Description

Intention tooth replantation operation device

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an intention tooth replantation operation device.

Background

The intentional dental replantation is a treatment means for treating teeth with pulp periapical disease, and is a final means for storing such affected teeth mainly aiming at the affected teeth which fail to root canal treatment and cannot be subjected to micro apical surgery. The operation mainly comprises the steps of extracting an affected tooth from an alveolar pit in a minimally invasive manner, cutting off a diseased apical tip in vitro, removing original filling materials in a root canal (a root canal is a structure in the tooth and is used for accommodating nerve blood vessels of the tooth, the nerve blood vessels in the root canal can be removed after the tooth is treated by the root canal, the root canal is filled and sealed by gutta percha) system in the apical area, tightly filling the root canal by using biological materials, and finally implanting the affected tooth back to the original alveolar pit; the method can effectively preserve natural teeth and ensure oral health of patients.

When performing the intentional dental replantation, it is required that the foreign object does not touch the root area of the enamel cementum interface as much as possible. In practice, the crown of the tooth is mainly fixed by hands or dental forceps, however, the area below the root of the cementum junction is still easy to touch, and the affected tooth fixed by hands or dental forceps has the risk of slipping.

There is also an operation tool for an intentional dental implant for fixing a crown of a tooth, in which a plurality of fixing units are combined to fix the crown of the tooth together when the crown is fixed, and the plurality of fixing units form an immersion area for immersing or wetting a root-pressing portion of the tooth, thereby achieving the purpose of fixing the tooth and wetting the tooth root.

Although the current operating tool for the intended tooth replantation can fix the tooth and moisten the tooth root, in the actual use process, the inventor finds that the current operating tool for the intended tooth replantation has the defects, in particular:

because the root of a tooth is usually required to be moistened by using normal saline in the process of the intentional dental replantation operation, at present, when the apical excision of the tooth is carried out by using an intentional dental replantation operation tool, the normal saline is poured into an immersion area, however, when a plurality of fixing units are used for fixing the tooth, if gaps exist among the plurality of fixing units, the normal saline for immersing the root of the tooth is leaked, the root of the tooth is not immersed in the whole operation process, and the surface of the root of the tooth is difficult to keep moist.

Therefore, in view of the above problems, there is a need for an intentional dental replanting device that facilitates the wetting of the tooth surface during an intentional dental replanting operation.
