Ceramage聚合瓷和IPS e.max Press材料磨损实验
In vitro study of wear of Ceramage and IPS e.max Press
摘要
Abstract
Objective To compare the wear of Ceramage and IPS e.max Press offering foundation for nonmetallic materials selection in clinical. Methods 20 class Ⅰ cavities were prepared in the approximal flattened sides of the extracted human maxillary first molars. The cavities were divided into 2 groups randomly, and then restored with Ceramage or IPS e.max Press. Inlays were prepared according to the manufactures' instructions with indirect methods and cemented with Varolink N. The non-wear extracted maxillary third molars were used as antagonistic enamel cusps after standardized prepared.After the self-made wear-testing device concluded 200,000 cycles under a load of 20 N,the wear depth of specimens and antagonistic enamel cusps was assessed by Kavo PREP assistant. Results The wear in Ceramage group was(298.30±40.02)μm,while the wear of normal enamel was(206.60±49.17)μm.The wear in IPS e.max Press group was (212.90±61.21) μm, while the wear of normal enamel was (217.00±25.10) μm. The wear of IPS e.max Press inlays was higher than Ceramage inlays (P<0.05). Ceramage inlays showed higher wear than normal enamel (P<0.05), while IPS e.max Press inlays was not statistically different from the normal enamel (P>0.05). Conclusions Ceramage has more wear than IPS e.max Press. Ceramage shows higher wear compared with normal enamel,while IPS e.max Press has lower antagonistic war compared with normal enamel.关键词
