全锆冠机械性能的研究现状及与临床应用的关系

Mechanical properties of monolithic zirconia crowns and its relationship with clinical application

临床中可供全锆冠修复选择的氧化锆材料种类较多。传统全锆冠以机械性能见长,而透明氧化锆冠的美学性能更佳、机械性能相对较弱。材料选定后,临床操作和修复后口内使用均会对全锆冠的机械性能产生影响。本文从临床角度出发,对修复设计、加工制作、试戴、粘接和口内使用的全流程中如何结合全锆冠机械性能进行临床决策,以及临床过程如何对其机械性能产生影响等问题进行总结及探讨,为全锆冠的临床应用和研究提供参考。

Many types of zirconia materials are available for monolithic zirconia crown restoration in clinic.Traditional monolithic zirconia crowns have advantageous mechanical properties,while transparent zirconia crowns have favourable aesthetics but poor mechanical properties.After selecting the material,the mechanical properties of monolithic zirconia crowns are affected by clinical operation and intraoral use.With a whole clinical perspective including design,fabrication,try-on,bonding and intraoral use,this review intends to summarise and discuss problems such as making clinical decisions with the mechanical properties of monolithic zirconia crowns and determining the effects of clinical procedure on the mechanical properties to provide reference for the clinical application and research of monolithic zirconia crowns.
