- dental MTA Mineral Trioxide Aggregate
- industrial shotcrete may be useful.
- dental MTA has been introduced in the form of a mixture of Portland cement and radiopaque material by Torabinejad et al.
- Concerning the construction of such an MTA reference may be made to US 2005/0263036 and US 5,415,547 (the content of which is to be considered as incorporated by reference in its entirety).
- MTA is mainly used for root canal filling, pulp demodulation, and root perforation repair.
- the main component of Portland cement is tricalcium silicate (C3S), dicalcium silicate (C2S), tricalcium aluminate, tetra Calcium aluminoferrite (C4AF) and the like.
- C3S tricalcium silicate
- C2S dicalcium silicate
- C4AF tricalcium aluminate
- C4AF tetra Calcium aluminoferrite
- calcium sulphate may be added to inhibit the rapid hydration of the initial calcium aluminate.
- MTA acts at the site where body fluids, saliva, and other liquids are present, it is essential that the MTA be cured quickly in order to be stably cured and sealed.
- MTA made using conventional Portland cement has a long curing time of about 3 hours and thus lacks washing resistance and poor operability.
- MTA has been introduced to reduce the curing time by 57 minutes by adding calcium chloride to Portland cement.
- the above curing time is still long in clinical terms.
- the rapid hardening of the MTA becomes more important when the procedure time needs to be shortened to 11 minutes or less, such as when dental replanting is performed.
- a short curing time of 10 minutes or less is desired from the viewpoint that it is necessary to reduce the number of procedures to reduce the number of visits to the patient and to maximize the convenience of the procedure.
- the present invention aims to solve all of the above-mentioned problems of the prior art.
- the present invention is cured within 10 minutes, it is convenient for (dental) medical use, effectively inhibits the penetration of body fluids and saliva during use, and biological tissue constructs such as tertiary dentin, alveolar tinea, hydroxyapatite It is an object of the present invention to provide a biocompatible hydraulic binder composition by promoting regeneration thereof.

- C3A tricalcium aluminate
- C12A7 dodecacalcium heptaaluminate
- compositions for implementing the present invention are further provided.
- biocompatible superhard hydraulic binder composition that cures within 10 minutes.
- a basic method of preparing the biocompatible superhard cemented binder composition according to embodiments of the present invention may be as follows.
- C3A is commonly found in common (white) Portland cements. To this Portland cement (which may be powdered), C12A7 (which may be powdered) and calcium hydroxide (which may be powdered) may be added, if necessary, to prepare a composition of the present invention. have.
- Portland cement is already known to be produced by firing and processing clinkers for cement production.
- all the clinker for producing cement may be calcined at a temperature before conversion to C3A so that a predetermined amount of C3A and C12A7 is present in the portland cement. That is, the complete firing temperature for a general portland cement is 1450 ° C, and by firing at a temperature of 800 ° C to 1250 ° C, it is possible to make C3A and C12A7 coexist within the resulting portland cement.
- calcium hydroxide which may be powdered
- may be added thereto which may be powdered
- Calcium aluminate is a continuous solid solution of calcium oxide (CaO) and alumina (Al 2 O 3 ) and has various mineral properties depending on the composition ratio. Often calcium oxide is expressed as C and alumina is expressed as A (although this expression is followed in many ways). C3A or other calcium present in the Portland cement aluminate (CA, CA2, C12A7, etc.) eth- Lin ZUID; crude stiffness by creating a hydrated mineral of (Ettringite 3CaO ⁇ Al 2 O 3 ⁇ 3CaSO 4 ⁇ 32H 2 O) Can be represented.
- calcium aluminate reacts violently with gypsum components eluted from water or portland cement to produce needle-shaped ethrinzite crystals, which bind particles of cement or aggregate. As a result, rapid condensation characteristics are exhibited.
- ethrinzite can be produced by the reaction of the following scheme:
- the ethrinzite formation scheme can be as follows:
- the mono-sulfate (monosulfate) hydrate (3CaO ⁇ Al 2 O 3 ⁇ CaSO 4 ⁇ 12H 2 O) having a relatively small crystal form is also produced.
- Hydration of C3A and C12A7 as described above is important for the strength development of the cured product produced from the composition of the present invention (particularly the expression of the initial strength of the cured product).
- the ethrinzite mentioned above is a hydrate containing 32 moles of water per molecule, so that the water around the composition of the present invention is rapidly fixed and gelled and crosslinked with needle-shaped crystals without covering the portland cement particles. It has the advantage that it does not interfere with the hydration reaction of subsequent Portland cement particles because it forms.
- alite which can be included in the composition of the present invention, becomes calcium silicate hydrate (CSH) While filling the voids between linzite, it is possible to form a more compact hardened body.
- a hardened body is a permanent hardened body without dissolution phenomenon in the long term because it has a water resistance that does not dissolve or loosen in water.
- C12A7 together with C3A forms ethrinite to achieve the required curing. Let's take a closer look at these C12A7.
- C12A7 reacts rapidly with water and generates high heat, producing hydrates such as 3CaO ⁇ Al 2 O 3 ⁇ 6H 2 O and aluminum hydroxide gels.
- Aluminum hydroxide is more advantageous because it has superior antioxidative properties than calcium hydroxide.
- C12A7 is rarely found in nature as a mineral mayenite. It is also sometimes present in natural cement. However, as mentioned above, it may be desirable for C12A7 to be produced by low temperature firing of Portland cement.
- C12A7 can be present at 1.5 times or less of C3A by weight.
- C12A7 may be present at one or less times C3A. More preferably, C12A7 may be present from 0.5 to 1 times C3A. Most preferably, C12A7 may be present in the same amount as C3A.
- the average particle size of calcium hydroxide is preferably 15 microns or less. More preferred is an average particle size of 10 microns or less. Most preferred is an average particle size of 5 microns or less.
- Calcium hydroxide may act to shorten the curing time by increasing the concentration of the hydration reactant during the initial hydration reaction to increase the rate of calcium aluminate to produce ethrinite.
- This calcium hydroxide is actually a useful material that has been in the spotlight in dental preservation for a long time. Only calcium hydroxide can be used to treat dental caries or to protect the exposed pulp from accidents. Overall, maintaining calcium hydroxide in insoluble stable compounds can increase the safety and efficacy of the procedure.
- calcium hydroxide is preferably included in 3% or more and 7% or less of Portland cement in terms of weight in the composition of the present invention.
- Gypsum components (primarily anhydrides, hemihydrates or dihydrates of calcium sulfate)
- the gypsum component is important for the production of etrinzite.
- Such gypsum components are usually anhydrides, hemihydrates or dihydrates of calcium sulfate.
- the gypsum component may be mainly represented as calcium sulfate hemihydrate (ie, gypsum).
- the gypsum component may appear as anhydride or dihydrate of calcium sulfate.
- the gypsum component may be comprised between 15 and 200% based on the weight of the alumina component in the composition of the present invention.
- the weight ratio of the gypsum component to the alumina component is less than 15%, the rate of formation of ethrinzite is lowered and the amount thereof is too small, and the amount of ethrinza produced by the absolute lack of SO 4 2- ions is generated. This is because the strength of the cured product is also lowered in the process of decomposing into disulfide monosulfate.
- the weight ratio of the gypsum component to the alumina component is more than 200%, the strength development of the cured body is delayed due to the recrystallization of hydrated gypsum due to excessive gypsum content or the relatively small amount of alumina component.
- ethrinzite which is essential for the curing reaction of the present invention
- the layer of ethrinzite is the surface of the particles of the C3A particles.
- Calcium silicate components ie, C3S, C2S, etc.
- CSH gels are produced while the next hydration of C3A is delayed. It is possible to prevent as much as possible from the generation of disadvantageous curing such as sulfate hydrate.
- a condensation accelerator for promoting the hydration reaction may be further included in the composition of the present invention.
- a coagulation accelerator lithium carbonate, sodium carbonate, sodium sulfate, magnesium sulfate, aluminum sulfate and the like can be used.
- At least one coagulation accelerator may be selected from the group consisting of these, in particular sodium carbonate may be a preferred coagulation accelerator.
- the content of the coagulation accelerator is preferably 7 parts by weight or less per 100 parts by weight of C12A7 (when the coagulation accelerator is sodium carbonate). When 7 parts by weight is exceeded, there is a disadvantage in that the durability of the cured product is reduced.
- a pozzolanic substance is a substance which can react with calcium hydroxide to cause a known pozzolanic reaction (e.g., natural pozzolanic substance from volcanic ash, tuff, silicate, diatomaceous earth, fly ash, calcined clay, silica gel, silica fume, etc.). Artificial pozzolanic) may be referred to collectively.
- Such pozzolanic reactions may contribute to the suppression of heat generation due to the quenching of calcium aluminate, especially with respect to the compositions of the invention characterized by having a short curing time.
- the insoluble microcured product produced by the pozzolanic reaction increases the long-term strength of the cured product formed by the composition of the present invention, and fills the pores of the cured product so that the sealing property is good, contributing to suppressing the penetration of bacteria and the like. do.
- it is excellent in chemical resistance, flame resistance, and the like and is particularly suitable in the oral environment.
- pozzolanic materials can be employed in various ways, of which particular points will be discussed below. The following may be adopted in duplicate.
- Volcanic glass containing silica, alumina, etc. is a glass in which magma ejected by volcanic eruption is quenched in the air to have a porous structure having a large amorphous surface area. This structure causes volcanic glass to have high pozzolanic reactivity.
- Volcanic glass can be used without additional heat treatment to enhance the pozzolanic properties, but clay pozzolanic materials are less pozzolanic in reactivity unless they are thermally treated to destroy the crystal structure of clay minerals. Therefore, it is possible to use an amorphous structure by calcining the clay pozzolanic material at a temperature of about 600 to 900 ° C or irregularly forming a silica structure to an alumina structure. This may also be called calcined clay.
- Silica fume is a representative example of siliceous pozzolanic materials. It consists of about 30% or more of spherical particles, the size of most of which is 1 micron or less, and the average is about 0.1 micron. It consists of at least 90% amorphous silica. It produces a very high pozzolanic reaction because of its very high powder and high amount of silica.
- nano Al 2 O 3 particles ie nano alumina particles
- amorphous or glassy alumina can be used. Such alumina increases pozzolanic reactivity.
- nano Al 2 O 3 having a high purity of 99.9% and a high Blaine fineness value (for example, 60 m 2 / g). . It may be added until it shows a weight ratio of about 2% with respect to the composition of the present invention. Although adding until it shows about 1% weight ratio shows a considerable strength improvement effect, when it exceeds 2%, there exists a disadvantage that operability worsens.
- Nano SiO 2 (ie, nano silica) is a more potent pozzolanic material than silica fume, and a small amount of up to 3% by weight of the composition is sufficient to show a sufficient effect.
- the smaller the particle size of the material the more pronounced the effect of strength enhancement.
- composition of the present invention according to the judgment of those skilled in the art, a known radiopaque material may be added in an appropriate amount depending on the specific use.
- compositions of the present invention by various methods will be described with respect to conducting an experiment comparing the curing time of each prepared composition.
- the present inventors manufactured the hydraulic binder composition using the following components or compositions.
- Case 1 9 parts by weight of white Portland cement, 1 part by weight of C12A7, 0.5 parts by weight of calcium hydroxide
- Case 2 9.5 parts by weight of white Portland cement, 0.5 parts by weight of C12A7, 0.5 parts by weight of calcium hydroxide
- Case 3 36 parts by weight of white Portland cement, 4 parts by weight of C12A7, 1 part by weight of calcium hydroxide, 2 parts by weight of calcium sulfate (0.5 parts by weight of gypsum)
- compositions of the present invention by various methods will be described with respect to the experiments performed to compare the biocompatibility of each prepared composition.
- the biocompatibility of the hydraulic binder composition of 0 to 3 was confirmed by observing the activity of alkaline phosphatase and the degree of gene expression related to mineralization.
