Description

Dental PRA operation method with improved adhesion {Method of operation PRA used for fixing orthodontics}

The present invention relates to a surgical method of dental PRA with improved adhesion, and more specifically, to induce a flow of adhesive, which is an adhesive resin, when bonded to a molar in the oral cavity and to firmly attach it, and to an arm surrounding the molar. This relates to a surgical method of dental PRA with improved adhesion, which allows the front part of the area to be extended to provide closer contact and the PRA with an expanded adhesive surface area to be firmly attached in the oral cavity.

In general, in dental treatment, the upper and lower molars are the teeth that are most often lost. When the opposing teeth are lost, the teeth become erupted, making dental treatment difficult. In particular, for the correction of molars, most of the time, a fixation source is fixed in the oral cavity and this fixation source is used. It is used to correct molars.

Orthodontics is a field of dentistry related to the management, guidance, and correction of abnormally positioned teeth to their appropriate positions.

Orthodontic treatment is useful in correcting defects in a patient's occlusion along with promoting hygiene and improving the overall aesthetics and health of the teeth.

Orthodontic treatment involves appliances known as brackets that are attached to the patient's incisors, canines, and premolars and molars.

After the brackets are placed on the teeth, an archwire is received within a slot in each bracket. Arch wires can serve as tracks to guide the movement of each tooth to the correct position for orthodontic treatment.

The end sections of the arch wire are typically contained within an appliance known as a buccal tube that is attached to the patient's molars. The brackets, archwires and buccal tubes are typically called braces.

Conventional braces are installed in the oral cavity, and food and plaque accumulate on the brackets and arch wires in the oral cavity. When food gets caught between teeth, there is a problem of causing cavities, gingivitis, and periodontal disease.

PRA (Palatal Retraction Arch,) is installed to be located in the lower part of the oral cavity, that is, in the inner part of the oral cavity, and is strongly adhered to the palate, holding it using strong force on both sides of the orthodontic support member 110, and then PRA (120) ) had the disadvantage of causing wounds in the oral cavity by having to remove the orthodontic support member 110, which weakened the fixing force of the orthodontic support member 110 or changed its position, making it difficult to attach it to the correct position, which was very uncomfortable for the recipient or patient, and the efficiency of orthodontic treatment was reduced. There was a problem.

Referring to FIGS. 1 to 7, the surgical method of dental PRA with improved adhesiveness of the present invention will be described. First, as shown in FIG. 1, the shape of the upper jaw (upper teeth) in the operator's mouth is scanned. The maxillary impression taking step (S10) to obtain the impression, the PRA (hereinafter referred to as 'PRA') production step (S12), the PRA preliminary step (S14), the PRA try-on step (S16), and the washing step ( S20), decalcification step (S22), drying step (S26), first surface treatment step (S28), adhesive application step (S30), first light polymerization step (S32), and adhesive application step (S34) ), excess resin removal step (S36), secondary light curing step (S38), and occlusion check step (S40).

In addition, a suitability confirmation step (S18) may be further included after the PRA try-on step (S16), and a deliming confirmation step (S24) may be further included after the deliming step (S22).

An upper jaw impression taking step (S10) in which an impression is obtained by scanning the shape of the upper jaw (upper teeth) in the operator's mouth, and after scanning the upper jaw of the operator, a plaster model is produced, and a PRA (PRA) is made to fit the upper jaw of the operator. Palatal Retraction Arch (hereinafter referred to as "PRA") is manufactured in an individually customized form according to the oral structure of each individual (S12), and the manufactured PRA is used for plaster modeling of the operator's oral cavity using a plaster model (PRA). Hereinafter referred to as 'PRA') is installed as a preliminary step (S14).

A try-on step (S16) is performed to testly install the PRA in the correct position by fitting it to the upper jaw in the oral cavity. In addition, it is confirmed and inspected whether the PRA is correctly installed in the practitioner's oral cavity (S18).

After performing the PRA try-on step and suitability confirmation as described above, the tooth surface is thoroughly cleaned (S20).

Then, the enamel formed on the practitioner's teeth is demineralized (S20), and it is checked and checked whether the enamel has been clearly demineralized (S24).

Next, after confirming that the enamel of the tooth has been demineralized, that is, after removing the enamel on the tooth surface, the tooth surface and the inside of the oral cavity are brushed off and dried using air (S26).

After drying the inside of the oral cavity, the surface area of the PRA in contact with the adhesive area of the molar is surface treated using a surface treatment agent (S28).

When surface treatment is performed on the contact area of the PRA, adhesive is applied to the adhesive portion (S30), and first light polymerization is performed on the applied adhesive using a light polymerization machine that outputs light of a specific frequency wavelength to polymerize and harden the adhesive (S32) ).

After the light curing, the adhesive is applied to the bonded area in contact with the tooth (S34), the PRA is accurately aligned with the tooth contact surface, the excess resin of the adhesive that flows out is removed (S36), and the excess resin that flows out is removed (S36). After removing the resin, it is secondarily light-polymerized using a light-curing machine to harden (S38).

After undergoing the first and second light curing as described above, the occlusion is checked again and the remaining condition of excess adhesive is checked and inspected (S40).

To be more specific,

In the maxillary impression taking step (S10), the mouth and jaw of the patient requiring occlusal surgery are scanned using 3D scanner equipment, and the entire mouth of the patient is scanned to obtain 3D oral shape data (digital scanning step).

That is, in the digital scanning step, the entire face is rotated 360 degrees using an around 3D scanner, and the oral structure of the patient is scanned three-dimensionally to collect three-dimensional image data of the oral cavity shape.

An oral model is formed with plaster using the oral shape data collected through the digital scanning step.

In the Palatal Retraction Arch (hereinafter referred to as "PRA") manufacturing step (S12), the PRA (100) is designed using the oral shape data collected by performing the digital scanning step.

At this time, the PRA design step may include a PRA design design step and a 3D design step.

The PRA design design step involves placing and connecting an arch-shaped or inverted cone-shaped PRA within the oral cavity while scanning the shape of the oral cavity.

At this time, the PRA is designed by considering the left and right tooth arrangement according to the shape, size, and arrangement of the patient's teeth.

The fixture 104 is formed according to the shape and size of the patient's teeth, and it is preferable to form at least two fixtures 104 and 105 symmetrically on the left and right sides according to the size of the PRA 100.

Then, a plurality of adhesive holes 26 are formed in the fixtures 104 and 105.

Then, when the design of the PRA 100 and the fixture 104 with a plurality of adhesive holes is completed, a 3D design step is performed using data obtained by scanning the shape of the oral cavity to implement it in 3D.

In the 3D design step, a model of the patient's teeth is formed and the shape of the oral cavity is formed as a model, the PRA (100) is placed in the plaster model formed by the oral cavity model, and the PRA (100) is connected and arranged.

In this way, after executing the PRA design step, the PRA 100 transmits the designed data file (STL) to a 3D printer to implement it into an actual shape, and after transmitting the processed data of the PRA 100, the The 3D printer that has received the PRA processing data performs the step of processing the PRA (100).

The PRA 100 is formed by expanding the width of the surface that adheres to the molar. In other words, it is preferable to form the bonding pad by extending it to the mesial side of the surface bonded to the molar (the surface between the second premolar and the first molar) to lower the dropout rate.

In the preliminary PRA step (S14), the PRA completed through the 3D design step and processing step as described above is seated and installed on the inner part of the plaster model of the oral cavity formed in the shape of the patient's mouth.

In the PRA fitting step (S16), after installing it on the plaster model of the oral cavity, the PRA (100) with the adhesive hole (26) formed in the oral cavity of the person being treated is properly seated and installed, and the seated PRA (100) is installed. Check the suitability of the designated position, shaking, coupling suitability, and sturdiness (suitability confirmation step (S18)).

In the cleaning step (S20), after the PRA fitting step as described above, the PRA is removed, and impurities attached to the tooth surface of the area where the PRA of the patient is to be bonded are thoroughly cleaned using an abrasive ointment.

Pumice is used as the polishing ointment, and the pumice is used for adhesion of orthodontic brackets, dental sulcus and composite resin restoration, and for cleaning the tooth surface or polishing amalgam or composite resin before bonding restorations. It can also be used to clean severely stained teeth.

In the decalcification step (S22), after the cleaning step (S20), the enamel is decalcified using an acid etchant on the cleanly cleaned tooth surface to remove residual substances attached to the tooth surface.

The purpose of demineralizing the enamel is to create an environment in which the resin, which acts as an adhesive, can be smoothly bonded to the tooth surface.

In addition, when confirming demineralization of the enamel of the attached tooth surface, it is desirable to observe the tooth surface until it appears as a white surface, and sufficiently perform the drying step described later (demineralization confirmation step (S24)).

In the drying step (S26), after removing the enamel on the tooth surface, since there are foreign substances, impurities, and residual substances in the oral cavity, air is sprayed to uniformly clean the tooth surface and between teeth and check whether the tooth surface has been properly decalcified. At the same time, a predetermined temperature is provided to the oral cavity to ensure sufficient drying.

In the first surface treatment step (S28), after decalcifying the enamel on the tooth surface as described above and drying the inside of the oral cavity and the tooth surface at a predetermined temperature, the fixtures 104 and 105 of the PRA 100 to be bonded to the teeth are used. After confirming whether the adhesive surface 18 formed is kept clean and visually checking the remaining level of impurities and the dry state, a surface treatment agent is applied. The surface treatment agent is applied using a microbrush. , the micro brush is applied to the adhesive surface 18 using a brush with a diameter of 0.3 - 0.9 micrometers.

At this time, in the adhesive application step (S30), the pretreatment agent is applied to the second micro brush and applied thinly and evenly to the adhesive surface 18 of the PRA 100, and at the same time, the same is applied to the area attached to the tooth surface. Apply the same pretreatment agent.

The pretreatment agent uses a bonding resin primer, and the reason for applying the pretreatment agent at this time is that the adhesive surface of the tooth surface and the PRA (100) are made of different materials, so adhesion is difficult, but the adhesive efficiency is greatly improved by using a bonding resin primer. It will be done.

The bonding resin primer includes a Bis-GMA resin monomer, a silane-treated silica filler, a photoinitiator (camphoroquinone (CQ)), and a trivalent amine as a reaction activator.

At this time, the particles of the silica filler are used within the range of 10 to 15 micrometers, and the content is 30-70%, the amine content is 0.2%, the photoinitiator CQ is 0.2 to 0.6%, and the resin monomer is 24%. It is desirable to use 29.2%.

After applying the bonding resin primer as a pretreatment to the PRA and the tooth surface as described above, the first light curing step (S32) is performed.

In the first photopolymerization step (S32), the bonding resin primer applied to the adhesive portion of the PRA and the surface treatment agent applied to the tooth surface self-polymerize, and a monomer (Monimer) with a double bond is free. The bonding resin primer is cured by addition polymerization using radicals.

As described above, in the first photopolymerization step, photopolymerization is used to form a solid resin matrix with a densely connected three-dimensional network structure.

In the adhesive application step (S34), after going through the first light polymerization step (S32), the adhesive resin is uniformly applied to the adhesive portion of the tooth surface. At this time, it is desirable to apply it so that it is positioned exactly on the tooth surface to be bonded and is not positioned higher than the occlusal surface of the teeth. This is because if the adhesive resin is positioned higher than the tooth surface, the PRA touches the opposing teeth before the patient chews, causing discomfort to the recipient and causing negative effects of orthodontic treatment.

The adhesive resin flows out from the top, bottom, left and right sides of the fixtures 104 and 105 of the PRA 100 of the present invention and is firmly attached to a large surface area inserted into the adhesive hole 26. Some of the adhesive resin is attached to the adhesive hole 26. flows out of the

In the excess resin removal step (S36), excess resin of the cured adhesive resin that flows out of the PRA 100 after the adhesive resin is applied is removed.

The second photopolymerization step (S38), which is performed after removing the excess adhesive resin, is a second photopolymerization step and is performed in the same manner as the first photopolymerization step.

After performing the second light curing step as described above, check the occlusion step (S40) to check whether the tooth surface and the PRA (100) are firmly attached and fixed in the correct position, and check whether any excess resin remains. .
