The most cited review article in the Journal of Prosthodontic Research is about the accuracy and practicality of intraoral scanner in dentistry; from the articles searched by keywords about intraoral scanners. The authors investigated the effect of accuracy and reproducibility of standard triangulated language data in relation to: the scanning range, verification method for reproducibility, comparison of intraoral scanner and desktop scanner, and patient satisfaction; in comparison with conventional impression techniques. Since this article also shows a table about the range accuracy of various intraoral scanners, it is important for dentists using intraoral scanners.
In June 2020, prosthetic treatments with full-cast crowns made of titanium in molar teeth were included in Japanese dental health insurance. This article reviewed the properties of titanium and titanium alloys and their castings, as well as evidence regarding the fitness of the crown to the abutment and clinical performance from clinical studies. Recently, the price of Ag–Pd–Au alloys used for fixed dental prostheses has rapidly increased in Japan. Thus, the application of titanium and titanium alloys to full-cast crowns has significant benefits, as titanium and titanium alloys are low-cost metals. This review is recommended for clinicians to understand the clinical applications of titanium and titanium alloys to fixed dental prostheses.
Zirconia implants are a potential alternative to titanium implants because they: avoid discoloration of the gingiva, metal hypersensitivity, and degradation of resistance to corrosion. However, the knowledge regarding the basic background of zirconia implants is poorly understood. This review article summarizes the basic background of zirconia implants and the implant-restoration complex in terms of preclinical outcomes, namely material properties, implant design, osseointegration capacity, soft tissue integration, and restorative options. An overview of available zirconia implants and the implant-restoration complex would enhance the knowledge of clinicians and provide them with useful information regarding their applicability.
For metal-free restorations, highly translucent ceramic materials show excellent color matching with the natural tooth substructure, and it is possible to reproduce brilliant aesthetics naturally. However, the final crown shade is strongly affected by the abutment tooth color. This study aimed to evaluate the substrate masking ability of different ceramic systems used for complete crowns on different abutment colors (A1, A3.5, C4, copper, and silver), and assess the influence of their association with an opaque resin-based luting agent. The results showed that the ceramic systems and the white-opaque resin-based luting agent presented a significant effect on the substrate masking ability.
Maintaining good masticatory performance is essential for achieving good nutritional balance. In addition, tongue function plays an important role in performing a good masticatory function. To date, many studies have mentioned the relationship between the number of teeth, occlusal support, and masticatory performance. This article newly clarifies the importance of tongue function as a factor related to masticatory performance after eliminating the influence of the number of teeth. When developing research on masticatory function, the findings obtained in this research will provide further depth to the background and discussion.
