| 摘 要： | 目的:回顾分析评价CAD/CAM氧化锆全瓷冠桥的修复效果.方法:为267位患者制做CAD/CAM氧化锆全瓷冠或桥681件,随访了205例患者的562件全瓷冠桥,随访时间2-6年.对修复体的崩瓷、全瓷冠的颜色与修复体的边缘密合度进行评价.结果:CAD/CAM氧化锆全瓷冠的崩瓷率3.31%,与修复体部位有明显相关性(P＜0.01),不同技术员完成的CAD/C氧化锆全瓷冠的颜色效果有明显不同(P＜0.001),不同颜色预备体的修复体后颜色效果没有明显差异(P＞0.05),CAD/CAM全瓷冠颜色达到好以上90.8%,CAD/CAM全瓷修复体的边缘密合度达到好的99.2%,长桥边缘密合度欠佳,修复体松动脱落0.35%,随访期间没有发现CAD/CAM全瓷修复体基底冠或桥支架折断.结论:CAD/CAM全瓷冠颜色接近天然牙,特别是预备体变色时是115床旨选的美学修复体,CAD/CAM全瓷冠边缘密合度好,整体崩瓷率可接受,但长桥边缘密合度需进一步提高,且磨牙的崩瓷率须进一步研究降低.

| Abstract: | Objective: To evaluate the clinical performance of CAD/CAM zirconia all-ceramic crowns and fixed partial dentures(FPDs).Methods: 681 all-ceramic crowns or FPDs were fabricated for 267 patients.562 restorations of 205 patients were clinically followed for 2-6 years.Recalls were made 3 months after cementation.Porcelain fracture performance was compared between restorations in anterior and premolar and molar.Using modified US Public Health Service criteria,judgments were made on marginal integrity and shade a... |
