As shown in FIG. 1, a tooth to be bleached or improved in tooth quality is covered with a tooth modifying agent. The immediate polymerization resin is applied on the upper part as shown in FIG. Here, this resin may be photopolymerization or chemical polymerization. Also, in FIG. 1, the lip and tongue surfaces of the tooth are covered, but in the case of an instantly polymerized resin, only the lip surface may be covered without covering the tongue surface. It may be determined by the number. Then, it is kept for a certain period, and then removed. For example, it is held for about one day to one week. More specifically,
As a modifier, α-type Ca ₃ (PO ₄ ) ₂ made into a paste with distilled water or purified water is applied to the tooth surface, pits, fissures, cavities, etc. by means of a small brush or the like. Then, an immediate polymerization resin is put on it. At this time, it is more preferable to mix and use CaF ₂ , Ca ions, and PO ₄ ions.

Next, an example using a shape obtaining means for obtaining a tooth shape and a modifier holding means creating means for creating a modifier holding means based on the obtained shape will be disclosed. FIG.
First, an impression is obtained with a known impression material of a tooth or a dentition including the tooth for which it is desired to improve bleaching or dentin in the oral cavity.
This operation may be performed by MRI, CT or various three-dimensional measuring instruments. Then, gypsum is injected into the obtained impression to create a tooth model, or CAD is used to process shape data (tooth model) in a virtual space using a computer. A space for the modifier is secured by providing a spacer such as a wax at a portion of the model where the modifier is supplied. Then, a thermoplastic resin is pressed against the model. Alternatively, the holding means is processed using a CAM. Thereby, a modifier holding means is completed as shown in FIG. Here, also in this case, the coverage is determined by the range of the retained or modified teeth, and FIG. 1 is an example. Then, the modifying agent is filled in a space of the modifying agent holding means where the modifying agent is filled, and fitted into the oral cavity. This is convenient to use at bedtime.

This makes it easy to improve tooth quality at home. In addition, by using the (modifying agent) holding means, the function as a reaction improving material, that is, higher quality tooth quality can be improved.

Second Embodiment A second embodiment proposes use as a tooth modification device. FIG. 2b is a block diagram of the tooth modification device in the second 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. 2B is one in which tooth apatite has been deteriorated due to dental caries, abrasion, discoloration or acid. A modifier is applied to this portion and excited to be used to reinforce the surface layer or the inside of the surface. Of course, if the modifier or excitation penetrates deeply, it may be used to improve the deep part.

The tooth modification apparatus according to the second embodiment is characterized in that the excitation means of the second embodiment is characterized by imparting molecular vibration, and comprises an excitation means 3 for exciting molecules. In the example, basically only this excitation means 3 is used. The excitation means 3 of the present embodiment is adjusted to the resonance wavelength of Ca ₃ (PO ₄ ) ₂ (about 9 μm to about 10 μm) to the wavelength of Ca ₃ (PO ₄ ) ₂ present in the modifier. A) a molecular vibration plate 5 that produces molecular vibrations around
Power supply means (FIG. 3) for supplying power to the molecular diaphragm 5
Alternatively, in FIG. 4, only the electric wire portion 6 is illustrated. ). Here, any shape or material may be adopted according to the purpose of the present invention, such as a shape as shown in FIG. 3 or a shape as shown in FIG. As a specific example, this molecular vibration plate is made of alumina and silica stone, and can generate molecular vibration around 9.65 μm by power supply.
(Here, a nichrome wire is embedded in the molecular diaphragm and power is supplied thereto.) This is brought close to or in contact with the tooth coated with the modifier. As a result, excitation can be directly generated from the molecular vibration plate with respect to the resonance wavelength of Ca ₃ (PO ₄ ) ₂ . Here, Fe,
The excitation wavelength or wavelength range may be adjusted by adding Cu, Mn, Co, Sb, Sn, or the like.

Here, the molecular vibration may be transmitted directly from the molecular vibration plate, or a molecular vibration transmitting means may be used. As an example, silicone grease, H ₂ O, or the like is used as a molecular vibration transmitting means by inserting it into a molecular vibration plate and a substance to be excited such as a tooth or a modifying agent. Then, the resonance wavelength of Ca ₃ (PO ₄ ) ₂ is appropriately controlled by the excitation control means to excite the tooth 2 to which the tooth modifying agent 1 has been applied. Needless to say, a similar effect may be obtained here by using a CO ₂ laser or the like, or an excitation means such as a laser may be used to perform overtone excitation. 10 as an example
For example, a semiconductor laser having a harmonic wave of 0.96 μm to a reference wave of 9.6 μm, a 9th harmonic glass laser or a YAG laser, or an 8th harmonic approximation of a He—Ne laser of 1.15 μm,
For example, a bandpass filter is used for a glow-bar light source that can freely set the 8th harmonic and the nth harmonic by a dye laser. A similar effect may be obtained by using a molecular vibration generating means and a molecular vibration transmitting means as molecular vibration applying means as excitation means. As an example, silicone grease as a molecular vibration transmitting means is applied (applied) on the modifier, and a molecular vibration generating material (quick lime or the like) is applied (applied) on the molecular vibration generating material as a molecular vibration applying means. In addition, electromagnetic irradiation means such as a CO ₂ laser is used. At this time, the silicone grease absorbs the molecular vibration around 9.6 μm by the molecular vibration imparting means, and causes the molecular vibration around this wavelength. This allows this vibration to be transmitted directly to the modifier. (At this time, a shielding agent for shielding harmonics may be used, or harmonics may be transmitted as they are, or excitation may be performed, or only specific harmonics may be extracted and excited.) In this case, the molecular vibration transmitting means also acts as a reaction improver, that is, prevention of water evaporation of the modifier,
In this case, unnecessary gas such as CO ₂ is prevented from being mixed, the reaction is promoted, and the crystallinity of apatite is improved.
Here, these may be held by a tooth covering such as a shell, a jacket crown, a template, and a night guard covering the teeth, or may be used as a reaction improving agent. In this case, a first space for the modifying agent to cover the teeth and a second space for the agent for excitation may be provided, or the first space and other excitation means (such as electromagnetic wave irradiation means) may be used. Is also good.

Here, the molecular diaphragm is formed into an array or the like.
The energy amount in the excitation range may be controlled. In this case teeth
Gives optimal molecular vibration to the fangs
Can do things. Also, the molecular vibration wavelength of each element is different
May be used. In this case, the peak wave in crystal growth

It may be driven at the optimum wavelength by using the receiving means in combination.

Further, H₂3μ which is the absorption wavelength of O

The reaction may be promoted. Specifically, H₂O resonance wavelength
(Specifically, 2.9 μm ± δ, 6.1 μm ± δ, or

And so on. More specifically, molecular oscillating a nichrome wire
For example, it is used for a moving plate. Of course Erbium Yag
A similar effect may be obtained by using a laser or the like. Ma
They may be used simultaneously or in a time-division manner. Also the reference vibration
In addition, overtones may be used. As an example, C

And so on. Of course, if it works, use other harmonics.
May be used. Especially when using overtones, set the reaction cell
Into the resonator, or measure the re-radiated wave and excite it.

In addition, the excitation of a plurality of wavelengths, that is,
You may have. As an example, the above Ca_Three (PO₄)₂Waves

For example, wavelength is used. Example of using multiple excitation means
Is given by H as shown in the chart of FIG.₂O excitation intensity
Curve (top) and Ca_Three(PO₄)₂Excitation curve (bottom)
This is shown as an example.

Further, a third wavelength may be added.
As an example, 2.7 μm of OH group of apatite etc.
To 2.8 μm or 15.7 μm. And even in the case of excitation of these multiple wavelengths,
Overtones may be used. As an example, the first excitation means includes:
9.65 μm, the second excitation means is 4.825 μm, or the first excitation is performed at 2.4 μm.
The ratio, arrangement, and the like of the overtone and the reference vibration may be in any combination, or only the overtone may be used alone.

Incidentally, feedback control may be provided based on the intensity of electromagnetic waves radiated from the excited teeth. For example, the radiation of the teeth 2 may be detected by a temperature sensor such as a HgCdTe sensor, and the excitation amount of the excitation means 1 may be controlled according to the detected value. Further, the radiation of the tooth 2 is HgCd.
An image may be received by an image receiving means such as a Te image sensor, and the image may be displayed on a monitor device. Of course, a filter may be added to improve the accuracy. Here, the wavelength may be variably given by the excitation means to select the wavelength that is most absorbed, or the tooth surface may be excited evenly.

The tooth modifying agent 1 contains a substance constituting a tooth. Specifically, in this embodiment, when a resonance molecular wave is applied, apatite or apatite-like crystal is formed, or apatite or apatite-like crystal is formed. A crystal grows. More specifically, the tooth modifier 1 of this embodiment, those having a slight flowability as easily donate thin and uniform manner tooth modifier 1 to the surface of the tooth 2, Ca ₃ in an aqueous solution (PO ₄ ) ₂ and hydroxyapatite crystal powder (0-99.9 in molar ratio)
99%), and here contains apatite and Ca ₃ (PO ₄ ) ₂ in a ratio of 10: 1.
(Of course, the weight ratio or the volume ratio may be used.) Further, Ca ions or PO ₄ ions may be added. Here, the ratio of these substances, the thickness to be applied, or the applied amount and time amount of H ₂ O to be supplied may be controlled to control properties such as the completed thickness of the coating layer and the color tone. (H ₂ O used was degassed or decarboxylated, but may not be degassed or decarboxylated. In addition, H ₂ O adjusts the oxidation-reduction potential to increase the reaction rate and the crystallinity. May be controlled,
It may be used as a pretreatment agent or used in combination. )

Further, a small amount of the tooth 2 is used so that the tooth 2 does not become too white by the coating of the tooth modifying agent 1, specifically, a color according to a user's tooth color or a user's preference. A coloring agent or an adjuster that gives a sense of transparency may be included. Here, Ca ²⁺ , PO ₄ ^3−, or Ca ₃ (PO ₄ ) ₂ may be added to the teeth in advance, or the pretreatment may be performed with an acid, alkali, or neutral water. . Here, Ca ²⁺ and PO ₄ ^3- may be added in the form of ions, or may be added in a form that releases ions.

In this example, the tooth modifying agent 1 contained Ca ₃
An example in which (PO ₄ ) ₂ and hydroxyapatite crystal powder are contained is shown, but one or each is manufactured independently in a container such as a tube, and used by mixing at the time of use. Or may be sequentially applied to the surface of the tooth 2, and Ca ₃ (PO

Ca ₃ (PO ₄ ) ₂ becomes an apatite precursor and is converted into apatite, which first becomes apatite itself. Further, in this process, the apatite added together is bonded to each other, so that it also acts as an apatite binder. Furthermore, since Ca ₃ (PO ₄ ) _{2 at the} stage before reaching apatite is in the state of easy-bonding apatite, the binding property of the modifier is further increased. Here, Ca ₃ (PO ₄ ) ₂ was used as an apatite precursor, an apatite binder and an easily bondable apatite.

The apatite may be treated with an acid, an alkali, or sintering, and used as an apatite precursor, an easily bondable apatite or an apatite binder. The treatment for these modifiers may be applied to the tooth surface.

[Operation of Second Embodiment] Next, an example of use of a 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 excitation unit 3 is operated to apply the molecular vibrations applied from the excitation unit 3 to the surface of the tooth 2 to which the tooth modifying agent 1 has been applied. Here, first, 9.65 μm, which is the resonance wavelength of Ca ₃ (PO ₄ ) ₂ , is applied. Here, α type is used, but β type or amorphous type may be used as long as the same effect is obtained. Here, the resonance wavelength changes depending on the state of Ca ₃ (PO ₄ ) _{2 in} the modifier, or when converted to apatite, and the like, so it is more preferable to measure and use the resonance wavelength of the modifier. . Here, a pretreatment such as cleaning of the tooth surface or etching with an acid, alkali treatment, or laser annealing may be performed. In addition, these teeth may be treated with the modifier.

When a plurality of excitations are performed, one
As an example, the excitation control means drives the double excitation means 4,₂

, So enamel-like coating is possible
Thus, any excitation schedule may be used.

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. Further, the above-described excitation means may obtain the same effect by using an electromagnetic wave irradiation means.

[Effects of the Second Embodiment] As described above, since the coating layer containing hydroxyapatite (or similar crystals) is formed on the surface of the tooth 2 by the tooth modifier 1, the acid resistance is improved. Thus, dental caries can be prevented, and wear of the teeth 2 can be suppressed. Further, cracks and the like generated in the teeth 2 can be filled with hydroxyapatite (or similar crystals) to prevent dental caries. As a result, an effect superior to that of the existing bleach or restoration material can be exhibited. In this case, a coating layer may be laminated to cover the dentin.

[Structure of Third Embodiment] FIGS. 6 and 7 are schematic diagrams of an electromagnetic interference device. In the above second embodiment,
Although the example in which the molecular vibration of the predetermined wavelength given by the excitation means 3 is directly applied to the surface of the tooth 2 to which the tooth modifying agent 1 is applied has been described, in this embodiment, the first electromagnetic wave is used as the excitation means. The electromagnetic waves emitted from the irradiating means 3 are caused to interfere with each other by an interference device (FIGS. 6 and 7), and the electromagnetic waves resonated by the interference are applied to the teeth 2 provided with the tooth modifier 1 on the surface. . Of course, you may apply to the 2nd irradiation means 4 as a double excitation means.

This interference device uses the Mach-Zehnder type electromagnetic wave interference device shown in FIG. 6 or the 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. Here too, overtone excitation may be performed, or if the overtone of the original wavelength is, for example, 633 nm, which is the wavelength of the present embodiment, it may be used. Specifically, it is excited at 633 nm as the fifth harmonic of PO ₄ . In this case, when irradiating only this, the interference unit may not be used, or the interference unit may be used to use the interference wave. A plurality of overtones may be excited by using or using an interference unit. When used in combination, they may be used as double excitation means. Further, at this time, any laser may be used, for example, a laser to be used or a wavelength of the laser may be selected according to an excitation substance.

[Effects of Third Embodiment] By irradiating the teeth 2 with the resonance electromagnetic waves using the interference device, the electromagnetic waves penetrate into the tooth modifier 1 and the surface layer of the teeth 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.

[Fourth Embodiment] FIG. 8 shows the operation of the fourth embodiment. The tooth modification apparatus for teeth employs the excitation means of the second embodiment as the excitation means. And timing control means for controlling the application timing of molecular vibration applied from the excitation means (either one or both of them may be used). here,
Electromagnetic wave irradiating means for irradiating electromagnetic waves (either one or both of three or four may be used) and this electromagnetic wave irradiating means (one or both of three or four may be used) The same effect may be obtained by providing a timing control unit for controlling the irradiation timing of the electromagnetic wave irradiated from the above.

The excitation emitting means (3 or 4) is provided with a molecular vibration of 9.6 μm (or about 9.6 ± 0.5 μm) which is the resonance wavelength of hydroxyapatite constituting the enamel of the tooth 2 and H ₂ O. And one or both of molecular vibrations near 3 μm (or 2.9 μm ± δ, 6.1 μm ± δ), which is the resonance wavelength of
The present embodiment uses the same excitation means as the embodiment.

When an electromagnetic wave is used as the excitation means, 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 applied electromagnetic wave may be provided in the electromagnetic wave irradiation part of the electromagnetic wave irradiation means 3 as the excitation means.

Here, the excitation control means drives the excitation means 3. The excitation control means divides the molecular vibration applied from the excitation means 3 into a first pulse and a second pulse, and applies the first and second pulses to the tooth 2 to which the tooth modifying agent 1 has been applied.
The application interval between the first pulse and the second pulse is set to a predetermined time. The means for applying the pulsed molecular vibration from the excitation means 3 uses a circuit for controlling the power in a pulsed manner, and this circuit turns the molecular vibration ON-OFF or weakly in a pulsed manner. When electromagnetic waves are used here, the electromagnetic wave sources (shutters, pulse lasers, Q switches, etc.) are used to turn on and off electromagnetic wave sources (global light sources, laser generators, etc.).
It may be provided so as to control the FF or the intensity, or the light source voltage may be controlled. If H ₂ O is excited, a continuous wave is applied in this embodiment, but a pulse may be used. Here too, overtone excitation may be performed.

First, the interval (predetermined time) between the application of the first pulse and the second pulse by the excitation control means is set to substantially zero.
, The interval is gradually widened, and as shown in FIG. 8, the application of the first pulse A1 and the second pulse A2 generates the tooth 2 and / or the modifying agent or the modifying agent. The interval t is set so that the intensity of the radiated electromagnetic wave B is maximized. Note that the first pulse A
The process of applying the first and second pulses A2 at predetermined time intervals is as follows:
Excitation control means may be provided so as to perform a plurality of times continuously. Of course, the first pulse A1 and the second pulse A2
May be variably provided in the case of performing the step of exciting at a predetermined time interval a plurality of times continuously. Further, the excitation means may be pulse-excited.

[Effects of the Fourth Embodiment] As described above, a large radiated electromagnetic wave B is generated from the tooth 2 by applying the first pulse A1 and the second pulse A2 at predetermined time intervals. By generating phase-matching vibration, the crystal is crystallized to generate the energy of the large radiated electromagnetic wave B, so that the tooth modifier 1 is crystallized and the boundary between the surface of the tooth 2 and the tooth modifier 1 is formed. In the above, hydroxyapatite (or a crystal similar thereto) crystallizes or grows, and the crystallized tooth modifier 1 and 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. Here, this excitation may be applied only to the teeth to improve the crystal.

As described above, since the energy of the large radiated electromagnetic wave B can be obtained with small energy, the first and second radiated electromagnetic waves B can be obtained.
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.

[Modification] In the above embodiment or modification, enamel and dentin are described as examples, but they may be applied to 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,
It may be used, or it may be applied in a two-stage configuration in which collagen or collagen gel is applied first and then the modifier main body is applied, or in a three- or more-stage configuration. In addition, various substances contained in the pulp may be used as a modifier as a pulp capping agent directly in the modifier, or a modifier as an enamel coating or a dentin coating may be applied to the pulp. It may be used as a direct pulp capping agent or an indirect pulp capping agent. In those cases, an antimicrobial agent may be used. Further, the present invention may be applied to bone loss or fracture due to periodontitis or trauma. 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.

In the above embodiment, the excitation means is mainly a molecular vibration imparting means for directly applying vibration or an electromagnetic wave irradiating means for exciting a substance through an electromagnetic wave, and a heating means or a mechanical vibration imparting means is used as an exciting means. Is also good. As an example, hot air may be applied, a heater may be applied directly or indirectly, reaction heat of a chemical reaction, or blowing with a flame if possible.

In the second embodiment, the same effect may be obtained by using a laser or the like. Here, the laser light or the like is appropriately focused or diffused by a lens or a mirror for irradiation. The energy amount in the range may be controlled. Further, the filter may be changed, or a continuously variable filter such as a diffraction grating may be used. In this case, it is possible to respond to the peak wavelength shift in crystal growth, to respond to the variation of the resonance wavelength of apatite on the tooth surface, or to irradiate alternately, continuously, or stepwise the various resonance wavelengths of teeth and additives. As a result, the crystal growth can be improved.

Further, 3 μm, which is the absorption wavelength of H ₂ O, is used.
The reaction of Ca ₃ (PO ₄ ) ₂ may be promoted by irradiating only an electromagnetic wave near m. Specifically, a filter 4a that transmits only the resonance wavelength of H ₂ O (specifically, about 2.9 μm ± δ, 6.1 μm ± δ, or about 3 μm) is employed. Of course, the same effect may be obtained by using an erbium yag laser. In addition, heating may be performed simultaneously or independently by conducting heat without interrupting the heat of the light source or the like.

Further, irradiation with a plurality of wavelengths, that is, a second electromagnetic wave irradiation means 4 and a filter 4b may be provided. As an example, a filter 4b that transmits only the resonance wavelength of H ₂ O (specifically, 2.9 μm ± δ, 6.1 μm ± δ, or about 3 μm) in addition to the wavelength of Ca ₃ (PO ₄ ) ₂ is employed. Do. As another example, it may be applied to dentin collagen. Specifically, the resonance wavelength of collagen is 6 ± 0.
About 2 μm or 6 μm, or 6.4 μm ± 0.4
For example, a resonance wavelength of one or both of μm and μm is used.

Further, a third wavelength may be added.
As an example, 2.7 μm of OH group of apatite etc.
2.8 μm.

The third embodiment and the fourth 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. Of course, the molecule providing means may be used in combination or may be replaced.

When an electromagnetic wave is used as the excitation means, it may be coherent or incoherent. (Coherent may have a stronger matching effect.) Resonant electromagnetic waves can be generated by resonating with a resonant substance such as a laser wave, a glower light source wave, an interference wave, a medium wave, a quantum wave, a particle wave, or an electron beam. Something like that is fine. Furthermore, sunlight or the like may be guided by a fiber or a mirror for excitation. At this time, a filter or the like may be used to select an appropriate wavelength, or a polarizing element may be inserted to provide polarized light.

As the resonance wavelength of the resonance substance, any wavelength or wavelength band in the resonance pattern, such as a peak or a half width, may be used.

In the above embodiment, one or two excitations

Reference vibration excitation or overtone excitation may be performed using 1 or vn (n> 0) as the reference vibration. (The same applies to other substances.) As an example, the reference vibration excitation or the overtone excitation may be performed by using various lasers or a light source using a filter such as a lamp such as tungsten as an n-th harmonic such as a resonance wavelength. In a specific example, 633 nm of a He—Ne laser is used as the five-fold oscillation of ν1 in PO ₄ . Of course, fine adjustment may be performed with a tunable semiconductor laser or the like. In the case of a plurality of excitations, time-division excitation may be used, excitation may be used together, or both may be used. Further, an excitation pattern such as pulse excitation and continuous excitation may be used in combination. Furthermore, an electron excitation wavelength or the like may be used.

[0091] 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, the 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, or the like and excited, or the surface may be closed with a resin or cement after the tooth-modifying agent is inserted. The excitation may be performed a plurality of times. This preventive filling is higher in safety than the conventional range sealant, and is much more excellent in anti-caries properties and durability. In addition, repair, pulp capping, etc.
It may be used as lining. Alternatively, the apatite sintered body may be used as a core, and its periphery may be covered with a modifier to excite the core. 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 apatite coat may be combined with the bone. Furthermore, it is possible to excite the teeth by exciting them, and then remove the surplus part,
The upper part of the coating layer may be excited with resin, metal, glucan, or porcelain for a long time.

[0093] As an example of the means for irradiating the teeth with the electromagnetic wave, an example using a laser light generator has been described, but other means may be used as long as it is an excitation means capable of matching or growing crystals. Specifically, laser light, natural light, medium waves such as radio waves, microwaves, X-rays, and sound waves, and any waves such as ultraviolet light, infrared light, and visible light may be used. In addition, a coherent wave may or may not be a coherent wave as long as it is an excitation unit that can perform crystal matching or crystal growth. Here, the laser is NdYg, C
Any oscillation mode such as O ₂ , He—Ne, Ar, a dye laser, and a 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. Further, the waveform to be excited on the tooth may be any waveform such as a pulse wave, a continuous wave, a burst wave, a sine wave, a triangular wave, a sawtooth wave, a damped oscillation wave, a sin / x wave, an arbitrary waveform, etc., 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 excitation wavelength and the amplitude may be appropriately changed depending on the properties of the living body or the like. For example, in the case of teeth, if a wavelength of the order of 200 nm is used, excitation at the electronic level is possible, and it can also be used for diagnosis. And excitation or diagnosis at the molecular level is possible. Excitation or diagnosis at the atomic level is possible under a specific magnetic field. 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. The light source is a global light source, lamp, L
Any light source, such as an ED, suitable for the present invention may be used. As an example, in the case of ultraviolet rays, an ultraviolet lamp, Kr
A Cl laser, a KrF laser, or the like may be used.

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

In the above embodiment, the excitation control means may control the excitation means so as to apply amplitude modulation, frequency modulation, and phase modulation to the irradiation electromagnetic wave for irradiation. Further, 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 electromagnetic wave from an interference wave or 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, a shell, a crown, a mouthpiece, or the like, and used at bedtime or the like. At this time, a fiber as a waveguide may be attached to them to excite them in order to transmit electromagnetic waves to them, or a heater may be attached to them as an example of excitation means, and they may be driven by a battery or the like. A current may be passed from the power supply to the tooth surface to excite the modifying agent or the tooth. In that case, a microwave may be used to create a local circuit locally to allow the current to flow, or the heat may be used to excite the electrode, and of course, an electrode may be placed on the tooth. In this case, it is convenient to attach an electrode to the modifier holding means. As another example of the excitation means, a chemically reacting substance such as a known body warmer may be held on them to excite it, or as another example of the excitation means, MutansStreptococci may be used.
The bacteria such as i may be attached for excitation (in this case, a low sugar concentration is used as the basis, and a high sugar concentration is used instead of etching). Excitation may be performed by using molecular vibration, heat or hot water, or a gargle containing heat or molecular vibration for excitation, or an electromagnetic wave generating means may be used. 2SO ₂ + O ₂
^← _→ An exothermic reaction such as 2SO ₃ may be used. Further, at this time, the tooth improving agent may be degassed and attached to a night guard or an occlusal floor. Many of these are suitable for home bleaching. The excitation means may be used in combination.

At least one or more pulsed electromagnetic waves may be applied to the teeth 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 at 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. This makes it possible to further control the reach of the deep portion, 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 increases.

In the above-described embodiment, the wavelength of the resonance wave generated by changing the interference angle is controlled. 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 conversion means alone or in combination, the distortion of the propagation path of the electromagnetic wave due to the propagation medium in the electromagnetic wave due to a substance present in a portion other than the generation site of the observation radiation wave or a refraction substance in the air is corrected, or a change in wavelength or Transformation occurs favorably near the object (including the surface) and inside.
Also, 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 interfered wave to be interfered has a wavelength that is more easily transmitted to an object, it is very effective for a digging lesion or a lesion having an undercut. In general, dental caries is often initiated not directly on the surface but directly below the surface, so that it is suitable for annealing and diagnosis under such a surface. In addition, the polarization of linearly, elliptically or circularly polarized light may be controlled to enhance the reach in the deep part. Linearly polarized light is advantageous when water-like substances such as from saliva or cutting equipment are present. Further, an optical path may be controlled by appropriately arranging 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.

The term "excitation" is used to indicate that the energy level is increased, but also negative excitation in the direction of decreasing the energy of the object. 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. Also, as an adjustment of excitation, H ₂
When the excitation is performed while supplying O appropriately, the excitation of H ₂ O may be increased when the amount of water is large, and may be reduced when the amount of water is small.

It may be used for polymerization of photopolymerization, thermal polymerization, or chemically polymerized 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 easily harmful to the eyes, this problem 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, InA ₂ , Pb ₂ nTe, Pb ₂ , Cd ₂ ,
It may be used as another image sensor such as Cd ₂ e, PzT, LiTaO ₃ , 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, it is not necessary to use the receiving means, and the wavelength selecting means may be used as the receiving means. The display may be performed by any method such as black and white, color, non-gradation, gradation, and may be provided with a diagnosis and monitoring function such as a display combined with a natural image. Further, 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 excitation control means shifts the excitation wavelength in accordance with the shift of the resonance wavelength. Also, a pulse pair or group
Although it has been applied twice, pairs or groups that excite three or more times may be used.

An index or a threshold may be provided for the intensity.
A threshold may be provided for the frequency such as the shift of the peak in the phosphate group, a threshold may be provided for the resonance Q, and any one of them may be selected or a combination thereof. 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. Also, a wavelength shifting agent for tuning the peak to the excitation wavelength may be used. H as an example
Changing the amount of 2O changes the resonance wavelength centered on the peak. As described above, the wavelength shifting agent is a kind of a reaction improving agent that is very effective when a fixed laser is excited. Of course, natural light or other excitation means may be used.

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 fourth 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 texture structure, or a crystal structure at a texture structure level other than a molecule. Further, a third pulse may be given when re-radiation occurs after phase matching. At this time, since the energy is close to the saturation, the efficiency is further improved.

In the above embodiment, the resonance peak of a phosphate group or the like is used as an index of the resonance wavelength. It is up to the operator to determine which wavelength, such as the maximum value, half value or 1 / n value (n> 0) in the peak, as the reference for excitation, is not particularly limited. In addition, teeth are taken as an example, but other tissues,
It can be a substance. That is, any substance or object may be used as long as it has at least 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.

It is also possible to examine the resonance wavelength at the excitation site of the tooth to be excited, and to excite the electromagnetic wave in accordance with 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. 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 embodiment or the modified example, or may be performed for each element alone. . Also, the combination of each means such as the type of the excitation means and that of the double excitation means is also free. In addition, it goes without saying that the term "interference" includes undulations and beats when the interference angle is 0 degree or 180 degrees, and the irradiation angle may be any.

If the excitation output in the above embodiments and modifications 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, a molecular vibration transmitting agent may be used. For example, in the case of 2.9 μm, H ₂ is placed between the tooth and the molecular vibration applying means.
O is used.

Further, the denture may be strengthened by repeating the micro-destruction and the matching or 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 that releases 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.

Here, any one of resin, resin precursor, ceramics, and ceramic precursor, or any combination thereof may be included. In this case, it is possible to improve the aging of the teeth and tooth modification agents by covering the coating agent, etc., and to bond to known restoration materials such as metals, resins, or ceramic restoration materials that exist in the oral cavity for a long time. it can. As an example, a well-known composite resin is provided on a modifier, and a part of the modifier is provided with a fiber or the like that transmits electromagnetic waves of a resonance wavelength (some wavelengths may not be necessary) to prevent evaporation of water. Crystal growth can be achieved by preventing CO ₂ from being mixed. Also, if the neighboring teeth are filled with resin, a mixture of resin and modifier may be applied to the surface and connected, or the surface may be whitened by applying to a known discolored resin filler. Is also good. This may be performed using a known porcelain or the like, or porcelain powder may be used as a filler of a modifier.

The above embodiments or modifications, or individual components of each means or modifier, may be practiced individually or in combination. Further, the effect may be further enhanced by combining with an appropriate drug. Further, the modifying agent may use a supply means such as a night guard, a bite guard, a mouthpiece, a shell, a sprayer, or the like, or may use an excitation means attached to these supply means. Of course, each means may manually control its function or may be automated. The treatment to the modifier may be applied to the teeth or vice versa. Further, each component of the modifier may be separately applied, for example, ultrasonic spraying may be used, or it may be manually added.

The tooth modifying agent may be used as a tooth modifying material, and other agents may also be used as materials. 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. Needless to say, this includes the configuration requirements of the teeth in the dynamic state generated by the former, the tooth germ and the like. As an example, all phosphates go to apatite, and apatite goes to almost all phosphates, and so on. Furthermore, it goes without saying that the above chemical substances and the like also include non-stoichiometric compounds. Excitation is easily taken only in the positive direction, but it goes without saying that it has both positive and negative vectors, and it goes without saying that promotion of diffusion of ions into the tooth is also a kind of excitation.
