Description

Technical Field

[0001] The utility model relates to the technical field of inlay bonding rods, in particular to an improved bonding rod. Background Art

[0002] Inlay restoration is one of the common methods used in clinical treatment of tooth defects. Inlays are made of different materials and embedded in the tooth to restore the shape and function of the tooth defect. They are restorations or intra-crown retainers. The function is to increase the retention of the crown with the inlay, restore the tooth shape with the cast crown, establish a good occlusal relationship, protect the fragile tooth tissue, and preserve the residual crown of some patients. In the process of tooth restoration, inlay bonding is the last and most important step in the completion of fixed restoration. Good bonding can increase the strength of the restoration and improve the color of the restoration, thereby greatly improving the aesthetic restoration effect. In the process of inlay bonding, bonding rods are usually used for bonding.

[0003] Traditional inlay bonding rods use special glue-like substances for bonding, and the bonding firmness is poor. During wearing, the bonding rod and the restoration may be separated. At the same time, the traditional bonding rod has poor sealing during storage, which makes the bonding surface of the bonding rod easy to dry. Therefore, the utility model proposes an improved bonding rod to solve the above problems. Utility Model Content
