摘要

目的:评价软磨钴铬(Co-Cr)与其他构建方法/修复材料在牙齿/种植体支持修复中的边缘精度。材料与方法:定义PICO问题,并在6个电子数据库中进行系统检索。题目和摘要由两名独立审稿人收集和筛选。删除重复文章后,收集相关文章全文,提取所需信息和数据。评估偏倚风险,并使用STATA软件版本16对收集的数据进行荟萃分析。结果:共回顾了1914篇实验和临床论文,并选择了18项研究进行定性分析。meta分析纳入的16项研究显示,软磨Co-Cr与以下方法/材料之间没有显著的边际差距:硬磨Co-Cr (I2 = 92.9%, P = 0.86)、铸蜡(I2 = 90.9%, P = 0.42)、激光烧结Co-Cr (I2 = 93.3%, P = 0.46)和氧化锆(I2 = 0.00%, P = 0.47)。然而,与蜡铸模相比,软磨Co-Cr的边际精度明显更高(I2 = 93.1%, P < 0.001)。结论:软磨钴铬修复体的边缘间隙在临床可接受的范围内,对于所制备的种植基牙和牙齿,其准确性与其他可用的方法/材料相似。

Marginal Accuracy of CAD/CAM Frameworks Fabricated by Presintered Cobalt-Chromium Alloy: A Systematic Review and Meta-analysis.

Purpose: To evaluate the marginal accuracy of soft-milled cobalt-chromium (Co-Cr) compared to other construction methods/restorative materials in tooth/implant-supported restorations. Materials and Methods: PICO questions were defined, and a systematic search was conducted in six electronic databases. Titles and abstracts were collected and screened by two independent reviewers. After removing duplicate articles, the full texts of relevant articles were gathered, and the required information and data were extracted. Risk of bias was assessed and meta-analyses of the collected data were conducted using STATA software version 16. Results: A total of 1,914 experimental and clinical articles were reviewed, and 18 studies were selected for qualitative analysis. The 16 studies that were included in the meta-analysis showed no significant marginal gap differences between soft-milled Co-Cr and the following methods/materials: hard-milled Co-Cr (I2 = 92.9%, P = .86), casting wax (I2 = 90.9%, P = .42), laser-sintered Co-Cr (I2 = 93.3%, P = .46), and zirconia (I2 = 0.00%, P = .47). However, a significantly higher marginal accuracy of soft-milled Co-Cr was observed when compared to milled-wax casting (I2 = 93.1%, P < .001). Conclusion: The marginal gap of soft-milled Co-Cr restorations is within the acceptable clinical range and provides an accuracy similar to other available methods/materials for both the prepared implant abutment and tooth.

期刊介绍: Edited by Steven E. Eckert, DDS, MS ISSN (Print): 0882-2786 ISSN (Online): 1942-4434 This highly regarded, often-cited journal integrates clinical and scientific data to improve methods and results of oral and maxillofacial implant therapy. It presents pioneering research, technology, clinical applications, reviews of the literature, seminal studies, emerging technology, position papers, and consensus studies, as well as the many clinical and therapeutic innovations that ensue as a result of these efforts. The editorial board is composed of recognized opinion leaders in their respective areas of expertise and reflects the international reach of the journal. Under their leadership, JOMI maintains its strong scientific integrity while expanding its influence within the field of implant dentistry. JOMI’s popular regular feature "Thematic Abstract Review" presents a review of abstracts of recently published articles on a specific topical area of interest each issue.
