Journal of Prosthodontic Research
Journal of Prosthodontic Research (JPR) is published 4 times annually, in January, April, July, and October, under the supervision of the JPR Editorial Committee of the Japan Prosthodontic Society, which selects all materials submitted for publication.

JPR originated as the official journal of the Japan Prosthodontic Society. It has recently developed a long-term plan to become the most prestigious Asian journal of dental research covering all aspects of oral and occlusal rehabilitation, fixed/removable prosthodontics, oral implantology, and applied oral biology and physiology. The Journal will cover all diagnostic and clinical management aspects necessary to reestablish subjective and objective harmonious oral aesthetics and function.

The most-targeted topics:
1)     Clinical Epidemiology and Prosthodontics
2)     Fixed/Removable Prosthodontics
3)     Oral Implantology
4)     Geriatric Dentistry
5)     Dental Materials / Adhesive Dentistry / Aesthetic Dentistry
6)     Digital Dentistry
7)     Oral Physiology and Biomechanics (Masticating and Swallowing Function, Parafunction, e.g., bruxism)
8)     Orofacial Pain and Temporomandibular Disorders (TMDs)
9)     Maxillofacial Prosthodontics and Dysphagia Rehabilitation
10)   Prosthodontics-Related Biosciences (Regenerative Medicine, Bone Biology, Mechanobiology, Microbiology/Immunology)

Prosthodontic treatment may become necessary as a result of developmental or acquired disturbances in the orofacial region, orofacial trauma, or a variety of dental and oral diseases and orofacial pain conditions.

The scientific content of the Journal, therefore, strives to reflect the best of evidence-based clinical dentistry. Modern clinical management should be based on solid scientific evidence, gathered about diagnostic procedures and the properties and efficacy of the chosen intervention. The content of the Journal also includes documentation of the possible side-effects of rehabilitation, as well as prognostic perspectives of the treatment modalities chosen.

The Journal focuses on presenting original research findings and original technical appraisals, as also critical reviews and relevant case reports, and stimulating commentaries and professional debates in the Letters to the Editor column.

Accuracy and practicality of intraoral scanner in dentistry: A literature review Read more
Editor’s picks

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.

Application of titanium and titanium alloys to fixed dental prostheses Read more
Editor’s picks

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.

Current status of zirconia implants in dentistry: preclinical tests Read more
Editor’s picks

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.

Substrate masking ability of bilayer and monolithic ceramics used for complete crowns and the effect of association with an opaque resin-based luting agent Read more
Editor’s picks

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.

Tongue function is important for masticatory performance in the healthy elderly: a cross-sectional survey of community-dwelling elderly Read more
Editor’s picks

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.
