氧化锆全冠的临床应用原则及新进展

Clinical application principles and new developments of zirconia crown

氧化锆全冠在口腔修复领域得到了广泛的应用。传统氧化锆机械性能佳,但半透性较差,透明氧化锆的出现大大提高了氧化锆的美学性能。但在临床中,应对影响全锆冠美学修复效果的因素进行综合考量,选择最合适的全锆冠修复体,同时临床医师需要根据患者实际情况合理设计牙体预备量以及预备方式。在氧化锆的临床粘接过程中,要对基牙和修复体做好表面处理,选择合适的粘接剂以获得良好的粘接强度和美观性。

Zirconia crown has been widely used in the field of prosthodontics.Traditional zirconia exhibits excellent mechanical properties but lacks translucency.The introduction of transparent zirconia significantly enhances its aesthetic performance.In clinical applications,factors affecting the aesthetic results of full zirconia crown should be comprehensively considered,and the most suitable restoration should be chosen.Additionally,clinicians need to design appropriate tooth preparation dimensions and methods based on an individual patient’s actual situation.During the clinical bonding process of zirconia,proper surface treatment of the tooth and restoration is essential.The selection of suitable adhesives is crucial for achieving optimal bonding strength and aesthetics.
