The present invention relates to a fixture that promotes the regeneration of the maxillary sinus to temporarily seal the implant placement hole until the maxillary sinus lining regenerates when the maxillary sinus lining is perforated and damaged during the implant procedure, and more specifically, presses the gums when fastened to the alveolar bone Hemostasis, as well as to facilitate separation by maintaining the gap with the gums, as well as exposing the cell culture membrane that can induce the rapid growth of the inner membrane cells into the maxillary sinus, the damaged maxillary sinus inner membrane can be regenerated in a short time. It relates to a fixture that promotes the regeneration of the maxillary sinus.

In general, dental implants are artificial mediators that restore the function of the lost tooth by burying an artificial medium in the bone tissue of the area where the tooth was lost.

These implants function to restore the natural function of teeth by connecting artificial teeth after fusion of the alveolar bone by planting artificial roots made of titanium or the like that are not rejected by the human body into the alveolar bone.

In the implant procedure, a first procedure is performed in which the implant is placed in the alveolar bone, and the final prosthesis is fixed after waiting for a long time of about 3 to 6 months after the implant is bone-fused (or bone-bonded) to the alveolar bone. It includes.

However, when the maxillary sinus lining is damaged, it occurs not only when the maxillary sinus lining is lifted, but also when piercing the alveolar bone, when an excessive amount of artificial bone is inserted into the mass region of the maxillary sinus lining, and when the implant is placed at an excessively high speed. .

If the maxillary sinus lining is damaged, severe swelling and pain occur in the gums due to the large incision in the side of the maxillary gum and sealing of the damaged maxilla, and also the risk of infection and maxillary sinusitis due to incision of the gums.

In addition, in the past, after sealing the inner maxillary sinus lining along with the side of the maxillary gum, a problem that naturally takes 8 to 12 weeks longer until the maxillary sinus inner membrane is regenerated occurs.

In view of the above-mentioned problems, if the maxillary sinus lining is damaged, there is a need for an implant capable of quickly coping with the need to cut the side of the maxillary gum, and also the damaged maxillary sinus lining can be rapidly regenerated.
