硅基陶瓷的临床应用现状与展望

Clinical application and prospects of silica based ceramics

硅基陶瓷是现代口腔美学临床修复的首选材料之一,近年来应用广泛。硅基陶瓷以玻璃相为主,具有良好的美观性、粘接性及生物相容性等诸多优势,但是其机械性能略差,可以根据材料组分与加工方式制作不同种类的修复体以满足不同的临床需求。课题组在PubMed、中国知网(CNKI)、万方等数据库中以“硅基陶瓷、玻璃陶瓷、物理性质、剪切强度、粘接表现、临床操作、表面处理”为中英文关键词检索相关文献。按照纳入与排除标准筛选后,对最终纳入的45篇文献进行归纳总结。通过查阅文献分析总结硅基陶瓷的种类与特点、硅基陶瓷修复体的临床应用以及硅基陶瓷的粘接技术,在此基础上对硅基陶瓷未来发展趋势进行展望,同时结合现在技术从中得到新启迪。硅基陶瓷具有理想的应用前景,但对于硅基陶瓷技术更多拓展应用的可行性还有待科学实验验证与临床实践观察。

Silica based ceramics are one of the preferred dental esthetic restorative materials for modern dental clinical treatment,which have been widely used in recent years.Silica based ceramics are mainly glass phase,with excellent esthetic,adhesive properties and biocompatibility,but slightly poor mechanical properties.According to different kinds of material components and processing methods,various restorations can be made to meet the clinical needs.Our research group searched for the articles in PubMed,CNKI,Wanfang databases with the key words of"silica based ceramics;glass ceramic;physical properties;shear bond strength;bonding performance;clinical operation;surface treatment"in Chinese and English.After screening with the inclusion and exclusion criteria,45 articles were included.Upon the included literature,the types,characters,clinical applications and bonding technologies of silica based ceramic restorations were reviewed and summarized.Furthermore,the future development trend of silica based ceramics was prospected,and new inspiration was obtained by combining the silica based ceramics with the current technology.Silica based ceramics have an ideal application prospect,but the feasibility of more extensive application of silica based ceramics technology needs scientific verification and clinical observation.
