Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a plug is filled in tooth extraction nest.

Background

Tooth extraction is the most common treatment for oral surgery. The conventional tooth extraction does not need special treatment, but some teeth with deep tooth roots can leave an extraction socket in the alveolar bone after extraction, which can cause problems of massive bleeding, pain and the like, and can also cause complications such as alveolar bone atrophy, maxillary sinus perforation and the like, and the extraction socket needs to be treated by filling or covering materials in order to prevent and treat the extraction complications.

The traditional filling and covering materials are mainly collagen sponge plugs and bone meal and biological membranes. The collagen sponge plug is prepared by taking collagen as a main raw material, has the effects of stopping bleeding and promoting tissue regeneration, but the collagen is quickly absorbed in vivo, and the collagen possibly has been absorbed before the tooth extraction wound is healed, so that the repair effect is influenced. In addition, the collagen plug has certain elasticity, is not well fixed after being implanted into the tooth extraction wound through filling, has poor adaptability with tissues, is easy to fall out from the tooth extraction socket, causes inconvenient operation and influences the operation effect. The bone powder is filled in the biological film to avoid the bone powder from falling out of the tooth extraction socket, but the bone powder is inconvenient to operate and is easy to scatter at the non-operative position of the oral cavity. And the matching use of the bone meal and the membrane increases the operation time and the treatment cost.
