Description

[Technical field]

[0001] [CROSS REFERENCE TO RELATED APPLICATIONS] This application claims the benefit of priority based on Korean Patent Application No. 10-2023-0079994, filed on June 21, 2023, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to a dentiform for dental treatment practice, and more particularly, to a dentiform for dental treatment practice that forms a dental nerve in the same form as an actual dental nerve inside a tooth root, and allows a patient to master nerve treatment skills such as identification of dental nerve structure and nerve removal surgery through practice. [Background technology]

[0003] Generally, dental nerve treatment is a treatment that is performed when pain is caused by cavities or other factors that have penetrated beyond the dentin of the base body of the tooth (crown) and invaded the dental nerve (pulp cavity and root canal). Once a diagnosis of dental nerve treatment is confirmed, a hole is made in the base body of the tooth with a dental treatment drill tool, and the dental tissue and blood vessels of the dental nerve are removed using an electric nerve removal tool. The cavity of the root canal is then disinfected, and a replacement material is inserted into the cavity and hole of the root canal, making it a type of prosthetic treatment.

[0004] This type of dental nerve treatment can only prevent the recurrence of pain and preserve the natural tooth to the maximum extent possible if the dental nerve is completely removed while minimizing damage to the dentin of the tooth. Therefore, extensive practice is required to master the nerve treatment technique.

[0005] General Dentiform is used for prosthetic restoration, and caries and nerve treatment models are classified as special teeth and can be used for nerve treatment. Currently, general dental schools use models of nerve treatment and caries treatment training teeth for practical training.

[0006] However, the conventional tooth models for training have structural differences from real teeth and are limited in the materials they can be used, which means that the quality of training is lower than when extracted teeth are used. Furthermore, the teeth for training have a short, rounded bottom end, and are fixed with screws or, even if the roots are formed, are filled with plaster or resin to fix them, which limits the training and makes them inconvenient.

[0007] In particular, in the case of teeth with roots used for nerve treatment training, the shape of the root makes it difficult to fix the teeth to a regular Dentifom, so the teeth are fixed using plaster or resin from a syringe for training.In this case, since the teeth can be extracted again after the training, the plaster or resin must be removed, making the process of fixing or separating the teeth complicated and difficult.

[0008] In addition, there is a method in which the tooth root is manufactured flat and then fixed to a standard Dentiform with screws, but this method is not the same as a real tooth, which limits its practical application. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Republic of Korea Patent No. 10-1714667 Summary of the Invention [Problem to be solved by the invention]

[0010] The objective of the present invention is to provide a dentiform for dental treatment practice in which individual teeth consisting of a crown and a root are formed, and a connection guide protrusion is formed on the outer surface of the root to prevent separation when connecting with a tooth fixing block and guide the connection direction, and a dental nerve of the same shape as a real dental nerve is formed inside the root, making it possible to identify the structure of the dental nerve through practice and to master nerve treatment skills such as dental nerve removal surgery.

[0011] Another object of the present invention is to provide a dentiform for dental treatment training, which can stably fix individual teeth with roots formed thereon in accordance with the arrangement of teeth using a tooth fixing block, and which is convenient to use because only the individual teeth that need to be replaced can be separated from the fixing block after training, and the remaining accessories can be recycled.

[0012] Another object of the present invention is to provide a DENTIFORM for dental treatment training that is capable of measuring the root canal length of individual teeth in nerve treatment training. [Means for solving the problem]

[0013] According to one aspect of the present invention, there may be provided a DENTIFORM for dental treatment training, comprising: an individual tooth for which a crown and a root are to be formed; a tooth fixing block to which the root of the individual tooth is detachably connected; and a jaw support to which the tooth fixing block is fixedly installed and which is connected to the temporomandibular joint on either the upper or lower jaw.

[0014] According to another aspect of the present invention, there may be provided a DENTIFORM for dental treatment training, comprising: individual teeth for forming crowns and roots; tooth fixing blocks to which the roots of the individual teeth are detachably connected; a gum portion to which the tooth fixing blocks are assembled according to the arrangement of teeth; and a jaw support to which the gum portion and the tooth fixing blocks are fixedly installed and which is connected to the temporomandibular joint on either one of the upper jaw portion or the lower jaw portion.

[0015] Here, a coupling guide protrusion may be formed on an outer surface of the root of each tooth to prevent separation when coupled to the tooth fixing block and to guide the coupling direction.

[0016] In addition, an internal space may be formed inside the tooth-fixing block, and a clearance space may be formed between the tooth root and an inner surface of the internal space.

[0017] In addition, the inner space of the tooth fixing block may be filled with a conductive gel for measuring the root canal length.

[0018] The tooth-fixing block includes a first half assembled outside the tooth row to sandwich the individual teeth therebetween, and a second half assembled inside the tooth row, the first half and the second half being formed with an internal space filled with conductive gel, an upper frame of the internal space being formed with tooth-fixing holes that cover and fix the outer surfaces of the individual teeth, and a protruding coupling portion that enables male-female coupling between the first half and the second half being formed on the upper and lower frames of the internal space.

[0019] At this time, a coupling guide groove may be formed on an inner surface of the tooth fixing hole, into which a coupling guide protrusion formed on each individual tooth is aligned.

[0020] In addition, the planar shape of the tooth-fixing block may be manufactured in a sector shape whose corners gradually become wider from the inner side to the outer side of the tooth row.

[0021] In addition, a mounting protrusion may be further formed on a lower end of an inner surface of the second half to be fitted to a gum side.

[0022] The gum portion may include a gum body having a U-shaped curvature according to the arrangement of teeth, a bottom portion connecting the inner space of the gum body, and a block assembly guide groove that guides each tooth fixing block to be assembled according to the arrangement of teeth of the gum body.

[0023] At this time, a mounting groove to be coupled with a mounting protrusion of the teeth fixing block may be formed on an inner rim of the block assembling guide groove.

[0024] The jaw support may include a frame body that forms a contour that is the same as the contour of the gum body, an accommodation space configured to accommodate the gum body in an inner space of the frame body, and a bottom body that forms the bottom of the frame body.

[0025] At this time, a teeth row guide groove may be formed in the bottom body so that a lower portion of the teeth fixing block and a lower portion of the mounting protrusion are aligned to maintain the teeth row.

[0026] In addition, a plurality of fastening holes are formed in the bottom body of the chin support, and a locking bolt can be fastened through the fastening holes in a vertical direction from the outside to the inside of the bottom body to fix the gums and teeth fixing block to the chin support.

[0027] In addition, a locking pin is fastened in a horizontal direction from the outside to the inside of the gum body of the gum part, and is fixed by sequentially penetrating the gum body and the tooth fixing block, and one locking pin can be fastened for each tooth fixing block.

[0028] A support means is formed on the bottom of the tooth-fixing block to continuously engage with and support adjacent tooth-fixing blocks, and the support means may include a support leg extending to one side of the bottom of the tooth-fixing block to support a lower portion of the adjacent tooth-fixing block, and a support leg insertion groove recessed in the bottom where the support leg contacts and into which the support leg is inserted.

[0029] In this case, among the tooth-fixing blocks, each tooth-fixing block located at both sides of the tooth row is formed with only a support leg extending toward the center of the tooth row, and the tooth-fixing block located at the center of the tooth row is formed with only a support leg insertion groove on both left and right sides, so that when a pair of tooth-fixing blocks located at both sides of the tooth row are fixed to the gum body using a locking pin, the entire tooth-fixing block can be supported in a chain reaction.

[0030] In addition, the gum portion is divided into a gum body and a bottom portion along a block assembling guide groove, and an outer frame of the block assembling guide groove formed in the gum body is formed with support protrusions that support the lower surface of the tooth-fixing block so that it does not sag, and an inner frame of the block assembling guide groove formed in the bottom portion is formed with mounting grooves that engage with the mounting protrusions of the tooth-fixing block, so that the tooth-fixing block can be fixed in place so as to prevent it from coming off from above and below when the bottom portion and the gum body are coupled together.

[0031] At this time, the bottom of the gum section can be fastened to the bottom body of the chin support by a locking bolt.

[0032] A root canal length measurement hole is formed penetrating laterally through the jaw support, the gum portion and the tooth fixing block, and the root canal length can be measured by inserting a measurement rod into the internal space of the tooth fixing block through the root canal length measurement hole.

[0033] At this time, the root canal length measuring hole and the measuring rod may be formed so as to be coupled to one tooth fixing block.

[0034] A conductor is then installed through the bottom of the tooth fixation block, and electricity can be passed through the jaw support, the conductive gel in the internal space of the tooth fixation block, and the individual teeth.

[0035] A root canal length measuring hole is formed penetrating laterally through the gum portion and the tooth fixing block, and a measuring rod is inserted into the internal space of the tooth fixing block through the root canal length measuring hole, thereby enabling measurement of the root canal length.

[0036] At this time, the root canal length measuring hole and the measuring rod may be formed so as to be coupled to one tooth fixing block.

[0037] A dental nerve may then be formed inside the root of the individual tooth.

[0038] In addition, each individual tooth may have a crown and a root, a dentin layer made of a relatively weak material may be formed on the crown, and a crown layer made of a relatively strong material may be formed covering the outside of the dentin layer.

[0039] The gum portion may be made of either silicone or plastic resin.

[0040] The dentiform may have an upper jaw portion and a lower jaw portion that are connected to each other at a jaw joint portion and can be opened or closed in the vertical direction.

[0041] According to another aspect of the present invention, there is provided a DENTIFORM for dental treatment training, comprising: a tooth fixing block to which the roots of individual teeth are removably attached; and a gum portion to which each of the tooth fixing blocks is assembled in accordance with the arrangement of teeth;

[0042] The tooth fixation block includes a first half that is assembled on the outside of the dentition by sandwiching an individual tooth therebetween, and a second half that is assembled on the inside of the dentition, and the first half and the second half include an internal space that is filled with a conductive gel,

[0043] The gum portion includes a gum body having a "U"-shaped curvature according to the arrangement of teeth, a bottom portion connecting the inner space of the gum body, and a block assembly guide groove penetrating along the "U"-shaped curvature so that each tooth fixing block can be assembled according to the arrangement of teeth;

[0044] The first and second halves of the tooth fixing block are each formed with a hook protruding outward,

[0045] The dentiform for dental treatment practice may be provided, in which a detachable groove is formed in the block assembly guide groove of the gum portion to detachably engage with the hook.

[0046] Here, the hook and the groove may be formed as a linear structure extending in a lateral direction.

[0047] The hook is formed at the lower part of the first half and the second half, and an extension wing is integrally formed extending from the lower part of the hook and operating in conjunction with the elastic deformation of the hook, and a space is formed inside the extension wing to accommodate deformation of the extension wing and the hook.

[0048] A mounting protrusion may be further formed on a lower end of an inner surface of the second half to be fitted to a gum side, and a mounting groove may be formed on an inner rim of the block assembly guide groove to be coupled with the mounting protrusion. Effect of the Invention

[0049] In the present invention, individual teeth consisting of a crown and a root are formed, and a connection guide protrusion is formed on the outer surface of the root to prevent separation when connecting with the tooth fixing block and guide the connection direction, and a dental nerve of the same shape as a real dental nerve is formed inside the root, so that it is possible to identify the structure of the dental nerve through practice and to master nerve treatment skills such as dental nerve removal surgery.

[0050] In addition, the present invention has an economical effect that the tooth fixing block can be used to stably fix individual teeth with roots formed in accordance with the tooth arrangement so that they do not move, and after the training, only the individual teeth that need to be replaced can be separated from the fixing block, making it convenient to use, and the remaining accessories can be recycled.

[0051] The present invention also has the effect of enabling measurement of the root canal length of an individual tooth in nerve treatment training. [Brief description of the drawings]

[0053] Hereinafter, a dentiform for dental treatment practice according to a preferred embodiment will be described in detail with reference to the accompanying drawings. Hereinafter, the same reference numerals will be used for the same components, and repeated explanations and detailed explanations of known functions and components that may obscure the gist of the invention will be omitted. The embodiments of the invention are provided to more completely explain the present invention to those having average knowledge in the art. Therefore, the shape and size of each element in the drawings may be exaggerated for clearer explanation.

[0054] FIG. 1 is a perspective view showing an example of using a Dentiform for dental treatment training according to one embodiment of the present invention by connecting it to a temporomandibular joint portion. Referring to FIG. 1, the Dentiform for dental treatment training 4 according to the present invention can be formed with an upper jaw portion 1 and a lower jaw portion 2 that are connected to each other at a temporomandibular joint portion 3 and can be opened or closed in the vertical direction.

[0055] At this time, by providing the temporomandibular joint portion 3 with a structure similar to that of the temporomandibular joint of the human body, the efficiency of the training is improved.

[0056] Further, the dentiforms 4 forming the upper jaw portion 1 and the lower jaw portion 2 are formed to have the same structure, except that the shape of the teeth of the upper jaw portion and the shape of the teeth of the lower jaw portion are different from each other.

[0057] For ease of explanation, the components of the dentiform 4 forming the upper jaw portion 1 and the lower jaw portion 2 will be denoted by the same names and symbols below.

[0058] The dentiform 4 will now be described in detail with reference to FIGS.

[0059] FIG. 2 is an exploded perspective view showing a dentiform according to one embodiment of the present invention. Referring to FIG. 2, the dentiform 4 of the present invention is broadly composed of individual teeth 41, a tooth fixing block 43, a gum portion 45, and a jaw support 47.

[0060] The individual teeth 41, the tooth fixing blocks 43, the gum parts 45, and the jaw support 47 are formed according to the arrangement of the teeth of the human body. At this time, the individual teeth 41 are coupled to the tooth fixing blocks 43 in units of one or two to prevent separation, and each tooth fixing block 43 is coupled to the gum parts 45, and the gum parts 45 are coupled to the jaw support 47 to prevent separation of each tooth fixing block 43.

[0061] Although Figures 3 and 4 show a configuration in which two individual teeth 41 are coupled to each tooth fixing block 43, the number of individual teeth 41 coupled to one tooth fixing block 43 is not limited to this, and it is also possible for one or more individual teeth to be coupled.

[0062] Below, the individual teeth and the tooth fixing block 43 will be described.

[0063] 3a and 3b are assembled perspective views of a tooth fixation block and an individual tooth according to one embodiment of the present invention, and FIGS. 4a and 4b are exploded perspective views of a tooth fixation block and an individual tooth according to one embodiment of the present invention.

[0064] The tooth fixing block 43 shown in Figures 3a to 4b provides a case structure in which an internal space 433 is formed to which the root of the individual tooth 41 is detachably connected, and the internal space 433 is filled with conductive gel for measuring the root canal length.

[0065] The tooth-fixing block 43 includes a first half 431 that is assembled outside the tooth row with an individual tooth 41 sandwiched therebetween, and a second half 432 that is assembled inside the tooth row.

[0066] The first half 431 and the second half 432 each have an opening on one side and have a housing structure inside, and the first half 431 and the second half 432 are joined together with the openings facing each other to form an internal space 433. At this time, the internal space 433 is filled with a conductive gel and provides a space in which the tooth root 412 of each tooth 41 is accommodated.

[0067] At this time, the first half 431 and the second half 432 have tooth fixing holes 434 formed in an upper frame 435 of an internal space 433 to cover and fix the outer surfaces of the individual teeth 41 .

[0068] The tooth-fixing holes 434 are separately formed on the first half 431 and the second half 432, respectively, and may be manufactured by being molded to be able to closely fit the outer shape of each tooth 41. In this case, the tooth-fixing holes 434 may be manufactured by being molded in a tapered shape that is wide at the top and narrow at the bottom.

[0069] For example, the tooth fixing block 43 can be made of a synthetic resin material that is easy to mold and produce a mold.

[0070] At this time, a male-female coupling structure that allows easy assembly and disassembly may be provided between the first half 431 and the second half 432. To this end, the first half 431 and the second half 432 may be formed with a protruding coupling portion 437 having a male-female coupling structure.

[0071] At this time, the protruding coupling part 437 may be formed on an open edge of the internal space 433 .

[0072] 4a and 4b, an upper frame 435 and a lower frame 436 may be formed wider among the frames around the internal space 433. In addition, a protruding coupling portion 437 may be formed on the upper frame 435 and the lower frame 436 that provide such a wide area.

[0073] At this time, in the protrusion coupling part 437, a pillar-shaped protrusion may be formed on a frame surface of one of the first half 431 and the second half 432, and a protrusion groove into which the protrusion is fitted may be formed on a frame surface of the opposite side. At this time, the diameter of the protrusion groove may be smaller than the diameter of the protrusion, and they may be press-fitted into each other.

[0074] The protrusion of the protrusion coupling part 437 may be manufactured in the form of a cylinder or a square pillar, and the protrusion groove may be formed as a circular groove or a square groove.

[0075] At this time, the tooth fixing hole 434 may have a coupling guide groove 434a formed therein for fixing each tooth 41 in accordance with the tooth row.

[0076] The coupling guide groove 434a may be formed on an inner surface of the tooth fixing hole 434. Also, each tooth 41 may have a coupling guide protrusion 413 formed thereon to be aligned with the coupling guide groove 434a.

[0077] The planar shape of the tooth-fixing block 43 may be manufactured in a sector shape whose corners gradually become wider from the inside to the outside of the tooth row. The tooth-fixing block 43 includes a first half 431 that is assembled on the outside of the tooth row with each tooth 41 sandwiched therebetween, and a second half 432 that is assembled on the inside of the tooth row.

[0078] That is, the teeth fixing block 43 is manufactured in a sector shape that gradually widens from the second half 432 side to the first half 431 side.

[0079] At this time, a mounting protrusion 438 may be formed to protrude from the lower end of the inner surface of the second half 432. At this time, the mounting protrusion 438 is fitted to the gum portion 45 side described later, and is pressed by contacting the lower part of the gum portion 45, thereby fixing the movement of the teeth fixing block 43 between the jaw support 47 and the mounting protrusion 43, thereby preventing the teeth fixing block 43 from coming off.

[0080] At this time, the tooth fixing block 43 may have different outer shapes and internal structures depending on the number of individual teeth 41 to be connected.

[0081] For example, Figures 3 and 4 show an example of combining two individual teeth 41 as one set, and show an example of forming two tooth fixing holes 434 as one set in the upper frame 435 of the first half 431 and the second half 432 of the tooth fixing block 43 to cover and fix the outer surfaces of the individual teeth 41.

[0082] However, the number of such tooth fixing holes 434 may be configured in various forms, such as one, two or more, depending on the number of individual teeth 41 to be coupled.

[0083] FIG. 5 is a perspective view of an individual tooth according to one embodiment of the present invention.

[0084] 5, each individual tooth 41 includes a crown 411 and a root 412. The root 412 is wider on the crown side and gradually becomes pointed toward the bottom. A coupling guide protrusion 413 is formed on the outer surface of the root 412 to prevent separation when coupled to the tooth fixing block 43 and to guide the coupling direction.

[0085] At this time, the coupling guide protrusions 413 may be formed in the front and rear directions of each tooth 41, one for each.

[0086] In addition, a dental nerve 414 may be formed inside the root 412 of the individual tooth 41. At this time, the shape of the crown 411 and the root 412 of the individual tooth 41 can be freely changed depending on the shape of a back tooth, an anterior tooth, etc., and in particular, the root 412 can be freely changed within the range allowed by the internal space 433 of the tooth fixing block 43.

[0087] Since the dental nerve 414 is manufactured with the same shape and texture as the nerve of an actual human tooth, a trainee can practice nerve treatment such as identifying nerve structures and nerve removal under the same conditions as in the real world.

[0088] In addition, each individual tooth 41 is formed with a crown 411 and a root 412, and a dentin layer made of a relatively weak material is formed on the crown 411, and a crown layer made of a relatively strong material is formed on the outside of the dentin layer, thereby providing a feeling similar to that of a real tooth.

[0089] FIG. 6 is a perspective view showing a tooth fixing block being coupled to the dentition of the gum area according to an embodiment of the present invention.

[0090] 6, each tooth-fixing block 43 having one or two individual teeth 41 coupled thereto is arranged according to the tooth row and assembled according to the arrangement of teeth in the gum region 45. At this time, the size and shape of each tooth-fixing block 43 may vary according to the shape of the individual tooth 41 to be coupled thereto, but the names and symbols of the details having the same function and structure are all used in the same manner.

[0091] The gum portion 45 includes a gum body 451 having a U-shaped curvature according to the tooth arrangement, a bottom portion 452 connecting the inner space of the gum body 451, and a block assembly guide groove 453 that guides each tooth fixing block 43 to be assembled according to the tooth arrangement of the gum body 451.

[0092] At this time, a through groove having a U-shaped curvature is formed in the block assembling guide groove 453, and a mounting groove 454 (see FIG. 7) that is coupled with the mounting protrusion 438 of the tooth fixing block may be formed on the inner rim of the block assembling guide groove 453.

[0093] At this time, the gum portion 45 may be made by molding using a synthetic resin material.

[0094] Thereafter, the gum portion 45 and the tooth fixing block 43 are fixedly installed on the jaw support 47 .

[0095] The jaw support 47 can be made of a metal material and serves as a base structure for connecting the Dentiform 4 to the temporomandibular joint 3 of the upper jaw 1 or the lower jaw 2 .

[0096] The jaw support 47 may include a frame body 471 that forms the same contour as the contour of the gum portion 45, an accommodating space 472 configured to accommodate the gum portion 45 in the inner space of the frame body 471, and a bottom body 473 that forms the bottom of the frame body 471.

[0097] At this time, the upper part of the gum portion 45 may be protruded from the frame body 471, and the bottom body 473 may be formed with a tooth row guide groove 474 in which the lower part of the tooth fixing block 43 and the lower part of the mounting protrusion 438 are aligned to maintain the tooth row.

[0098] At this time, the tooth row guide groove 474 may be manufactured in the form of a stepped groove having a “U” shaped curvature similar to the shape of the block assembly guide groove 453 of the gum portion 45 .

[0099] At this time, a plurality of fastening holes 475 may be formed in the bottom body 473 of the chin support 47 .

[0100] At this time, a female thread for screw fastening may be formed in each fastening hole 475. A locking bolt (not shown) may be fastened in a vertical direction from the outside to the inside of the bottom body 473 through the fastening hole 475, so that the gum part 45 and the teeth fixing block 43 may be fixed to the jaw support 47.

[0101] The gum portion may be made of any one of silicone or plastic resin, which is a material having a gum texture.

[0102] FIG. 7 is a bottom perspective view showing a locking structure of a tooth-fixing block according to one embodiment of the present invention.

[0103] Referring to FIG. 7, a locking pin P is fastened horizontally from the outside to the inside of the gum body 451 of the gum portion 45, and is fixed by sequentially penetrating the gum portion 45 and the tooth fixing block 43, and one locking pin P can be fastened to each of the tooth fixing blocks 43.

[0104] At this time, the locking pin P is fastened so as to be inserted into the bottom body of the tooth fixing block 43 without penetrating into the internal space 433 of the tooth fixing block 43 .
