In-Ceram材料是一种相对较新的全陶瓷修复材料，其性能有所改善，需要进行研究。修复材料的临床选择是基于一些参数，如美学，适合和强度。本研究测定了In-Ceram系统部件的弯曲强度，并将芯材与传统的菱晶陶瓷和Dicor全瓷修复材料进行了比较。每种陶瓷的弯曲棒的四点弯曲强度值为：In-Ceram烧结氧化铝为18.39 +/- 5.00 MPa，In-Ceram灌注玻璃为76.53 +/- 15.23 MPa，In-Ceram灌注氧化铝芯为236.15 +/- 21.94 MPa。自上釉的金刚石瓷的弯曲强度为69.74 ± 5.47 MPa，铸态Dicor瓷为71.48 ± 7.17 MPa，抛光Dicor瓷为107.78 ± 8.45 MPa。
In-Ceram material is a relatively new all-ceramic restorative material with improved properties that require research. The clinical selection of restorative materials is based on a number of parameters such as esthetics, fit, and strength. This study determined the flexural strength of In-Ceram system components and compared the core material with conventional feldspathic ceramics and with Dicor all-ceramic restorative material. Four-point flexural strength values of bend bars of each ceramic were 18.39 +/- 5.00 MPa for In-Ceram sintered alumina, 76.53 +/- 15.23 MPa for In-Ceram infusion glass, and 236.15 +/- 21.94 MPa for In-Ceram infused alumina core. Flexural strength of self-glazed feldspathic porcelain was 69.74 +/- 5.47 MPa, as-cast Dicor ceramic 71.48 +/- 7.17 MPa, and polished Dicor ceramic was 107.78 +/- 8.45 MPa.
