这项前瞻性临床裂口研究的目的是研究压制和计算机辅助设计/计算机辅助制造（CAD/CAM）全陶瓷部分覆盖修复体（pcr）的长期性能。25例患者采用40枚二硅酸锂加压pcr （IPS e.m ax- press, Ivoclar Vivadent）和40枚白石增强玻璃陶瓷CAD/CAM pcr （ProCAD, Ivoclar Vivadent）进行修复。所有的修复体都放置在重要的第一或第二磨牙上。压制pcr的7年Kaplan-Meier生存率为100%，CAD/CAM pcr为97%。随着时间的推移，这两个系统在所有修改后的美国公共卫生服务标准中都表现出明显的恶化。表面粗糙度增加和颜色匹配受损明显更普遍与压制pcr。根据7年的数据，这两种全陶瓷系统都可以被认为是后路pcr可靠的治疗选择。[J]中华口腔医学杂志，2013;26(6):591 - 591。doi: 10.11607 / ijp.3043
The aim of this prospective clinical split-mouth study was to investigate the long-term performance of pressed and computer-aided design/computer-assisted manufacture (CAD/CAM) all-ceramic partial-coverage restorations (PCRs). Twenty-five patients were restored with 40 lithium disilicate pressed PCRs (IPS e. max-Press, Ivoclar Vivadent) and 40 leucite-reinforced glass-ceramic CAD/CAM PCRs (ProCAD, Ivoclar Vivadent). All restorations were placed in vital first or second molars. The 7-year Kaplan-Meier survival rate was 100% for pressed PCRs and 97% for CAD/CAM PCRs. Both systems showed significant deterioration over time in all modified United States Public Health Service criteria. Increased surface roughness and impaired color match were significantly more prevalent with pressed PCRs. Based on the 7-year data, both all-ceramic systems can be considered reliable treatment options for posterior PCRs. Int J Prosthodont 2013;26:21-25. doi: 10.11607/ijp.3043
