Table 3_Clinical performance of short implants vs. standard implants in edentulous patients. An umbrella review.docx

AimTo assess the clinical performance of short implants compared to standard-length implants in edentulous patients through an umbrella review.
Material and methodsA comprehensive search was conducted in databases such as PubMed, Cochrane Library, Scopus, SciELO, Google Scholar, ProQuest Dissertations and Theses, and OpenGrey, covering literature up to June 2025. Included studies were systematic reviews, with or without meta-analysis, that compared short implants with standard-length implants, with or without bone augmentation, reporting on implant survival, marginal bone loss, and biological or prosthetic complications. Reviews of a narrative nature, rapid reviews, clinical trials, observational or experimental studies, case reports, editorials, letters, protocols, and posters were excluded. The methodological quality of the reviews was assessed using the AMSTAR-2 tool.
ResultsFrom an initial retrieval of 790 records, 60 systematic reviews met the inclusion criteria. The data showed no significant differences in survival rates, implant failure, or prosthetic complications between short and standard implants. However, short implants showed less marginal bone loss and fewer biological complications.
ConclusionBased on high-confidence systematic reviews, short implants provide comparable clinical outcomes to standard-length implants and are a viable, less invasive alternative for patients with reduced vertical bone height.

本研究旨在通过伞状综述（Umbrella Review），评估无牙颌患者中短种植体与标准长度种植体的临床应用效果。
材料与方法：本研究在PubMed、Cochrane Library、Scopus、SciELO、Google Scholar、ProQuest Dissertations and Theses、OpenGrey等数据库开展全面检索，检索覆盖截至2025年6月的相关文献。纳入研究为含或不含荟萃分析的系统综述，需比较短种植体与标准长度种植体（伴或不伴骨增量术），并报告种植体留存率、边缘骨丢失量以及生物学或修复并发症。排除叙事性综述、快速综述、临床试验、观察性或实验性研究、病例报告、社论、信函、研究方案及海报类文献。采用AMSTAR-2工具对纳入综述的方法学质量进行评估。
结果：初始检索共获取790条文献记录，最终有60篇系统综述符合纳入标准。数据显示，短种植体与标准种植体在留存率、种植体失败率或修复并发症方面无显著差异；但短种植体的边缘骨丢失量更少，生物学并发症发生率更低。
结论：基于高质量系统综述，短种植体的临床疗效与标准长度种植体相当，可作为垂直骨高度不足患者的一种可行且侵入性更低的替代方案。
