Description

Technical Field

[0002] The restoration is used to repair tooth tissue. Common shapes and types of restorations include inlays, onlays, and crowns. During restoration, the restoration is bonded to the abutment with a bonding resin. There are many types of restoration materials, and glass ceramics are one of the most commonly used ones. When in use, the bonding surface of the glass-ceramic restoration needs to be treated with hydrofluoric acid. Hydrofluoric acid can selectively remove the glass phase in the glass-ceramic, increase the roughness of the inner surface of the ceramic, form a microporous structure, and increase the bonding area. The bonding resin can penetrate into these microporous structures to form a mechanical lock and obtain a strong bond.

[0003] The current treatment method is: wear gloves on both hands, pinch the restoration with one hand, and apply hydrofluoric acid to the bonding surface of the restoration with the other hand for treatment, complete the treatment for a certain period of time, blow it with water in a plastic bag, blow it dry with an air gun, put it in 95% alcohol for vibration, take it out, blow it dry with an air gun, and set it aside.
