In dental treatment, the exact positional relationship between the maxillary and mandibular arches centered on the jaw joint and the occlusion formed by interlocking the upper and lower teeth in all processes ranging from diagnosis of the patient's condition to treatment and periodic check-up Accurate information is very important.

In particular, it is more helpful when manufacturing a prosthesis used for dental treatment.If the information related to the relative positional relationship and occlusion of the upper/mandibular arch can be obtained accurately, the accuracy in the manufacturing process of the prosthesis will increase, and subsequent dental treatment will be smooth. In addition, it is possible to more easily solve the occlusal problem that may occur in the natural dentition.

However, in the case of all restoration treatments performed by dentistry until recently, for example, filling after removing the cavities or restoring the lost tooth with an artificial prosthesis, the exact position, distance, and motion of the upper and lower arches for each patient. Because it was difficult to measure, it was difficult to use this information in the process of making a dental prosthesis, so in the case of fabrication of a dental prosthesis or treatment using a dental prosthesis, the approximate positional relationship between the upper and lower arches was used. In addition, since the approximate positional relationship between the upper and lower arches had to be used, it was even more difficult to link them to the occlusion, and the situation was to rely only on the senses and experiences of the dentist or dental technician.

As a conventionally known equipment for measuring motion state data between the upper and lower arches, there is an equipment called Arcus digma manufactured by KaVo, Germany, but Arcus digma is an expensive equipment and the device itself is complex, so it is difficult to use it in general dental sites.

The infrared sensor is a type of distance measuring sensor used to measure the distance between the sensor and an object. After the infrared sensor transmits infrared light to the object, it measures the time reflected on the object and re-incidents to the sensor. By multiplying the speed and time, you can measure the distance between the infrared sensor and the object.

As shown in FIG. 1, the target to which the infrared sensor included in the attachment sensor 200 transmits infrared rays may be a screen 400 located in front of the patient's face.

Hereinafter, a detailed description will be given of a process of measuring the motion information of the patient's upper and lower jaw and the sagittal angle, lateral condyle angle, and anterior induction angle, which have a dental meaning when moving the upper and lower jaw of the patient. First, the sagittal plane, coronal plane, and horizontal plane referred to in anatomy will be described first in order to explain the above-described sagittal condylar angle, lateral condylar angle, and anterior guidance angle.

3 shows the sagittal plane 10, the coronal plane 20, and the horizontal plane 30 based on the human body. As shown in Fig. 3, when the axis extending in the anteroposterior direction of the body is the X axis, the axis extending in the left and right direction of the body is the Y axis, and the axis extending in the vertical direction is the axis, the sagittal plane 10 is an XZ plane, The tubular surface 20 refers to the YZ plane, and the horizontal plane 30 refers to the XY plane.

4 is a detailed diagram illustrating a process of measuring a condylar guidance angle of a patient using the first embodiment of the present invention. The movement to open the mandible while the patient's maxilla and mandible are closed, that is, the movement to open the jaw, is called an anterior movement of the mandible, and the sagittal path refers to the path of movement of the condyle when the patient moves the mandible forward. The angle refers to the angle between the sagittal path and the horizontal plane 30.

The condyle can be seen as a part of the mandible adjacent to the point where the attachment sensors 200a and 200a' are attached in FIG. 2, but the attachment sensors 200a and 200a' themselves are attached to the patient's face and cannot be directly attached to the condyle. Therefore, it is not possible to accurately measure the sagittal condyle during anterior movement of the mandible using only the motion information of the attachment sensors 200a and 200a'.

The present invention uses the following method to solve the above problems. First, as shown in FIG. 4, the horizontal plane 30 is set based on the attachment sensor 200a installed on one side of the center of the migration and the attachment sensor 200b attached to the lower boundary B of the flyover, and the horizontal plane 30 ) Is moved downward to set the first horizontal surface 31 in the attachment sensor 200c attached to the jaw. At this time, the attachment sensor 200c may store information on how much the first horizontal surface 31 is rotated with respect to the Y-axis while the first horizontal surface 31 is set, and the stored information is the attachment sensor 200c or the recording unit 300 Can be stored in. Thereafter, when the patient performs the forward movement of the mandible to open the jaw, the attachment sensor 200c moves along the jaw and rotates about a certain degree based on the Y-axis. The attachment sensor 200c uses the built-in 9-axis sensor to measure how much the attachment sensor 200c has rotated after the forward movement of the mandible with respect to the Y-axis, and the first inclined plane based on the rotated attachment sensor 200c. (32) is set, and the recording unit 300 measures the angle between the first horizontal surface 31 and the first inclined surface 32 to obtain the sagittal condylar angle.

The obtained sagittal angle is stored in the recording unit 300, and motion information (trajectory information) of each attachment sensor may also be stored in the recording unit 300 in the process of obtaining the sagittal angle.

5 is a diagram illustrating a process of obtaining a lateral guidance angle (Bennet angle) using the first embodiment of the present invention. When the patient moves the mandible laterally with the maxilla and mandible closed, the working condyle (the direction of movement and the ipsilateral condyle) 40 only generates a small amount of rotational motion, but the non-working condyle (the condyle opposite the direction of movement) (41 ) Moves inwardly, and the angle between the anterior trajectory and the lateral motion trajectory of the condyle is called the lateral condylar angle. To measure the lateral condylar angle, the patient moves the mandible to the left or right while the upper and lower teeth are in contact with each other, and the mandibular canine (canine) in the direction of movement is placed on the end of the canine occlusal surface of the maxillary tooth. Let it move until it touches.

The lateral condylar angle is also measured using the attachment sensor 200c attached to the jaw because the sensor cannot be directly attached to the condyle like the sagittal condyle. That is, as shown in FIG. 5, the sagittal plane 10 is set based on the attachment sensor 200a at the center A of the migration. At this time, the attachment sensor (c) may store information on how much the first sagittal plane 11 is rotated with respect to the Z axis, and the stored information is the attachment sensor 200c or the recording unit 300 ) Can be stored. Thereafter, when the patient performs a lateral movement of the mandible, the attachment sensor 200c rotates horizontally about the Z-axis by a certain degree while moving along the jaw. The attachment sensor 200c uses the built-in 9-axis sensor to measure how much the attachment sensor 200c has rotated after the forward movement of the mandible with respect to the Z-axis, and the second slope based on the rotated attachment sensor 200c. After setting (12), the recording unit 300 measures the angle between the first sagittal plane 11 and the second inclined plane 12 to obtain a lateral condylar angle.

The lateral condylar angle obtained through the above-described process is stored in the recording unit 300, and motion information (trajectory information) of each attachment sensor may also be stored in the recording unit 300 in the process of obtaining the sagittal condylar angle. .

6 is a detailed illustration of a process of measuring an anterior guidance angle using the first embodiment of the present invention. The anterior guidance angle refers to the guidance angle generated by the contact between the tongue of the maxillary anterior teeth and the incisors of the mandibular anterior teeth during the anterior guidance of the mandible. In order to measure the anterior induction angle, the mandible is moved forward while the teeth are in contact with the teeth in contact with the upper and lower teeth as a reference, and the mandibular anterior cut surface is moved until it touches the upper and lower anterior cut, and the resulting angle is measured. That is, after moving the cut surface of the mandibular anterior teeth in FIG. 6 from E1 to E2, the degree of rotation of the attachment sensor attached to the jaw based on the Y-axis to set the third inclined plane, and the angle between the third inclined plane and the horizontal plane The forward induction angle can be obtained by measuring.

The information on the sagittal, lateral and anterior induction angles obtained in the above-described process, and the motion information of each attachment sensor are stored in the recording unit 300 to be used in the patient's treatment process or used to manufacture a dental prosthesis. .

[Second Example]

As described above, the recording conversion system including the mandibular motion detection sensor according to the present invention can be used in manufacturing a prosthesis, and a second embodiment of the present invention for manufacturing a prosthesis will be described below.

The recording conversion system including the mandibular motion detection sensor according to the second embodiment of the present invention includes a depth sensor, an attachment sensor, and a recording unit included in the first embodiment of the present invention, as well as the tray 500 shown in FIGS. 7 and 8. It may further include.

The tray 500 is inserted into the oral cavity of an edentulous patient and used to obtain the shape of the gum, and the tray 500 may be composed of a maxillary tray 600, a guide plate 700, and a mandibular tray 800. .

The maxillary tray 600 and the mandibular tray 800 shown in FIGS. 7 and 8 remove the configuration of the handle included in the conventional edentulous tray, and after the tray 500 is inserted into the patient's oral cavity, the mouth is closed. So that the shape of the patient's gums, the position where the patient closes the mouth (CR, Centric Relation, center of gravity), the height at which the patient closes the mouth (VD, Vertical Dimension, vertical diameter), and the position of the maxillary anterior teeth can be obtained. There is an advantage. At this time, the shape of the gum includes the shape of the patient's gums and the tissues in the oral cavity including information for manufacturing the edentulous patient's total dentures. Since each patient has a different shape of the gum or oral cavity, the tray By applying the impression material to 500, it is possible to perform impression taking after modeling the shape of the patient's maxillary/mandibular gums.

The maxillary tray 600 is inserted into the patient's maxillary gums on the upper surface 610 and forms a receiving space 611 in which the impression material is accommodated, and a plurality of coupling protrusions 621 protruding downward from the lower surface 620 are provided. Can be formed. The impression material accommodated in the receiving space 611 is a material used to perform various dental procedures and is made of an impression compound, wax and gypsum, alginate, resin, or rubber-type impression material, which deviates from the gist of the present invention. Without being accommodated in the receiving space 611 of the upper jaw tray 600, it can be transformed into any material for obtaining the shape of the gum. In addition, it is preferable that the upper surface of the maxillary tray 600 is formed to be similar to the shape of the maxillary gum in order to be fitted in correspondence with the maxillary gum of the patient.

The guide plate 700 is coupled to the lower portion of the maxillary tray 600 to obtain a position (CR) where the patient closes the mouth and the position of the maxillary anterior teeth, and is provided on the upper surface 710 of the guide plate 700. A plurality of coupling grooves 721 corresponding to and coupling with the coupling protrusion 621 of 600) may be formed to be coupled to the lower portion of the upper jaw tray 600.

In addition, the coupling groove 721 of the guide plate 700 is formed to have a larger diameter than the coupling projection 621 of the upper jaw tray so that the coupling protrusion 621 of the upper jaw tray 600 is fitted, and forms a movable clearance. , It is possible to obtain the shape of the gum according to the coupling position of the upper jaw tray 600 and the guide plate 700.

At this time, after setting the position of the upper anterior teeth of the patient and the position and height of the patient's mouth when the patient's mouth is closed by slightly moving the guide plate 200 vertically, the receiving space 611 of the upper jaw tray 600 And by applying an impression material to the space between the upper jaw tray 600 and the guide plate 700 and the clearance between the coupling protrusion 621 and the coupling groove 711, the upper jaw tray 600 and the guide plate 700 Can be fixed.

At this time, in the past, since adjustment after fixing of the upper and lower gums fixed by the impression material cannot be considered, the intermaxillary relationship of the upper and lower gums cannot be obtained. After formation, a wax rim was made and the patient came to the hospital again, and the intermaxillary relationship between the patient's upper and lower gums was obtained. However, the tray 500 of the present invention is fixed to the patient's maxillary gum by accommodating the impression material so as to be fixed to the patient's maxillary gum in the receiving space 611, as in the above configuration, As the guide plate 700 coupled with the coupling protrusion 621 from the lower portion of the maxillary tray 600 can be moved and adjusted, after fixing the maxillary tray 600, the maxillary tray 600 and the guide There is an advantage in that the shape of the patient's gums can be obtained according to the joint position of the plate 700. After that, the mandibular tray 800 is fixed and the upper and lower trays are inserted into the patient's mouth, There is an advantage in that it is possible to acquire an intermaxillary relationship between the mandibular gums.

9 and 10 are side and front views of a tray 500 according to a second embodiment of the present invention.

Referring to FIGS. 9 and 10, the mandibular tray 800 is described in detail, and the mandibular tray 800 is for acquiring the shape of the mandibular gum by being inserted into the mandibular gum of the patient. A receiving space 821 that is inserted and accommodates the impression material is formed, and is provided in the center of the front of the upper surface 810 and protrudes upward to obtain a height measuring protrusion for obtaining the shape of the gum according to the vertical height (VD) ( 811) may be included.

The vertical height (VD) refers to the space where the teeth are located between the upper and lower jaws of the patient, and the vertical height (VD) is calculated by measuring the height of the height measuring protrusion 811 of the mandibular tray 800 in the present invention. It can be, if necessary, it is possible to adjust the height by cutting the height measuring protrusion 811.

The lower tray 800 is located at the rear of the height measuring protrusion 811, and further includes a pressing protrusion 812 for protruding upward from the upper surface 810 to obtain the shape of the patient's maxillary gum, and the pressing protrusion ( The lower portion of the pressure protrusion 812 may be formed with a pressure protrusion groove 813 that is recessed by a predetermined height into the inner side of the pressure protrusion 812.

The pressure protrusion groove 813 is formed to extend from the upper surface 810, and must be formed so as not to penetrate the upper surface of the four pressure protrusion 812, and is formed around the molar position of the tooth in order to imitate the teeth where the upper and lower jaws contact. It is desirable. In addition, it is possible to more firmly fix the upper jaw tray 600 and the guide plate 700 by applying an impression material to the pressing protrusion groove 813 after acquiring the intermaxillary relationship of the lower jaw tray 300.

At this time, in the case of mandibular impression acquisition for obtaining the shape of the patient's mandibular gum, the mandibular tray 800 is fixed to the mandibular gum by using a modeling compound in the receiving space 821 of the lower surface 820, and the mandibular tray ( 800) After applying an impression material to the pressure protrusion 812 of the upper surface 810, the patient closes the mouth, and after appropriately setting the anteroposterior position of the mark generated by pressing the pressure protrusion 812 by the upper jaw, it is fixed using a resin. I can.

Thereafter, by setting the intermaxillary relationship between the upper jaw tray 600 and the guide plate 700 and applying an impression material, it is possible to perform an impression of the patient.

9 and 10, the position of the maxillary anterior teeth is obtained using the position of the front end surface 731 of the guide plate 700, and the height of the height measuring protrusion 811 of the lower tray 800 is The vertical height (VD) is obtained by using, and the center position (CR) may be obtained through a position where the height measuring protrusion 811 abuts the lower surface 720 of the guide plate 700. In more detail, the center position (CR) is adjusted so that the center of the front end surface 731 of the guide plate 700 and the center of the height measuring protrusion 811 of the lower jaw tray 800 coincide with each other to perform impression It is preferable to do this, and at this time, it is a position in which the lower surface 720 of the guide plate 700 and the height measuring protrusion 811 of the lower jaw tray 800 abut, and a position where the upper and the lower jaw of the patient are engaged can be obtained. .

The mandibular tray 800 may be formed in a horseshoe shape with one side open in a shape similar to a patient's oral cavity so as to be fitted to the patient's mandibular gums. At this time, both end portions of the mandibular tray 800 are formed to open a portion corresponding to a position where the maxillary gum and the mandibular gum located at the end of the patient's oral cavity are opened, and when the patient closes the mouth, the mandibular tray ( 800) is preferably formed so as not to be caught. The present invention does not have the shape of the open mandible tray as described above, so when the patient closes his mouth to obtain the central position (CR) of the maxillary and mandible, both ends of the mandibular tray 800 are caught on the maxillary gums and make an accurate impression. The disadvantage of not being able to perform acquisition was solved.

In the tray 500 of the present invention according to the above configuration, in order to solve the problem of not acquiring the intermaxillary relationship between the maxilla and the mandible due to the configuration of the conventional handle, the conventional handle is removed, and the maxillary tray 600 is By providing the guide plate 700 coupled to the lower part, all information for manufacturing the total dentures of the edentulous patient by simultaneously performing the impression of the patient's upper and lower jaws and obtaining the shape of the gums according to the position where the patient closes the mouth There is an advantage in that it can be obtained at one time, and this has the advantage of having more economical and high accuracy by reducing the number of visits that a patient visits several times to take an impression.

In order to measure the maxillofacial system according to the patient's mandibular motion using the tray 500 and use it to manufacture the patient's prosthesis, at least one attachment sensor is inserted into the tray 500 into the patient's oral cavity. Can be attached.
