Abstract

Purpose: This scoping review aimed to identify and discuss the recyclability of dental zirconia residuals along with the factors influencing the properties of dental recycled zirconia.

Study selection: In vitro studies written in both English and Chinese that evaluated the recyclability of dental zirconia residue were selected. A literature search was conducted in Medline, PubMed, Web of Science, and Cochrane Library databases with no restrictions on the publication year.

Results: Sixteen studies were included in this review. Residual dental zirconia can be recycled. Cold isostatic pressing improved the density of recycled zirconia compared with uniaxial pressing. Recycled zirconia powder with fine particles enhanced the performance of recycled zirconia compared with coarse particles. A presintering temperature of 950 to 1100°C was suitable for preparing recycled zirconia presintered bodies. Recycled zirconia may require a higher sintering temperature (≥1500°C) compared with commercially available zirconia. Additionally, recycled zirconia powder can enhance the properties of polymethylmethacrylate as a reinforcing filler and can be combined with alumina powder to obtain an alumina/zirconia composite material.

Conclusions: Despite a limited body of literature, the recycling and reutilization of dental zirconia residuals are feasible and reliable, and can reduce economic and environmental losses. Nevertheless, several factors influence the recycling effect, including the particle size, molding techniques, and sintering parameters. In addition, recycled zirconia powder can act as a reinforcing filler, potentially enhancing the mechanical properties of other materials. To realize commercially viable recycled zirconia materials, further studies are essential to comprehensively explore and understand their recycling performance.

氧化锆牙科材料回收利用的当前前景：范围审查

目的：本综述旨在确定和讨论牙科氧化锆残渣的可回收性以及影响牙科回收氧化锆性能的因素：研究选择：选择评估牙科氧化锆残渣可回收性的中英文体外研究。在 Medline、PubMed、Web of Science 和 Cochrane Library 等数据库中进行文献检索，不限制发表年份：本综述共纳入 16 项研究。残留的牙科氧化锆可以回收利用。与单轴压制相比，冷等静压可提高再生氧化锆的密度。与粗颗粒相比，细颗粒的再生氧化锆粉提高了再生氧化锆的性能。950 至 1100°C 的预烧结温度适合制备再生氧化锆预烧结体。与市售氧化锆相比，再生氧化锆可能需要更高的烧结温度（≥1500°C）。此外，回收氧化锆粉末可增强聚甲基丙烯酸甲酯作为增强填料的性能，并可与氧化铝粉末结合，获得氧化铝/氧化锆复合材料：尽管文献数量有限，但牙科氧化锆残渣的回收和再利用是可行且可靠的，可以减少经济和环境损失。然而，有几个因素会影响回收效果，包括粒度、成型技术和烧结参数。此外，回收的氧化锆粉末还可以作为增强填料，增强其他材料的机械性能。要实现商业上可行的再生氧化锆材料，必须开展进一步研究，以全面探索和了解其再生性能。

期刊介绍： Journal of Prosthodontic Research is published 4 times annually, in January, April, July, and October, under supervision by the Editorial Board of Japan Prosthodontic Society, which selects all materials submitted for publication. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. It has recently developed a long-range plan to become the most prestigious Asian journal of dental research regarding 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) Prosthodontics-Related Biosciences (Regenerative Medicine, Bone Biology, Mechanobiology, Microbiology/Immunology) 5) Oral Physiology and Biomechanics (Masticating and Swallowing Function, Parafunction, e.g., bruxism) 6) Orofacial Pain and Temporomandibular Disorders (TMDs) 7) Adhesive Dentistry / Dental Materials / Aesthetic Dentistry 8) Maxillofacial Prosthodontics and Dysphagia Rehabilitation 9) Digital Dentistry Prosthodontic treatment may become necessary as a result of developmental or acquired disturbances in the orofacial region, of orofacial trauma, or of a variety of dental and oral diseases and orofacial pain conditions. Reviews, Original articles, technical procedure and case reports can be submitted. Letters to the Editor commenting on papers or any aspect of Journal of Prosthodontic Research are welcomed.
