Description

Technical Field

[0001] The present invention relates to an implant scanner body for dentistry, and more particularly, to a scanner body kit capable of improving scanning accuracy and convenience when simultaneously scanning multiple scanner bodies. Background Art

[0002] When natural teeth cannot be used, treatment by extracting teeth and implanting artificial tooth implants at that position has become a common treatment method. This implant surgery includes implanting a fixture in the jawbone, connecting an abutment to the implant, and then installing a denture (a shape similar to a tooth) similar to the tooth shape on the upper part of the abutment, thereby finally completing the process of artificial teeth.

[0003] In recent years, implant surgery has evolved from the past analog method (i.e., by manually taking impressions) to a method of more rapid and precise treatment using digital information obtained by an oral scanner.

[0004] In this digital implant treatment, it is very important to accurately grasp information such as the position, depth, and inclination angle of the fixture, and the scanner body is designed to obtain this information.

[0005] In other words, after connecting the scanner body to the implant and performing a scan, the scanner body is a tool for displaying the position of the implant, which serves as the tooth root, on the computer screen through the implant / scanner body library when performing CAD design of the implant denture.

[0006] When a dental hospital sends oral scan information to a dental laboratory, the laboratory will display the received digital oral information in a 3D image and fabricate the patient's denture based on this.

[0007] As described above, the system for CAD design through scanning is automatically completed by a computer, so compared with the conventional method of manually fabricating dentures, it not only significantly improves accuracy but also simplifies the treatment process, thereby reducing the number of times the patient visits the hospital, and its application scope has been continuously expanding in recent years.

[0008] However, the scanner bodies used in traditional dental hospitals do not distinguish between the shapes of each tooth. When two or more implant surgeries are required, if multiple scanner bodies are installed and scanned simultaneously, there will be a problem of scanning errors. Due to this problem, the operator has to separately scan each tooth to obtain digital information, resulting in inconvenience. Summary of the Invention

[0009] Technical Problem The implant scanner kit for improving the accuracy of oral scanning (hereinafter referred to as the scanner kit) of the present invention solves the problem that when implant surgeries are performed on multiple teeth simultaneously and scanners can be installed on each tooth and scanned simultaneously, image information can be accurately generated and saved.

[0010] Ultimately, the scanner kit of the present invention aims to achieve a more accurate, faster digital implant surgery that can reduce the number of patient visits and thus minimize inconvenience.

[0011] Technical solution To solve the above technical problems, the scanner kit of the present invention is conceived as follows: The scanner for the incisor part includes: The head 10 is composed of a first cap body and a support part. The first cap body includes an inclined surface connected to the top of the support part, a side surface extending from the inclined surface, a peripheral surface connecting the inclined surface and the side surface, and a horizontal upper surface connecting the peripheral surface and the top of the side surface; A first identification groove 11 with a certain depth and in the shape of a kidney bean is formed on the upper surface, and a second identification groove 12 in the shape of a groove with a certain depth is formed in parallel or selectively at a certain interval from the first identification groove 11.

[0012] According to the present invention, the scanner for the canine part includes: The head 10 is composed of a second cap body 200 and the support part. The second cap body 200 is connected and placed on the upper surface of the support part. It has a disk-shaped bottom 204 with a diameter smaller than that of the support part and a certain height, and a top 202 with an overall conical shape connected and placed on the upper surface of the disk-shaped bottom 204; A first identification groove 11 with a certain depth and in the shape of a kidney bean is formed on the upper surface of the top 202.

[0013] According to the present invention, the scanner for the premolar part includes: The head 10 is composed of a third cap body 300 and the support part. The top of the third cap body 300 is horizontally cut and has an overall conical shape. Its bottom diameter is smaller than that of the support part, and it is connected and placed on the upper surface of the support part; One or two first identification grooves 11 with a certain depth and in the shape of a kidney bean are formed on the upper surface of the third cap body 300 at a certain distance from each other.

[0014] According to the present invention, the scanner for the molar part includes: The head 10 is composed of a fourth cap body 400 and the support part. The top of the fourth cap body 400 is horizontally cut and has an overall conical shape. Its bottom diameter is the same as that of the support part, and it is connected and placed on the upper surface of the support part; One, or two opposite each other at a certain distance, or three first identification grooves 11 in three directions are formed on the upper surface of the fourth cap body 400.

[0015] Effect of the Invention According to the scanning body kit of the present invention, when implant surgeries are performed at multiple adjacent or neighboring sites, scanning bodies with different unique shapes can be provided for each position, so that multiple scanning bodies can be installed in the oral cavity simultaneously, and the position data of all implants (fixtures) can be obtained through a single scan. This not only improves the convenience of the surgery, but also reduces unnecessary costs, achieving a highly cost-effective treatment method.

[0016] On the other hand, since the number of patient visits can be reduced, from the perspective of the patient, there is also an improvement in the effect brought by great convenience. Description of the Drawings

Detailed Description of the Invention

[0018] Best Mode for Carrying Out the Invention According to the scanning body kit of the present invention, the scanning body includes: The head 10 is composed of a first cap body and a support part; The first cap body includes an inclined surface connected to the upper end of the support part, a side surface extending from the inclined surface, a peripheral surface connecting the inclined surface and the side surface, and a horizontal upper surface connecting the peripheral surface and the top of the side surface; A first identification groove 11 with a certain depth and in the shape of a kidney bean is formed on the upper surface, and a groove-shaped second identification groove 12 is formed parallel or selectively at a position at a certain distance from the first identification groove 11.

[0019] Specific Embodiment The scanning body kit according to the present invention will be described in detail below.

[0020] The technical terms used in this specification are only for explaining the following embodiments and are not intended to limit the scope of the present invention by the above technical terms. Unless otherwise specifically defined in the present invention, they should be understood as the meanings commonly understood and used by those skilled in the art.

[0021] Before elaborating on the present invention in detail, for a more accurate understanding of the present invention, the numbers of each tooth will be described first.

[0022] Basically, human teeth can be divided into incisors (i.e., front teeth, including a pair of central incisors and a pair of lateral incisors), canines (i.e., cuspids), small molars (i.e., premolars, divided into a pair of first premolars and a pair of second premolars), and large molars (i.e., molars, including three molars: the first molar, the second molar, and the third molar). In addition, there are 16 teeth in each of the upper and lower jaws of humans, arranged symmetrically left and right, with 8 teeth on each side. The technical feature of the present invention is that by designing different-shaped scanning bodies for each tooth and forming a scanning body kit (set), when performing implant surgery on multiple teeth, multiple scanning bodies can be installed and scanned simultaneously.

[0023] Figure 1 It is a schematic diagram showing the numbers given to human teeth.

[0024] To enhance the understanding of the present invention, the teeth in the oral cavity are respectively given exclusive numbers as Figure 1 shown.

[0025] The teeth on the right side of the upper jaw are numbered from 11 to 18 in sequence from the front teeth to the molars, and the teeth on the left side of the upper jaw are numbered from 21 to 28 in sequence; The teeth on the left side of the lower jaw are numbered from 31 to 38 in sequence, and the teeth on the right side of the lower jaw are numbered from 41 to 48 in sequence.

[0026] Figure 2 It is a diagram showing the general shape of the scanning body for implant scanning.

[0027] The scanning body according to the present invention basically consists of a base portion 30, a body portion 20, and a head portion 10.

[0028] The base portion 30 is connected to the implant fixture; the body portion 20 is connected upward to the base portion 30; the head portion 10 is connected upward to the body portion 20 and is the part that shows characteristics (differences) during scanning.

[0029] In other words, the base portion 30 functions to fix the scanning body on the fixture, and the head portion 10 is the most important part during scanning and is the core of the scanning data. The scanner distinguishes different scanning bodies by recognizing the shape differences of the head portion 10 of the scanning body. The head portion 10 is composed of supporting portions 110, 210, 310, 410 located below and cap bodies 100, 200, 300, 400 connected above.

[0030] The following will focus on the head structure of the scanning body in the present invention. Basically, the head is composed of a cap body and a support part. In the perspective view of the head shown in the figure, for the sake of convenience of description, the identification groove formed at the top is omitted; and a top plan view is separately drawn below the perspective view to show the identification groove. In other words, according to the present invention, an identification groove of a certain shape is provided at the top of the head of the scanning body.

[0031] Figure 3 It is a perspective view of the incisor part scanning body.

[0032] The scanning body applicable to the incisors 11, 12, 21, 22, 31, 32, 41, 42, its head 10 is composed of a first cap body 100 and a support part 110.

[0033] The first cap body 100 is composed of an inclined surface 108 connected to the upper end of the support part 110, a side surface 104 connected to the inclined surface 108, a peripheral surface 106 connecting the inclined surface 108 and the side surface 104 at the same time, and an upper surface 102 in the horizontal direction extending from the upper ends of the peripheral surface 106 and the side surface 104. The first cap body 100 as a whole presents the shape of a cone whose upper end is horizontally cut, and a part of one side surface is cut off to form a unique outer shape. An inclined surface 108 and a side surface 104 are formed on the cut-off side.

[0034] The first identification groove 11 is a groove with a certain depth, and the whole is in the shape of a kidney bean. The second identification groove 12 is arranged opposite to the first identification groove 11 at a certain distance and is in the shape of a groove. The shapes of the above-mentioned identification grooves are only examples, and can also be changed into various shapes such as circular, oval, rectangular, etc. according to needs.

[0035] The first identification groove 11 and the second identification groove 12 can be set separately or can be set on the top surface of the first cap body at the same time. Since the first identification groove 11 and the second identification groove 12 are grooves with a certain depth and have a unique overall shape, it helps to improve the accuracy of scanning.

[0036] For example, when only scanning one incisor, the scanning body with only the first identification groove 11 can be used, and when scanning two incisors at the same time, the scanning body with only the first identification groove 11 and the scanning body with both the first identification groove 11 and the second identification groove 12 can be used at the same time, so that the scanner can distinguish adjacent scanning bodies and generate data.

[0037] Figure 4 It is a perspective view of the canine part scanning body.

[0038] A scanning body applicable to the canine teeth 13, 23, 33, 43, the head 10 of which is composed of a second cap body 200 and a support portion 210. The second cap body 200 is connected to and disposed on the upper surface of the support portion 210, and it is composed of a top portion 202 and a bottom portion 204. The diameter of the bottom portion 204 is smaller than the diameter of the support portion, and it is in the shape of a disc with a certain height; the top portion 202 is connected to and disposed on the upper surface of the bottom portion 204, and its overall shape is conical, and the shape of the top cone is horizontally cut.

[0039] The horizontal cross-sections of the illustrated top portion 202 and bottom portion 204 are circular, but this is only an embodiment, so it can also be various polygons such as triangles, rectangles, pentagons, etc. Such modified embodiments also belong to the technical scope of the present invention.

[0040] On the upper surface of the top portion 202, there is also a first identification groove 11 with a certain depth and in the shape of a kidney bean, which is the same as the scanning body used for the incisor teeth.

[0041] The scanning body used for the canine teeth is that its head 10 has a unique inherent shape, which is different from the scanning body used for the incisor teeth, so as to improve the accuracy of scanning. Therefore, even when it is necessary to use the scanning body to scan the incisor teeth and canine teeth at the same time, there is no need to perform separate scans respectively. The scanning body can be installed at the same time and then scanned.

[0042] Figure 5 It is a three-dimensional view of the scanning body for the premolar teeth.

[0043] A scanning body applicable to the premolar teeth 14, 15, 24, 25, 34, 35, 44, 45, the head 10 of which is composed of a third cap body 300 and a support portion 310.

[0044] The top of the third cap body 300 is horizontally cut and its overall shape is conical. The diameter of its lower end is smaller than the diameter of the support portion 310, and it is connected to and placed on the upper surface of the support portion 310. The illustrated third cap body 300 is conical, but this is also only an embodiment, so it can also be changed to various three-dimensional shapes such as triangular prisms, quadrangular prisms, pentagonal prisms, etc.

[0045] On the top of the third cap body 300, there is a first identification groove 11 with a certain depth and in the shape of a kidney bean, or two first identification grooves 11 that are opposite to each other at a certain distance are formed.

[0046] This kind of setting is to distinguish the two scanning bodies when scanning two premolar teeth at the same time, so that adjacent two premolar teeth can be scanned at the same time, and the scanning can be completed through a one-time operation.

[0047] The shape of the illustrated first identification groove 11 is only an embodiment, and it can also be considered that various shapes such as circles, ellipses, rectangles, etc. can be modified and changed as needed are described.

[0048] Figure 6 It is a three-dimensional view of the molar scanning body.

[0049] The scanning body is applicable to the molars 16, 17, 18, 26, 27, 28, 36, 37, 38, 46, 47, 48, and its head 10 is composed of a fourth cap body 400 and a support part 410.

[0050] The top of the fourth cap body 400 is horizontally cut and the whole is in a conical shape. Its bottom diameter is the same as the diameter of the support part, and it is connected and placed on the upper surface of the support part 410. That is to say, different from the third cap body 300, the fourth cap body 400 has the same horizontal diameter and bottom diameter, and the whole is in a conical shape.

[0051] There are three molars as Figure 1 shown, so three scanning bodies with unique shapes need to be equipped.

[0052] The three scanning bodies for molars include: the scanning body (Type A) with a first identification groove 11 formed on the upper surface of the fourth cap body 400, the scanning body (Type B) with two first identification grooves 11 formed at a certain distance and opposite to each other, and the scanning body (Type C) with three first identification grooves 11 formed in three directions.

[0053] In addition, in order to improve the scanning accuracy, the three scanning bodies for molars can also form a transverse strip-shaped groove (ring-shaped groove) or a groove with a certain longitudinal length (vertical groove) on the side surface of the fourth cap body 400.

[0054] As described above, according to the scanning body kit of the present invention, each scanning body has a unique shape. Therefore, even when multiple implants are implanted adjacent to or continuously, multiple scanning bodies can be installed simultaneously and scanned at one time, so as to obtain detailed data of the implants in the oral cavity.

[0055] In addition, the scanning body kit of the present invention is characterized in that the shapes of the scanning bodies for the upper jaw, lower jaw, left side, and right side are different.

[0056] For the scanning body used for the right side of the upper jaw (No. 11 to No. 18), as Figure 1 shown, a longitudinal rectangular groove 500 is formed on the side surface of the support part; for the scanning body used for the left side of the upper jaw (No. 21 to No. 28), two longitudinal rectangular grooves 500 are formed on the side surface of the support part at a certain interval.

[0057] In addition, for the scanning body used for the left side of the mandible (No. 31 to No. 38), three longitudinal rectangular grooves 500 are formed on the side surface of the support part; for the scanning body used for the right side of the mandible (No. 41 to No. 48), four longitudinal rectangular grooves 500 are formed on the side surface of the support part. This is an embodiment of the present invention.

[0058] By providing different numbers of rectangular grooves 500 on the side surface of the support part, the applicable positions of each scanning body can be more intuitively distinguished. The colors of these rectangular grooves 500 can be not special metallic colors, but colored with colors (such as red, blue, etc.), which is convenient for the operator to distinguish and may also improve the accuracy of scanning.

[0059] Of course, the above-mentioned rectangular grooves 500 are only an embodiment. As long as the scanner can recognize the grooves, the grooves can also be other different polygonal grooves such as circular and quadrangular. Such variant embodiments also belong to the technical scope of the present invention.

[0060] In addition, it can also be changed to a convex positive engraving structure, and these changes should also belong to the protection scope of the present invention.

[0061] The description of the above composition and effects is only an embodiment of the present invention and should not be regarded as limiting the scope of the claims of the present invention for patents; without departing from the technical idea of the present invention, those skilled in the art can make various changes and modifications, and these changes and modifications all belong to the technical scope of the present invention.

[0062] Industrial Application The scanning body kit described in the present invention not only improves the convenience of the operation, but also reduces unnecessary operation costs, realizing an economical and efficient implant surgery.

[0063] In addition, the present invention can also reduce the number of times the patient travels back and forth to the hospital, thus providing better convenience.
