Description

Adapter for maxillary sinus cavities {ADAPTOR FOR MAXILLARY SINUS LIFT}

The present invention relates to an adapter for maxillary sinus elevation and to an adapter for maxillary sinus elevation that can elevate and prevent damage to the maxillary sinus lining.

Implant is a substitute that recovers when the tissue of the human body is lost, but in the dentistry, it refers to an artificial tooth implant. It is a cutting-edge procedure to restore the original function of teeth by fixing artificial teeth after planting and fixing a fixture made of titanium without rejection to the human alveolar bone to replace the missing tooth root.

In the dental implant procedure, the fixture is generally implanted in the alveolar bone with a depth of 7 mm to 14 mm, wherein the thickness of the alveolar bone should be thicker than the depth of implantation of the fixture.

On the other hand, in the case where the maxillary sinus is located in the maxilla, the maxilla is lost to 5 mm, more frequently less than the thickness of the maxillary sinus due to the loss of the remaining maxilla and the size and position of the maxillary sinus. As a result, there is a problem in that the fixture can not be placed in the maxilla as it is.

Therefore, when the maxilla is lost, the fixture can be implanted after filling the bone substitute to the upper part of the maxilla, that is, the maxillary sinus.

Conventionally, there is a vertical approach and a lateral approach as a method of implanting bone into a secured space after implanting the maxillary sinus lining to form a space.

The vertical approach is when the remaining bone is secured to the implant site to some extent, specifically when the thickness of the remaining bone is 4mm or more, by tapping the maxillary bone several times using osteotomy to prevent damage to the maxillary sinus lining. A hole of 2 mm to 3 mm in diameter is then inserted into the graft bone little by little.

The vertical approach has the advantage of less swelling in the patient after the procedure because of the narrower surgical site, but because the lining of the maxillary sinus cannot be seen directly during the procedure, the procedure is performed very carefully while confirming the process with X-Ray. This takes a long time, there is a problem that the patient is accompanied by a significant discomfort due to the blow in the procedure.

The lateral approach is a method when the remaining bone of the implant site is very insufficient, specifically when the thickness of the remaining bone is less than 4mm, forming a window on the side of the maxillary sinus to elevate the inner lining of the maxillary sinus and then do bone graft through it. That's the way.

Since the lateral approach can elevate the maxillary sinus lining directly during the procedure, there is little damage to the maxillary sinus lining, and even if damage occurs, post-treatment is possible and rapid implantation of the desired amount of bone graft can be done at once. There is a possible advantage, but the procedure itself is difficult to form a large valve there is a problem that occurs severe edema after surgery.
