Abstract

This dental prosthetic block is an abutment-integrated prosthetic block for cutting processing, which is an integrated crown block and abutment made of a material that does not require heat treatment after cutting processing. The integration is achieved using an adhesive layer containing a hardened polymerizable organic compound, which allows cutting processing such as CAD / CAM processing while the crown and abutment are integrated, and allows artificial teeth such as temporary or permanent teeth to be made by cutting in the block state. Furthermore, since no further heat treatment is required after cutting processing, it is possible to shorten the treatment time for implant restoration and enable one-day prosthetic treatment.

Description

[Technical field]

[0001] The present invention relates to an abutment-integrated prosthetic block for cutting processing, and provides a dental prosthetic block in which a crown block made of a material that does not require heat treatment after cutting processing and an abutment are integrated, and which can be applied to cutting processing such as CAD / CAM processing in an integrated state. [Background technology]

[0002] At present, the major issues in dentistry include improving the aesthetic appearance of patients and reducing the time required for one-day treatment. For this reason, dentistry has been leading the development of related materials and equipment, with zirconia, crystallized glass, and composites being widely used in the material area, and CAD (Computer Aided Design) / CAM (Computer Aided Manufacturing) equipment being widely used in the equipment area. Due to these changes, dentistry has been making improvements in the aesthetic aspects requested by patients and reducing the time required for dental treatment with one-day prosthetics. However, in response to the ongoing demands of patients and the needs of dentists, there is a continuing need for further methods in addition to those currently in use.

[0003] Generally, prostheses are divided into inlays, onlays, veneers, crowns, etc. according to the part to which the material is applied, and into temporary teeth and permanent teeth according to the purpose of use. The required physical properties differ depending on each part and purpose of use, and materials can be selected according to the physical properties. For example, composites and polymethyl methacrylate (PMMA) have excellent workability and aesthetics, and have the advantage of being able to be implanted in the mouth immediately without further heat treatment after processing, but they have lower physical properties compared to other materials and are mainly used for inlays and onlays, which serve as temporary teeth. Currently, research and development of composites with high physical properties is being continuously conducted, and as a result, they can be applied to permanent teeth such as crowns of premolars. Zirconia is known to have the highest physical properties among dental prosthetic materials except metal, but has problems such as low aesthetics and the need for further heat treatment after processing, and is mainly used for permanent teeth such as crowns of molars. However, in order to solve these problems, zirconia materials that have lower physical properties than existing zirconia materials but have improved aesthetics by changing the content of Y2O3 (yttria) are being developed and commercialized. Currently, one of the problems with zirconia and crystallized glass materials is the problem of extending treatment time due to additional heat treatment after processing, and solving this problem is becoming another issue, and advanced companies are starting to release products that solve this problem one by one.

[0004] Dental implants are a method of fixing metal to the gum bone and restoring the part above the gums with a crown made of dental prosthetic material, and their use in dental treatment is steadily increasing. Implants are roughly composed of three parts: the crown, the abutment, and the fixed body, and each part is connected by cementation and fixed screws. The crowns used in implants are applied to prevent problems in functional and aesthetic areas before connecting the temporary tooth to the permanent tooth that is finally created after implant placement. One of the problems with restorations using implants is the long treatment time.

[0005] The applicant has been working hard to create a crystallized glass block connected to a superstructure, and has already filed and received registration for this (Korean Patent Registration No. 10-1796196). In this patent, the applicant disclosed a method of bonding a high-strength zirconia post that can act as a core inside the crystallized glass block, and a method of bonding a metal link that is fastened to an implant fixture to the zirconia post, when fabricating artificial teeth using a CAD / CAM processing method using a crystallized glass block, which is the material for artificial teeth. Specifically, this patent required a step of bonding the zirconia post by heat treating it at 700℃~900℃ for 1~2 hours using an inorganic bonding agent. [Prior art documents] [Patent documents]

[0021] The abutment-integrated prosthetic block for cutting of the present invention can be subjected to harsh machining such as cutting using CAD / CAM and other methods while the abutment and crown are in an integrated block state, which makes it possible to produce artificial teeth such as temporary or permanent teeth that are suited to individual patients, and does not require further heat treatment after cutting. The implant procedure can be completed by implanting the crown with the integrated abutment after cutting, which shortens the treatment time for implant restoration and makes it possible to perform one-day prosthetic procedure. [Brief description of the drawings]

[0022] [Figure 1] FIG. 2 is a schematic diagram of an abutment-integrated prosthetic block for cutting processing. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The present invention will now be described in more detail with reference to the drawings.

[0024] The above and further aspects of the present invention will become more apparent from the following preferred embodiments, which are described with reference to the accompanying drawings, in which: FIG. 1 is a block diagram of a method for manufacturing a semiconductor device according to the present invention;

[0025] Generally, the structure of a surgical implant is divided into a fixture, an abutment, and a crown. The fixture is embedded in the alveolar bone, and over time, bone adhesion occurs, acting as an abutment. The abutment is a part that is connected to the fixture, and acts as a connection between the fixture and the crown that acts as a tooth, and is usually connected to the crown by a cementation method. This procedure is usually performed in stages over a long period of time.

[0026] FIG. 1 is a schematic diagram of an abutment-integrated prosthetic block for cutting processing according to the present invention. This is a dental prosthetic block for cutting processing in which a crown block 1 made of a material that does not require heat treatment after cutting processing and an abutment 2 are integrated together, and the integration is achieved by an adhesive layer 4 containing a hardened product of a polymerizable organic compound.

[0027] Such a prosthetic block includes a screw access hole 3 in consideration of final connection with a fixture, and of course includes a mandrel 5 in consideration of cutting processing.

[0028] In order to integrate the abutment 2 made of various materials with the crown block 1 made of a material that does not require heat treatment after cutting, and to perform cutting processes such as CAD / CAM processing and laser milling in this state, the integration method and materials can play an important role.

[0029] From this viewpoint, the adhesive layer preferably contains a cured product of a polymerizable organic compound. That is, it is preferable to integrate the abutment 2 and the crown block 1 by using the curing reaction of the polymerizable organic compound. In particular, at this time, depending on the composition of the cured material, adhesion that overcomes the material difference between the abutment 2 and the crown block 1 can be achieved. Specifically, the cured material preferably contains at least one inorganic filler selected from barium silicate (BaO3Si) and silicon dioxide (SiO2) dispersed in an organic matrix made of a cured product of (a) two or more compounds selected from bis-GMA (2,2-bis[4-(2-hydroxy-3-methacryloyloxy propoxy)phenyl]propane), triethylene glycol dimethacrylate (TEGDMA), and diurethane dimethacrylate (UDMA), and (b) two or more compounds selected from HEMA (2-hydroxy ethyl methacrylate), PMDM (bis[2-[(2-methyl-1-oxoallyl)oxy]ethyl]dihydrogen benzene-1,2,4,5-tetracarboxylate), and 10-MDP (10-methacryloyloxydecyl dihydrogen phosphate).

[0030] Here, the (a) compound is an organic compound that allows the compound to exhibit a viscosity that enables application to each material, and is preferably a mixture of low-viscosity and high-viscosity compounds, specifically, a mixture of triethylene glycol dimethacrylate (TEGDMA) and at least one selected from bis-GMA (2,2-bis[4-(2-hydroxy-3-methacryloyloxy propoxy)phenyl]propane) and urethane dimethacrylate (UDMA).

[0031] The compound (b) can act as an adhesive compound that improves the adhesive strength of each material.

[0032] In order to improve the physical properties of the adhesive layer, it is preferable that the adhesive layer contains at least one of barium silicate (BaO3Si) and silicon dioxide (SiO2) as an inorganic filler, since this can improve the adhesive strength between the organic and inorganic materials.

[0033] In this case, the content of the organic matrix and inorganic filler in the adhesive layer 4, and the mixing ratio between the (a) compound and the (b) compound constituting the organic matrix can of course be appropriately adjusted in consideration of the material of the crown block and the material of the abutment.

[0034] In such an adhesive layer, the cured product may be a product cured by photocuring or thermal curing.

[0035] In the prosthetic block with an integrated abutment for cutting according to the present invention, the crown block 1 is preferably made of a material that does not require heat treatment after cutting, because if the material is one that exhibits the required physical properties only after a further heat treatment is performed in a state where a predetermined shape is completed by cutting in the block state, a further heat treatment process may cause a problem that the size of the material may change in some cases. From this perspective, in the prosthetic block of the present invention, the crown block preferably contains at least one material selected from polymethyl methacrylate polymer (PMMA), a composite of ceramics and resin, zirconia, and crystallized glass, and in particular, in the case of crystallized glass, it is preferable that the crystallized glass contains lithium disilicate crystals as the main crystal and can be cut.

[0036] Here, PMMA polymer has lower physical properties than other materials and is generally applicable to temporary tooth blocks, but temporary teeth are implanted in the oral cavity after implantation before using permanent tooth prostheses, and are used to check whether the fixation of the anchor and the periodontal part is done well after implantation, whether the patient has pain during chewing, or for aesthetic functions before making permanent tooth prostheses. In the case of a composite of ceramics and resin, zirconia, or crystallized glass, etc., they are materials that show higher physical properties than PMMA polymer, and can form a crown block 1 that can be applied to permanent tooth prostheses.

[0037] More specifically, the ceramic-resin composite may be prepared using hydroxyethyl methacrylate (HEMA), 2,2-bis[4-(2-hydroxy-3-methacryloyloxy propoxy)phenyl]propane (bis-GMA), triethylene glycol dimethacrylate (TEGDMA), diurethane dimethacrylate (UDMA), urethane dimethacrylate (UDM), biphenyl dimethacrylate (BPDM), n-tolylglycine-glycidylmethacrylate (NTGE), polyethylene glycol dimethacrylate (PEG-DMA), and oligocarbonate dimethacrylic acid ester. The ceramic composite may be a hardened material of at least two polymerizable organic compounds selected from the group consisting of polymerizable organic compounds such as cellulose acetate, cellulose esters, and at least one inorganic material selected from the group consisting of barium silicate-based crystallized glass, leucite-based crystallized glass, alumina, zirconia, and glassy materials, and such a composite of ceramics and resin is a material that can be applied to anterior teeth and premolars. It is needless to say that the contents described in Korean Patent Publication No. 10-2017-0173152 by the present applicant can be referred to in detail for this.

[0038] In the case of zirconia as the material for the crown block 1, it may be preferable for it to contain 2 to 10 mol % of yttria. Since this can be applied immediately after cutting without further heat treatment, it can be applied to the molar area, where high physical properties are generally required.

[0039] On the other hand, in the abutment-integrated prosthetic block for cutting processing of the present invention, the material of the abutment 2 is not limited, and it can include, for example, at least one material selected from titanium or an alloy thereof, and zirconia.

[0040] When an abutment 2 of such a material and a crown block 1 are integrated with an adhesive layer 4 containing a cured product of a polymerizable organic compound, in order to improve the interlayer adhesion, it is preferable that the surface of the crown or the surface of the abutment adjacent to the adhesive layer 4 is surface treated using acid etching or sand blasting.

[0041] A method for producing such an abutment-integrated prosthetic block for cutting includes the steps of: preparing a crown block made of a material that does not require heat treatment after cutting (S1); preparing an abutment (S2); drilling a hole in the crown block according to the shape of a predetermined abutment (S3); applying an adhesive composition containing a polymerizable organic compound to the abutment (S4); fastening the abutment with the adhesive composition applied to it to the drilled crown block (S5); and hardening the crown block with the abutment fastened thereto to integrate the abutment and the crown block (S6).

[0042] In this case, the adhesive composition containing the polymerizable organic compound preferably contains (a) two or more compounds selected from bis-GMA (2,2-bis[4-(2-hydroxy-3-methacryloyloxy propoxy)phenyl]propane), triethylene glycol dimethacrylate (TEGDMA), and diurethane dimethacrylate (UDMA), (b) two or more compounds selected from HEMA (2-hydroxy ethyl methacrylate), PMDM (bis[2-[(2-methyl-1-oxoallyl)oxy]ethyl]dihydrogen benzene-1,2,4,5-tetracarboxylate), and 10-MDP (10-methacryloyloxydecyl dihydrogen phosphate), (c) at least one inorganic filler selected from barium silicate (BaO3Si) and silicon dioxide (SiO2), and (d) a photoinitiator or a thermal initiator.

[0043] Here, the compounds (a), (b) and (c) are the same as those described above.

[0044] (d) In the case of a photoinitiator, it is preferable that the compound or polymerization initiator system is one in which curing is initiated at a wavelength of 350 to 450 nm. For example, a photoinitiator such as camphorquinone (CQ) can be used. At least one photoinitiator selected from 1-phenyl-1,2-propanedione (PPD), diphenyliodonium hexafluorophosphate (DPIHP), and p-octyloxy-phenyl-phenyl iodonium hexafluoroantimonate (OPPI) can be included. As a catalyst, the photoinitiator system may be a photopolymerization initiator system containing a tertiary amine such as the aromatic ethyl-4-dimethylaminobenzoate (EDMAB) which is relatively hydrophobic, or the hydrophilic aliphatic 2-(dimethylamino)ethyl methacrylate (DMAEMA).

[0045] Meanwhile, the thermal initiator is preferably one that can perform thermal curing at 80 to 150° C., and may include a peroxide-based initiator such as benzoyl peroxide (BPO).

[0046] In the step (S1) of preparing a crown block made of a material that does not require heat treatment after cutting, the material related to the crown block 1 is the same as that described above. At this time, it goes without saying that the crown block may have the mandrel 5 attached thereto.

[0047] Moreover, the materials and the like related to the abutment 2 in the abutment preparation step (S2) are the same as those described above.

[0048] In the step (S3) of drilling the prepared crown block according to the shape of a predetermined abutment, the drilling is performed according to a structure so that the abutment can be fixed to the crown block 1 prepared including a normal mandrel 5. Here, the expression "according to the shape of a predetermined abutment" can be understood as a structure including a screw access hole 3 for connecting to a fixture, taking into consideration the final implantation of the prosthesis.

[0049] As described above, the surface of the crown block adjacent to the adhesive layer 4 and the surface of the abutment are preferably surface-treated layers. From this perspective, it is preferable to subject the surface of the crown block drilled in step S3 to surface treatment using acid etching or sandblasting, and then fasten it to the abutment 2 to which the adhesive composition has been applied.

[0050] Meanwhile, in the step (S4) of applying the adhesive composition containing a polymerizable organic compound to the abutment, in the same vein, it may be preferable to surface treat the surface of the abutment using acid etching or sandblasting, and then apply the adhesive composition containing a polymerizable organic compound to the surface.

[0051] In this case, the surface treatment may be preferably performed in both steps S3 and S4, or may be performed in only one of these steps.

[0052] The abutment coated with the adhesive composition is fastened to the drilled crown block (S5), and then the crown block to which the abutment is fastened is hardened to integrate the abutment and the crown block (S6).

[0053] In this way, the abutment and the crown block are integrated through a simultaneous hardening reaction, so that the interlayer bonding strength can be efficiently improved.

[0054] At this time, step S6 is preferably performed by photocuring with a wavelength of 350 nm to 450 nm or by thermal curing at 80 to 150°C.

[0055] According to the above-mentioned manufacturing method, the crown block 1 made of various materials and the abutment 2 made of various materials are integrated through the hardening reaction of a specific polymerizable organic compound, which allows the integration through a relatively gentle process without harsh heat treatment, thereby eliminating the risk of changes in the physical properties of the crown block material.

[0056] In addition, the abutment-integrated prosthetic block for cutting obtained by the above-mentioned method can be directly processed by CAD / CAM processing or laser milling to create an abutment-integrated artificial tooth according to the patient's needs. If it is directly connected to a fixture, it can shorten the treatment time for implant restoration and enable one-day implant treatment.

[0057] In particular, even if cutting processes such as CAD / CAM processing or laser milling are performed while the prosthetic block is in an integrated state with the abutment, the excellent adhesive strength and shear bond strength ensure mechanical stability, and because the abutment and crown are integrated, the possibility of secondary infection due to bacterial penetration depending on the individual treatment can be reduced.

[0058] Thus, the artificial teeth obtained by cutting the abutment-integrated prosthetic block can be either temporary or permanent, depending on the material of the crown block.

[0059] While the present invention has been described above with reference to one embodiment shown in the drawings, this is merely an example, and those skilled in the art will appreciate that various modifications and equivalent alternative embodiments are possible. [Industrial Applicability]

[0060] The present invention relates to an abutment-integrated prosthetic block for cutting processing, and provides a dental prosthetic block in which a crown block made of a material that does not require heat treatment after cutting processing and an abutment are integrated, and which can be applied to cutting processing such as CAD / CAM processing in an integrated state.

[0061] The abutment-integrated prosthetic block for cutting of the present invention can be subjected to harsh machining such as cutting using CAD / CAM while the abutment and crown are in an integrated block state, which makes it possible to produce artificial teeth such as temporary or permanent teeth that are suited to individual patients, and also allows the implant procedure to be completed by implanting the crown with the integrated abutment after cutting, without the need for further heat treatment after cutting, thereby shortening the treatment time for implant restoration and making it possible to perform one-day prosthetic procedure.
