    Dental human enamel wear caused by ceramic antagonists: A systematic review and network meta-analysis もっと読む
    編集者のコメント

    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.

    A finite element study on the risk of bone loss around posterior short implants in an atrophic mandible もっと読む
    編集者のコメント

    This study investigated biomechanical factors affecting bone resorption around short dental implants in atrophic mandibles. Using finite element analysis, the authors found that increasing the implant diameter and optimizing the occlusal contact areas lowered the risk of bone loss, even with a high crown-to-implant ratio. Short implants with wider diameters or increased occlusal contacts demonstrated performance comparable to that of standard-length implants in non-atrophic mandibles. These findings indicate that short and wide implants are safer options for patients with atrophic mandibles, as they reduce the risk of nerve injury while ensuring implant success. This study offers valuable insights for enhancing dental implant procedures.

    Marginal bone loss in dental implants: A literature review of risk factors and treatment strategies for prevention もっと読む
    編集者のコメント

    This narrative review focuses on marginal bone loss (MBL) after dental implant placement and its association with peri-implantitis. Although MBL does not always indicate peri-implantitis, early MBL may be a predictor of its development. This review summarizes the current literature and highlights the biological, material, and technical factors that influence MBL risk. The key recommendations include controlling smoking and hemoglobin A1c levels, selecting appropriate implant systems, ensuring sufficient soft tissue management, and using connected concave abutments. This review emphasizes that a multifactorial approach can significantly reduce MBL and improve the long-term success of dental implants.

    Effect of soft denture liners on complete denture treatments: A systematic review もっと読む
    編集者のコメント

    This study systematically reviewed clinical studies to examine the effectiveness of soft denture relining (SDR) materials used for removable dentures and found that SDR often provides beneficial outcomes such as pain reduction and recovery of chewing ability with dentures. However, caution should be exercised regarding their use, owing to insufficient functional duration and the possibility of microbial contamination during long-term use. This review highlights the clinical significance and limitations of SDR in maintaining the quality of life of individuals using removable dentures.

    Dental prosthesis use moderates association between tooth loss and risk of depressive symptoms in older adults with severe tooth loss: The JAGES cohort trial もっと読む
    編集者のコメント

    This article provides a compelling investigation into the moderating role of dental prostheses in the risk of depressive symptoms developing due to tooth loss among older adults. Utilizing data from the Japan Gerontological Evaluation Study, the authors conducted a robust cohort analysis of over 50,000 participants, identifying that those with severe tooth loss and no prostheses experienced the highest risk of depressive symptoms. The use of dental prostheses may mitigate this risk of depression linked to severe tooth loss. These findings emphasize the importance of dental interventions in mental health strategies for older adults.

    Effect of filler contents on the bond strength of CAD/CAM resin crowns: New resin primer versus conventional silane agents もっと読む
    編集者のコメント

    A groundbreaking study has emerged with the potential to revolutionize dental treatments. The latest research has focused on the adhesive strength of resin composite crowns fabricated using CAD/CAM technology. This study compared the efficacy of a novel resin primer containing methyl methacrylate (MMA) with those of conventional silane agents. The results showed that treatment with MMA-containing primers improved the adhesion between the resin composite blocks and resin cement. In addition, the MMA-containing primer formed a 5-10 μm layer at the interface, exhibiting a distinct adhesion mechanism via silane treatment. These findings provide major insights into the development of novel bonding protocols for dental care. Expectations are high for future advancements in the theory of adhesion mechanisms.

    Ceramic partial laminate veneers in anterior teeth: A literature review もっと読む
    編集者のコメント

    This literature review explored small ceramic restorations adhesively luted onto unprepared anterior teeth, also known as partial laminate veneers, fabricated from traditional ceramic and/or resin composite. From an electronic search, laboratory studies have suggested promising mechanical and optical performances for partial laminate veneers, and clinical reports have highlighted the large variability in material selection and application protocols. Overall, the review suggests comparable performance to traditional veneers but also indicates low-quality evidence for ceramic partial laminate veneers, thus emphasizing the need for further clinical studies with extended follow-up periods to confirm their effectiveness.

    Fabrication of milled removable partial dentures using a custom plate with prefabricated artificial teeth もっと読む
    編集者のコメント

    The fabrication of removable partial dentures (RPDs) through fully digital procedures remains a challenge. In this study, the authors developed a novel CAD/CAM method for manufacturing a patient-specific RPD in a single piece, using a custom plate. This method, which does not use a gypsum model to combine RPD components, metal framework, denture base, and artificial denture teeth, offers an advantage in the efficiency and accuracy of RPD fabrication over conventional methods. The development of this fully digital RPDs fabrication approach presented in this report will significantly impact prosthodontic clinics worldwide, especially in the context of an increasing aging population.
