Description

Insert for raising the maxillary sinus membrane {The insert for raising, that membrane of the maxillary sinus}

The present invention relates to inserts used for the elevation of the maxillary sinus membrane during implant procedures in dentistry.

In dentistry, implantation refers to a series of procedures for implanting artificial teeth.

These implants are implanted in the alveolar bone where the teeth are missing, fixation without bone rejection to the human body, bone fusion and bonding the abutment to the fixture, and then fix the artificial tooth to the abutment to replace the missing tooth with an artificial tooth Technology.

Unlike prosthetics or dentures, which cause teeth and bones to deteriorate over time, implants have the advantage of being very similar to natural teeth without damaging dental tissue.

Due to the characteristics of such implants, the recent implant procedures are being performed a lot domestically and internationally.

The general implant procedure does not require a high level of skill, but in the case of an implant procedure involving the maxillary sinus, it is difficult to perform the procedure, and a relatively high level of skill is required.

The reason for the difficulty in implantation in the maxillary molar is that most of the maxillary molar need an artificial bone graft into the maxillary sinus due to lack of residual bone.

In order to proceed with artificial bone implantation in the maxillary sinus, it is necessary to lift the thin maxillary sinus membrane, ie, elevate the maxillary sinus membrane and implant artificial bone in its place.

However, because the maxillary sinus membrane is thin, it is not easy to elevate the maxillary sinus membrane while preventing the maxillary sinus membrane from being perforated.

As a technique for solving such a problem, an insert for an implant procedure such as Korean Patent Registration No. 10-0889233 has been devised.

The above technique is a technique of spraying saline or the like in the direction of the maxillary sinus membrane in the state where the insert is inserted into the perforated maxillary sinus, and causing the maxillary sinus membrane to be elevated by the pressure of the injection.

(The maxillary sinus membrane retains the elevated state even when the pressure is removed from the elevated state and does not completely return to the state before the elevated state.)

However, the conventional insert as described above has a problem that the maxillary sinus membrane is narrow and elevated.

That is, as shown in Fig. 1A, the width is narrow and the height of elevation is high.

Elevation in this form has a problem that the implantation of bone, which is a material of artificial bone, is narrow, so that a hard implant procedure is difficult.

In addition, the conventional insert is a fluid such as saline solution is directly injected toward the maxillary sinus membrane, and the expansion pressure is concentrated at a specific point, there was a problem that various side effects such as rejection occurs.

The present invention is intended to solve the above problems, and more specifically, to provide a implant for insert implants that can elevate the maxillary sinus membrane in an easy form for a solid implant procedure, and eliminates the risk of perforation of the maxillary sinus membrane. have.

In the present invention, the expansion body capable of inflation and contraction, such as a balloon, is inflated under the pressure of air or fluid in the state of being inserted into the maxillary sinus, but is expanded in a shallow form with a wide width and height to facilitate the implantation. Elevated form and fluids such as saline is not in direct contact with the human tissue so that less side effects.

Such an implant procedure insert of the present invention is insertable into the maxillary sinus, has a flow path formed therein, and has an insert pole in which a discharge port connected to the flow path is perforated.

In addition, it is connected to one side of the insert pole and the expansion of the maxillary sinus membrane while expanding under the pressure of air or fluid supplied through the flow path of the insert pole, it has an expansion body that is contracted when the pressure is removed and separated from the maxillary sinus.

It is also connected to the insert pole and has an expansion pressure generating means for pushing air or fluid into the expansion body through the flow path of the insert pole.

Further, when the inflating body is inflated by the movement of the inflating pressure generating means, it is inflated more in the lateral direction than in the longitudinal direction.

When the insert for the implant procedure of the present invention is used, an expansion body capable of inflation and contraction, such as a balloon, is inserted into the maxillary sinus and expands under pressure of air or fluid, but expands in a shallow and wide shape to expand the maxillary sinus membrane.

Therefore, when the maxillary sinus membrane is elevated, the stiff implant procedure is elevated in an easy form.

In addition, fluids such as saline are not in direct contact with human tissues, and the pressure is distributed evenly, so there are fewer side effects.

Hereinafter, the technical spirit of the present invention will be described in more detail with reference to the accompanying drawings.

It is to be understood, however, that the appended drawings illustrate only typical embodiments of the present invention and are not to be considered as limiting the scope of the invention.

The present invention relates to inserts for the elevation of maxillary sinus membranes.

Therefore, the insert of the present invention is also insertable into the maxillary sinus 1 as in the prior art, the flow path 11 is formed, and has an insert pole 10 in which the discharge port 12 connected to the flow path 11 is drilled.

It is also connected to the insert pole 10 and has an expansion pressure generating means 20 for pushing air or fluid through the flow path 11 of the insert pole 10 toward the maxillary sinus membrane 2.

The expansion pressure generating means 20 is mainly implemented in the form of forcing the movement of air or fluid by moving the piston, such as a syringe.

Since the insert pole 10 or the expansion pressure generating means 20 as described above is already known, a detailed description thereof will be omitted.

However, the present invention is capable of elevating the maxillary sinus membrane in a form that is easy for a solid implant procedure in pushing the air or fluid through the inflation pressure generating means 20 to elevate the maxillary sinus membrane 2, and inserts for implant surgery having fewer side effects. Has a purpose to provide.

For this reason (11) in the present invention is connected to one side of the insert pole 10 and expands under the pressure of air or fluid supplied through the flow path 11 of the insert pole 10, the coarse maxillary sinus membrane, the contraction when the pressure is removed It has an expansion body 30 which is separated from the maxillary sinus.

In addition, the expansion pressure generating means 20 is capable of pushing air or fluid into the expansion body 30 through the flow path of the insert pole 10.

In addition, when the expansion body 30 is inflated by the movement of the inflating pressure generating means 20 is to be expanded in the lateral direction more than the longitudinal direction.

In other words, when the maxillary sinus membrane is elevated, as shown in B of FIG. 1, the implant is easy to be implanted in a wide and shallow form, and the implanted artificial bone is easily received into the blood stream and is easily formed into a bone, so that a solid implant procedure is performed. It is possible.

In addition, the fluid or air, such as saline, supplied for the elevation of the maxillary sinus membrane, is not directly in contact with the human body, and the maxillary sinus membrane is perforated due to an even pressure distribution, rather than a strong pressure applied to a specific site. Is less.

The expansion body 30, which is a component of the present invention, expands under pressure, such as a balloon, and contracts when the pressure is removed.

The expansion body 30 is preferably implemented in a material with less rejection to the human body.

The expansion body 30 is expanded under the movement of the inflation pressure generating means 20, that is, the pressure of the supplied air or the fluid, but when the expansion body 30 is inflated, the structure is expanded more in the lateral direction than the longitudinal direction is Various implementations are possible.

As a specific example, as shown in FIG. 3, the lateral thickness of the expansion body 30 is thinner than the thickness of the upper portion, so that the expansion ratio in the lateral direction is better.

In another embodiment, as shown in FIG. 4, the discharge hole 12 formed in the insert pole 10 is pierced in the lateral direction, so that the expansion ratio in the lateral direction is better.

Of course, the method of forming the discharge port 12 in the lateral direction has a difference that the effect is significantly lower than when the side thickness is thinner than the upper thickness.

However, when the discharge port 12 is formed laterally in a structure where the side thickness is thinner than the thickness of the upper portion, a very excellent effect can be obtained.

In the present invention, the insert pole 10 can be implemented in the form of the base body 13 and the insertion body 14 bent from the base body 13 as shown in FIG.

According to this structure, it is convenient to insert the expansion body 30 into the maxillary sinus or to operate the inflation pressure generating means to elevate the maxillary sinus membrane.

The angle θ (see Fig.) In which the base body 13 and the insertion body 14 are bent is preferably about 110 ° to 160 °, more preferably 130 ° to 140 °.

The expansion body 30 and the insert pole 10, which is a component of the present invention, is preferably implemented to be separated and coupled.

In addition, it is preferable to implement the insert pole 10 and the expansion pressure generating means 20 to be separated and combined.

If it can be separated or combined, it can be used by replacing only that part, such as when a failure occurs in a specific component or when it reaches the end of its life.

In particular, the inflation body 30 may be implemented as a single use to replace the inflation body 30 for each patient.

As the separation and coupling method, a well-known technique used in various industries such as a spiral coupling method may be applied.

In addition, as shown in FIG. 5, a high elastic rubber ring 40 or a coupling method using a packing may be used.

In other words, the rubber ring 40 or the packing is to pressurize and fix the expansion body 30 inserted into the insert pole 10.
