Description

HYDRAULIC LIFTING APPRATUS FOR SINUS MEMBRANE}

The present invention relates to a mechanism for a maxillary sinus ridge during dental implant surgery, and more particularly, to a maxillary sinus hydrostatic device capable of improving efficiency during implant surgery while minimizing damage or pain to the maxillary sinus lining.

Implants are essentially substitutes that restore the body's tissues when they are lost, but dentistry refers to artificial tooth implantation. This is a state-of-the-art procedure that restores the original function of the tooth by fixing the artificial tooth after planting and fixing a fixture made of titanium that has no rejection to the human body to replace the root of the lost tooth.

In dental implants, in general, the fixture is placed on the alveolar bone to a depth of 7 mm to 14 mm, wherein the thickness of the alveolar bone should be thicker than the implantation depth of the fixture.

On the other hand, when the maxillary region where the maxillary sinus is located, the maxilla of the maxilla is 5 mm, and more frequently, the thickness of the maxilla is maintained due to the extent of the loss of the maxillary bone and the size and location of the maxillary sinus after extraction. Thereby, there is a problem that the fixture can not be placed in the maxilla.

Therefore, when the maxilla is lost, the fixture can be placed after filling the bone substitute on 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 forming a space by lifting the inner membrane of the maxillary sinus and then implanting a bone in a secured space and placing a fixture there.

The vertical approach is a method in which the residual bone is secured to the implantation site to a certain extent, and specifically, when the residual bone has a thickness of 4 mm or more, tap the maxillary bone several times using an osteotom to prevent damage to the maxillary sinus lining. This is a method of making a hole with a diameter of 2 mm to 3 mm and then gradually inserting the graft through the hole.

The vertical approach has the advantage of less edema in the patient after the procedure due to the narrow area, but since the inner maxillary sinus cannot be directly seen during the procedure, the procedure is performed with great care while checking the procedure with X-Ray. This takes a long time, there is a problem that a significant discomfort follows the patient due to the blow in the procedure.

The lateral approach is a method when the residual bone of the implant is very short, specifically, when the thickness of the residual bone is 4 mm or less, by forming a window on the side of the maxillary sinus to lift the inner membrane of the maxillary sinus and then bone-graft through it. Way.

Since the lateral approach can raise the maxillary sinus lining while looking directly during the procedure, there is less damage to the maxillary sinus lining, and even if damage occurs, post-treatment is possible, and a desired amount of bone graft material can be quickly inserted at once, so rapid progress is possible. There is a possible advantage, but the procedure itself is difficult and requires the formation of a large valve, resulting in severe edema after surgery.

Korean Patent Publication No. 10-2010-0088640 discloses a device for colossal maxillary sinuses of the prior art, and FIG. 1 is a view for explaining the procedure of this procedure.

In detail, the vertical approach is used, and FIG. 5A illustrates the formation of a hole to a suitable area below the maxillary sinus by using a twist drill 31, and FIG. 5B shows a dense bone remaining in the lower part of the maxillary sinus by turning a retractor into the formed hole. ), and Fig. 4c illustrates that the dense bone below the maxillary sinus is lifted upward while forming the hatch 43 by the shape of the cork screw at the bottom of the expander, and Fig. 5d is the bone formed by the cutting blade The residues of the 44 are pushed upward along the threaded part, indicating that the inner wall of the maxillary sinus is lifted, and FIG. 5E shows that the maxillary sinus is erected by the cooling water 45 ejected through the main channel 17 formed in the expander. Explain.

However, even in this method, the work is performed depending on the operator's experience and sensation, and thus, the manbrain is often damaged.

In consideration of this, in the present invention, the adapter 100 is interposed for the coupling of the syringe 200 and the handpiece 300, and a detailed description thereof will be described later.

The syringe 200 is connected through the adapter 100, and a water body is accommodated inside the syringe 200.
