CAM group showed lower axial fit than the LW group (p = 0.026), but there was no statistical difference between the DMLS group and the LW (p = 0.999) and CAD/CAM groups (p = 0.247). No significant differences found among the fabrication methods in terms of occlusal fit (p = 0.158). Conclusions The LW and DMLS groups showed better marginal fit compared to the CAD/CAM group; however, the CAD/CAM group was better than the LW group in terms of axial fit. All fabrication methods demonstrated similar intermarginal and occlusal fit.

“…Measuring tools and skills have improved considerably, and marginal gaps have thus been measured more precisely. Notwithstanding, investigations on the marginal fit of SM-based restorations appear to have not only a bias in the selection of conventional materials, but also a tendency to show superiority in modern development [52][53][54][55][56].…”

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.
