Zirconia Has Excellent Biocompatibility And Wear Resistance
2023/06/14 15:39
As a commonly used artificial material, Zirconia has excellent biocompatibility and wear resistance, and is one of the most commonly used materials in the field of dental restoration. Dental zirconia material is a single crystal material made on the basis of pure zirconia polycrystals. It has the advantages of high strength, high toughness, high light transmittance, high stability, etc. It can be used to prepare all-ceramic teeth, bridges, Implants and other restorations, while zirconia can also be used to make devices such as occlusal occlusal plates. The following is a detailed introduction of dental zirconia:
1. Features: Zirconia has the advantages of high strength, high toughness, high light transmittance, high biocompatibility and wear resistance. Due to its high light transmittance and biocompatibility, the restoration made of zirconia has a natural appearance and a good interface with human tissue, which plays a role in cosmetic and biological restoration. In addition, the mechanical properties and chemical stability of dental zirconia have also been widely recognized.
2. Scope of application: Dental zirconia materials can be used for restoration in the following aspects:
(1) All-ceramic teeth: Zirconia materials can produce all-ceramic teeth similar in color and shape to real teeth, and are currently one of the most commonly used all-ceramic tooth materials.
(2) Bridge: Zirconia materials can also be used to make bridge restorations, which have important applications in oral restoration.
(3) Implants: Dental zirconia materials can be applied to restorations on implants.
(4) Occlusal occlusal plates and other instruments: Zirconia materials can produce high-quality, durable occlusal plates and other instruments, which can effectively correct teeth.
3. Preparation method: At present, there are two main preparation methods for dental zirconia: mechanical processing method and thermal isoform method. Among them, the mechanical processing method is obtained by processing ceramic materials based on zirconia, while the thermal isomorphic method is obtained by using zirconia polycrystals to form a crystal structure at high temperature and then remove unnecessary impurities.
In conclusion, dental oxide materials are widely used in the field of dental restoration, and their unique physical, chemical and biological properties endow it with excellent performance, providing a good choice for oral restoration.
