Description
Technical Field
The utility model relates to a retention structure for external root canal of separation tooth is filled upside down.
Background
Periapical inflammation still occurs in many affected teeth after endodontic treatment for many reasons that the root canal system and periapical tissue are not completely sealed. In order to create a tight barrier between the root canal system and the periapical tissue to seal off all root canal systems exposed to the periapical tissue, a retrograde root canal filling technique may be used from the apex of the root.
In clinical practice today, root canal treatment may be performed immediately after the tooth is extracted from the diseased jaw bone, and then the fixed tooth is repositioned, which is the intended replantation treatment. However, the inverted root canal of the extracted tooth is often difficult to retain after the tooth is extracted, unstable retention increases the operation difficulty, and meanwhile, if the inverted root canal of the handheld crown is used for treatment, periodontal tissues are easily damaged, thereby being not favorable for the success of tooth replantation. Therefore, we invented a retention method for the in vitro tooth retention method in the tooth extraction immediate back filling process.
Disclosure of Invention
To the weak point of above-mentioned prior art, the utility model provides a problem do: provides a retention structure convenient for an in vitro dental endodontist to perform root canal inverted filling.
In order to solve the above problem, the utility model discloses the technical scheme who takes as follows:
a retention structure for inverted filling of external root canal of in-vitro tooth comprises a tube body, in-vitro tooth and soft bonding material; the pipe body is hollow and has two open ends; the soft bonding material is compacted and filled in the middle of the interior of the pipe body; the upper end surface of the soft bonding material and the inner side of the periphery of the upper end of the pipe body form an injection groove; the longitudinal section of the injection groove is of a U-shaped structure; the lower end surface of the soft bonding material and the inner side of the periphery of the lower end of the pipe body form a pushing groove; the longitudinal section of the pushing groove is of an inverted U-shaped structure; the in-vitro tooth is inversely inserted into the upper end surface of the soft adhesive material; protective liquid is injected into the upper end surface of the soft bonding material in the injection groove; the lower half part of the separated tooth on the upper end surface of the soft adhesive material is immersed in the protective liquid.
Furthermore, the soft adhesive material is a silicon rubber material.
Further, the protective liquid is physiological saline.
Furthermore, the upper end surface of the soft bonding material is of an arc-shaped end surface structure with a large upper part and a small lower part.
Furthermore, the upper end face and the lower end face of the soft bonding material in the middle of the inner part of the pipe body are respectively provided with a distance of 1-2 cm from the upper end face and the lower end face of the pipe body.
Further, the pipe body is of a circular ring cylinder structure.
Further, the body be ya keli body.
Further, the diameter of the pipe body is 2-4 cm.
The beneficial effects of the utility model
