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 continued to grow as a leading journal of prosthodontic 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.

Impact of restorative materials on biomechanical behavior of endocrown and post-core restorations: A 3-dimensional finite element analysis Read more
Editor's pick

This study presented a novel three-dimensional finite element analysis of the biomechanical behavior of various CAD/CAM and conventional materials in the endocrown and post-core restorations of structurally compromised teeth lacking a ferrule. The results demonstrated that lithium disilicate and PEEK optimized stress distribution depending on the tooth’s location (anterior or posterior), whereas gold post-core systems provide superior root stress mitigation. Notably, PEEK exhibited a higher risk of cement failure despite the lower internal stress levels. These findings offer evidence-based insights to guide clinicians in material selection, highlighting the importance of aligning mechanical performance with clinical demands for long-term restorative success.

Metal allergy as a persistent factor for psoriasis Read more
Editor's pick

In patients with suspected dental metal allergies, psoriasis symptoms improved after removal of the metal from the oral prosthesis. However, the relationship and mechanism of the metal removal effect and improvement of psoriasis symptoms in patients with metal allergies remain unknown. This study investigated the relationship between metal allergies and psoriasis using an animal model. The results suggested that nickel allergy may prolong psoriasis via IL-17 production in the submandibular lymph nodes and spleen.

Association between denture restoration for tooth loss and cognitive impairment: A systematic review and meta-analysis Read more
Editor's pick

The association between oral health and cognitive function has been attracting attention in geriatric research. This review synthesized evidence from observational studies and offered valuable insights into the  potential preventive role of denture restoration in cognitive impairment. Although  causality cannot be established, timely denture rehabilitation may help attenuate the adverse cognitive impact of tooth loss. These results underscore the broader relevance of prosthodontic care for restoring oral function and supporting cognitive health, particularly in aging populations.

Dental human enamel wear caused by ceramic antagonists: A systematic review and network meta-analysis Read more
Editor's pick

Enamel wear is a critical concern in prosthetic dentistry and affects occlusal stability, aesthetics, and long-term function. This systematic review compared metal-ceramic, glazed zirconia, and polished zirconia crowns to determine their effects against enamel surfaces. The findings demonstrated that polished zirconia crowns produced the least enamel wear among the tested materials, underscoring their clinical advantage over metal-ceramic and glazed zirconia. This study provides valuable evidence to guide clinicians in material selection, particularly for patients at high risk of enamel wear.

Efficacy of initial conservative treatment options for temporomandibular disorders: A network meta-analysis of randomized clinical trials Read more
Editor's pick

The efficacy of conservative treatment in the early stages of temporomandibular disorders (TMD) remains unclear. Among the treatment options implemented within three months, stabilization splinting, self-exercise, and low-level laser therapy improved pain and maximal mouth opening during the early stages of pain-related TMD.
