| 摘 要： | 目的:比较临床常用3种全瓷系统(Kavo Everest、IPS e.max、In-Ceram alumina)冠的边缘适合性,为临床应用提供理论依据。方法:选取1颗无龋的离体前磨牙行牙体预备,其中牙合面预备2mm,颈部凹槽肩台,宽度为0.8mm,牙合聚合度为6°。双重印模法取模,每种系统分别制作10个冠修复体。然后采用双色硅橡胶印模法复制间隙模型,应用光学显微镜采集间隙图像及使用Auto CAD2006软件对其水平边缘间隙、垂直边缘间隙和绝对边缘间隙进行测量,将所得数据使用SPSS13.0软件包进行单因素方差分析。结果:3种全瓷系统制作的上颌前磨牙冠的水平边缘间隙的平均值在41.1～44.9μm,垂直边缘间隙的平均值在51.4～71.7μm,绝对边缘间隙的平均值在66.2～85.1μm。结论:本研究中,3种全瓷系统冠的绝对边缘间隙、垂直边缘间隙和水平边缘间隙均在临床可接受范围;然而,与In-Ceramalumina系统相比,IPS e.max和Kavo Everest系统制作的全瓷冠显示出较好的边缘适合性。 |

| Abstract: | PURPOSE: This study was to compare the marginal adaptation of single crown made of 3 different all-ceramic systems(IPS e.max,In-Ceram alumina,Kavo Everest) in vitro using a light-body silicone supported by a heavy-body silicone material.METHODS: The crowns were made for 1 extracted maxillary premolar prepared with a 0.8-mm chamfer margin and 6-degree tapered walls by milling.Ten crowns per system were fabricated.The horizontal marginal discrepancies,vertical marginal discrepancies and absolute marginal disc... |
