Description

Technical Field

[0001] The utility model relates to the technical field of oral restoration, in particular to a medical crown-removing forceps for oral restoration. Background Art

[0002] Telescopic crowns have a long history of clinical application in stomatology. The retainer of the telescopic crown consists of an inner crown and an outer crown. The inner crown is bonded to the abutment tooth, and the outer crown is sleeved on the inner crown. The outer crown and the inner crown are tightly fitted together to form a retention force, providing retention for removable dentures.

[0003] After searching, the utility model patent with Chinese patent publication number CN211610133U discloses a medical crown removal forceps for oral restoration, which relates to the field of medical equipment. The medical crown removal forceps for oral restoration include a threaded tube and a threaded rod. The threaded tube is provided with a handle and a chuck. The chuck is provided with a circle of flexible ring pads. The threaded rod is provided with a grip ring and a splint. The splint is provided with a flexible block pad. Although the device realizes the mutual approach of the splints by rotating the threaded rod, in actual use, it is inconvenient to adjust its use length, thereby reducing the efficiency of oral restoration.
