Description

Artificial Tooth Model For Training Of Teeth Scaling Treatment And Teeth Scaling Treatment Training Appliance {Artificial Tooth Model For Training Of Scaling And Training Appliance For Teeth Scaling}

The present invention relates to a dental training apparatus used for training of tooth scaling, and more particularly, a training apparatus for tooth scaling having a structure in which artificial calculus is reproduced on the surface of a tooth model (model) to enable scaling practice. is about

Scaling is a dental treatment that professionally removes calculus, which is a cause of gum disease that cannot be removed by regular brushing.

Tartar means that the dental plaque (dental plaque) is made by depositing minerals such as calcium (Ca) and phosphorus (P) in saliva and the gingival sulcus (space between teeth and gums). Tartar can be classified into supragingival calculus and subgingival calculus according to the location of its formation.

Supragingival calculus refers to tartar above the gum line, and is most often formed around the salivary glands, on the lingual side of the mandibular incisors and on the buccal side of the maxillary molars, the crown of teeth without occlusion, non-functioning teeth, unmaintained teeth, It can also be calm around dentures and other prostheses.

In general, when oral hygiene management is not performed properly, supragingival calculus is accumulated on the tooth surface just above the gums along the boundary between the teeth and the gums from a relatively young age.

In addition, subgingival calculus is located on the proximal surface between all teeth and teeth below the gum line, at the lingual root (the root of the lingual part of the tooth), is dark brown, cannot be observed with the naked eye, is hard like flint, and is produced due to sulcus effusion. do.

General tartar removal is a treatment method focused on supragingival calculus in order to compensate for the lack of regular oral hygiene and to prevent the progression to deeper gum disease when tartar is left unattended and increased in quantity. Gum disease with mild gingivitis can be relieved of inflammation and restored to a healthy state with only thorough scaling and tooth brushing.

However, if you have passed the preventive stage and have progressed to gum disease (periodontal disease, tooth decay) that cannot be controlled only by scaling to remove supragingival calculus, more in-depth periodontal treatment is required to restore the condition of the gums and teeth to a healthy state. .

When gum disease becomes a problem, it is important to remove the subgingival calculus during the treatment process, since subgingival calculus attached along the root of the tooth under the gums as well as the subgingival calculus are the main causes.

More specifically, since the subgingival calculus is hidden under the gums and is not in a position where it can be seen directly, it is necessary to find it using a detailed instrument and scrape it out together with the surrounding inflamed tissue (periodontal surgery).

In addition, when the periodontal pocket is deep due to the severe destruction of the gum bone, calculus and inflamed tissue are removed while directly viewing the treatment area by surgical method exposing the tooth root and alveolar bone in the area to be treated.

The above-mentioned tartar removal procedure, that is, tooth scaling, is for the purpose of smoothing a rough tooth surface or preventing reattachment by physically removing hard or soft deposits attached to the teeth in the oral cavity and lubricating the tooth surface. It's a dental procedure.

Dental caries (cavities) and periodontal disease, the representative oral diseases, are caused by the development of dental plaque on the surface of the teeth. It is difficult to remove the tartar that has gradually hardened with only brushing. Scaling has the effect of removing bad breath and preventing oral diseases such as periodontal disease by removing the dental plaque and tartar and lubricating the tooth surface.

As an instrument used for scaling, that is, a scaler, there are an ultrasonic scaler (ultrasonic calculus remover) and a manual scaler that scrapes tartar manually. In order to minimize the patient's pain or anxiety during the scaling procedure, scaling training, that is, practice (practice) is required. It is difficult to experience the practice, and since scaling involves pain, it is difficult to find a target for scaling practice for inexperienced people with scaling, for example, trainees, prospective dentists, or preliminary dental hygienists.

First, referring to FIGS. 1 to 8 , an embodiment 10A of an artificial tooth model for training of a tooth scaling procedure according to the present invention and an embodiment 100 of a dental arch model (dentiform) having the same are described. do.

Artificial teeth 10 forming a dental arch are provided on the model base 110 forming the skeleton of the above-described arch tooth model, and at least one of the artificial teeth 10 is removed by a scaler. By being provided with an artificial calculus (surface foreign material) that becomes, the artificial tooth model 1 for training of the above-described tooth scaling procedure as in the examples shown in FIGS. 7 and 8 is formed.

The artificial tooth 10A of FIG. 5 is an anterior model, that is, a real model manufactured in the shape of an incisor (middle incisor), that is, an artificial anterior teeth, and the artificial tooth 10B of FIG. it's guchi

The arch tooth model 100 for scaling operation training is implanted in the model base 110 forming the skeleton of the arch tooth model, and the alveolar bone portion of the model base 110 to form the dental arch of the arch tooth model. The artificial teeth 10 that are provided on the surface of the model base 110 and corresponding to the soft tissue in the oral cavity in the maxillary tooth model, for example, the artificial gingiva 120 forming a gum portion, and the artificial teeth It includes an artificial calculus 20 provided on the surface of at least one of them.

That is, the tooth-shaped models forming the dental arch on the model base 110 of the arch tooth model, that is, the surface of at least one of the artificial teeth 10, are provided with artificial calculus, that is, a surface foreign material, thereby scaling teeth. Forms artificial tooth models for training of procedures.

The model base 110 has a structure having a hard part corresponding to the jaw bone and is made of a hard material such as plastic or gypsum. And in the portion to which the artificial teeth 10 are coupled, that is, the alveolar bone portion 111 (alveolar bone corresponding portion) of the above-described model base is formed with tooth holes in which the aforementioned artificial teeth 10 are implanted, and the alveolar bone corresponding portion 111 is formed. is covered by the artificial gingiva 120 described above. Accordingly, the arch tooth model 100 has a structure similar to the inside of a human oral cavity.

And the artificial gingiva 120 is a part corresponding to the soft tissue in the oral cavity, for example, a part corresponding to the gums, and may be made of soft silicone or rubber.

The artificial teeth 10 are made of a hard and hard material such as a resin or a ceramic material. Each of the artificial teeth 10 includes a crown-corresponding portion 11 exposed to the outside of the artificial gingiva 120 and a root-corresponding portion 12 positioned inside the artificial gingiva. The root-corresponding portion 12 is fitted and fixed in the tooth hole 111a formed in the alveolar bone-corresponding portion 111 of the model base 110 .

In this embodiment, all of the artificial teeth 10 are detachable. In other words, all of the artificial teeth 10 are replaceable, and all of the artificial teeth 10 can form the artificial tooth model 1 for training of the above-described scaling procedure. For reference, the artificial tooth model 1 shown in FIG. 7 is an example in which artificial calculus is formed on the surface of artificial teeth, especially artificial anterior teeth.

The artificial teeth 10 may be detachably fixed to the model base 110 by screws. For example, a screw hole 13 is formed on one end surface of the artificial tooth 10 accommodated in the tooth hole 111a, and a deep part of the tooth hole is formed in the model base 110. A penetrating screw assembly hole 111b is formed, and the screw S is inserted into the screw assembly hole 111b and fastened to the screw hole 13 of the artificial tooth through the screw assembly hole 111b. A female screw is formed in the screw hole 13 of the artificial tooth.

Accordingly, the artificial tooth model 1 for training of the tooth scaling procedure according to an embodiment of the present invention includes an artificial tooth 10 that can be placed in the alveolar bone portion of the model base, and an artificial tooth provided on the surface of the artificial tooth. and calculus (20).

The artificial calculus 20 may include at least a kind of calculus part among a first calculus part forming an artificial subgingival calculus and a second calculus part forming an artificial subgingival calculus. That is, supragingival calculus and/or subgingival calculus may be reproduced on the surface of the artificial tooth 10 . Accordingly, it can be seen that the first calculus part forms artificial calculus exposed to the outside of the artificial gingiva 120 .

The artificial calculus 20 is a surface foreign material that is integrally attached to the surface of the artificial tooth and is removed from the surface of the artificial tooth by scaling. Since the artificial calculus 20 may be formed on the surface of the artificial tooth in various shapes, various types of artificial calculus removal practice, that is, scaling simulation practice may be performed.

The artificial calculus 20 may include an adhesive 20a applied to the surface of the artificial tooth 10, and powdered artificial calculus particles 20b attached to the tooth surface by the adhesive 20a. can

The adhesive 20a is a base substrate for forming a foreign material layer on the surface of the artificial tooth 10, and the artificial tartar particles 20b are embedded in the adhesive 20a in the form of a solid powder (Powder). input), that is, it is fixed to the surface of the artificial tooth 10 in a mixed form. As the artificial calculus particles 20b, particles having a size of several nanometers to hundreds of nanometers, that is, nanopowder may be used, but the size of the particles is not limited thereto. Particles with a size of micro to hundreds of micrometers, that is, micro powder are also possible.

As the adhesive 20a, a dental adhesive, for example, cyanoacrylate, which is widely used as a medical and dental adhesive, may be used, but is not limited thereto, and an eugenol-based adhesive, such as zinc oxide eugenol cement, may be used. Dental adhesives such as (Zinc Oxide Eugenol Cement) can also be used.

Of course, since the arch tooth model is an instrument for simulation practice, a general adhesive, for example, an epoxy adhesive or a urethane adhesive, which is not for dental or medical use, may be used to form the artificial calculus.

The artificial calculus particles 20b are grains mixed with the adhesive constituting the base material of the artificial calculus, and at least one type may be selected from the group consisting of metallic particles and non-metallic particles. In this embodiment, as the artificial tartar particles 20b, a powder of a radiation shielding material, for example, one or more powders selected from the group consisting of tungsten, bismuth, barium sulfate and boron, etc. may be used. there is.

As described above, when the artificial calculus 20 contains the powder of the radiation shielding material, if the dental arch model is radiographically taken after the calculus removal simulation using the arch tooth model, the artificial tartar removal state and the practitioner's scaling ability can be checked/evaluated.

The artificial calculus 20 may have a multi-layer structure. For example, the artificial tartar; It may include a first calculus layer 21 directly and integrally attached to the surface of the artificial tooth 10 , and a second calculus layer 22 laminated on the outside of the first tartar layer 21 .

Another calculus layer may be further added between the first calculus layer 21 and the second calculus layer 22 . In other words, the second calculus layer 22 may be directly laminated on the outside of the first calculus layer 21 or indirectly laminated through another calculus layer as a medium.

In addition, the first tartar layer 21 and the second tartar layer 22 may be formed of materials having different adhesive strengths or may have different colors. That is, the adhesive of the first calculus layer 21 and the adhesive of the second calculus layer 22 may have different adhesive strength, and different types of artificial calculus particles may be applied to each layer, and the first calculus Pigments or artificial tartar particles of different colors may be applied to the layer 21 and the second tartar layer 22 . Of course, the artificial calculus particles may not be included in at least one layer of the multi-layered artificial calculus, for example, the first tartar layer and/or the second tartar layer.

By applying/curing the adhesive 20a in which the artificial calculus particles 20b are mixed to the surface of the artificial tooth 10 , the artificial calculus 20 may be formed on the surface of the artificial tooth 10 . .

As an example of a method of forming the artificial calculus 20 in multiple layers, first, the adhesive 20a in which the artificial calculus particles 20b are pre-mixed on the surface of the artificial tooth 10 is partially applied (for example, For example, the first calculus layer 21 is formed by applying it to the lingual side of the anterior model) and hardening, and on the first calculus layer 21 in the same manner as the first calculus layer for forming the same or different type of artificial calculus The material may be applied/cured to form the second tartar layer 22 . The shape of the artificial calculus may be diversified according to the number of times of application/hardening of the material for forming artificial calculus and/or the application location/area of the material for forming artificial calculus.

Of course, after applying the adhesive 20a to the surface of the artificial tooth 10 and before the adhesive 20a is cured, the artificial tartar particles 20b are sprayed on the surface of the artificial tooth where the adhesive 20a is attached. By doing so, the artificial calculus particles 20b may be embedded in the adhesive 20a, and multiple layers of artificial calculus may be formed by repeating this process.

In the training of the scaling procedure using the above-described arch tooth model 100, the removal state of artificial calculus, that is, the scaling ability and proficiency, may be confirmed through visual identification, but the removal of the artificial tartar by detecting (tracking) the movement of the scaler. You can also check the status through the monitor.

Another embodiment of the dental scaling procedure training apparatus according to the present invention is a display unit for outputting a dental arch model 100 for training of tooth scaling, and a state of removal of the artificial calculus by a scaler in training of the tooth scaling procedure (200) may be included.

More specifically, the dental scaling procedure training device includes a dental arch model 100, a display unit 200 for outputting the removal state of artificial calculus on the screen, a memory 300 for storing data, and a scaler ( 30) and may include a control unit 400 that detects movement and processes various data.

The shape data of the arch tooth model 100 including the shape of each artificial tooth and the shape data of the scaler are stored in the memory 300, and the scaler 30 includes a sensor for detecting the movement of the scaler; That is, a sensor such as a motion sensor is provided. For example, a sensor for detecting the motion of the scaler 30 is provided on the handpiece (handle part) of the scaler 30, and the shape data of the scaler and the motion signal of the scaler 30 input from the sensor The displacement of the scaler tip is calculated based on .

The arch tooth model 100 is fixed at a predetermined position, that is, at predetermined coordinates. For example, the arch tooth model inside the mouth 101 of the head model 100A so that the arch tooth model 100 is positioned/mounted in the head model 100A of the face shape in which the mouth 101 is formed. A model mounting unit for mounting the (100) is provided, and the arch tooth model 100 is mounted to the model mounting unit. Based on the coordinates (fixed coordinates) of the model mounting unit and the shape data of the arch tooth model, coordinates for each part of the arch tooth model and a 3D shape of the arch tooth model may be output to the display unit 200 . The arch tooth model 100 of FIG. 1 is an example of a tooth model in which the teeth of the lower teeth are formed, that is, the tooth model of the mandible.

In order to detect a three-dimensional displacement of the scaler with respect to the arch tooth model 100 , an initial position (coordinate) of the scaler with respect to the arch tooth model 100 may be set. The setting of the scaler is a method of placing the scaler 30 in a setting unit of a specific position to which fixed coordinates are given in advance, such as a model mounting unit for the arch tooth model, and setting the coordinates of the position as the initial setting coordinates of the scaler. can be performed with As described above, when the arch tooth model is fixed at a preset position (model mounting unit) and the setting of the scaler is completed before scaling starts, the coordinates of the arch tooth model and the scaler can be set with respect to a predetermined coordinate reference. Of course, the setting of the scaler may be made by an optical detector.

As described above, when the relative position of the scaler with respect to the head model 100A, in particular, the arch tooth model 100 is set, the relative three-dimensional displacement of the scaler with respect to the arch tooth model 100, In particular, the movement of the scaler tip (the tip of the scaler in contact with the artificial calculus) may be input to the control unit 400 from a sensor provided in the scaler, and the relative movement of the scaler tip with respect to the arch tooth model 100 . The movement of the scaler tip may be tracked based on , and the removal state of the artificial calculus may be calculated based on data such as the distance between the scaler tip and the surface of the artificial tooth and the position of the scaler tip. For example, when the scaler tip is positioned on the part to which the artificial calculus is attached and the distance between the scaler tip and the artificial tooth surface is smaller than the thickness of the artificial tartar, the artificial calculus is removed by the difference.

The control unit 400 includes a signal receiving unit and a data processing unit, and the signal receiving unit receives a displacement signal of the scaler 30 from a sensor provided in the scaler 30 .

The data processing unit obtains locus data of the scaler from the shape data of the scaler and data such as a displacement signal of the scaler input to the signal receiving unit.

As shown in FIG. 9 , the control unit 400 may include an image processing unit. The image processing unit generates an image of the arch tooth model from the shape data of the arch tooth model 100 and the coordinates of the arch tooth model, and the image of the scaler from the trajectory data of the scaler and the shape data of the scaler create That is, the image processing unit implements the shape and movement of the scaler and the shape of the arch tooth model as a 3D image. Therefore, the control unit 400 tracks the movement of the scaler and implements the movement of the scaler as a 3D image, and the display unit 200 outputs the movement of the scaler and the arch tooth model as a 3D image. can

The arch tooth model 100 is connected to the control unit 400, more specifically, to the signal receiver by a signal line 130, and the scaler 30 is also connected to the control unit 400 by a cable. . Of course, the arch tooth model and scaler may communicate with the control unit in a wireless manner.

The artificial calculus 20 may be provided for each artificial tooth in a predetermined shape and size according to each artificial tooth, and shape data of the artificial teeth may also be input to the memory 300 together with the shape data of the artificial teeth. there is.

The display unit 200 may output the removal state (removal process and final state) of the artificial calculus as an image, preferably a 3D image, and the final evaluation of the trajectory of the scaler tip and the removal status of the artificial calculus when scaling is completed The form of the result, for example, may be output in the form of a score and/or evaluation text, and an image, score, and/or evaluation result in the form of text may be output simultaneously or sequentially. In addition, the scaling procedure training device may sound an alarm when the scaler tip enters an unnecessary area.

In addition to the method exemplified above, a technology that detects the movement of objects, visualizes their relative positional relationship, movement, and shape in three dimensions (3D), and outputs it through a monitor is a game field, for example, virtual reality (VR) game technology. Since it is variously known in the field of 3D image processing, such as, the additional description of the technique of imaging the arch tooth model and the scaler by sensing the movement of the scaler is omitted, and the present invention provides such a motion detection and image output technology to the teeth It is characterized by being applied to the training of scaling procedures.
