超透氧化锆修复体的临床应用现状

Current status of clinical application of ultra-translucent zirconia

氧化锆拥有良好的力学性能及生物相容性,在口腔修复领域已得到广泛使用。但由于传统氧化锆材料半透性较低,在美学表现上仍有所欠缺。随着材料工艺的发展,研究人员通过改善烧结流程等方法开发出新型超透氧化锆材料,从而提高了材料半透性,在美学修复领域开启了新的方向,具有极大的发展潜力。该文从超透氧化锆材料的半透性、机械性能、老化表现及临床操作等方面作一综述,希望对超透氧化锆材料的临床应用提供指导。

Zirconia has been widely used in the field of prosthodontics owe to its good mechanical properties and biocompatibility. However,due to its low translucency and grey appearance, the traditional zirconia still lacks in aesthetic performance. With the development of material technology, researchers has developed new ultra-translucent zirconia material which processes both the good characteristics of traditional zirconia and extraordinary translucency by improving sintering process and other methods. The material has great potential in aesthetic dentistry. In this paper, the properties of ultra-translucent zirconia such as translucency, mechanical properties, aging behaviors were reviewed.
