不同粘接剂间隙对CAD/CAM嵌体边缘适应性的影响
Influence of different cement spaces on marginal adaptation of CAD/CAM inlay
摘要
Abstract
Objective To explore the influence of different cement spaces on the marginal adaptation of CAD/CAM zirconia inlay. Methods 30 teeth extracted for orthodontic purpose were selected and divided into 3 groups (Group A 10μm, Group B 30μm, Group C 50μm). The marginal spaces of inlays were recorded by the light-body Silicone im-pression material, and measured by microscope. The data were analyzed by SPSS 13.0. Results All the inlays fitted very well and all the marginal spaces were less than 120 μm. The shoulder of Group A was statistically lower than Group B and Group C (P<0.05). The axial surface of Group B was statistically lower than Group C (P<0.05). Conclu-sion CEREC zirconia inlay is satisfactory when the cement space is between 10-50μm.关键词
