氧化锆修复体在牙科治疗中越来越受欢迎。氧化钇稳定的氧化锆(YSZ)需要烧结以用于临床应用,并且正在开发用于椅旁治疗的新型速度烧结方案。速烧YSZ的性能是否符合临床要求,然而,尚不清楚。因此,我们根据系统评价和荟萃分析(PRISMA)2020指南的首选报告项目,对速度烧结对牙科YSZ光学和机械性能的影响进行了系统评价和荟萃分析.使用PubMed进行了文献检索,Embase,和WebofScience数据库,用于2010年1月1日至2022年2月28日以英文发布的相关文章,中文,或日本人。经过全文评估和质量评估,选择了26篇文章。荟萃分析表明,速度烧结不会显着影响基于CIEDE2000的半透明参数,对比度,三点弯曲强度,双轴弯曲强度,或YSZ的断裂韧性(p<0.01)与常规烧结相比。然而,传统烧结YSZ的CIELab基半透明参数高于快速烧结YSZ。描述性分析表明,与常规烧结的YSZ相比,速度烧结不会影响YSZ的硬度。结果表明,快速烧结法适合制备用于牙科修复的YSZ。
Zirconia restorations are increasingly popular in dental treatment. Yttria-stabilized zirconia (YSZ) needs to be sintered for clinical applications and novel speed-sintering protocols are being developed for chairside treatments. Whether the properties of speed-sintered YSZ meet clinical requirements, however, remains unclear. Therefore, we conducted a systematic
review and meta-analysis on the influence of speed-sintering on the optical and mechanical properties of dental YSZ according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. A literature search was conducted using PubMed, Embase, and Web of Science databases for relevant articles published between January 1, 2010 and February 28, 2022 in English, Chinese, or Japanese. After full-text evaluation and quality assessment, 26 articles were selected. Meta-analysis revealed that speed-sintering does not significantly affect the CIEDE2000-based translucency parameter, contrast ratio, three-point flexural strength, biaxial flexural strength, or fracture toughness of YSZ (p < 0.01) compared to conventional sintering. However, the CIELab-based translucency parameter of conventionally sintered YSZ is higher than that of speed-sintered YSZ. The descriptive analysis indicated that speed-sintering does not affect the hardness of YSZ compared to that of conventionally sintered YSZ. The results indicate that speed-sintering is suitable for preparing YSZ for dental restorations.
