Description

Fixture position measuring tool for implants {Position measuring tool for implant fixture}

The present invention relates to a fixture position measuring tool for implants, and more particularly, to a position measuring tool for abutment molding according to a fixture planting position.

In general, implants are an aspect of artificial teeth, and are artificial prostheses that restore functions such as mastication, aesthetics, and pronunciation. After implantation is completed, implants have an appearance and function that are difficult to distinguish from natural teeth, and their lifespan is semi-permanent depending on the management status, so it is popularly used.

These implants are largely planted in the alveolar bone, a fixture (artificial root) that serves as the root of the tooth, a prosthesis (crown) that completes the outer upper part of the tooth by covering the artificial crown to be in harmony with the adjacent teeth, and a space between the fixture and the prosthesis It is composed of an abutment (abutment) that connects and plays the role of a pillar.

The fixture is fixed to the alveolar bone, and when a metal such as titanium, which is known to coalesce with the bone, is processed or molded in the form of a screw and inserted into the hole formed in the alveolar bone in advance, the alveolar bone is firmly fixed by coalescing with the fixture and filling the empty space. serves to make

A screw hole for fixing the abutment is formed on the upper part of the fixture, and various abutments are fixed in this screw hole depending on the surgical procedure or use. The abutment for fixing the prosthesis is formed so that the lower end is fixed by a fixture and a screw, and the upper end is covered with the prosthesis so that it can be fixed.

Usually, a hole for fixing the fixture to the alveolar bone is drilled for implant operation, and it should preferably be formed in the center of the position where the tooth was.

However, depending on various environmental factors or the skill of the dentist, it may be formed to be biased to the left or right instead of the center.

Therefore, the fixture may also be located in a position biased to the left and right instead of the original position, and there is a problem in that it is difficult to use a standardized abutment and a prosthesis.

Most of the fixtures are embedded in the alveolar bone to act as the root of the teeth, and the abutments connected to the fixtures are located within the gingiva, except for the parts that connect to the prosthesis, so that they cannot be seen from the outside for aesthetics. Therefore, when the abutment is selected, the abutment corresponding to the individual gingival height is selected. On the other hand, when the fixture is placed vertically perpendicular to the alveolar bone, that is, at an angle parallel to the surrounding teeth, if the abutment coupled to the fixture is selected corresponding to the height of the gingiva, there is no part exposed to the outside of the gingiva, so there is a problem with esthetics there is no However, the oral environment is different for each individual, and if an individual's alveolar bone quality is not good, or if it is not parallel to the surrounding teeth and is placed on the side depending on the shape of the alveolar bone and gingiva, the fixture is placed at an angle. The abutment connected to the fixture also forms an angle, and in this case, the portion where the abutment is exposed to the outside of the gingiva occurs in the area where the gingiva is relatively thin, which is not aesthetically pleasing and causes a number of problems of additional inflammation.

In addition, when the extracted state continues for a long time, part of the alveolar bone is lost in the corresponding part, and the surrounding gums are also deformed.

However, the conventional ready-made abutment has a problem of aesthetics because the margin, which is the coupling line with the prosthesis, is uniform in a straight line, and thus, various individual gingival shapes according to the placement position of the fixture as described above cannot be reflected. In order to improve this point, individual abutments and corresponding prostheses were manufactured for each individual after the fixture was placed according to the individual's oral environment, but this conventional method is complicated and time-consuming and costly to manufacture. Not only did it take a lot of time, but there was a problem in that the patient's waiting time for treatment was long. In addition, in the process of placing the completed abutment and the prosthesis, there may be cases where they do not fit well, and in this case, there is a difficulty in manufacturing the abutment and the prosthesis again.

1 is a block diagram of a fixture position measuring tool for implants according to an embodiment of the present invention.

Referring to FIG. 1 , the fixture position measuring tool 100 for implants according to the present invention may include a central measuring sphere 110 , a left-biasing measuring sphere 120 , and a right-facing measuring sphere 130 .

Although only one example is shown for each of the left deflection measuring sphere 120 and the right directional measuring sphere 130, it includes a number of left and right directional measuring spheres with different degrees of deflection for measuring the degree of deflection to the left or right. can do.

In the description of the present invention, various meanings for 'bias' may be described.

The deflection of the implanted fixture means that the center of the area in which one tooth is lost does not coincide with the center of the fixture, and the deflection of the fixture position measuring tool 100 is a virtual line segment and fixture that passes vertically through the point marking the center. It may mean that the bonding parts do not match.

A description of such a specific configuration will be described later in more detail.

First, the central measuring sphere 110 includes a body 111 and a coupling part 112 positioned at the lower end of the body 111 to be coupled to a fixture (not shown), but the center of the coupling part 112 . and an imaginary line C1 passing through the center of the body 111 in the vertical direction coincides with each other.

A central display unit 113 is positioned at the top center of the front of the body 111 . The central display unit 113 has an inverted triangular engraved structure, and a downward vertex indicates the center of the body 111 .

In addition, a plurality of measurement lines 114 are formed in intaglio on the front surface of the body 111 of the central measuring sphere 110 .

The measurement line of the central measuring sphere 110 and the body 111 is assumed to be in the form of a quadratic function graph with a low center and high both ends.

In addition, the measurement line 114 has a structure in which the height difference between the center and the both ends decreases toward the top. That is, it is assumed that the curvature decreases as the upper measurement line 114 increases.

Each of the plurality of measurement lines 114 is applied, coated, or printed with different colors so that they can be easily distinguished with the naked eye.

Therefore, when the central measuring tool 110 is coupled to the fixture, it is possible to easily check the color matching the gingival line of the gum, so that the implantation depth of the fixture can be easily known. In addition, the measurement line 114 having the most similar curvature to the current state of the patient's gingival line can be easily identified.

The left deflection measuring sphere 120 and the right directional measuring sphere 130 also include bodies 121 and 131, coupling parts 122 and 132, center display parts 123 and 133, and measurement lines 124 and 134, respectively. .

However, the imaginary vertical lines C2 and C3 passing through the centers of the respective coupling portions 122 and 132 of the left deflection measuring sphere 120 and the right directional measuring sphere 130 do not coincide with the centers of the central display units 123 and 133 .

An imaginary vertical line C2 of the left deflection measuring sphere 120 is located on the left side of the central display unit 123 , and the body 121 has a structure deflected to the right with respect to the vertical line C2 .

Conversely, the imaginary vertical line C3 of the right-hand direction measuring sphere 130 is located on the right side of the central display unit 133 , and the body 131 has a structure deflected to the left with respect to the vertical line C3 .

As such, in the present invention, it is possible to check the deflection direction and degree of the placement position of the fixture using the left deflection measuring sphere 120 and the right directional measuring sphere 130 .

2 is an exemplary view of a central measuring sphere 110 of the present invention including a color-coded measurement line 114 .

When the gingival line of the gum and the red measurement line 114 coincide, the set height can be known, and the red measurement line 114 located at the bottom of the gum checks the height protruding out of the gum 1mm or 2mm below the red color It is possible to check the implantation depth of the back fixture.

In addition, by comparing the shape of the patient's gingival line with the measurement lines 114 having different curvatures, and recording the measurement line 114 of the curvature corresponding to the gingival line, it can be used for accurate fabrication of the abutment and the crown.

Alternatively, while various abutments and crowns have been manufactured, select an abutment and crown that matches the placement position, depth, and shape of the gingival line of the fixture so that it can be used immediately.

Therefore, the present invention provides an abutment and abutment that meet various cases with the advantage that it is possible to order an abutment and a crown in accordance with the implantation position, depth, and shape of the gingival line, which are different for each patient, and the order of the exact size is possible. By mass-producing crowns, selecting abutments and crowns that meet the standard, and allowing them to be used immediately, there is an effect of reducing costs due to mass production and reducing the waiting time for patients during the order-made period.

FIG. 3 is a configuration diagram of a state in which the central measuring sphere 110 is coupled to the fixture 200 .

For another reason including a plurality of measurement lines 114 in the present invention, the overall height of the implant may be considered by estimating the heights of surrounding teeth.

That is, in FIG. 3 , the gingival line coincides with the red measurement line 114 , and it can be easily confirmed that the height of the surrounding teeth corresponds to the height of the black measurement line 114 , and the height of the implant can be estimated through this difference. can

In the above example, the central measuring tool 110 is used when a fixture is placed in the center of the gum in the area where there was one missing tooth, and the fixture is usually placed in a position biased to the left or right with respect to this center. occurs frequently.

As such, when the fixture 200 is deflected, it is necessary to check the deflection direction and degree.

If the abutment and the crown are manufactured without considering the deflection, the installation position bias of the fixture 200 interferes with other teeth on the left or right side, making it difficult to install the crown. problems may arise.

In order to confirm the placement position of the fixture 200, the central measuring sphere 110 is first coupled to the fixture 200 to check the state, and it can be determined whether the fixture 200 is oriented to the left or to the right, or whether it is normally placed in the center. have.

If it is determined that the fixture 200 is left-biased, the left-bias measurement sphere 120 is coupled to the fixture.

4 is a schematic diagram of the coupling state of the left-bias measurement tool 120 .

Referring back to FIG. 1 , the left deflection measuring sphere 120 includes a body 121 , a coupling unit 122 , a central display unit 123 , and a measurement line 124 .

At this time, the virtual vertical line C2 passing through the center of the coupling unit 122 passes through the left side of the central display unit 123 .

The figure shows an example of excessively left-biased, and in order to confirm a more precise left-deflection degree, left-deflection measuring instruments 120 having different degrees of deflection are prepared.

For example, the position of the downward vertex of the central display unit 123, which is an inverted triangle, and the interval of the imaginary vertical line C2 passing through the center of the coupling unit 122 are deflected from 0.5 mm to 3 mm in 0.5 mm increments. By making 120 in advance, it is possible to check the exact degree of left deflection using each.

A plurality of measurement lines 124 formed vertically on the front surface of the body 121 of the left deflection measuring sphere 120 are formed in a graph form (parabola form) of a quadratic function having the lowest position of the point through which the virtual vertical line C2 passes. do.

Accordingly, the height of the right end of the measurement line 124 of the left deflection measuring tool 120 is the highest.

As such, the asymmetric shape of the measurement line 124 may be understood as considering the asymmetry of the gingival line at the placement position of the fixture 200 .

In addition, the curvature of the plurality of measurement lines 124 is differentiated to facilitate confirmation of the shape of the gingival line that matches the current state of the patient's gums.

FIG. 5 shows a state in which the left-biased measurement sphere 120 is coupled so that the gingival line coincides with the red measurement line 124 .

That is, a plurality of measurement lines 124 of the left deflection measuring sphere 120 are also provided, respectively, indicating a difference in curvature and color. Therefore, similar to the above-described central measuring sphere 110, the implantation depth of the fixture 200 and the curvature of the gingival line can be checked, and the height of other surrounding teeth can also be checked.

Normally, the gingival line has an inclination of about 6 degrees.

6 is a view showing the coupling state of the fixture 200 of the right direction measuring sphere 130 .

6 and 1 , the right direction measuring sphere 130 includes a body 131 , a coupling unit 132 , a central display unit 133 , and a plurality of measurement lines 134 .

The plurality of measurement lines 134 are formed in an asymmetrical structure in a shape opposite to that of the measurement lines 124 of the left-bias measurement sphere 120 .

That is, the height of the left end becomes higher in a downward parabola shape. This is a form in which the parabolic shape measuring line 114 of the central measuring sphere 110 is moved to the right.

The lowest point of the measurement line 134 is a position through which an imaginary vertical line passing through the center of the coupling portion 132 passes.

Since the plurality of measurement lines 134 have different colors and curvatures, the shape of the gingival line can be easily checked, and the implantation depth of the fixture 200 can be checked.

As such, the present invention is coupled to the fixture placed on the gum so that it is possible to easily check the left or right deflection degree of the fixture, the implantation depth, the shape of the gingival line and the height of the surrounding teeth, so that the abutment and the crown can be manufactured accurately. or to select a suitable product from a variety of pre-manufactured abutments and crowns. Therefore, it is possible to provide an abutment and a crown at a low cost in a short time in the treatment room.

Although the embodiments according to the present invention have been described above, these are merely exemplary, and those of ordinary skill in the art will understand that various modifications and equivalent ranges of embodiments are possible therefrom. Accordingly, the true technical protection scope of the present invention should be defined by the following claims.
