Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a new method and device for producing bleaching of natural teeth with pathological and normal staining.

BACKGROUND OF THE INVENTION For thousands of years, various bleaching products and techniques have been used to produce tooth bleaching, but due to unreliable results and difficult applications, they have never been popularized or commercialized. and no device for performing such treatment with good results and good clinical application has appeared on the market.

PROBLEM SOLVED BY THE INVENTION A method or device for bleaching teeth with normal staining has never been used and the present invention is first applied to normal teeth providing optimal results within a short period of time.

Changes in tooth staining are due to a number of etiologies or causes, including local, general, environmental and genetic, including certain antibiotics and deposition diseases.

The present invention is applied to distinguish between two types of patients.

One type is those whose tooth staining is considered normal and who seek to bleach their teeth to improve aesthetics.

-Two Another type of person is a person who has pathological coloring. In these cases, where there are serious therapeutic, social, and aesthetic issues and one relies on the dentist or stomatologist, who has neither the procedures nor the means to carry out bleaching, the only solution is generally porcelain. Covering the tooth with a cap that has an aesthetic front makes this procedure very expensive.

The process and device described are the result of research carried out by the applicant on his doctoral thesis on tooth bleaching at the School of Stomatology of the Faculty of Medicine of the University of Valencia (Spain). The initial process was patented in Spain by the applicant under Patent No. 528.007 dated June 3, 1985.

The applicant is the owner and manager of the Stomatological Research Center, who is also a Doctor of Medicine and a stomatologist, and whose doctoral thesis and Spanish Patent No. 528 were developed and researched there.
．． Major improvements to No. 007 followed.

A significant advantage of the method of the present invention over currently existing methods is the operating method and equipment used for the application of thermal and chemical bleaching products to the teeth and the soft tissue protector (gingival tissue) during treatment. and the use of various new substances such as oral mucosa). Other advantages include variable power and intensity ultrasound,
It is the use of ultraviolet and laser beams that facilitate the penetration of chemical bleaching products into the teeth, activate, catalyze, and provide energy for a greater bleaching effect, significantly reducing the duration of treatment and more Better results can be obtained besides easy clinical application.

For this reason, dental professionals, stomatologists, dentists, dentists5
．． Hospital personnel, nurses, assistants, etc. have the ability to solve a very wide range of problems and perform bleaching of teeth exhibiting pathological or normal staining due to any etiology, applied to any person upon request. Equipment and procedures are available to enable this.

Means for Solving the Problems With the above in mind, the invention provides that, using the method and device, optimum results are obtained in a short time by a process that is easily applied to those who wish to have whiter teeth. We propose a method and device for bleaching natural teeth with pathological and normal staining.

Therefore, the method of bleaching natural teeth with pathological and normal staining, which is the object of the present invention, involves applying various chemical products, such as degreasing enamel cleaners, to the tooth enamel and removing acidic engravings. It is characterized in that the moisture is extracted from solid tubules. The crown of the tooth to be treated is covered by a metal plate containing an absorbent material with a chemical bleaching product consisting essentially of 30-70% by weight hydrogen peroxide, alkali and salt, the product being in each case a mixture of reactive and surface-active components in defined proportions, and reactants determining the destruction of the molecular structure that reacts with the coloring component and absorbs a characteristic band of the visible spectrum that produces the tooth color; The chemical bleaching product then acts in the presence of heat that determines the reaction of the product acting on all sides of the tooth crown, and in order to produce tooth bleaching, the chemical bleaching product undergoes a reaction with the colored substrate. It is composed of a substance that allows greater and more rapid diffusion of the reactant through the physical structure of the tooth along with the catalytic reactant to achieve enamel-dentin bonding.

According to the invention, during the treatment, a separation product and a chemical and physical (metallic) protector are used, and after the treatment, the chemical bleaching product is isolated on the inside of the tooth and for 24 hours to 48 hours after the treatment. An enamel sealant is used that lasts for hours.

The temperature relationship in which the treatment is carried out is automatically adjusted and the calories that need to be produced at each moment are controlled such that the temperature is constant, preferably in the interval from 40 degrees Celsius to 55 degrees Celsius, said temperature being Periodically indicated by digital or visual instructions, the treatment time is automatically controlled and indicated by digital or visual instructions and selected and adjusted by external control.

To catalyze the reaction between tooth stains and chemical bleaching products,
UV light is applied. After each application of the chemical bleaching product, the light beams treated are low, medium and high power laser beams, which catalyze the reaction of the chemical bleaching product and accelerate the tooth bleaching effect.

In accordance with another aspect of the invention, a soft tissue protector is applied, polymerization and curing is effected by an activator, and a metal protector is applied to prevent diffusion of chemical bleaching products.

Finally, at the end of treatment, an enamel sealant is applied to close the tight tubules, isolating the chemical bleaching products incorporated into the tooth and facilitating internal degradation. Apparatus operative in accordance with the process objective of the invention, which likewise includes the latter objective, consists essentially of a bleaching apparatus, includes a heat generating apparatus, and has a heat generating element, temperature, time and alarm sensors and a controller implemented by a microprocessor. can be controlled by

According to an additional characteristic of the device object of the invention, a heating cube or a heat-containing plate, generally of aluminum or rust-free metal, is recognized, and indentations are provided in the heating cube sufficient for proper adaptation to each particular case.

A thermocube or heat-containing plate is made for each jaw individually or in standard form, and a reversible and mutual connection of two thermocubes or heat-containing plates is made simultaneously in both jaws or otherwise. The heat cube will be twice that of a single portion.

According to the invention, the heater of the thermal device is constituted by a low frequency power transistor that acts as a thermoelectric sensor to generate and measure the heat applied to the thermal cube or heat containing plate. The transistors or heaters constituting the heat generating device are placed in a capsule or annular surface which is placed on the heat cube or heat containing plate by some retention or friction mechanism.

Furthermore, according to another characteristic of the device purpose of the invention, for the heat generating device, a pulp meter for measuring the vitality of teeth, a color meter for the study and development of the color before and after treatment, a color meter for the study and development of the color of chemical bleaching products. A microprocessor fitted with a combination of UV emitters, ultrasound emitters and laser beam emitters as a catalytic agent and facilitating the entry of the same into the teeth is fitted with a program and a memory, and the details displayed on the monitor. A keyboard is also provided for transmitting information.

Ultrasonic emitters can be independent or integrated into the same heat generating device.

The metal protector consists of a thin prefabricated metal plate in the lower part that retains the remaining chemical bleaching products of the heat cube or heat-containing plate.

The chemical bleaching product used for the purpose of the process of the invention is a mixture of reactive components in defined proportions for each patient depending on the patient's characteristics and etiology and has the following properties as a whole: It is added, in contact with the ingredient to be colored,
By chemical reactions of oxidation and reduction, the treatment is carried out to destroy the molecular structure that absorbs characteristic bands of the visible spectrum that ultimately produce pathological or normal coloration r) reaction products in H and temperature conditions.

In this way, without eliminating the matrix in which pathological or normal staining occurs, it is corrected and rendered colorless, thus bleaching the tooth.

Along with the reactive products mentioned above, chemical bleaching products are also made up of substances that allow greater and more rapid diffusion of the reactants through the physical structure of the tooth, along with the reactants that catalyze the reaction with the coloring substrate, and the enamel. Achieve dentin bonding.

Chemical bleaching products can be mixed with anesthetics to desensitize or reduce tooth sensitivity during treatment and to make application painless.

Thermal cubes or metal heat-containing plates are preferably aluminum, stainless steel or other metals that are not easily oxidized by hydrogen peroxide, and are made of precise material to properly and uniformly transfer heat in dental prosthodontic laboratories. Design and sufficient thickness 2 are prepared for each individual as usual procedures such as polishing, grinding, polishing, etc. These heat cubes are located on the cheeks or vestibule,
Or even palatal or lingual, should cover the entire clinical return of the tooth being treated from the gingival margin to the incisor margin.

If the metal is other than aluminum or stainless steel, an outer coating of antioxidants should be provided as protection against chemical bleaching products.

Subsequently, in the area of contact with the teeth, an absorbent substance is applied, preferably by means of a thermally conductive adhesive, in contact with the teeth, which is saturated with bleaching agent during the treatment. This absorbent substance is
It should essentially be 100% cotton or other material that does not deteriorate in contact with hydrogen peroxide.

Another method of making heat-containing plates or heat cubes is industrially
That is, microlysis and injection of pre-fabricated molds, which are an extensive and diverse set for selection, fitting and preparation, depending on the needs of each patient, followed by examination of the correct fit in the upper or lower jaw. This set of standard heating cubes is used in 100% of cases.

To select a standard heat cube, start with plaster casts of the upper and lower jaws. Later, a plaster model is formed to the far side of the last tooth to be treated. canine to canine (6
Bleaching of the first premolar to first premolar (eight teeth) is recommended.

The incisor margin curvature of the model tooth is then transferred to the vestibular or buccal curvature of the thermocube, aligning the centerline with the thermocube centerline (
mesial side of the central incisors).

When the curvature of the incisor margin of the tooth is matched to the vestibular or buccal curvature of the selected thermal cube, this becomes correct for carrying out the treatment.

For this, two thermal cubes are selected for each individual, one with the upper teeth and the other with the lower teeth.

The joining parts of the heating cubes with each other are reversible, i.e. the same set of heating cubes acts on the upper and lower jaws indistinguishably, transferring the heat from the connection with the heater to the side heating cubes between each other, 2
The two heating cubes and heaters form a whole unified block.

To match the length of the standard heat cube, the center line of the plaster cast or tooth in the mouth is aligned with the center of the selected heat cube. A line is marked on both sides in a thermal cube coinciding with the distal side of the last tooth to be treated.

The heat cube is cut lengthwise along a line corresponding to the far side of the last tooth to be treated. In this way, the length of the standard thermal cube is determined.

To fit the standard heat cube height, the height is measured on the plaster model or on the tooth to be treated in the mouth. This height is transferred to a standard heat cube to the selected height in the lower incisor tooth of the same and then increased according to the thickness of the absorbent material placed.

The hot cube is cut to the selected height.

The tooth-to-tooth height adaptation is carried out by removing the height differences that exist between the teeth in the thermal cube.

For placement of the absorbent material with a small tongue pusher or similar device, in the area where the teeth of the thermocube are located, a very good layer of thermally conductive adhesive is applied, and then the absorbent material is pressed, adapted and glued there.

Once bonded, the remaining absorbent material is removed at the height and length of a standard hot cube.

If it is desired to carry out treatment in a single jaw, a neutral counter plate is placed, opposed to the heat cube, so that the heater of the thermal device is placed.

A standard thermal cube avoids individual manufacturing and obtains the same results at a much lower cost.

There are various types of thermal cubes or heat-containing plates that vary in design depending on their integration and adaptation to device systems for use as heating devices, ultrasound devices, laser and ultraviolet devices, etc.

With this type of standard heat cube, treatment is performed in both jaws simultaneously, significantly reducing treatment time.

A hot cube is then placed on the tooth to check for proper fit.
The test is performed in the patient's mouth.

The functions of the thermal cube are as follows.

1- Great wetting and absorption capacity of bleach by absorbent material.

2- Great compatibility of absorbent to heat cubes and teeth.

3- Adhesion of thermal non-isolating absorbents.

4- Uniform transfer of heat throughout.

5-Position close to the teeth of the temperature sensor that measures the actual temperature.

6 - Reversible connection of the thermal cube adapted to the heater of the thermal device so that the treatment is carried out in both jaws in a fairly short treatment time.

7- Low cost of manufacturing due to standard and mass production.

8- Transmission of ultrasound to bleaching agents and teeth.

9- No dirt or organic matter due to polishing.

Various heating devices and accessories used in the present invention are described below. One of these heating devices operates either by a transistor sensor acting time-shared as heater and temperature sensor, or by a heater resistor with an integrated and independent temperature sensor.

Heat is also supplied by a thermal liquid circuit with corresponding sensors.

As an important condition, all heat generating devices comply with international safety standards for electrical medical and dental equipment.

Another temperature-measuring exothermic device is based on the action carried out on the heat emitted by ultrasound, i.e. it facilitates the entry of chemical bleaching products and utilizes this to catalyze the reaction of the same, as much as possible. Instead, it has a sensor that accurately measures the treatment temperature.

The heating device provides a digital reading of the treatment temperature, and a 3 minute or 5 minute
It has a display for digital indication of treatment time with an alarm activated every minute.

Instead, help is provided to catalyze the reaction of chemical bleaching products by ultraviolet light and laser light. The exothermic device is electronically operated by a microprocessor with programs and memory and includes a pulp meter for measuring tooth vitality, a color meter for pre- and post-treatment color research and development, and a catalyst for chemical bleaching products. Ultraviolet emitters, ultrasound emitters and laser beam emitters can be used as agents and to facilitate their entry into the teeth.

Similarly, low, medium and high power laser beams
Applied independently to bleach teeth without chemical bleaching products, this laser radiation emits a specific wavelength that depends on the type and intensity of staining.

Instead, these devices allow microprocessor-based comparison studies to be performed before and after treatment, and to obtain reliable changes and measures in various treatment sessions. All of the data and information is on the monitor and conveyed by a keyboard that is easily read and understood.

Once the treatment time is selected, the treatment itself can be started, interrupted at any time and resumed when desired, and the actual treatment time calculated if desired.

EXAMPLES Example 1 Initially, we conduct a diagnostic study on a case, make a diagnosis based on the difference between the therapeutic coloration due to the etiology that produced it and the normal coloration by simple visual inspection or color meter, and determine the color tone and Consider strength.

Next, we conduct a study of the quality of the tooth enamel, whether it is normal or shows alterations such as degeneration, cracks, and fissures.

Since the selection criteria for the cases have been studied, we perform thorough daily dental cleanings, record the tooth color with a color meter and photographs, and have a guide to the number of sessions according to the tone and color intensity.

Afterwards, we obtain a model of some of the patient's teeth on one side and the lower jaw in plaster making several impressions taken with reversible or irreversible hydrocolloids.

These models serve to prepare and select several metal plates covering the tooth return on all four sides: mesial, distal, buccal or vestibular, palatal or lingual, and are herein referred to as , made individually for each individual, or selected from a standard set in various shapes and sizes, the most accurate for each individual or patient being called a thermocube or heat-containing plate.

These thermal cubes or heat-containing plates have a design and shape that allows them to be applied to a single jaw or both jaws simultaneously.

With these thermal cubes or heat-containing plates, the transfer of heat is carried out to the chemical bleaching product and to the teeth themselves for catalyzing the effect from temperature measurements or ultrasonic heating devices.

The patent is granted for ultrasonic cleaning and subsequent polishing of the teeth with bicarbonate and pressurized water, in which case the teeth are free of bacteria, plaque, and tooth enamel to facilitate subsequent preparation. be purified.

Subsequent application of stem anesthetic to the tooth being treated is optional. The patient rinses the mouth and the tooth is air dried. A lip separator is applied during the entire treatment session to clean the area or area being treated.

Subsequent acid engraving in enamel (e.g. 36%
This chemical product is applied in the tooth enamel, which together with orthophosphoric acid at -50%) produces cleaning and more thorough degreasing, which is very important to free entry into the enamel tubules where the bleaching agent penetrates. The degreaser and cleaner are applied for 5 to 10 minutes and the acid is applied for 2 minutes.

Until now these products have been applied to both jaws.

The jaws are then prepared and a highly volatile product is applied which extracts moisture and water from the enamel tubules with cotton wadding and tweezers, these are liquids that allow the bleach to penetrate undiluted and more quickly. will be removed. The tooth is then air dried. tS- Subsequently, the gingiva is air-dried and the chemical separation product is applied to the attached gingiva on the cheek or both the vestibule and palate from the gingival margin to the mobile gingiva (near the lower part of the vestibule). This product prevents direct contact of the soft tissue protector with the mucosa or gingiva, and once polymerized and the protector is removed, no tearing or abrasion of the gingiva or mucosa occurs. If the separator is not applied to the gingiva or mucous membrane, the patient will experience discomfort during the treatment and recovery period due to tearing or surface abrasion of the gingiva or mucosa when removing the protector.

The soft tissue protector is then applied to the separation product with a small metal or plastic spoon, small tongue pusher, ball device, or the like. The attached gingiva of the cheek or vestibule is
It is covered from top to bottom, ie from the lower part of the vestibule towards the gingival margin, covering the gingival ridges and curvatures and the interdental papillae. This soft tissue protector is a cyanoacrylate with certain precision so it is better applied.

The soft tissue protector is then activated with the activator and rapidly hardened in situ.

When the buccal or vestibular area is closed, it is applied to the palatal area as well.

A second coat of soft tissue protector is then applied over the first coat and activated. Application of the soft tissue protector should be double in two superimposed layers.

The area to which the soft tissue protector is applied should be slightly larger than that corresponding to the tooth to be treated.

This soft tissue protector is very important because without it the treatment would be very painful and some damage would be caused by the chemical bleaching products and produced in the gums or mucous membranes. By application of the soft tissue protector, total impermeability of the gums and mucous membranes is achieved with respect to bleaching agents, the latter causing no harm or discomfort to the patient. moreover,
This soft tissue protector is transparent, and if there are filtration pores through the protector due to transparency due to defects in clinical applications, a small initial white defect will be generated and further the protector will be placed over such filtration pores. This is a great advantage for applications.

To date, there is no effective form of protection for these oxidizing bleaches, the method, and the equipment underlying and accomplishing the present invention.

The lower jaw is then prepared and the same operation as the lower jaw is performed.

In this lower jaw, a metal protector was first fitted to the model and later of the first soft tissue protector.
placed in second place. The metal protector is prepared and properly deposited, then a second layer of protector is placed that slightly covers the metal protector, so that there is no filtration, and then activates the protector. Once the metal protector is in place, it is folded over on the back against the cheeks or vestibules or teeth, and the remaining bleach no longer flows behind and uses up the heat cube.

The bleaching agent placed on the tongue area of the metal protector must be absorbed by the suction of the dental device.

The metal protector (aluminum or other rust-free metal) prevents the spread of chemical bleaching products in the lower part of the mouth and the lower part of the vestibule, and also has a narrow front due to the design of the corresponding figure which fits very well. It is very important to be constructed from a metal plate made of. Its construction and manufacture are standard and come in various sizes to accommodate different sizes of patient's lower jaws.

Once the tooth enamel has been prepared and the soft tissues are protected in the entire area of both jaws being treated, this will instead prevent the sensitivity and possible irritation of the nerve ends of the teeth and allow the patient to be exposed during the treatment session. Prepared bleaches mixed with anesthetic agents are applied to eliminate or reduce discomfort.

The reactant or chemical bleaching product is mixed into the absorbent in the upper and lower heat cubes depositing various droplets until the absorbent is saturated and wet.

From this clinical stage onwards, the use of surgical gloves is recommended to avoid contact by dental professionals with bleaching agents.

Both thermal cubes are coupled to each other and to the heater and temperature sensor of the thermal device to be operated.

The heat cubes are placed correctly on the teeth and completely covered without putting too much pressure on them. The patient must protrude and close their mouth for a heat cube to be created in that location.

When the mouth is closed and pressure is applied, the remaining bleaching agent is placed on the lower jaw metal protector and can be absorbed by wadding or suction with the dental device.

Every 3 to 6 minutes some droplet of reactant or chemical bleaching product is applied to the hot cube. The thermal device indicates this time interval by an audible signal.

Treatment temperature ranges from approximately 40 degrees Celsius to 5 degrees Celsius depending on the coloring and patient.
Take a range of 5 degrees. The actual duration of each treatment session on two jaws is 1 hour at the same time, and after the application time on both jaws a minimum time of 30 minutes is considered sufficient, the beam tissue protector is removed with a small spoon or handle with a slight movement. The area is contained by a cylindrical container and is evaluated to be loose at the same time.

Example 2 In patients with FT classification M, upper and lower heat cubes cannot be applied at the same time, but one jaw treatment is performed in each session and the neutral plate is adapted to the heat cube for connection to the thermal device. . Treatment of one jaw per session is
It can be applied to all patients who desire it.

Once the treatment session is concluded, we record the new colors acquired and perform a comparative study to allow evaluation of the results.

Then, if interested, the tooth enamel is sealed, so that the bleaching agent introduced into the tooth continues to act and contact with the cheek area, saliva, food, etc. is prevented.

The result obtained by the method and device of the invention is bleaching in the entire clinical crown of the tooth being treated, i.e. all four sides of the tooth are freed from all of the colorant present in the dentin and tooth enamel. acts on

The bleaching achieved is uniform on all teeth treated, reducing the difficulties of application and resulting in a simple and effective treatment.

The treatments applied to the teeth are controlled in an accurate and reliable manner, providing us with great work security. Soft tissue is completely protected and subjected to contact with bleach. Similarly, the application of chemical bleaching products is facilitated on all of the teeth being treated, greatly improving the results.
