Description

Scanning body for implant and implant component containing the same

The present invention relates to a dental implant, and more particularly, to a scan body for allowing a user to more conveniently perform a digital scanning service, and an implant assembly including the scan body ( implant assembly) and an implant method using it.

First, referring to Fig. 1, a dental implant structure in the oral cavity will be described. As shown in the figure, dental implants generally include: artificial tooth roots fixed to the alveolar bone 2, crowns 4 having a shape corresponding to the teeth, and artificial tooth roots 2 and crowns for connecting and supporting the artificial tooth roots 2 4 的 支 台 牙 (abutment) 6.

The artificial tooth root 2 corresponds to a tooth root of a general tooth, is made of a metal material, and is fixed to the alveolar bone using screws formed on an outer surface. The crown 4 corresponds to the crown of the tooth, and is supported in a state where the upper part of the crown 4 is exposed beyond the gums while performing a real function as a tooth. In addition, the dental crown 4 is fixed and supported by the abutment teeth 6 in a state where the artificial crown 2 is connected.

Here, the artificial tooth root 2 has a hexagonal hole formed downward in the artificial tooth root 2, and the abutment tooth 6 has a hexagonal protruding structure formed at a lower end portion thereof and inserted into the hexagonal hole. The hexagonal hole of the artificial tooth root 2 and the hexagonal protruding structure of the supporting tooth 6 are formed to support the supporting tooth 6 combined with the artificial tooth root 2 from being rotated by external force. In addition, instead of hexagonal holes and The hexagonal protruding structure, the artificial tooth root 2 and the abutment tooth 6 may each have a polygonal hole and a polygonal protruding structure which can prevent rotation when they are combined with each other, for example, an octagonal hole and an octagonal protruding structure.

As described above, in a state where the hexagonal protruding structure formed on the lower end portion of the abutment tooth 6 is inserted into the hexagonal hole formed in the artificial tooth root 2, the abutment tooth 6 is passed through the fixing screw (not shown in the figure). And fixed to the artificial tooth root 2. In addition, the crown 4 is fixed to the abutment teeth 6 by an adhesive. Next, a process of performing a dental implant having the above-mentioned structure will be briefly described.

First, after the artificial tooth root 2 is fixed to the alveolar bone, the user waits for a certain period of time, for example, three to four months, until the bone junction of the artificial tooth root is completed. Thereafter, when the osseointegration of the artificial tooth root 2 is completed, in order to treat the gums, the healing abutment tooth (not shown in the figure) is combined with the artificial tooth root 2. Here, the healing abutment teeth perform a function to form an appropriate emergency profile, with the healing gums as a predetermined shape for the crown that will be combined in a later process.

Such healing abutment teeth are divided into a type that is fixed to the artificial tooth root 2 by screws, and a body that is directly fixed to the artificial tooth root 2 because it has a spiral portion integrally formed with the lower end portion and a thread coupled to the artificial tooth root. type,.

After the healing abutment tooth is used to treat the gum to form a predetermined germination shape, the healing abutment tooth is removed, and then it is a manufacturing process of molding dentures fixed to the crown 4 of the artificial tooth root 2. The manufacturing process of puppets is divided into: one is to manually make the shape of the dental crown using impression coping; the other is to obtain a three-dimensional image using an oral scanner using a scanning adapter, and use the three-dimensional image to make the tooth crown.

In the case of the method of directly manufacturing the shape of the crown using the impression cap, the impression cap is combined with the upper portion of the artificial tooth root 2, and then the impression material in a jelly state is coated on the impression cap. Later, when the printed material solidified, the internal shape of the mouth and the shape of the impression cap were recreated in Impression material is then used to make dentures using the same method. However, this method has a disadvantage in that the impression cap makes the patient inconvenient in handling the impression cap and using the film material.

Therefore, in order to overcome the shortcomings of this traditional method, the method of obtaining a three-dimensional image using a digital oral scanner and manufacturing a denture based on the three-dimensional image is a recent development trend. This trend, which meets the convenience of patients and the requirements of the times, is gradually expanding. In order to obtain a three-dimensional image using a digital oral scanner instead of the impression cap used in the above method, the scanning adapter is fixed to the artificial tooth root 2 and then scanned.

As described above, when the user performs a scan to obtain a three-dimensional image of the oral cavity, the scanning adapter is used to accurately grasp the position and direction of the hexagonal hole formed inside the artificial tooth root 2 and is correctly designed to be fixed in Abutment teeth and crown of artificial tooth root 2. In other words, according to the prior art, in order to accurately recognize different gum thicknesses and implant depths caused by the gum thickness and the implant orientation according to the patient, a scanning adapter is used.

However, such a conventional implant method has the following problems.

First, in order to properly design the artificial tooth, in the case of scanning the internal structure of the oral cavity, the scanning must be performed after the scanning adapter is temporarily fixed on the artificial tooth root. Therefore, the patient receiving the implant may be burdened, and the user may feel inconvenient due to the complicated implant process.

In addition, according to the traditional implant process and the structure of the implant component, after the artificial tooth root is implanted into the alveolar bone, the healing abutment teeth serve as separate components when the gums are cured. Although such healing abutment teeth are only used temporarily before the final abutment teeth are fixed to the artificial tooth root, in order to form a germinating shape on the gum, it is necessary to use a healing abutment teeth.

Most traditional healing abutment teeth have a circular cross section, but because the actual shape of the tooth changes with position, the healing abutment teeth differ in shape corresponding to each tooth. Therefore, during the surgical procedure, the patient will feel as the user pushes the artificial teeth into the small healing gums. To a little discomfort, and in more severe cases, the gums may deform. Moreover, this point has a long way to go for recent trends that focus on patient-specific treatments.

Therefore, the present invention is devoted to solving the above-mentioned problems occurring in the prior art, and an object of the present invention is to provide a useful method in a scanning process for obtaining an image in the oral cavity and a treatment process for forming a good germination shape on the gum Implant components.

Reference will now be made in detail to the preferred embodiments of the present invention with reference to the accompanying drawings.

FIG. 2 is a cross-sectional view showing an assembled state of a implant component including a scan body according to the present invention, and FIG. 3 is an exploded cross-sectional view of the implant component. As shown in the figure, the implant component according to the present invention includes an artificial tooth root 10 that combines and supports the alveolar bone, a scanning body 20 that combines the artificial tooth root 10, and a fixing screw 30 that fixes the artificial tooth root 10 and the scanning body 20 to each other.

As described above, generally, the artificial tooth root 10 is combined with the alveolar bone to support the implant. As shown in FIG. 3, the artificial tooth root 10 includes a coupling hole 14 extending from an upper portion to a lower portion, and a hexagonal hole 12 formed in the middle of the coupling hole 14.

Here, the hexagonal hole 12 is used to prevent the scanning body 20 combined with the artificial tooth root 10 from rotating, and may be formed in one of various polygonal shapes such as an octagon. In addition, a spiral portion 18 having an internal thread manufactured on the inner surface is formed at a portion below the hexagonal hole 12, and the spiral portion 18 has a diameter smaller than that of the hexagonal hole and is a portion where the fixing screw 30 is combined.

In addition, the fixing screw 30 is used to fix the scanning body 20 to the artificial tooth root 10, and includes: a spiral portion 32 formed on the lower end portion and having an external thread formed on the outer surface so as to be coupled with the spiral portion 18 of the artificial tooth root 10; And a head 34 formed on the upper end portion and having a diameter larger than that of the fixing screw 30. The fixing screw 30 is basically used to stably support the scanning body 20 to the artificial tooth root 10 by combining the scanning body 20 with the artificial tooth root 10 in a state where the scanning body 20 is inserted into the artificial tooth root 10.

The scanning body 20 is used to accurately obtain a three-dimensional image of the oral cavity to form an emergency profile required by the gums. As shown in FIG. 3, the scanning body 20 has a through hole 21 formed vertically in the middle portion, and a fixing screw 30 is fixed to the artificial tooth root 10 through the through hole 21. In addition, a retaining jam 28 that catches the head 34 of the fixing screw 30 is formed above the through hole 21.

Next, referring to FIGS. 4 to 6, the scanning body 20 will be described in more detail according to the present invention. First, the scanning body 20 according to the present invention has a hexagonal protruding structure 22 formed in the lower end portion and inserted into the hexagonal hole 12 of the artificial tooth root 10. Because the hexagonal protruding structure 22 has a shape corresponding to the hexagonal hole 12 of the artificial tooth root 10, the hexagonal protruding structure 22 has sides in the same direction.

In addition, the body member 24 formed on the scanning body 20 has at least one flat surface member 25. As shown in FIG. 4, the flat surface members 25 have the same angle, for example That is, there may be three flat surface members 25 having the same angle as the sides of a regular triangle. In Fig. 5, a pair of flat surface members 25 are parallel to each other. In FIG. 6, the three flat surface members 25 are at right angles to each other and are adjacent to each other.

Between the body member 24 having at least one flat surface member 25 formed on the upper portion and the hexagonal protruding structure 22 formed on the lower end portion, the connecting member 26 is formed to connect the body member 24 and the hexagonal protruding structure 22 to each other. Because the body member 24 is larger than the hexagonal protruding structure 22, the connecting member 26 has a certain inclination to connect the body member 24 and the hexagonal protruding structure 22 to each other.

The flat surface member 25 of the scanning body 20 is formed substantially parallel to one side of the hexagonal hole 12 of the artificial tooth root 10. As if the flat surface member 25 is parallel to one side of the hexagonal protruding structure 22 of the lower end portion. As described above, in order to obtain correct pattern information when the oral scanner scans an image of the oral cavity, the flat surface part 25 of the scanning body 20 is formed in the same direction as one of the sides of the hexagonal protruding structure 22 or the hexagonal hole 12.

In other words, as described above, using the oral scanner to scan the inside of the oral cavity is to know the correct position when designing the crown. Therefore, since the flat surface member 25 has the same direction as the hexagonal hole 12 of the artificial tooth root 10 when the inside of the oral cavity is scanned with the scanning body 20 loaded on the artificial tooth root 10, the user obtains the image obtained by scanning The image can obtain the correct information about the direction of the hexagonal hole 12 of the artificial root 10 and the depth of the implant.

As described above, in the state where the scanning body 20 having the flat surface member 25 is loaded, since the pattern obtained by the oral scanner includes information on the direction of the hexagonal hole 12 of the artificial tooth root 10 and the depth of the implant, the user can Design the crown correctly. In other words, according to the present invention, the scanning body 20 can scan an image in the oral cavity when it is mounted on the artificial tooth root 10.

As described above, in order to obtain an image in the oral cavity, the prior art has a disadvantage in that the user separates the healing abutment tooth combined with the artificial tooth root 10 and connects the scanning adapter with the artificial tooth root. Scan the inside of the mouth after bonding. However, according to the present invention, the user can directly scan using the scanning body 20 fixed to the artificial tooth root without mounting the scanning adapter on the artificial tooth root, and therefore, the user can conveniently perform the scanning process. Furthermore, in the case of the prior art, the user must combine the healing abutment tooth with the artificial tooth root after scanning with the scanning adapter, but in the case of the present invention, it is not necessary to separate or reload the scanning body 20, the present invention Can provide patients and users with a very convenient operation process.

Next, the function of the scanning body 20 as a healing abutment tooth will be explained. As described above, the healing abutment teeth are maintained in the state of being fixed to the artificial root 10 for a predetermined period of time, so that when the artificial root 10 is implanted into the alveolar bone to cure the gum, a desired emergency profile is formed on the gum. . Because the traditional healing abutment teeth have the same shape regardless of the shape and position of the teeth, patients and users may feel inconvenient in removing the healing abutment teeth and device dentures.

As described above, the scanning body 20 according to the present invention has a first function as a scanning body fixed to the artificial tooth root 10 during a scanning process and a second function as a healing abutment tooth. In other words, after the artificial tooth root 10 is implanted, the scanning body 20 is fixed to the artificial tooth root 10 and the scanning body 20 is maintained in a fixed state for a predetermined period of time, so that the scanning body 20 can form the most on the gum during the process of healing the gums. Optimized germination pattern.

As described above, because teeth have different shapes of cross sections according to the formation of the teeth, the scanning body 20 according to the present invention has at least one flat surface member 25 to form a germination shape having a cross section most similar to a natural tooth. For example, as shown in FIG. 4, the scanning body 20 has three flat surface members 25 with an angle of about 60 degrees to form a regular triangle, and this shape is the cross section most similar to the upper incisor (anterior).

In addition, the scanning body 20 depicted in FIG. 5 has a pair of flat surface members 25 parallel to each other, and this shape is closest to the cross section of the premolar (canine teeth). Depicted in Figure 6 The scanning body 20 has a flat surface member 25 at an angle of about 90 degrees and is adjacent to each other, and this shape is most similar to the molar (back teeth). As described above, the present invention forms at least one flat surface member 25 so as to provide the scanning body 20 having the closest profile to the natural tooth.

Figure 7 depicts an example of the shape of a tooth T. In this way, one can easily find the shape of the cross-section according to the position of the tooth, the shape of the scan body 20 corresponding to each tooth, and the implant position of the artificial tooth root 10, so that the scan body 20 Can be applied to each tooth. Therefore, when the user correctly selects the scanning body 20 having the closest natural tooth profile and fixes the selected scanning body 20 to the artificial tooth root 10 according to the present invention, a germination shape close to the natural tooth can be formed.

The scanning body 20 according to the present invention acts to make the user understand the correct information of the image during scanning and form a desired germination shape when healing the gums. The flat surface member 25 based on the upper body member formed on the scanning body 20 and one side of the hexagonal hole 12 parallel to the artificial tooth root 10 performs two functions. Moreover, since the flat surface member 25 is clear in appearance, the user can grasp the position of the hexagonal hole 12 of the artificial tooth root 10 at a glance.

Then, referring to FIG. 8a, FIG. 8b, and FIG. 8c, the fixing screw 30 for fixing the scanning body 20 to the artificial tooth root 10 will be described. As described above, the fixing screw 30 is used to fix the scanning body 20 to the artificial tooth root 10. Because each person has a different gum thickness, when the scanning body 20 is fixed to the artificial tooth root 10, the length of the fixing screw 30 changes according to the patient. Therefore, the prepared fixing screws are now classified into 4 millimeter (mm) fixing screws, 6 millimeter (mm) fixing screws, and 8 millimeter (mm) fixing screws. Therefore, the user selects an appropriate fixing screw according to the condition of the patient and uses it. The fixing screw fixes the scanning body 20 to the artificial tooth root 10.

After the scanning body 20 is fixed to the artificial tooth root 10 by the fixing screw 30, when viewed from the outside, the type of the fixing screw 30 fixed cannot be visually distinguished. Moreover, if the user does not understand the length of the fixing screw 30 used correctly, problems may occur when designing the dental crown using the images obtained during the scanning process. In other words, When the length of the fixing screw 30 used for the tracing body 20 is described, the user can design the correct prosthesis.

According to the present invention, the mark 38 is formed on the upper surface of the fixing screw 30 so that the user knows the length correctly. Referring to FIG. 8a, FIG. 8b, and FIG. 8c, the mark 38 has grooves of various shapes. For example, the mark 38 in FIG. 8a is a linear groove, and the mark 38 in FIG. 8b has no groove. Reference numeral 38 in the figure 8c is a cross-shaped groove.

In addition, according to the mark 38 of the present invention, the length information of the fixing screw 30 is indicated. For example, it is indicated that the fixing screw 30 has a length of 4 millimeters (mm) in an example of a straight groove and 6 mm in an example of having no groove. In one example, the length (mm) and the cross-shaped groove are 8 millimeters (mm).

Figure 9 depicts another preferred embodiment of the present invention. In this embodiment, the description of the repeated portions will be omitted. As shown in the figure, according to this embodiment, the scan body has a torx type protrusion structure 22a instead of the hexagonal protrusion structure 22. The hexagonal screw cap type protruding structure 22 a has the same function as the hexagonal protruding structure 22. Therefore, the artificial tooth root applied in this embodiment naturally has a hexagonal screw cap type hole corresponding to the hexagonal screw cap type protruding structure 22a formed therein.

The hexagonal screw cap type protruding structure 22a may have the same shape as the hexagonal protruding structure when its six vertexes are actually connected to each other. Therefore, in this embodiment, the flat surface member 25 must also be designed to be parallel to lines connecting adjacent vertices to each other. Further, in the present invention, a polygon means a hexagonal shape, an octagonal shape, or another polygonal shape, and must be defined as a concept to include a shape that appears as a polygon when vertices are connected to each other. Therefore, for example, a hexagonal screw cap type protruding structure or a hexagonal protruding structure is included in the category of a polygonal protruding structure.

Then, according to the present invention, an implanting method using the scanning body 20 will be described. Here, as described above, it is known to use an oral scanner to obtain a three-dimensional image of the inside of the oral cavity and based on the obtained image Technology like designing crowns. Therefore, here, the previously known parts will be described briefly and the features of the present invention will be explained in detail.

First, the user fixes the artificial tooth root 10 to the alveolar bone. After the artificial tooth root 10 is fixed to the alveolar bone, in order to perfectly fix the artificial tooth root 10 to the alveolar bone, a predetermined period of time must elapse. In addition, in order to heal the gums damaged during the implantation process of the artificial tooth root 10, a set time must elapse.

For this reason, after the artificial tooth root 10 is fixed to the alveolar bone, the scanning body 20 according to the present invention is combined with the artificial tooth root 10. The combination of the scan bodies 20 is performed in a state where the hexagonal protruding structures 22 of the lower end portion are inserted into the hexagonal holes 12 formed inside the artificial tooth root 10, thereby preventing the scan bodies 20 from rotating. In the above state, the user fixes the scanning body 20 to the artificial tooth root 10 using the fixing screw 30.

In this example, the fixing screw 30 passes through the through hole 21 of the scanning body 20, and the spiral portion 32 of the lower end portion is coupled with the spiral portion 18 of the artificial tooth root. The head 34 of the fixing screw 30 catches the fixing jaw 28 of the scanning body 20. In addition, the inclined connection member 26 of the scanning body 20 is in close contact with the inclined support surface 16 formed at the entrance portion of the coupling hole 14 of the artificial tooth root 10. Here, the lowest position of the scanning body 20 is defined by the inclined supporting surface 16 of the artificial tooth root 10 and the inclined connecting member 26 of the scanning body 20.

FIG. 2 depicts a coupling state of the fixing screw 30, and in the above state, when a predetermined period of time elapses, the healing of the gums and the fixing of the artificial tooth root 10 are ended. The user then performs a scan of the portion of the oral implant that will be implanted. Scanning is performed by a scanning device, and because such a scanning device and a program for designing a complex based on image information obtained through scanning have been commercialized, detailed descriptions of the scanning device and program will be omitted.

During the scanning process, according to the present invention, the scanning adapter is not used, and The scanning body 20 of the present invention performs scanning while being fixed to the artificial tooth root 10. In addition, as described above, since the scanning body 20 according to the present invention has a flat surface member 25 parallel to one side of the hexagonal hole 12 of the artificial tooth root 10, the user can obtain the direction and position of the artificial tooth root 10 through the mark 38 of the fixing screw 30 Correct information and correct information about the length of the screw portion of the set screw 30. Moreover, based on the three-dimensional images and information obtained through the above, the user can choose the correct design of the crown and optimized abutment teeth.

In addition, according to the present invention, the scanning body 20 has at least one flat surface member 25 as described above. As described above, according to the scan body 20, the user can select one of the scan bodies depicted in Figs. 4 to 6 according to the shape of the patient's teeth. Therefore, when a predetermined period of time elapses after the scanning body 20 is fixed to the artificial tooth root 10, the germination patterns closest to the natural teeth and most suitable for the crown and abutment teeth obtained based on the information will be formed on the gums.

Therefore, when the crown and the abutment teeth are completely designed based on the image information obtained during the scanning process, the fixing screw 30 is removed to remove the scanning body 20, and then, the complete crown and abutment teeth are fixed The artificial tooth root 10 completes the implant surgery. In this example, the abutment teeth are fixed to the artificial tooth root 10 by fixing screws, and the dental crown is fixed to the abutment teeth using an adhesive.

When the present invention is specifically shown and described with reference to the exemplary embodiments thereof, it will be understood by those having ordinary knowledge in the art that various changes in form and details can be made therein without departing from the technical scope of the present invention, and It will also be understood by those with ordinary knowledge in the art that the protection scope of the present invention is interpreted based on the scope of the attached patent application scope.

The scanning body, the implant component and the implant method according to the present invention can be applied to the field of the dental implant industry. The present invention naturally enables the dentist to make a more accurate diagnosis and optimize the design. The present invention can minimize the suffering of patients and provide customized abutment teeth that are most suitable for each patient.
