DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a tooth modification device of the present invention
The description will be made based on the embodiment or the modification shown in FIGS. [Configuration of Embodiment] The first embodiment proposes use as a tooth modification device. FIG. 1 is a block diagram of a tooth modification device according to a first embodiment, and is a schematic diagram of a tooth modification device of a tooth and a schematic cross-sectional view of a tooth having a tooth modification agent applied to the surface.

The tooth shown in FIG. 1 is dentin such as when dentin is exposed on the tooth surface. In many cases, the presence of dental pulp causes hypersensitivity or the like, and the tooth is susceptible to dental caries and wear. It is used to irradiate the site with electromagnetic waves to reinforce the surface layer of dentin or the inside of the surface. The tooth modification apparatus for teeth includes first and second electromagnetic wave irradiation means 3 and 4 for irradiating electromagnetic waves. The first electromagnetic wave irradiating means 3 and the second electromagnetic wave irradiating means 4 of the present embodiment are composed of a glow bar light source which irradiates a global electromagnetic wave including far infrared rays to infrared rays (including a resonance wavelength of hydroxyapatite and collagen) and a collagen resonance light. A filter 3 that transmits only a wavelength (specifically, 6 ± 0.2 μm, approximately 6 μm, or 6.4 μm ± 0.4 μm, or both).
a, and a filter 4b that transmits only the resonance wavelength of hydroxyapatite (specifically, about 9.6 ± 0.5 μm or about 9.6 μm). The irradiation is performed by appropriately controlling the resonance wavelength of the collagen collagen and the resonance wavelength of hydroxyapatite by irradiation control means. Of course, the same effect may be obtained by using a laser.

The irradiation amount of the electromagnetic wave irradiation means may be provided so as to be feedback-controlled based on the intensity of the irradiated electromagnetic wave. For example, the radiation of the teeth 2 may be detected by a temperature sensor such as a HgCdTe sensor, and the irradiation amount of the electromagnetic wave irradiation means 1 may be controlled according to the detected value. Alternatively, the radiation of the teeth 2 may be received by an image receiving unit such as an HgCdTe image sensor, and the image may be displayed on a monitor device. Of course, a filter may be attached to improve accuracy.

The tooth modifying agent 1 contains a substance constituting a tooth. Specifically, in this embodiment, when a resonance electromagnetic wave is applied, an apatite crystal is formed or an apatite crystal grows. . More specifically, the tooth modifier 1 of the present embodiment has some fluidity so that the tooth modifier 1 can be easily applied to the surface of the tooth 2 thinly and uniformly, and Ca2 +, It contains PO43- in a supersaturated state and also contains hydroxyapatite crystal powder. Further, in order to prevent the teeth 2 from being excessively whitened by the coating of the tooth modifying agent 1, specifically, to obtain a color according to a user's tooth color or a user's preference,
A small amount of a coloring agent or a regulator for providing a transparent feeling may be included.
Here, Ca3 (PO4) 2 may be added together or together with Ca2 + or PO43- as a pretreatment.

In this embodiment, the tooth modifier 1 contains Ca 2+,
An example is shown in which PO43- and hydroxyapatite crystal powder are contained, but one or each of them is manufactured separately in a container such as a tube, and mixed together when used. Or may be sequentially applied to the surface of the tooth 2. In addition, tooth modification agent 1
Ca2 + and PO43- are used for the crystal growth of apatite (or the growth of crystals similar to the apatite) in a portion that comes into contact with apatite by electromagnetic wave energy when an electromagnetic wave is applied. It is integrated with the hydroxyapatite of the tooth 2 itself. The hydroxyapatite crystal powder contained in the tooth modifier 1 is partially integrated with Ca2 + and PO43-, and is integrated with the hydroxyapatite of the tooth 2 itself on the surface of the tooth 2. Where Ca2 +, P
O43- and the like may be added in the form of ions, or may be added in a form that releases ions. Also, C
When a3 (PO4) 2 is added, the crystal growth is further improved.

[Operation of First Embodiment] Next, an example of use of the tooth modification apparatus for teeth will be described. The tooth modifier 1 is thinly and uniformly applied to the surface of the tooth 2. Then, the first electromagnetic wave irradiating means 3 is operated to irradiate the electromagnetic wave radiated from the first electromagnetic wave irradiating means 3 to the surface of the tooth 2 to which the tooth modifying agent 1 has been applied. Here, first, 6 μm, which is the resonance wavelength of collagen of dentin, is irradiated. Here, since this resonance wavelength has a large individual difference, when the resonance wavelength of the affected part is measured and used,
Even better. Here, a pretreatment such as cleaning of the tooth surface or etching may be performed.

Then, the irradiation control means drives the second electromagnetic wave irradiation means 4 to obtain a tooth apatite resonance wavelength of 9.6.
Irradiate electromagnetic waves of μm. At this time, the first irradiation and the second irradiation are performed as shown in the time chart of FIG. 1B as an example. Then, first, the collagen of the dentin is excited, and the affinity between the modifier and the dentin collagen is promoted,
In addition, the reactivity between apatite as a modifier and dentin apatite increases. Then, while the apatite of the tooth modifying agent 1 crystallizes and grows, hydroxyapatite (or a crystal similar thereto) crystallizes also on the surface of the tooth 2 and a boundary between the tooth 2 and the tooth modifying agent 1. The portions are integrated, and as a result, the surface of the tooth 2 is coated with the tooth modifying agent 1.
It also facilitates the penetration of the modifier into the ivory tubules. Here, since this time chart is an example, any irradiation schedule may be used as long as an enamel-like coat can be applied to dentin and other dentin.

A plurality of the coating layers may be laminated. In this case, before forming the next coating layer, the surface of the layer coated on the teeth 2 may be appropriately subjected to a smoothing treatment. In addition, this operation may be performed after performing pretreatments such as various cleaners, cleaning, and etching.

[Effect of the first embodiment] As described above, a coating layer containing hydroxyapatite (or a crystal similar thereto) is formed on the surface of the tooth 2 by the tooth modifier 1, and the dentinal tubule is blocked. Since the surface of the dentin is enamelled, acid resistance is improved and caries can be prevented, and wear of the tooth 2 can be suppressed, due to good hypersensitivity prevention and strength improvement. In addition, tooth 2
The caries can be prevented by filling the cracks and the like that occur in the skin with hydroxyapatite (or similar crystals). This can exert an effect superior to existing hypersensitivity drugs. In this case, a coating layer may be laminated to cover the dentin.

[Structure of the Second Embodiment] FIGS. 2 and 3 are schematic diagrams of an electromagnetic interference device. In the first embodiment,
Although the example in which the surface of the tooth 2 provided with the tooth modifying agent 1 is directly irradiated with the electromagnetic wave of a predetermined wavelength irradiated from the first electromagnetic wave irradiation unit 3 has been described, in this embodiment, the first electromagnetic wave irradiation unit 3 is used. The electromagnetic waves radiated from the surface are caused to interfere by an interference device (FIG. 2, FIG. 3, etc.), and the electromagnetic waves resonated by the interference are radiated to the teeth 2 having the tooth modifier 1 applied to the surface. Of course, it may be applied to the second irradiation means 4.

This interference device uses a Mach-Zehnder type electromagnetic wave interference device shown in FIG. 2 or a Michelson type electromagnetic wave interference device shown in FIG.
In addition, the code | symbol M in a figure shows the mirror which reflects an electromagnetic wave,
Reference numeral HM indicates a half mirror that transmits part of an electromagnetic wave and reflects part of the electromagnetic wave. Then, the resonance wavelength is adjusted by adjusting the angle of the mirror M or the half mirror HM. In this embodiment, in order to obtain a resonance wavelength by the interference device, a laser light generator that irradiates a laser beam of a predetermined wavelength (for example, 633 nm) is used as the first electromagnetic wave irradiation unit 3.

The resonance wavelength of the interference device of this embodiment is
The resonance wavelength is set to 6 μm (or about 5.8 to 10 μm), which is the resonance wavelength of collagen constituting the organic component of the dentin of the tooth 2. Then, the surface of the tooth 2 is irradiated with the resonance electromagnetic wave generated by the interference device, and the interference wave which is the resonance electromagnetic wave is given to the tooth modifier 1 and the surface layer of the tooth 2. An incident angle adjusting means for changing the spread angle of the incident electromagnetic wave may be provided at the electromagnetic wave incident portion of the interference device. Further, an irradiation angle adjusting means for changing the spread angle of the irradiated electromagnetic wave may be provided in the electromagnetic wave irradiation portion of the interference device.

[Effect of the Second Embodiment] By irradiating the tooth 2 with the resonance electromagnetic wave using the interference device, the electromagnetic wave penetrates into the tooth modifier 1 and the surface layer of the tooth 2. For this reason,
The vibration of the collagen is increased, and the crystallization of hydroxyapatite (or similar crystals) at the boundary between the surface of the tooth 2 and the tooth modifying agent 1 is promoted, and the crystal growth is promoted. Can be formed on the surface of the tooth 2.

[Third Embodiment] FIG. 4 shows the operation of the third embodiment. The tooth modification apparatus for teeth includes an electromagnetic wave irradiation unit (3 or 4) for irradiating an electromagnetic wave, and a timing control unit for controlling the irradiation timing of the electromagnetic wave irradiated from the electromagnetic wave irradiation unit (3 or 4).

The electromagnetic wave irradiation means (3 or 4)
9.6 μm (or about 9.6 ± 0.5 μm), which is the resonance wavelength of hydroxyapatite constituting the enamel, and 6 μm, which is the resonance wavelength of collagen
It emits an electromagnetic wave (or 5.8 μm to 10.0 μm). For example, a glow bar light source and a filter may be used, or an infrared laser generator may be used. Further, an angle adjusting means for changing the spread angle of the radiated electromagnetic wave may be provided in the electromagnetic wave irradiating part of the electromagnetic wave irradiating means 1.

Here, the irradiation control means drives the first electromagnetic wave irradiation means 3 to irradiate the collagen with a continuous wave. On the other hand, the irradiation control means includes a second electromagnetic wave irradiation means 4.
Is divided into a first pulse and a second pulse to irradiate the tooth 2 to which the tooth modifying agent 1 has been applied. The irradiation interval between the first pulse and the second pulse is predetermined. Set to time. As means for irradiating the electromagnetic wave radiated from the electromagnetic wave irradiating means 1 in a pulsed manner, a shutter capable of shielding the electromagnetic wave may be used, and the electromagnetic wave may be turned on and off in a pulsed manner by opening and closing the shutter. The source of electromagnetic waves (global light source, laser generator, etc.) may be provided to be turned on / off or controlled by using a switch, or the voltage of the light source may be controlled.

First, the irradiation interval (predetermined time) between the first pulse and the second pulse by the irradiation control means is set to substantially zero.
, The interval is gradually widened, and as shown in FIG. 4, the interval t is set so that the intensity of the radiated electromagnetic wave B generated by the tooth 2 by the irradiation of the first pulse A1 and the second pulse A2 is maximized. It is a thing. The first pulse A1
And the process of irradiating the second pulse A2 at predetermined time intervals,
Irradiation control means may be provided so as to perform the measurement continuously plural times. Of course, the first pulse A1 and the second pulse A1
The process of irradiating 2 at a predetermined time interval may be variably provided in the case where the process is continuously performed a plurality of times. Further, the first electromagnetic wave irradiation means may perform pulse irradiation.

[Effects of Third Embodiment] As described above, a large radiated electromagnetic wave B is generated from the tooth 2 by irradiating the first pulse A1 and the second pulse A2 at predetermined time intervals. The crystal body generates phase matching vibration so as to generate the energy of the large radiated electromagnetic wave B, so that the tooth modifying agent 1 is crystallized and the boundary portion between the surface of the tooth 2 and the tooth modifying agent 1 is generated. In the above, hydroxyapatite (or a crystal similar thereto) crystallizes or grows, and the crystallized tooth modifier 1 and the human doxyapatite of the tooth 2 are integrated, resulting in a tooth modification on the tooth surface. Agent 1 is coated. At the same time, crystal modification is performed.

As described above, since the energy of the large radiated electromagnetic wave B can be obtained with a small energy, the first and second radiated electromagnetic waves B can be obtained.
The irradiation energy of the pulse can be suppressed, and as a result, the heat generation of the tooth 2 can be suppressed, and the burden on the surrounding tissue such as the pulp can be reduced.

[Modifications] In the above embodiment or modification, dentin is described as an example, but it may be applied to enamel, cement, bone and the like. To give an example,
The same effect as in the above embodiment may be obtained by adding mucopolysaccharide to enamel as one component of the modifier. Also, collagen is added beforehand as a modifier to dentin,
May be used. Further, chondroitin sulfate may be used. In this case, the electromagnetic wave may or may not be irradiated, and often has the same band as other additives.
The operator may determine which substance is to be subjected to the electromagnetic wave as described above.

The second embodiment and the third embodiment may be used in combination. That is, an electromagnetic wave irradiating means 1 for irradiating an electromagnetic wave, and an interference device 3 for causing the electromagnetic wave radiated from the electromagnetic wave irradiating means 1 to resonate in a surface portion of the tooth 2
And an irradiation control unit that controls the irradiation timing of the electromagnetic wave irradiated from the electromagnetic wave irradiation unit 1, and the irradiation timing of the electromagnetic wave pulse applied to the tooth 2 by the irradiation control unit may be a predetermined time interval.

The resonance electromagnetic wave may be of any type as long as it resonates with a resonance substance, such as a laser wave, a glow-bar light source wave, and an interference wave. As the resonance wavelength of the resonance substance, any wavelength of the resonance pattern such as a peak and a half width may be used.

In the above embodiment, two electromagnetic wave irradiating means are used. However, three or more electromagnetic wave irradiating means may be used, or a plurality of wavelengths may be taken out from one electromagnetic wave irradiating means and used.
A plurality of wavelengths may be obtained using a line width of a spectral line or the like. For example, a multi-wavelength laser or the like, or a global light source may be realized by using a plurality of filters. In the interference wavelength irradiation method, the interference angle may be changed continuously or intermittently to make the resonance wavelength multi-wavelength, or may be realized by using a plurality of interference units. In particular, the added apatite and the tooth apatite have similar resonance wavelengths, and therefore, a product utilizing a line width such as a spectral line or a multiple filter system is effective. As an example using the line width of the radiation light source, 1042 cm
The absorption wavelength of PO4 near -1 is different from the absorption wavelength of tooth apatite and added apatite.
O4) 2O, Ca5 (PO4) 3OH, Ca3 (PO
4) Any one of the above 2 or a combination thereof may be added to the tooth apatite, and both the tooth apatite and the additive may be used by irradiating electromagnetic waves to the tooth apatite. Any irradiation method and combination of additives may be selected according to the gist of the present invention, such as irradiation.

The resonance wavelength may be any wavelength as long as the tooth quality can be improved. As an example, 5.8 μm of collagen
10.0 μm (especially 5.8 μm to 6.2 μm, 6.0 μm
m-6.8 μm, 7.3-8.0 μm), 7.5 μm-10 μm for chondroitin, 7.6 μm-1 for PO

2.6 μm to 3.3 μm (especially 2.85 μm) 2.9 μm ± δ, 6.1 μm ± δ for H 2 O, 4.25 μm ± δ for CO 2, 2.7 μm to 2.8 μm for OH—
2.8 μm to 3.3 μm, 3.4 μm to 4.3 of NH
μm, 6.9 μm to 7.2 μm SOx 10 μm to 11 μm, 14 μm to 16 μm,
8.6 μm to 9.5 μm, 15 μm to 17 μm and the like are just examples. These may be used alone or in combination. In the case of a plurality, irradiation may be performed in a time-division manner, combined irradiation may be performed, or both may be performed. Further, an irradiation pattern such as pulse irradiation and continuous irradiation may be used in combination. Further, an electron excitation wavelength or the like may be used. In the above wavelength examples, ± δ is set as an example. However, this is the spread of the base, and may be applied to other resonance wavelengths.

The tooth modifier 1 may be mixed with a tooth reinforcing agent such as fluorine. By mixing fluorine, the hydroxyl group of hydroxyapatite is replaced with fluorine when irradiated with electromagnetic waves, and the tooth surface is strengthened. CaO, CaCO3, Ca3 (PO

Any of a8H2 (PO4) 6, apatite atom deficiency, apatite lattice deficiency, fluorapatite, or the like, or a combination thereof may be added. (It goes without saying that Ca3 (PO4) 2 may be an amorphous material or a crystalline material as long as the object of the present invention is achieved. But you can also
H2O may or may not be present in the molecule, for example, even if there is no H2O of CaHPO4.2H2O, it suffices to follow the gist of the present invention. Also, a pH adjuster may be added to the tooth modifier 1. As an example, it may be adjusted with HNO3 or the like for acidification, or may be adjusted with NH4 OH or the like for alkalinization.

A catalyst for accelerating crystallization may be added to the tooth modifier 1. Examples of catalysts include gold, silver, platinum,
Palladium, titanium, or the like may be used, or a catalyst using a means of charging or a polarization technique may be used in combination. When a catalyst is used as described above, tin ion, silane coupling, sol, or a surfactant may be used as a means for depositing the catalyst on the surface after irradiation with electromagnetic waves.

The viscosity of the tooth modifier is adjusted depending on the compounded substance such as low viscosity to high viscosity, the purpose of use, and the like. The substance to be added may be in a supersaturated state or may not be saturated (for example, low concentration).
Further, it may be used in powder form. As an example, a coating layer may be formed by growing crystals with a liquid tooth modifier and then sintering the compounded substance with a tooth modifier having a higher viscosity. Of course, a plurality of coating layers may be formed. An absorbing agent that absorbs the irradiated electromagnetic wave may be applied to the surrounding tissue to separate a portion where the coating is performed from a portion where the coating is not performed.

As an example of coating on the tooth 2, pits,
It may be used for preventive filling such as fissures. At this time, a tooth modifying agent such as apatite may be simply placed in pits, fissures, etc. and irradiated with electromagnetic waves, or the surface may be closed with a resin or cement after the tooth modifying agent is inserted. The irradiation of the electromagnetic wave may be performed a plurality of times. This preventive filling has higher safety than the conventional range sealant, and has remarkably excellent anti-caries properties and durability. Further, it may be used as a repair, capping, and lining for a cavity, an abutment or the like as appropriate. Also,
The apatite sintered body may be used as a core, and its periphery may be covered with a modifying agent and irradiated. In this way, crowns, inlays, veneers, etc. may be made and bonded to teeth. Further, an apatite coat may be applied to the inner surface of a crown, an inlay, or the like and the tooth may be combined with the apatite coat, or the apatite coat may be applied to the implant and the implant may be combined with the bone.

As an example of the means for irradiating teeth with an electromagnetic wave, an example using a laser light generator has been described above, but any other means for irradiating teeth with an electromagnetic wave capable of crystal matching may be used. Specifically, laser light, natural light, medium waves such as radio waves, X-rays, and sound waves, and any waves such as ultraviolet light, infrared light, and visible light may be used. Also, a coherent wave or an incoherent wave may be used. Here, the laser is NdYg, CO
2. Any oscillation mode such as He-Ne, Ar, and semiconductor laser may be used. Of course, a wavelength tunable laser using a grating, a double crystal, or the like may be used. Of course, the line width may or may not be used for various light sources. In addition, the waveform of the electromagnetic wave applied to the tooth includes a pulse wave, a continuous wave, a burst wave, a sine wave,
Any waveform such as a triangular wave, a sawtooth wave, a damped vibration wave, a sin / x wave, or an arbitrary waveform may be used as long as it matches the purpose.

The original wave as the interfered wave may be an electromagnetic wave of any wavelength other than light as long as a target wavelength is obtained,
Further, the irradiation wavelength and the amplitude may be appropriately changed depending on the properties of the living body or the like. For example, in teeth, if a wavelength of the order of 200 nm is used, diagnosis at the electronic level is possible, and skin,
Gum, various soft tissues, etc. have an absorber of about 6 μm and about 2.7 μm, and can be diagnosed at the molecular level. Under a specific magnetic field, diagnosis at the atomic level is possible. At this time, if the interference wave is a radio wave, an antenna, a waveguide, an electromagnetic field lens, or the like may be used. The infrared light may be received by an antenna. As the light source, any light source may be used as long as it is suitable for the present invention, such as a global light source, a lamp, and an LED.

Optical elements such as lenses and mirrors may be used to adjust the energy and range of the electromagnetic wave irradiation site.

In the above embodiment, the irradiation control means controls the electromagnetic wave irradiation means so that the irradiation electromagnetic wave can be subjected to amplitude modulation,
Irradiation may be performed with frequency modulation or phase modulation. Also,
The frequency (wavelength) may be continuously or intermittently varied by ± Δ. The arrangement of parts such as interference means is freely determined by the operator and is not particularly limited. An interference wave or an electromagnetic wave from an electromagnetic wave generation source may be guided by a waveguide element such as a fiber to irradiate an object such as a living body. At this time, the interference means may be at any position such as mixing and causing interference near the living body. Also, since the fiber in the visible light region is inexpensive, it is convenient if the wavelength before interference can be set in this band. The present device may be attached to a night guard, an occlusal floor, or the like, and used at bedtime. At this time, it is convenient to use a fiber or a battery.

The teeth may be irradiated with at least one or more pulsed electromagnetic waves at appropriate intervals, or may be continuous waves.
Further, the reflected or transmitted electromagnetic wave from the first pulse or the second pulse may be observed, or the phase matching may be adjusted by changing the interval between the first pulse and the second pulse. In addition, the re-radiation may be observed with one pulse,
Re-radiation in each pulse may be compared.

The wavelength of the electromagnetic wave applied to the tooth may be a single wavelength or a plurality of wavelengths. Further, the electromagnetic wave used for the interference may be a plurality of interferences in many directions, a multiplex interference in which a plurality of interference waves are overlapped, or a combination thereof. In this case, it is possible to irradiate a complex tissue with detailed irradiation for each part. The wavelength before the wavelength change may be used for excitation. The waves may be Fourier-combined.

When irradiating a tooth with an electromagnetic interference wave, any interference wavelength, interference method, and interference device may be used as long as interference can be given to the tooth. In this case, it is easy to control the polarization condition, frequency modulation, irradiation position, and the like. As a result, it is possible to further control the deep reach, and to irradiate from the front and back surfaces or from a considerably oblique position, so that the excitation wavelength can be widened and the reach to the excitation site can be increased.

In the above embodiment, the wavelength of the resonance wave generated by changing the interference angle is controlled. However, any one or all of the interfered waves (oscillation waves) can be individually or simultaneously subjected to frequency and wavelength control. May be changed to control the wavelength of the interference wave, or the interference wave may be controlled using a diffraction grating or a birefringent substance. The optimum excitation wave may be obtained from the reaction of the object, or may be obtained from the setting conditions of the device.

The light (excitation light) reflected by the phase conjugate mirror may be used by irradiating the teeth as electromagnetic waves. Conversely, the radiation light from the object may be reflected by the phase conjugate mirror to the light receiving unit, and the reflected light may be received. Further, heterodyne detection may be employed. In addition to these methods, wavelength conversion by a non-linear crystal may be added to the electromagnetic field generating means and used. In the case of these wavelength converters alone or in combination, the distortion of the electromagnetic wave due to the propagation medium in the propagation path of the electromagnetic wave due to the substance present in the region other than the site where the observation radiation is generated or the refraction material in the air is corrected, or the wavelength change or Transformation occurs favorably near the object (including the surface) and inside.
In the wavelength conversion of the above embodiment, the converted wave has a lower energy value because the wavelength is longer than the original wave.
In these conversion modes, the wavelength may be short, so that the energy value can be increased and used.

If the interference wave to be interfered is a wavelength that is more easily transmitted to the object, it is very effective for a digging lesion or a lesion with an undercut. In general, dental caries is often initiated immediately below the surface layer instead of the surface layer. In this case, it is suitable for annealing and diagnosis under such a surface layer. In addition, the polarization of linear, elliptical, and circularly polarized light may be controlled to enhance the deep reach. Linear polarization is advantageous when water-like substances such as from saliva or cutting equipment are present. Further, an optical path may be controlled by appropriately disposing a wave plate to control the polarization. Alternatively, a shutter or the like may be inserted in the optical path to control the irradiation pattern.

Excitation is easily understood as an increase in energy level, but negative excitation in the direction of lowering the energy of an object is also expressed here. For example, if various waves inside a substance are irradiated with waves that can interfere with them, the energy at a certain position inside the current substance may decrease. In addition, the function of a substance can also be controlled by irradiating various waves inside the substance with waves that can interfere with the various waves. In addition, efficient excitation can be achieved and a predetermined portion can be surely excited. Wavelength conversion means such as these may be employed.

It may be used for polymerization such as photopolymerization, thermal polymerization or chemical polymerization resin. In that case, a high polymerization rate is obtained, and even in a deep part, a polymerization better than surface irradiation is obtained. In general, since the photopolymerized resin in the oral cavity is polymerized at a wavelength that is easy for the eyes, it can be solved by setting the irradiation wave before wavelength conversion to a wavelength that is easy on the eyes by the present apparatus. In the above embodiment, the imaging element is HgCdTe, but CCD, InA2, Pb2nTe, Pb2, Cd2,
It may be used as another image sensor such as Cd2e, PzT, LiTaO3, thermopile, bolometer, and the like. A similar effect may be obtained by applying an antenna or the like. The observation wave may be a reflected wave or a transmitted wave.

The waveform detected by the receiving means is subjected to Fourier analysis,
Frequency analysis such as wavelet analysis and correlation analysis may be performed to further improve the accuracy for a specific wavelength. Also, a filter may be used on the receiving means, the subsequent electric circuit, or the analysis computer. In some cases, the receiving means may not be used, and the receiving means may be a wavelength selecting means. The display may be performed by any method such as black and white, color, non-gradation, gradation, or may be provided with a diagnosis and monitoring function such as display with a natural image. Also, it may be used by connecting to another diagnostic device.

In many cases, as the crystal matching progresses, the resonance wavelength shifts. In this case, it is more preferable that the irradiation wavelength be shifted by the irradiation control means in accordance with the shift of the resonance wavelength. Also, a pulse pair or group
Although it has been applied once, a pair or a group that irradiates three or more times may be used. An index or a threshold may be provided for the intensity, a threshold may be provided for a frequency such as a shift of a peak in a phosphate group, a threshold may be provided for Q of resonance, and any one may be selected. Good, or a combination. Further, the shape of the peak may be continuously monitored by the receiving means, and the Q value thereof may be set so as not to exceed a certain threshold value, and feedback may be performed to prevent crystal breakage. This setting includes a method of setting a destruction limit value and a method of feeding back to a maximum Q value.

In the crystal matching using a plurality of pulses, it is considered that the molecular vibration excited by the first pulse is phase-matched (or phase-inverted) by the second pulse, so that more coherency and efficient crystal matching can be achieved. It seems to be. At this time, the energy values of the first pulse and the second pulse are
The ratio may be set to be equal to one-to-many, or the reverse. For example, the first pulse is set to 1 and the second pulse is set to 2
And so on. Similarly, it is more preferable that the pulse width and the amplitude are set to values that can improve the tooth quality most. This is performed, for example, by performing the same operation as in the third embodiment so as to maximize the radiation wave from the teeth. This improves the crystal alignment of teeth and the like, which has not been possible before, ie, physical, chemical and biological properties such as anti-caries, anti-abrasive, anti-destructive, and acid resistance. Further, it may be possible to perform crystal matching by exciting an atom, an electron, a structure other than a molecule, or a crystal structure at a structure structure level. Further, a third pulse may be given when re-radiation occurs after phase matching. At this time, the efficiency is higher because the energy is close to saturation.

In the above embodiment, the resonance peak of the phosphoric acid group was used as an index of the resonance wavelength. However, which resonance peak or what kind of excitation peak was irradiated, or which wavelength such as the maximum or half value of the peak was irradiated. It is up to the operator to determine the irradiation standard, and there is no particular limitation. Further, the tooth is taken as an example, but other tissues or substances may be used. That is, any substance or object may be used as long as it has a crystal structure. Further, if matching equivalent to crystal matching can be obtained, it may be used for matching other structures. That is, the crystal structure is referred to herein as an object that causes these phenomena. The resonance wavelength at the irradiation site of the tooth, which is the irradiation target, may be examined, and the electromagnetic wave may be irradiated according to the wavelength. At this time, the degree of decalcification may be diagnosed based on the wavelength of the examination site, and the degree of the matching treatment may be diagnosed based on the wavelength to determine whether matching has been performed and the time required for matching. If possible, the invention may be applied not only to crystals but also to non-crystalline substances.

The wavelength conversion may be combined for all the elements, such as using several kinds of wavelength conversions shown in the above-described embodiment or the modified example, or may be performed individually for each element. . In addition, the style of the first irradiation means and the second
The combination of each means such as that of the irradiation means is also free. In addition, the term “interference” means that the interference angle is 0 degree or 1 degree.
It is needless to say that undulations and beats in the case of 80 degrees are included, and the irradiation angle may be any.

If the irradiation output in the above embodiment and modified examples is further increased, a cutting machine can be obtained. In this case, since cutting can be performed with less energy than a conventional cutting machine, the influence on surrounding tissues is small and the safety for the operator is increased. In this case, it may be used in combination with a destruction agent such as an acid to enhance the effect. Further, the denture reinforcement may be performed by repeating the micro-fracture and the matching or the recrystallization. Of course, an acid neutralizer may be used in combination.

The present invention may be used for efficient cutting and etching using an acid agent such as lactic acid, phosphoric acid, and maleic acid. In addition to atoms such as H ions, a molecule such as an acid releasing H ions may be used as an operator for cutting. Further, depending on the substance, cutting may be performed by adding an alkaline substance. In these cases, a low-concentration solution can be used, so that safety is high and efficient. Of course, tooth quality may be improved by repeating appropriate melting and growth of the coating. Further, the teeth may be etched before coating.

The above embodiments or modifications may be implemented individually or in combination. Also,
The effect may be further enhanced in combination with an appropriate drug.
Of course, each means may manually control its function or may be automated.

The tooth modifier may be used as a tooth modifier. Furthermore, the substances that make up the tooth mean all the units at the atomic level, molecular level, crystal, and tooth structure and structural level, and the tooth, such as the surface, inner surface, inducer, and ameloblasts, from embryonic life to death. Needless to say, it includes requirements for the configuration of the teeth in the dynamic state generated by the former, the tooth germ and the like.
