Ionomer-based cement is a new bone replacement material. After promising results have been obtained with this material in middle ear and skull base surgery as well as in plastic reconstructive surgery, this material can be used to fix a cochlear implant system (internal receiver as well as the electrode) to the temporal bone. This material is formed via a reaction of a glass powder with a polycarboxylic acid. The cement has a manipulation period of about 5 minutes. After setting, the cement is well tolerated by tissue and has the additional advantage of being biocompatible and permanently stable in a biological environment. The cement and the acid are commercially available as a two-component capsulated system. In cochlear implant surgery this material is used to achieve a stable attachment of the internal receiver to the temporal bone. Displacement and damaging of the internal receiver and the electrode are prevented.
基于离子聚合物的骨水泥是一种新型骨替代材料。在中耳和颅底手术以及整形重建手术中使用该材料取得了良好效果后，这种材料可用于将人工耳蜗系统（内部接收器以及电极）固定到颞骨上。该材料通过玻璃粉末与多元羧酸反应形成。这种骨水泥的操作时间约为5分钟。凝固后，该骨水泥能被组织良好耐受，并且具有生物相容性以及在生物环境中永久稳定的额外优点。该骨水泥和酸以双组分胶囊系统的形式在市场上销售。在人工耳蜗植入手术中，这种材料用于实现内部接收器与颞骨的稳定附着，防止内部接收器和电极发生移位和损坏。
