Topical Collection Information

Dear Colleagues,

In the last decade, the search for innovative fabrication technologies and novel restorative materials has allowed digital workflows to become increasingly widespread in dentistry, widening treatment scenarios and clinical protocols, particularly in prosthodontics and restorative dentistry.

The introduction of optical impressions and intraoral scanners, as well as the implementation of production lines with CAD/CAM manufacturing and 3D printing, has exploited the operative advantages of new classes of dental ceramics and innovative metal-free restorative materials, significantly improving the biocompatibility, mechanical characteristic, and optical properties of tooth-like prostheses and reconstructions. Moreover, the optimal structural resistance of novel ceramic materials has enabled a reduction in the thickness of restorations, saving, in turn, a significant amount of dental tissue, in accordance with the principles of minimal intervention dentistry. 

Conventional dental ceramics have been compared to polycrystalline cores (such as conventional and translucent zirconia) and high-strength glass ceramics (such as lithium disilicate). Nonetheless, innovative restorative materials have been developed to further improve mechanical and esthetic properties, offer reliable accuracy and precision, and reduce fabrication and chairside time. Consequently, innovative ceramic materials have been recently introduced in the dental market, such as hybrid ceramics and zirconia-reinforced lithium silicates (ZLS).

The physical–chemical profile of such novel restorative materials allows for the reduction in restorative thicknesses, ensuring, at the same time, impressive esthetic and clinical performances; these improvements have dramatically widened the range of clinical options in tooth- and implant-supported prosthodontics.

Clinical operators can profit from these improved ceramics, particularly in the digital workflow, rendering operative steps standardized and easier, thus improving, in turn, patients’ comfort and restorative experiences.

Objective: The purpose of this study was to evaluate the cervical marginal fit of porcelain laminate veneer (PLV) restorations made from two different types of CAD/CAM ceramic laminates: CEREC C PC and E.max (LD). Materials and Methods: This in-vitro experiment used a total of 32 human maxillary first premolars that were clean and free of any cracks or caries, extracted for orthodontic purposes. The samples were divided in a random way into two study groups: A and B (n = 16). Each sample was mounted on a dental surveyor and a silicon impression was made to create a silicone index for each tooth in both groups. Standardized preparation was carried out for all the samples by using preparation bur kit for the ceramic veneer system. Subsequently, digital impressions were made for all the samples by using Trios 3 shape intraoral camera (Sirona Dental Systems). The design of veneer restorations was made using Sirona inLab CAD SW 16.1 with CEREC inLab MC XL (Dentsply, Sirona Dental Systems, Bensheim, Germany). The veneer restorations were cemented using 3M RelyX veneer resin cement (3M ESPE, Seefeld, Germany) and the samples kept in distilled water for two weeks at 37 °C. All the specimens were subjected to thermocycling in a water bath with temperature varying between 5 °C and 55 °C for 500 cycles. The cervical marginal fit of veneers was evaluated by a digital microscope after sectioning the embedded teeth in acrylic resin. Results: The lowest mean of cervical marginal gap was recorded for Group A (91.59431 ± 1.626069) which was restored with CEREC CAD/CAM veneers, while the highest mean value of the gap was recorded for Group B (106.48863 ± 2.506684) which was restored with IPS E.max CAD. The t-test showed that the type of porcelain veneer restoration had a highly significant effect on the cervical marginal fit (p ≤ 0.01). Conclusions: CEREC CAD/CAM veneers showed smaller cervical marginal gaps, indicating a better fit compared to the IPS E.max CAD. Full article
