Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a denture base resin material mainly used for producing dentures and lining (renovating) denture bases.

[0002]

2. Description of the Related Art In general, a denture is prepared by taking an impression of a patient's mouth and preparing a gypsum model, forming a denture base on the gypsum model using wax, and arranging artificial teeth thereon. The denture prepared as described above is buried in the flask using an investment material, wax is flown with hot water or the like to form a cavity in the denture base portion in the investment material, and then the liquid and powder of the denture base resin material are mixed. And the required amount is mixed and kneaded with a spatula, etc., left to stand for a certain period of time, and the polymerization proceeds to fill the cavity in the investment material in the flask in a rice cake state. After being polymerized and hardened by heating in a microwave oven or the like, it is manufactured by cooling, excavating from the investment material, and performing shape modification and polishing.

[0003] In addition, the lining (renovation) of the denture base is usually performed by placing an impression material using a denture base of a denture in which the mucosal surface side is further removed as a tray, obtaining a functional impression, and directly burying the investment material. And then buried in the flask, and then the impression material is removed to form a cavity in the investment material. Thereafter, the denture is placed in the cavity in the investment material in the flask in the same procedure as in the preparation of the denture base. The required amount of liquid and powder of the floor resin material are measured, mixed and kneaded with a spatula etc. into a rice cake-like shape, filled into the cavity in the investment material in the flask, cooled, excavated after polymerization and curing. In addition, a method called an indirect method of performing shape correction and polishing has been performed. However, since it takes time for lining by this method, a direct method using a resin material for a denture base of an immediate polymerization type or a photopolymerization type has been considerably performed. In this method, after the mucosal surface side of the denture is further removed, a necessary amount of liquid and powder of the denture base resin material and powder are weighed, mixed and kneaded to form a rice cake-like shape, and directly placed on the mucosal surface side of the denture. , Inserted into the oral cavity to give the form by repeating the trial in the patient's oral cavity several times, and then left outside the oral cavity to polymerize or irradiate with light to polymerize the denture lining How to do it.

Conventionally, denture base resin materials used for the production and lining (upgrading) of such dentures include a liquid mainly composed of methyl methacrylate and a liquid mainly composed of polymethyl methacrylate. It is composed of a powder to which a polymerization catalyst has been added.When used, the required amount of the liquid and the powder are measured, uniformly mixed and kneaded using a spatula, etc., and left for a certain time to form a rice cake. It is necessary to use it. However, the time it takes to form a rice cake depends on the environmental temperature, and the monomer remains highly volatile even after the rice cake. Not only is it difficult to start the side arrangement, but also the odor and irritation may cause discomfort to the operator and the patient, and in some cases may hurt the operator's health.

[0005] In addition, such conventional denture base resin materials have a small elastic energy value, which is a characteristic of acrylic materials, and are hard and brittle, so that they absorb the force and impact applied to the denture base. However, there is a drawback that when a shock is applied due to dropping or the like, it is easily damaged. Further, when dentures are dug out of the investment material during the production of dentures, thin portions such as the periphery of the denture base and portions having a shape in which stress tends to concentrate are often damaged. In addition, it is essential that the conventional denture base resin material be used by mixing a liquid and a powder, but there is a disadvantage that air bubbles are entrained in the mixture during the mixing operation, and the entrained air bubbles are Fine unevenness was formed on the surface of the denture base after hardening, causing stains and discoloration of the denture over time.

[0006]

Accordingly, the present invention provides a paste having the same consistency as a rice cake which does not require kneading of a liquid and a powder at the time of use, and has excellent operability and odor. In addition to reducing irritancy, after curing, it has a large elastic energy compared to conventional denture base resin material, has moderate hardness and tenacity, and does not easily break when subjected to impact or stress Another object of the present invention is to develop a denture base resin material which does not cause stains or discoloration of the denture even during long-term use.

[0007]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventors have found that an alkyl (meth) acrylate homopolymer is contained in a polymerizable monomer having at least one unsaturated double bond. , An alkyl (meth) acrylate copolymer, and a part of at least one polymer selected from an alkyl (meth) acrylate / styrene copolymer are dissolved in advance, and a thermal polymerization catalyst and / or a photopolymerization are added thereto. By blending the catalyst, it is possible to obtain a denture base resin material that is excellent in operability and has no odor or irritation in a one-paste form that maintains the same consistency as a rice cake until polymerized by heat or light. The cured product has a large elastic energy, has moderate hardness and toughness, does not easily break due to impact or stress, and has no risk of contamination or discoloration due to air bubbles. The present invention has been completed by investigation that can be obtained.

[0008]

DETAILED DESCRIPTION OF THE INVENTION That is, the resin material for denture base according to the present invention comprises (A) a polymerizable monomer having at least one unsaturated double bond, (B) an alkyl (meth) acrylate homopolymer, At least one polymer selected from an alkyl (meth) acrylate copolymer and an alkyl (meth) acrylate / styrene copolymer is mixed with (C) a thermal polymerization catalyst and / or a photopolymerization catalyst. And (B) at least a part of which is dissolved in the component (A).

Among them, (A) 20 to 95 parts by weight of a polymerizable monomer having at least one unsaturated double bond (B) an alkyl (meth) acrylate homopolymer, an alkyl (meth) acrylate copolymer, an alkyl ( At least one polymer selected from meth) acrylate / styrene copolymers; 5 to 80 parts by weight of (C) a thermal polymerization catalyst and / or 0.01 to 5 parts by weight of a photopolymerization catalyst; The denture base resin material is preferably characterized in that at least 20% by weight of the component (B) is dissolved in the component (A).

The polymerizable monomer having at least one unsaturated double bond as the component (A) dissolves a part or all of the polymer as the component (B) to form the polymer for a denture base according to the present invention. It is a component necessary for changing the form of the resin material from a liquid and a powder that required a conventional mixing operation to a paste having the same consistency as a rice cake with good operability. Further, it functions effectively to secure the strength of the resin material for denture base after polymerization and curing, and to improve the long-term stability of the cured product. As such a polymerizable monomer, at least one methacrylate monomer selected from 1,6-hexanediol dimethacrylate, ethylene glycol dimethacrylate, and trimethylolpropane trimethacrylate is preferably used to improve elastic energy. There is an effect that a hardened body that is hard to be damaged can be obtained. Also,
Since these methacrylate monomers have low volatility, the storage stability of the denture base resin material is increased, and a denture base resin composition with lower odor and less irritation can be obtained. When the amount of such a polymerizable monomer is less than 20 parts by weight, it becomes difficult to dissolve the polymer as the component (B) in the denture base resin material, and when the amount exceeds 95 parts by weight, Tends to make the denture base resin material sticky. Especially, it is preferable that it is 40-80 weight part.

At least one polymer selected from the group consisting of an alkyl (meth) acrylate homopolymer, an alkyl (meth) acrylate copolymer, and an alkyl (meth) acrylate / styrene copolymer, which is the component (B), It is a polymer which is used by being partially dissolved in the polymerizable monomer which is the component (A) in advance. Examples of such a polymer include methyl (meth) acrylate, ethyl (meth) acrylate, butyl (meth) acrylate, isobutyl (meth) acrylate, tertiary butyl (meth) acrylate, ethylhexyl (meth) acrylate, lauryl (meth) Acrylate, dodecyl (meth) acrylate, stearyl (meth) acrylate, cyclohexyl (meth) acrylate, benzyl (meth) acrylate, isobornyl (meth) acrylate, glycidyl (meth) acrylate, hydroxyethyl (meth) acrylate, hydroxypropyl (meth) Acrylate,
Use is made of homopolymers or copolymers of methoxyethyl (meth) acrylate, ethoxyethyl (meth) acrylate, and at least one polymer selected from copolymers of these alkyl (meth) acrylates and styrene. I can do it. Among them, methyl (meth) acrylate homopolymer, ethyl (meth) acrylate homopolymer, butyl methacrylate homopolymer, isobutyl methacrylate homopolymer having a solubility in the polymerizable monomer as the component (A) of 20% by weight or more. , Methyl (meth) acrylate / ethyl (meth) acrylate copolymer, methyl (meth) acrylate / butyl (meth) acrylate copolymer, methyl (meth) acrylate / isobutyl (meth) acrylate copolymer, methyl (meth)
It is preferable to use at least one polymer selected from acrylate / styrene copolymers. When the amount of these polymers is less than 5 parts by weight, the fluidity of the composition before curing becomes high, and when it exceeds 80 parts by weight, the amount of the polymer becomes too large and the viscosity becomes high, and the dough shape is maintained. This tends to be difficult, and the operability of filling and lining tends to decrease. Especially, it is preferable that it is 20-60 weight part.

The thermopolymerization catalyst and / or photopolymerization catalyst as the component (C) is blended for polymerizing and curing the denture base resin material according to the present invention, and is used for producing dentures and for lining dentures by an indirect method. Use a thermal polymerization catalyst to heat and polymerize and cure the denture base resin material in the case of heating, and photopolymerize to polymerize and cure by irradiating light, such as in the case of denture lining by the direct method. A catalyst is used. It is needless to say that a thermal polymerization catalyst and a photopolymerization catalyst can be used in combination. It is appropriate to use 0.01 to 5 parts by weight of such a thermal polymerization catalyst and / or a photopolymerization catalyst.
If the amount is less than 1 part by weight, it is difficult to sufficiently polymerize and cure the denture base resin material, and if it exceeds 5 parts by weight, the stability of the composition before curing tends to be impaired.

As the thermal polymerization catalyst, aromatic diacyl peroxides and peroxyesters which are regarded as esters of perbenzoic acid can be used. For example, benzoyl peroxide, 2,4-dichlorobenzene Benzoyl peroxide, m-tolyl peroxide, t-

It is also possible to use a combination of the above. Examples of the reducing agent include tertiary amines represented by N, N-dimethyl-p-toluidine, triethanolamine, methyl 4-dimethylaminobenzoate, ethyl 4-dimethylaminobenzoate, and sodium sulfinate. Derivatives, organometallic compounds and the like can be mentioned.

The denture base resin material according to the present invention can be added with a filler as a component (D), if necessary, to improve the strength of the cured product. As the filler as the component (D), an inorganic filler is usually used, and specifically, glasses such as silicon dioxide, barium glass, alumina glass, and potassium glass, synthetic zeolite, calcium phosphate, feldspar, and silicate There are powders such as aluminum, calcium silicate, magnesium carbonate, and quartz.
These inorganic fillers may be surface-treated with γ-methacryloxypropyltrimethoxysilane, vinyltrichlorosilane, vinyltriethoxysilane, vinyltrimethoxysilane, vinyltriacetoxysilane, vinyltri (methoxyethoxy) silane, or the like. . In addition, the above-mentioned inorganic filler is mixed with a polymerizable monomer in advance, cured, and then pulverized. A so-called organic-inorganic composite filler or a polymer powder having no solubility in the polymerizable monomer is also used as the filler. Can be done. It is appropriate that the compounding amount of such a filler is 30 parts by weight or less, and if it exceeds 30 parts by weight, the paste becomes hard and the operability decreases. Further, the resin material for denture base according to the present invention, if necessary, a known polymerization inhibitor, an ultraviolet absorber, a plasticizer, a pigment for coloring, an antioxidant, an antibacterial agent, a surfactant and the like are added. Is also good.

The resin material for denture base according to the present invention has the same consistency as a rice cake obtained by mixing and kneading an appropriate amount of a liquid and powder of a conventional resin material for denture base, and leaving it to stand for a certain period of time. It is provided in the form of a paste which has a natural flow when it is at rest and hardly flows when producing or lining a denture. Instead, it is provided in the form of a paste that can be easily shaped with fingers or the like. In addition, the denture base resin material according to the present invention is applied to the production of a base plate, the repair of a denture, the provisional prosthesis, etc. by applying the property of high elastic energy in addition to the production of the denture and the lining of the denture. Can be used for a wide range of applications.
