Description

Method for taking edentulous impressions and tray complex therefor}

The present invention relates to a technique for taking an impression of a patient and manufacturing a complete denture.

In general, a patient visits the dentist at least five times for the fabrication of a full denture. Among them, more than 3 visits are required for basic work for taking impressions and fabricating complete dentures. When the patient visits the hospital for the first time, a preliminary impression body is obtained using a ready-made tray, and a patient-customized personal tray is manufactured with the obtained preliminary impression body. When the patient visits the hospital for the second time, a precise impression of the patient's oral cavity is taken using an individual tray. When the dental office sends a precision impression to a laboratory, the laboratory creates a model by pouring gypsum into the precision impression, and manufactures a record base and wax rim. Then, at the patient's third visit, wax cream is tried on in the patient's oral cavity, and a baseline for making a complete denture is identified.

Due to the increase in the number of visits, there is a problem in that the manufacturing schedule of complete dentures becomes longer. In addition, an error may occur in the process of injecting gypsum into the impression body. Due to this, an error may occur between the record base and the wax frame working based on the gypsum model.

Korean Registered Patent No. 10-1302702 (registered on August 27, 2013)

According to an embodiment, the shape and size of the tray are classified so that a precise impression body can be taken without a preliminary impression process, and an impression is made by using a tray composite in which an articulating agent is combined with the tray to eliminate the labor work of manufacturing a gypsum model. We propose a method for taking an edentulous impression and a composite tray for it.

An edentulous impression taking method according to an embodiment includes the steps of selecting an upper tray and a lower tray corresponding to the size of a patient's arch, selecting an upper and lower articulator corresponding to the height of the patient's vertical dimension, and selecting the upper and lower articulation materials. The method may include combining the tray and the upper articulating agent, and the selected lower tray and the lower articulating agent, respectively, and performing impression taking and vertical dimension taking using the combined tray and the articulating agent.

The performing of the impression taking and the vertical height taking may include taking an impression body by binding the upper and lower articulation materials to binding parts respectively formed on the upper and lower trays.

The step of performing the impression taking and the vertical dimension measurement may include softening the occlusion marker by applying heat to the occlusion marker formed on the upper part of the mandibular articulator and obtaining the vertical dimension so as to enable precise vertical dimension acquisition.

In the step of obtaining the vertical dimension, the vertical dimension may be obtained by contacting the occlusal markers of the upper articulation material and the softened mandibular articulation material.

The edentulous impression taking method may further include a step of confirming the degree of support of the upper lip of the face using a change in the upper lip according to the thickness of the maxillary articulator.

The method for taking an edentulous impression may further include, when taking an impression of the upper jaw, determining standards for a horizontal position and a vertical height using the maxillary articulator.

The method for taking an edentulous impression involves acquiring impression data by scanning the impression body, acquiring vertical dimension scan data by scanning the vertical dimension in the patient's mouth, and scanning the movement of the lower jaw by scanning the movement of the lower jaw in the patient's mouth. The method may further include obtaining data and matching scan data.

The step of acquiring the vertical dimension scan data is after obtaining the vertical dimension, scanning the scan marker of the articulation material in a static state of the patient to acquire the vertical dimension scan data, and the step of acquiring the mandibular movement scan data is after obtaining the vertical dimension, Mandibular motion scan data may be acquired by scanning the scan marker of the articulation agent in the patient's mandibular motion state.

The step of matching each scan data may include matching impression body scan data and vertical dimension scan data, and matching vertical dimension scan data and lower jaw motion scan data.

In the step of matching each scan data, the impression body scan data and the vertical dimension scan data may be matched by matching the scan marker of the articulator when scanning the impression body and the scan marker of the articulator when scanning the vertical dimension and mandible movement. .

An edentulous impression taking system according to another embodiment selects an upper tray and a lower tray corresponding to the size of the patient's arch, selects an upper and lower articulator corresponding to the height of the patient's vertical dimension, selects the selected upper tray and The upper articulating agent, the selected lower tray and the lower articulating agent are combined, respectively, and impression taking and vertical dimension taking can be performed using the combined tray and articulating agent.

A tray composite according to another embodiment includes an upper tray and a lower tray having a size corresponding to the size of the patient's arch and including a predetermined attachment portion, and an upper tray having a height corresponding to the height of the patient's vertical diameter through the attachment portion. and an upper articulating agent and a lower articulating agent coupled to the lower tray.

An upper jaw scan marker for obtaining the patient's vertical dimension may be formed on the upper articulation material, and a lower jaw scan marker may be formed on the lower jaw articulation material for obtaining the patient's vertical dimension or mandibular movement.

An occlusal marker softened by heat is further formed on the upper part of the mandibular articulation material, and the occlusal marker of the upper articulation material and the softened mandibular articulation material come into contact with each other so that a vertical dimension can be obtained.

A space for accommodating impression materials used for taking a patient's impression and a hole for discharging surplus impression materials may be formed in the upper tray and the lower tray, respectively.

According to the edentulous impression taking method and tray composite therefor according to an embodiment, a tray corresponding to the shape and size of the patient's arch is selected, and an articulation material corresponding to the height is selected in consideration of the vertical dimension of the patient, and then each selected tray is selected. Since the tray composite is formed by combining the and the occlusal, and impression taking and vertical dimension can be taken at the same time using the tray composite, the number of patient visits to the dentist can be reduced from 3 times to 1 time. In addition, since the vertical dimension and mandibular motion are directly scanned in the patient's mouth and the data are transmitted to the software, errors can be reduced compared to mandibular motion reproduced with an analog articulator.

As the patient's occlusion data is transferred to the software, it will be helpful for future artificial tooth arrangement and occlusion adjustment. For example, an occlusion suitable for a patient may be assigned after arranging the artificial teeth using the patient's occlusion data.

The embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art.

1 is a diagram showing the configuration of an edentulous impression taking system according to an embodiment of the present invention.

Referring to FIG. 1 , the edentulous impression taking system 1 for taking an edentulous impression intends to perform all of the impression taking and vertical dimension measurement steps performed over at least three visits in the prior art in one visit. For example, after selecting a tray corresponding to the shape and size of the patient's arch, an impression is taken by selecting the height of the occlusal material suitable for the vertical diameter of the face. By doing so, it is possible to popularize vertical dimension setting and mandibular exercise simultaneously with impression taking, and reduce the number of visits by patients, thereby shortening the total denture manufacturing period.

The edentulous impression taking system 1 may be performed through a physical device or through software. When performed on software, the edentulous impression taking system 1 acquires the patient's clinical data and performs simulation through diagnosis and analysis using the clinical data through control by the software to establish a treatment plan. The edentulous impression taking system 1 may select a tray for taking an edentulous impression, acquire impression data and registration data of the patient using the selected tray, and then fabricate a complete denture using the impression data and registration data. there is.

Referring to FIG. 1 , an edentulous impression taking system 1 according to an embodiment includes a data acquisition unit 10, a storage unit 12, a control unit 14, an input unit 16, and an output unit 18. .

The data acquisition unit 10 acquires dental image data from teeth including damaged teeth of the patient. Dental image data includes, for example, scan data of a patient, and the scan data includes impression body scan data, vertical dimension scan data, mandibular motion scan data, and the like.

The storage unit 12 stores various data such as information necessary for the operation of the edentulous impression taking system 1 and information generated according to the operation. Scan data of individual patients is stored in the storage unit 12 according to an embodiment, and may be provided to the control unit 14 according to a user's request. At this time, images of the upper and lower jaws of individual patients are stored in the storage unit 12 , and data including scan data of a specific patient may be provided to the control unit 14 according to a user's request.

The controller 14 performs edentulous impression taking. At this time, it is possible to control each functional unit while establishing a plan for treatment through control by a computer program. The control unit 14 manages the screen information displayed on the screen through the output unit 18, and establishes a treatment plan by performing simulation through diagnosis and analysis using dental images through control by software.

The controller 14 or the edentulous impression taking system 1 according to an embodiment determines a tray for taking an edentulous impression. At this time, the tray and the articulation agent are separated, a tray corresponding to the size and shape of the patient's arch is selected, an articulation agent corresponding to the vertical height and arch shape of the patient is selected, and then the articulation agent is combined with each selected tray. . Tray selection methods include a method of selecting a tray corresponding to the size and shape of the patient's dental arch from among a plurality of ready-made trays, a method of designing a tray corresponding to the size and shape of the patient's dental arch, and then outputting the tray with a 3D printer.

By combining the tray and the occlusal, it is possible to perform impression taking and vertical dimension taking at the same time. For example, an impression body of a patient may be taken by a closed mouth impression method by binding an articulation material to a binding portion of the upper portion of the tray. In addition, the degree of lip support of the patient and the harmony with the face can be confirmed through the occlusal of the upper jaw. In addition, in order to accurately measure the vertical dimension of the patient, the occlusion marker (eg, cone shape) formed on the upper part of the mandibular articulator is softened by slightly heating to obtain the vertical dimension, and in this state, the patient's lower jaw movement to do it In addition, heat is applied to the occlusal marker formed on the upper part of the mandibular articulation material to soften it, and a vertical diameter is obtained, and the upper articulator and the softened mandibular articulation material come into contact with each other, so that a precise vertical diameter can be obtained.

Here, the occlusal agent may be a material such as plastic, resin, or wax rim, and the occlusal marker may be made of a material such as a soft material or a thermoplastic material, but is not limited thereto. In addition, although the present invention has been described assuming that the occlusion marker has a cone shape, it may be formed in various shapes such as a cylinder or a polygonal block as well as a cone.

On the other hand, a scan marker may be formed in the articulation material including an anterior and posterior part of the articulation material in order to read the vertical dimension and mandibular motion with a scanner. The edentulous impression acquisition system (1) acquires vertical dimension scan data by scanning the scan marker of the articulation material in a static state after obtaining the vertical dimension, and scans the dynamic scan marker during mandibular movement to obtain mandibular movement scan data. can be obtained By matching these scan markers, the impression body scan data and vertical height scan data may be matched, and the vertical height scan data and mandibular motion scan data may be matched.

In addition, the control unit 14 or the edentulous impression taking system 1 may fabricate a complete denture using the impression data obtained from the patient, the acquired vertical height data, and the mandibular motion scan data.

Meanwhile, the input unit 16 receives a user manipulation signal through a user interface. For example, the input unit 16 receives a user manipulation signal such as a mouse click from a dental image displayed as a virtual graphic object on a screen through the output unit 18 .

In addition, the output unit 18 displays the dental image on the screen, and displays the simulation process through the control unit 14 on the screen. Furthermore, the denture or tray designed through the control unit 14 can be output through a 3D printer.

2 is a diagram showing the flow of an edentulous impression taking method according to an embodiment of the present invention.

Referring to FIGS. 1 and 2 , the edentulous impression taking system 1 selects the size and shape of the tray in consideration of the size of the patient's arch (S210). For example, depending on the size of the patient's arch, the size of the tray can be selected from Small (S), Medium (M), and Large (L) sizes. An example of tray size selection according to the size of the dental arch will be described later with reference to FIGS. 3 and 4 .

Next, the edentulous impression taking system 1 selects the height of the occlusal material in consideration of the patient's vertical dimension and arch shape (S220). For example, the height of the articulation material may be classified into S, M, L, and the like according to the difference in vertical dimension of the patient. To this end, when the patient is in a rest position, the lengths of the tip of the nose and the tip of the chin are measured. Even when the patient bites down on the articulation material, an appropriate articulation material height is selected so as to match the length of the vertical diameter in this state. In general, the maxilla from the border to the tip of the articulator is about 20 mm. Considering the height of the tray, the height of the maxillary articulator can be selected, for example, S: 5 to 7 mm, M: 7 to 9 mm, L: 9 to 11 mm, and the like. In the case of the lower jaw, considering the height of the cone (for example, 5mm) of the upper part of the articulating material, the height of the mandibular articulation material is set to S: 2 ~ 4mm, M: 4 ~ 6mm, L: 6 ~ 8mm, etc. You can choose. However, this is only an example to help understanding of the present invention, and the selection of the height of the articulating material is not limited thereto.

Subsequently, the edentulous impression taking system 1 combines the selected trays and the articulating agent (S230). A binding portion on the top of the tray may be used to bind the articulating agent to the tray. An example of a binding unit that couples the articulating agent to the tray will be described later with reference to FIGS. 3 and 4 . The bonding state of the tray and the articulating agent will be described later with reference to FIG. 6 .

Next, the edentulous impression taking system 1 takes an impression body by the closed mouth impression method using the combined tray (S240). For example, an impression body of a patient is taken by a closed mouth impression method by binding an articulation material to a binding portion of an upper portion of the tray. The acquired impression body may be transferred to software after scanning. The closed mouth impression is a method in which the upper jaw impression body is taken first, and then the lower jaw impression body is taken.

Subsequently, the edentulous impression acquisition system 1 acquires a precise vertical height (S250). In order to obtain the vertical dimension, heat is applied to the occlusal marker in the form of a cone formed on the upper part of the mandibular articulation material to soften it, and the vertical dimension can be obtained. For example, the cone of the mandibular articulation material is softened to obtain a precise vertical dimension. As the softened cone comes into contact with the occlusal surface of the maxillary articulation material, the length of the cone decreases, and the patient's own centric relation occlusion state becomes popular. Adjust the vertical height of the cone and ask the patient to do deglutition movement. During swallowing exercise, the mandible becomes in a rest position, and a precise vertical dimension can be obtained. The height of the cone may be 4 mm to 6 mm, but is not limited thereto.

Subsequently, the edentulous impression acquisition system 1 acquires vertical dimension scan data by scanning the vertical dimension in order to transfer the acquired vertical dimension of the patient to the software (S260). To this end, a scan marker is formed on the upper portion of the articulating material. For example, vertical dimension scan data can be obtained by scanning a scan marker portion composed of three points (one point in the anterior region and two points in the posterior region) of the upper and lower articulation materials in a state in which the upper and lower jaws are bitten. The vertical height scan data is passed to the software.

Next, the edentulous impression acquisition system 1 acquires mandibular motion scan data by scanning the dynamic motion of the mandible in order to reproduce the mandibular motion following the vertical height on the software (S270). Similar to vertical height scanning, mandibular movement scan data can be obtained by scanning a scan marker composed of 3 mandibular articulator points (1 point in the anterior region, 2 points in the posterior region) during mandibular movement.

Subsequently, the edentulous impression acquisition system 1 transmits the impression body scan data to software, and matches the vertical height scan data with the mandibular motion scan data (S280). As an impression body scanning method, there is a method of injecting impression material into a tray to obtain an impression of a patient and then scanning the impression body as it is. The registration criterion matches the scan marker of the articulator when scanning the impression body and the scan marker of the articulator when scanning the vertical dimension and mandibular movement. By matching impression body and vertical dimension scan data, occlusal plane, maxillary and mandibular height, and artificial tooth arrangement information can be obtained in software, and mandibular movement of completed complete dentures can be reproduced by matching vertical dimension scan data and mandibular movement scan data. there is.

That is, the patient's upper jaw impression body is first taken with the upper jaw tray 30 , and at this time, the horizontal position and vertical height of the upper jaw articulation material 70 may be determined. For example, the maxillary articulator 70 is parallel to the pupillary line from the front so that there is no tilting of the maxillary articulator 70, and the maxillary articulator 70 is the campus line (Camper's line) from the side. ) and determine the position of the horizontal line of the maxillary articulator 70. In addition, the vertical height of the maxillary articulator 70 is determined according to the height of the maxillary articulator 70 based on the height descending downward by about 1 to 2 mm centered on the upper lip during impression taking. .

On the other hand, the degree of upper lip support of the face can be grasped using the change in the upper lip according to the thickness of the upper lip articulation material 70, and if the degree of upper lip support needs to be adjusted, the outer part of the upper lip articulation material 70 can be trimmed. .
