Description

[Technical Field]

[0001] The present invention relates to a scanbody for dental implants, and more particularly to a scanbody for improving the accuracy and convenience of scanning multiple scanbodies simultaneously. [Background technology]

[0002] When natural teeth can no longer be used, implant treatment, in which the teeth are extracted and artificial teeth are placed in their place, has become common. This implant procedure involves first implanting a tooth root into the jawbone, fastening an abutment to the tooth root, and then attaching a prosthesis (shaped like a tooth) to the top of the abutment to finally complete the artificial tooth. In recent years, implant procedures have moved away from the analogue methods of the past (manual impression taking) and have evolved into methods that allow for faster and more accurate procedures based on digital information obtained by scanning the oral cavity using a scanner. In such digital implant procedures, it is extremely important to understand the position, depth, and inclination angle of the fixture (tooth root), and the scanbody is used to obtain this information. In other words, the scanbody is attached to a fixture before scanning, and the scanbody is a tool used to display the position of the fixture on the computer screen through the implant / scanbody library during CAD work on implant prostheses. Once the dental clinic sends the oral scan information to the dental laboratory, the laboratory displays the digital oral information on a 3D screen and uses it to create the patient's prosthesis. The CAD production system using scanning as described above not only significantly improves accuracy compared to the traditional manual production of prosthetics because the process is carried out by computer, but also simplifies the treatment process and reduces the number of times patients need to visit the hospital, so its use has been increasing day by day in recent years. Conventionally, the scan bodies used in dental clinics were designed without taking into account the differences in the shape of each tooth, which meant that scanning using multiple scan bodies for two or more implant procedures could result in scanning errors. Due to these issues, practitioners were forced to scan each tooth individually to obtain digital information, which was inconvenient. Summary of the Invention [Problem to be solved by the invention]

[0003] The scanbody set of the present invention aims to accurately generate and store image information from scanning when implant procedures are performed on multiple teeth simultaneously, even when scanbodies are attached to each tooth at the same time and scanning is performed. Ultimately, the technical objective is to realize digital implant procedures that are more accurate and faster, and that minimize inconvenience to patients by reducing the number of visits to the clinic, using the scanbody set of the present invention. [Means for solving the problem]

[0004] The scanbody set according to the present invention has been devised to solve the above technical problems, The head portion (10) is used for the cutting teeth, and is composed of a first cap and a support portion, and the first cap is composed of an inclined surface connected to the upper end of the support portion, a side surface continuing from the inclined surface, a peripheral surface connected to both the inclined surface and the side surface, and a horizontal upper surface continuing from the upper end of the peripheral surface and the side surface; The means for solving the problem is a scan body having a first identification groove (11) formed on the top surface in the shape of a kidney bean and having a certain depth, and a second identification groove (12) formed a predetermined distance from the first identification groove (11) in the shape of a slot and having a certain depth, parallel to or selectively to the first identification groove (11). The scanbody set according to the present invention is used for the canine region, and the head portion (10) is composed of a second cap (200) and the support portion, the second cap (200) is connected to and fixed on the upper surface of the support portion, has a smaller diameter than the support portion, is disc-shaped with a certain height, and is composed of an upper portion (202) connected to and fixed on the upper surface of the lower portion (204) and has a conical shape as a whole, and the upper surface of the upper portion (202) has a first identification groove (11) with a certain depth and in the shape of a kidney bean formed, which is a means for solving the problem. In addition, the scanbody set according to the present invention is used in the premolar area, and the head part (10) is composed of a third cap (300) and a support part, and the third cap (300) as a whole has a conical shape with the upper end cut horizontally, the diameter of the lower surface is smaller than the diameter of the support part, and it is connected and fixed to the upper surface of the support part, and the upper surface of the third cap (300) has one or two kidney bean-shaped first identification grooves (11) of a certain depth formed on it, facing each other at a specified distance, to form a scanbody as a means for solving the problem. Furthermore, the scanbody set according to the present invention is used for the molar region, and the head portion (10) is composed of a fourth cap (400) and the support portion, and the fourth cap (400) as a whole has a conical shape with its upper end cut horizontally, the diameter of its lower surface matches the diameter of the support portion, and it is connected and fixed to the upper surface of the support portion. The fourth cap (400) has a scan body on the upper surface thereof, on which one, two, or three first identification grooves (11) are formed opposite each other at a predetermined distance, or three in three directions, as a means of solving the problem. [Effects of the Invention]

[0005] When multiple implant procedures are to be performed at close or adjacent locations, the scanbody of the present invention can be configured with a unique, different shape for each location. This allows multiple scanbodies to be attached to the oral cavity at the same time, making it possible to obtain information on all fixtures with a single scan. This not only improves the convenience of the procedure, but also reduces unnecessary procedure costs, resulting in very economical procedures. Furthermore, the number of times patients have to visit the hospital can be reduced, which has the effect of dramatically improving convenience from the patient's perspective.

DETAILED DESCRIPTION OF THE INVENTION

[0007] The scanbody set according to the present invention comprises: The head portion (10) is composed of a first cap and a support portion, The first cap is composed of an inclined surface connected to the upper end of the support part, a side surface continuing from the inclined surface, a peripheral surface connected to both the inclined surface and the side surface, and a horizontal upper surface continuing from the upper ends of the peripheral surface and the side surface. A first recognition groove (11) having a certain depth and a kidney bean shape is formed on the top surface. The scan body includes a second identification groove (12) formed in a slot shape with a certain depth at a predetermined distance from the first identification groove (11) and parallel to or selectively to the first identification groove (11). In the following, a scanbody set according to the present invention will be described in detail. The technical terms used in the present invention are merely used to explain the following examples, and are not intended to limit the scope of the present invention. These technical terms should be interpreted as having the meanings that are commonly understood and used by those skilled in the art, unless otherwise defined in the present invention. Before proceeding to a detailed description of the present invention, the unique numbers of each tooth will be explained in order to more accurately describe the present invention. Basically, human teeth are classified into incisors (front teeth, there are two: central incisors and lateral incisors), canines (canine teeth), premolars (there are two: first premolars and second premolars), and molars (back teeth, there are three: first molars, second molars, and third molars). On the other hand, humans have 16 teeth in each of the upper and lower jaws, and these 16 teeth are divided symmetrically, with 8 teeth on each side. The technical feature of the present invention is that by producing scanbodies with different shapes for each tooth as a set, it is possible to simultaneously attach and scan multiple scanbodies when performing implant procedures on multiple teeth. Figure 1 shows a diagram of human teeth with unique numbers. To facilitate understanding of the present invention, each tooth in the oral cavity will be assigned a unique number as shown in FIG. The teeth on the right side of the upper jaw are numbered 11 through 18, going from the front to the back. The teeth on the left side of the upper jaw are numbered 21 through 28, going from the front to the back. Next, the teeth on the left side of the lower jaw will be numbered from 31 to 38, going from the front teeth to the back teeth. The teeth on the right side of the lower jaw shall be numbered from 41 to 48, going from the front teeth to the back teeth.

[0008] Figure 2 shows the general shape of a scanbody used for implant scanning. The scanbody according to the present invention is basically composed of a base portion (30), a main body portion (20), and a head portion (10). The base portion (30) is configured to be connected to an implant fixture, the main body portion (20) is configured to be connected upward to the base portion (30), and the head portion (10) is configured to be connected upward to the main body portion (20) and to indicate a distinctive (identifiable) part during scanning. In other words, the base (30) is a component for fixing the scanbody to the fixture, and the head (10) is the most important part for the scanning process and constitutes the core of the scan data. The scanner ultimately distinguishes between different scanbodies by recognizing differences in the shape of the head (10) of the scanbody. Meanwhile, the head part (10) is composed of a support part (110, 210, 310, 410) corresponding to the lower end thereof and a cap (100, 200, 300, 400) connected to the upper end thereof. The following detailed description of the scanbody according to the present invention will focus on its head. The head basically consists of a cap and a support. For convenience, the perspective views of the head shown in the drawings do not depict a recognition groove on its top surface. Instead, a plan view of the top surface of the head is shown separately below the perspective view, depicting the recognition groove. In other words, the head of the scanbody according to the present invention has a recognition groove of some form formed on its top surface.

[0009] FIG. 3 is a perspective view of the scanbody used in the incisor region. The scanbody used for the incisor parts (11, 12, 21, 22, 31, 32, 41, 42) has a head part (10) that is composed of a first cap (100) and a support part (110). The first cap (100) is composed of an inclined surface (108) connected to the upper end of the support portion (110), a side surface (104) continuing from the inclined surface (108), a peripheral surface (106) connected to both the inclined surface (108) and the side surface (104), and a horizontal upper surface (102) connected to the upper ends of the peripheral surface (106) and the side surface (104). The first cap (100) is generally conical in shape, with the top of the cap cut horizontally and one side partially removed, forming a side surface (104) and an inclined surface (108). The first recognition groove (11) is a groove with a certain depth on the top surface and has an overall bean shape. The second recognition groove (12) is located facing the first recognition groove (11) at a distance, has a certain depth, and is formed in a slot shape. The shapes of the first recognition groove (11) and the second recognition groove (12) are only examples, and can be modified or changed into various different shapes such as circle, oval, rectangle, etc. The first recognition groove (11) and the second recognition groove (12) may be formed independently or simultaneously on the top surface of the first cap. The first recognition groove (11) and the second recognition groove (12) correspond to grooves with a predetermined depth, and their unique overall shape has the effect of improving scanning accuracy. For example, if only one scanbody is to be used in the incisor region, a scanbody with only the first recognition groove (11) can be used, whereas if two scanbodies must be used simultaneously in the incisor region, a scanbody with only the first recognition groove (11) and a scanbody with both the first recognition groove (11) and the second recognition groove (12) can be used simultaneously. This allows the scanner to recognize adjacent scanbodies as different and generate scan data. FIG. 4 is a perspective view of the scanbody in the canine region. The scanbody used for the canine tooth sections (13, 23, 33, 43) has a head section (10) composed of a second cap (200) and a receiving section (210). The second cap (200) is connected to the upper surface of the receiving section (210) and is composed of an upper section (202) and a lower section (204). The lower section (204) has a smaller diameter than the receiving section and is disk-shaped with a certain height. The upper section (202) is connected to the upper surface of the lower section (204) and is generally conical in shape, with the pointed portion of the upper section cut off.

[0010] Although the horizontal cross-sectional shape of the upper portion (202) and lower portion (204) is shown as circular, this is by way of example only, and the cross-sectional shape may be modified to various polygonal shapes, such as triangular, rectangular, pentagonal, etc., and these modified embodiments are considered to be within the scope of the present invention. On the upper surface of the upper part (202), a first recognition groove (11) having a certain depth and a bean shape is formed, similar to the scan body used for the incisor part. The scanbody used for the canine region has a unique head shape (10), which differentiates it from the scanbody used for the incisor region and improves scanning accuracy. For this reason, even when using scanbodies to scan the incisor and canine regions simultaneously, it is possible to attach the scanbodies and scan them simultaneously, without having to scan each region separately. FIG. 5 is a perspective view of the scanbody for the bicuspid region. The scanbody used for the bicuspid tooth portion (14, 15, 24, 25, 34, 35, 44, 45) has a head portion (10) that is composed of a third cap (300) and a receiving portion (310). The third cap (300) has an overall conical shape with a horizontally cut-off top, and the diameter of the bottom is smaller than the diameter of the receiving portion (310) and is connected to the top surface of the receiving portion (310). Although the third cap (300) is shown as having an overall conical shape, this is only an example and the third cap (300) can be modified into various three-dimensional shapes such as a triangular prism, a square prism, a pentagonal prism, etc. The upper surface of the third cap (300) may have one bean-shaped first recognition groove (11) of a certain depth formed thereon, or two first recognition grooves (11) may be formed facing each other at a certain distance. This is to identify the two scanbodies that are used when scanning two premolars simultaneously, allowing two adjacent premolars to be scanned simultaneously and in one operation. Also, the shape of the first recognition groove 11 shown is merely an example, and it can be changed or modified into various different shapes such as a circle, an oval, a rectangle, etc., as described above. FIG. 6 is a perspective view of the scanbody for the molar region. The scanbody used for the molars (16, 17, 18, 26, 27, 28, 36, 37, 38, 46, 47, 48) has a head portion (10) that is composed of a fourth cap (400) and a receiving portion (410). The fourth cap (400) has an overall conical shape with a horizontally cut-off top. The diameter of the bottom of the fourth cap (400) matches the diameter of the receiving portion (410) and is connected to the top surface of the receiving portion (410). In other words, unlike the third cap (300), the fourth cap (400) has a bottom diameter equal to the horizontal diameter of the receiving portion (410) and has an overall conical cylindrical shape.

[0011] There are three molars, as shown in Figure 1. Therefore, three types of scanbodies, each with a unique shape, are required for the molars. The three types of scanbodies used for molars can be configured as follows: i) A scan body (type A) in which only one first recognition groove (11) is formed on the upper surface of the fourth cap (400). ii) A scan body (Type B) in which two first recognition grooves (11) are formed facing each other at a certain distance. iii) A scan body (C type) in which three first recognition grooves (11) are formed in three directions. In addition, in order to improve the accuracy of scanning, these three types of scan bodies used for molars can also have a horizontal band-shaped concave groove (annular groove) formed on the side of the fourth cap (400) or a vertical concave groove of a certain length (vertical groove). As described above, the scanbody set according to the present invention, in which each scanbody has a unique shape, can simultaneously combine multiple scanbodies to obtain intraoral fixture information in a single scan when performing treatment on adjacent, consecutive, or closely spaced implants. Furthermore, the scanbody set according to the present invention is characterized in that the scanbodies present in the upper jaw, lower jaw, left jaw, and right jaw have different shapes. The side of the receiver for the right maxilla (scanbodies used for nos. 11 to 18) has one vertical rectangular groove (500) as shown in Figure 1. The side of the receiver for the left maxilla (scanbodies used for nos. 21 to 28) has two vertical rectangular grooves (500) spaced a certain distance apart. In addition, in one embodiment of the present invention, three vertical rectangular grooves (500) are formed on the side of the receiving part for the left side of the mandible (scanbody used for numbers 31 to 38), and four vertical rectangular grooves (500) are formed on the side of the receiving part for the right side of the mandible (scanbody used for numbers 41 to 48).

[0012] As mentioned above, by forming rectangular grooves (500) on the side of the receiving part and varying the number of them, it is easy to distinguish which part the scanbody is used for. Painting these rectangular grooves (500) with a bright color such as red or blue, rather than a metallic color, will make it easier for the practitioner to distinguish and will also contribute to the accuracy of the scan. Furthermore, the rectangular groove (500) in this invention is merely an example. It goes without saying that it can be changed to a circular groove, a square groove, or any other polygonal groove as long as it is within the range that the scanner can recognize, and these embodiments are also within the technical scope of this invention. Furthermore, it is possible to form the groove in a convex shape instead of a concave shape, and such an embodiment is also considered to be included in the scope of the present invention. The above description of the configuration and effects is of one embodiment of the present invention and does not limit the scope of the claims of the present invention. Various changes and modifications are possible within the scope of the technical concept of the present invention, which are obvious to those skilled in the art, and such simple design changes are considered to be within the technical scope of the present invention. [Industrial Applicability]

[0013] The scanbody set according to the present invention not only improves the convenience of treatment but also reduces unnecessary costs involved in treatment, making treatment very economical. Furthermore, the present invention reduces the number of visits to hospitals by patients, which is convenient for patients.
