DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an occlusal pressure diagnosing device for diagnosing the state of tooth occlusion using a occlusal pressure diagnosing sheet in which both surfaces of a pressure-sensitive sheet are covered with waterproof layers.

[0002]

2. Description of the Related Art In the field of dental care, carbon paper has been widely used for diagnosing the state of bite of a tooth. The carbon paper is inserted between the upper and lower teeth of the patient, and in this state, the patient strongly bites, thereby adhering carbon only to the portion where the upper and lower teeth contact. The dentist diagnoses the bite state of the patient from the position and area where the carbon adheres.

[0003]

However, the method using the carbon paper only detects that the upper and lower teeth are in contact, and cannot detect the pressure of the teeth, that is, the occlusal pressure. For this reason, the occlusal pressure must be predicted from the state of carbon adhesion, and the diagnosis of occlusal conditions such as strong or weak bite is likely to be inaccurate, making it difficult to determine the treatment policy correctly. there were.

Further, in order to clearly attach carbon to the portion where the tooth has touched, it is necessary to apply upper and lower teeth several times with ticks, or shift the jaw to the left and right to rub the carbon paper contact portion of the tooth with the tip of the tooth. Was necessary.

[0005] In addition, since the position where the tooth is in contact with the entire dental arch is unclear, the dentist must look into the oral cavity of the patient and work while checking the position of the carbon paper. For this reason, there was a problem that workability was poor.

Accordingly, the applicant has proposed using an occlusal force diagnostic sheet in which both surfaces of a pressure-sensitive sheet are covered with waterproof layers (Japanese Patent Application No. 4-302975). It has also been proposed to laminate a wax layer on at least one surface of the pressure-sensitive sheet and to copy the tooth pattern onto the wax layer so that the occlusal force and the occlusion state of the dental arch can be simultaneously diagnosed (Japanese Patent Application No. Hei 4-302976).
issue). Furthermore, it has been proposed that the occlusal force diagnostic sheet be read by a scanner and subjected to image processing by a computer to obtain a diagnostic result or various diagnostic materials (Japanese Patent Application No. Hei.
Nos. 302977 and 4-30297).

On the other hand, the occlusal force diagnostic sheet has a plurality of sizes depending on the size of the patient's mouth, and there is also a sheet having no wax layer and a sheet having a wax layer laminated on one side or both sides. As described above, there are a plurality of types of the occlusal force diagnostic sheet depending on the size, the presence or absence of the wax layer, and the like. For this reason, when performing computer processing, it is necessary to specify a range to be read by a scanner, or to specify the type of image processing depending on the presence or absence of a wax layer. Therefore, the operation was troublesome.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and reads an occlusal force diagnostic sheet in which both surfaces of a pressure-sensitive sheet are covered with waterproof layers with a scanner, performs image processing, and obtains diagnostic results and diagnostic materials. It is an object of the present invention to provide an occlusal force diagnostic apparatus that can eliminate the need to manually input the type of an occlusal force diagnostic sheet, the type of image processing, and the like when outputting, and can simplify the operation.

[0009]

According to the present invention, there is provided an occlusal force diagnostic apparatus for diagnosing an occlusal force by reading a tooth form recorded on an occlusal force diagnostic sheet in which both surfaces of a pressure-sensitive sheet are covered with waterproof layers. A holder fixed to the occlusal force diagnostic sheet and provided with a mark for discriminating the type of the occlusal force diagnostic sheet, a tooth pattern recorded on the occlusal force diagnostic sheet with the holder and a mark attached to the holder are read. A scanner, image processing means for performing predetermined image processing based on the mark, display means for displaying processing results by the image processing means, and a printer for printing out the image processing results. This is achieved by an occlusal force diagnostic device.

Here, the mark indicates, for example, the size of the occlusal force diagnostic sheet or the presence or absence of a wax layer. Here, an ID mark such as a patient's name may be used, and the content (for example, name) of the ID mark may be output to a display means or a printer. A mark indicating the density reference value may be used.

If the occlusal force diagnostic sheet is housed in a transparent cassette so that it can be attached to and detached from the scanner, positioning of the occlusal force diagnostic sheet is accurate and operability is good. If the display means, the scanner, and the printer are arranged so as to overlap in order from top to bottom, compactness and operability are improved. In this case, the occlusal force diagnostic sheet is set on the scanner with the anterior tooth side facing forward, the upper dental arch is displayed as a triangle on the upper display, and the lower dental arch is displayed on the lower part. It is desirable to display.

Furthermore, if the printer prints out on a transparent print sheet, it is easy to confirm the result of the treatment by superimposing and comparing the printout results before and after the treatment. This transparent printing paper includes not only paper but also a resin sheet such as a plastic film.

FIG. 1 is a plan view of an occlusal pressure diagnostic sheet used in the present invention, FIG. 2 is a sectional view showing its structure, FIG. 3 is an exploded view of a holder mounted on the sheet, and FIG. FIG. 5 is an illustration of the procedure, FIG.
FIG. 6 is a sectional view taken along line VI-VI in FIG. 5.

In FIG. 2, reference numeral 10 denotes a sheet-shaped synthetic resin support, for example, a 25 μm thick PET (polyethylene terephthalate) film.
Reference numeral 12 denotes a developer coating layer, which is formed by applying a solution obtained by dispersing an acid clay (montmorillonite) sulfuric acid-treated product in water containing caustic soda to one surface (surface) of the support 10 and drying the solution. is there.

Reference numeral 14 denotes a color-developing agent coating layer formed on the color-developing agent coating layer 12, which is formed by dissolving a color developing agent such as 1-phenyl-1-xylylethane in oil and microencapsulating it. is there. Here, the microcapsules are adjusted to various strengths, and the microcapsules to be destroyed change according to the pressure. When the microcapsules are destroyed by the pressure, the color developing agent therein is absorbed by the color developing agent together with the oil to form a color. In this embodiment, the color is red. The density of this color development increases almost linearly with increasing pressure.

As described above, the support 10 and the developer coating layer 1
A pressure-sensitive sheet 15 is formed by the color-developing agent coating layer 14 and the color-forming agent coating layer 14, and the pressure-sensitive sheet 15 is cut out in a substantially horseshoe shape as shown by a broken line in FIG. This shape is determined so as to substantially conform to the shape of a human dental arch, the outer peripheral edge may be approximately a horseshoe shape, and the inner concave cut may be omitted.

In FIG. 2, reference numeral 16 denotes a back waterproof layer,
It is formed of the same PET film as, for example, a 16 μm transparent film. An adhesive type paste is applied to one surface of the back waterproof layer 16 to form an adhesive layer 18. The back waterproof layer 16 is adhered to the back surface of the support 10 (the surface opposite to the developer application layer 12) by the adhesive layer 18.

Reference numeral 20 denotes a front waterproof layer, which is formed of a transparent PET film of 16 μm in the same manner as the back waterproof layer 16. The front waterproof layer 20 is overlaid on the color forming agent coating layer 14, and is adhered to the adhesive layer 18 of the back waterproof layer 16 along the outer periphery of the support 10. In this case, it is desirable that the pressure between the waterproof layers 16 and 20 be sufficiently reduced and evacuated.

As described above, the support 10, the developer coating layer 1
2. The laminated body 15 of the coloring agent coating layer 14 is
And glue the periphery along the outside of the horseshoe-shaped laminate 15. Then, the outer shape is cut out on the outer periphery of the laminated body 15 leaving a space where the waterproof layers 16 and 20 adhere to each other. As a result, a substantially horseshoe-shaped pressure-sensitive sheet 22 is formed. The pressure-sensitive sheet 22 is sealed with the back waterproof layer 16 and the front waterproof layer 20. For this reason, the water resistance is improved, and even if the saliva adheres in the oral cavity, there is no influence on the coloring property, and the reliability is increased.

Since one waterproof layer 16 is adhered to the back surface of the support 10, the back waterproof layer 16 does not peel off or move with respect to the support 10. Therefore, the front waterproof layer 20 whose periphery is fixed to the back waterproof layer 16 is
Will not move.

The horseshoe-shaped pressure-sensitive sheet 22 waterproofed by the waterproof layers 16 and 20 has a wax layer 24 on one side thereof.
Is formed. This wax layer 24 is made of, for example, 0.35 ± dental paraffin wax (JIS-T-6502).
It was uniformly applied to a thickness of 0.03 mm. The wax layer 24 is desirably colored in a color that is close to the color complementary to the color of the pressure-sensitive sheet 22. In this embodiment, a blue-green color is used.

On the surface of the wax layer 24, a transparent synthetic resin film 25 is further adhered. As the film 25, for example, a thin flexible film having a thickness of several μm, which is commercially available as a food packaging wrap film, can be used. The film 25 is usually obtained by adding a softener such as a fatty acid derivative, a stabilizer such as an epoxidized vegetable oil, or the like to a base material such as polyvinylidene chloride.

The film 25 adheres directly to the surface of the wax layer 24 and can be fixed by the adhesive force of the wax layer 24 itself. Note that the film 25 is formed so that its outer periphery is slightly inside the outer peripheral edge of the wax layer 24, and is desirably formed to have substantially the same outer shape as the pressure-sensitive sheet 22. In other words, the outer peripheral edge of the wax layer 24 projects slightly outward from the outer peripheral edges of the pressure-sensitive sheet 22 and the film 25. The occlusal force diagnostic sheet 26 is completed by attaching the film 25 to the wax layer 24 as described above.

The occlusal force diagnostic sheet 26 is fixed to a cardboard holder 28 as shown in FIG. As shown in FIG. 3, the holder 28 is formed by integrally forming an upper plate portion 30 and a lower plate portion 32 formed in a substantially Y-shape, and fold lines 34 provided on their base portions 30a and 32a. The upper plate portion 30 can be overlapped with the lower plate portion 32 by bending at.

The base 30 of the upper plate 30 and the lower plate 32
arm portions 30b, 32 branching bifurcated from a, 32a
“b” is curved substantially along the outer periphery of the occlusal force diagnostic sheet 26 in a substantially semicircular arc shape.

The holder 28 is fixed to the occlusal force diagnostic sheet 26 as shown in FIG. That is, the lower plate portion 32
The outer peripheral edge of the occlusal force diagnostic sheet 26 is positioned and placed on the arm 32b of the upper plate 30 and the upper plate 30 is
Wrap over. Then, the arm portion 30b of the upper plate portion 30 may be overlapped with the arm portion 32b of the lower plate portion 32 and pressed.

Since the wax layer 24 has appropriate flexibility and adhesiveness, when the peripheral edge of the occlusal force diagnostic sheet 26 is sandwiched between the arms 30b and 32b and pressed, the wax layer 24 flows. As shown in FIG. 6, both arms 30b, 32
b. As a result, the arms 30b and 32b are bonded to each other by the wax layer 24, and the holder 28 and the occlusal force diagnostic sheet 26 are integrated.

The occlusal force diagnostic sheet 26 is
8 is placed in the patient's open mouth by grasping the bases 30a and 32a, and is mounted so as to evenly hit the upper part of the maxillary dentition. When the patient gently bites, the pressure applied between the upper and lower teeth is applied to the wax layer 24 via the film 25, and the entire tooth profile of the dental arch is recorded as irregularities on the wax layer 24.

At this time, since the film 25 is thin and soft,
It is easily deformed following the tooth profile and does not affect the tooth profile formed on the wax layer 24. At the same time, the pressure applied between the upper and lower teeth is applied to the pressure-sensitive sheet 22, and only the portion where the pressure is applied develops a color according to the magnitude of the pressure. In this embodiment, the color is red.

FIG. 7 is a cross-sectional view of another occlusal force diagnostic sheet 26A, and FIG.
FIG. 6 is a cross-sectional view taken along a line corresponding to line VI-VI.

In this embodiment, the wax layers 24 and 24A are laminated on both sides of the pressure-sensitive sheet 22, and the films 25 and 25A are respectively adhered to the surfaces thereof. According to this embodiment, the meshing of the upper and lower dentitions can be separately recorded in the wax layers 24, 24A.

As described above, the occlusal force diagnostic sheet 26 (26A) in which the coloring at a density corresponding to the occlusal force is recorded on the pressure-sensitive sheet 22 and the tooth shape is recorded on the wax layer 24 (24A) is
The occlusal force is taken out from the patient's mouth, and occlusal force diagnosis is performed by the occlusal force diagnostic device according to the present invention.

FIG. 14 is an exploded perspective view of the cassette, FIG. 15 is a side view showing the internal structure of the scanner, FIG. 16 is an operation flowchart, and FIG. 17 is a view showing an example of print output.

Positioning small holes 36, 36 are formed in the base portions 30a, 32a of the holder 28 so as to fold along the folding line 34 and pass through the upper plate portion 30 and the lower plate portion 32 in an overlapped state. It is desirable that various marks 38 and 40 are provided on the bases 30a and 32a as shown in FIG. For example, if a cross-shaped mark 38 is provided in the vicinity of the confluence of the arm 30b and the base 30a of the upper plate 30 and the mark 38 is positioned near the center of the patient's front teeth, occlusal force diagnosis can be performed. It is possible to easily confirm the insertion position of the sheet 26 correctly. If an ID mark 40 for patient identification is added, it is convenient for organizing and managing the occlusal force diagnosis sheet 26 after the examination.

Further, the holder 28 may be provided with a bar code 42 as shown in FIG. 3, so that the dimensions and type of the sheet 26, the front and back, left and right, and the like can be automatically determined by a scanner 54 described later. . The density reference 44 may be added based on the reading characteristics of the scanner 54. Further, the date on which the diagnosis was performed may be added.

In FIG. 9, reference numeral 50 denotes a vertically long case, in which a CRT 52 as a display means is accommodated at the upper part, a scanner 54 is arranged under the CRT 52, and a printer 56 is accommodated at the lowermost part.
The scanner 54 and the printer 56 can be operated from the front of the housing 50. The scanner 54 has a pair of upper and lower color scanners 54A and 54B for reading images on both surfaces of the occlusal force diagnostic sheet 26 stored in a transparent cassette 58.

As shown in FIGS. 11 to 14, the cassette 58 includes a pair of upper and lower transparent plates 60 and 62 that can be opened and closed, and sandwiches the occlusal force diagnostic sheet 26 with the holder 28 therebetween. That is, a handle member 64 is fixed to one end of the lower transparent plate 62, and a hinge member 66 is fixed to the other end, and the upper transparent plate 60 is rotatably pivoted to the hinge member 66.

The lower transparent plate 62 is provided with positioning projections 68, 68 which are engaged with the positioning small holes 36, 36 provided in the holder 28. The holder 28 is positioned on the projections 68 and 68 and is held between the transparent plates 60 and 62. Here, the distance between the transparent plates 60 and 62 is set such that the sheet 26 can be held without crushing the tooth pattern recorded on the wax layer 24 (24A) of the occlusal force diagnostic sheet 26.

The cassette 58 is inserted into an insertion opening 70 of the scanner 54 which is opened on the front

It is guided to the first mirror box 72 and the second mirror box 74 through the transparent plates 60 and 62 of the cassette 58,
8 forms an image on the line sensor 80. By moving the first and second mirror boxes 72 and 74 in this manner, the images on both the upper and lower surfaces of the occlusal force diagnostic sheet 26 can be simultaneously read. This optical system has a large depth of focus, and can well read a tooth pattern having irregularities formed on the wax layer 24 of the occlusal force diagnostic sheet 26.

An image signal read by the line sensor 80 is read by a CPU 82 (FIG. 10) as image processing means.
After undergoing predetermined image processing, the image is stored in the memory 84. The content of this image processing is instructed from the keyboard 86. Then, the processing result is displayed on the CRT 52 and the printer 56
Is printed out. The printer 56 outputs an image on a transparent print sheet 88 by a thermal head 90.

The CPU 82 performs various spatial filtering processes such as an outline emphasis process and an averaging process on the image read by the scanner 54, and determines the pressure P with respect to the color density D of the pressure-sensitive sheet 22, that is, the occlusal force by a predetermined PD characteristic curve. Calculate using

The CPU 82 performs an arbitrary operation selected by the keyboard 86 from a plurality of types of operations. For example, the following calculation is performed. (1) Obtain the distribution of occlusal force. (2) Find the left, right, front and back balance of the occlusal force.
(3) Obtain the XY distribution of the occlusal force for each area partitioned by the XY axes. (4) The mountain whose height changes according to the magnitude of the occlusal force is drawn and its distribution is displayed three-dimensionally. (5) Find the center (center of gravity) of the occlusal force. (6) Find the average pressure of the occlusal force within a predetermined range, and so on.

Next, the operation of this embodiment will be described with reference to FIG. First, the occlusal force diagnostic sheet 26 bitten by the patient is set in the cassette 58, and is inserted into the insertion opening 70 of the scanner 54 with the upper surface of the upper jaw recorded thereon (step 1).
00). Then, the scanner 54 reads the ID mark 40 and other marks 42 and 44 (step 102). CPU8
In step 2, the name of the patient is read from the ID mark 40 and the like, and the size, type, diagnosis date, and the like of the sheet 26 are determined and recorded in the memory 84 (step 104).

The CPU 82 determines an image range to be read from the size of the sheet 26 (step 106). This range is scanned twice or once according to the presence or absence of the wax layer 24 (step 108). For example, the first scan of the surface with the wax layer 24
Is read, and an image indicating the occlusal force recorded on the pressure-sensitive sheet 22 by the second scan is read. The presence or absence of the wax layer 24 is indicated by mark 4.
2 to determine the type of the sheet 26.

The read image is subjected to appropriate image processing and stored in the memory 84 (step 110).

Next, the density of the color image is obtained (step 112). The pressure P, that is, the occlusal force, for this density D is obtained using the PD characteristic curve (step 114).
The obtained occlusal force is converted to a gradation corresponding to the magnitude of the pressure (step 116) and stored in the memory 84 (step 118).

Next, a desired operation mode is selected by the keyboard 86 (step 120). The operation of the selected mode is performed (step 122), and the result is output to the CRT 52 or the printer 56 (step 12).

As shown in FIG. 17, in the occlusal force distribution, the occlusal force of the upper dental arch is displayed in the upper row in the form of ∩, and the occlusal force of the lower dental arch is displayed in the form of the ∪ in the lower section. Is displayed. When the occlusal force diagnostic sheet 26 is set in the cassette 58 in the direction shown in FIG. 12 in this manner and inserted into the scanner 54 with the upper jaw recorded side facing up, the arrangement coincides with that when viewing the oral cavity of the patient. As a result, the occlusal force distribution of the upper and lower dental arches is displayed. For this reason, it is displayed with the same feeling as at the time of medical examination, and diagnosis is facilitated.

In FIG. 17, the occlusal force centers G are separately obtained for the upper jaw and the lower jaw, and are indicated by G _U and _GL , respectively. Also, the name N of the patient read from the ID mark 40, the diagnosis date read from another mark, and the like are displayed. Further, a color density scale S is displayed based on the read density reference 44.

[0052]

As described above, according to the first aspect of the present invention, the holder fixed to the occlusal force diagnostic sheet is marked with a mark,
The type of the occlusal force diagnostic sheet is determined by reading this mark with a scanner, so the type of the sheet can be reliably determined without manually inputting the type of the sheet, and the content of image processing can be determined automatically, reducing the number of manual operations. Operation can be simplified.

If the image range to be read is determined based on the mark, it is not necessary to read an unnecessary image range or perform image processing, so that noise is reduced and the processing speed is increased (claim 2). If the mark indicates the presence or absence of the wax layer, processing corresponding to the presence or absence of the wax layer can be performed automatically (claim 3). If the ID mark of the patient is attached to the holder and the contents are output, there is no possibility that the output result is mistaken for the patient (claim 4). If a mark (density reference) indicating the density reference value is attached to the holder, the occlusal force can be more accurately determined by the density determination (claim 5).

If the occlusal force diagnostic sheet is housed in a transparent cassette so that it can be attached to and detached from the scanner from the front, even if the sheet is bent or deformed by being bitten by the teeth, the curvature or deformation is corrected by the cassette. The image can be read while being held flat. Therefore, the reading of the image becomes accurate (claim 6).

If the display means is placed above and the scanner and the printer are arranged in that order, it is easy to operate them from the front, and these are convenient and do not hinder each other. The sheet is set on the scanner with the front teeth facing forward, and the upper part of the dental arch is displayed on the display means and the printer with the upper dental arch facing the lower part and the lower dental arch is displayed facing the lower part. If this is the case, the arrangement will be similar to the arrangement used when observing the inside of the oral cavity of the patient, and the diagnosis will be easier (claim 8).

Furthermore, if the printer prints out on a transparent print sheet, the effect of the treatment can be easily compared and confirmed by superimposing the output results before and after the treatment (claim 9). .
