Abstract
It is an object of the invention to provide a kind of especially polymerization shrinkage dental materials, dental materials compositions and dental prosthetic material little, that the most also can manufacture when solidification with cheap price.The dental materials of the present invention is characterised by, specific carbamate (methyl) acrylic compounds represented containing following formula (1).
Description
Technical field
The present invention relates to a kind of novel dental materials, dental materials compositions, dental prosthetic material and make this dentistry material
The solidfied material of material solidification.In detail, the present invention relates to a kind of containing novel carbamate (methyl) acrylic compounds
The dental materials of compound, comprise the dental materials compositions of this dental materials.
Background technology
In the past, its characteristic such as good curable and the transparency was utilized, with (methyl) acrylate free radical as representative
Polymerizable monomer is widely used in the various fields such as coating, plate making, optical material and dental materials.
Wherein, in dental materials field, the tooth used in the dental caries that is widely used in natural teeth, the reparation fractureed etc.
The dental prosthetic materials such as section's composite resin, for making dental composite resin and the bonding various dental adhesives of tooth,
And artificial tooth, dental plate material etc..
Dental composite resin is typically made up of polymerizable monomer, polymerization initiator and filler, as polymerizable monomer, from
From the viewpoint of safety, the mechanical strength of solidfied material, mar proof and aesthetic property etc. in organism, use radical polymerization
Multifunctional (methyl) acrylate of property.As multifunctional (methyl) acrylate, use 2, double (4-(the 3-methacryl of 2-
Epoxide-2-hydroxy propyloxy group) phenyl propane (being commonly referred to as Bis-GMA), dimethacrylate 2,2,4-tri-methyl hexamethylene is double
(2-carbamoyloxy ethyl) ester (being commonly referred to as UDMA), particularly Bis-GMA was proposed at tooth by Bowen first since 1962
Since application in section's material, the most still the polymerizable monomer as almost all of dental composite resin uses.
But, for dental composite resin, point out from clinical sites, the bending strength of solidfied material, elastic modelling quantity and
The minimizing of the polymerization shrinkage when minimizing of the raising of mar proof, water suction and color-shifting colorant, solidification is as natural teeth
The improvement leeway of the aspects such as the transparency and aesthetic property is big.Particularly polymerization shrinkage can cause because dental composite resin is from bonding plane
The generation of shrinkage joint peeled off and generate, becomes recurrent caries, plup stimulus, coloring, restoration come off etc. reason, the most strongly
Wish to be reduced as far as.It addition, in order to meet the high request to aesthetic property, and give x-ray imaging, multiple at dental
The filler of commonly used high index of refraction in resin, it is therefore desirable to give the transparency close with natural teeth, it is desirable to used
The refractive index of polymerizable monomer is high.And then, from from the viewpoint of intraoral durability (resistance to impact and broken resistance), uncommon
Prestige has high bending strength.
Minimizing for polymerization shrinkage, it is proposed that use the open loop that polymerization shrinkage is generally less than acrylic compounds to gather
The epoxide of conjunction property, oxetane compound (patent documentation 1 and patent documentation 2).By using these compounds, have
The tendency of polymerization shrinkage can be reduced, but because curing system is different, so needing the problems such as special priming paint (primer) the most very
Many.It addition, it is problematic from the viewpoint of aesthetic property and operability.
The loading of filler is improved to reduce polymerization shrinkage (patent documentation 3 and patent documentation 4) it addition, it is also proposed.So
And, because the shrinkage factor of monomer used is big, so its effect is limited.
Also proposed the low-shrinkage material (patent documentation 5) using siliceous (methyl) acrylate.But, this material
Synthesize loaded down with trivial details, leave problem at industry manufacture view.It addition, it is problematic from the viewpoint of the mechanical strength of solidfied material.
Accordingly, it would be desirable to have a kind of polymerization shrinkage when can be used for dental prosthetic material, solidification little, the most also can be with
The polymerizable monomer that cheap price manufactures.

It addition, dropping refers to the diisocyanate cpd of regulation is added the dropping container being connected with reaction vessel, logical
Overregulate flow, through the method that a certain amount of diisocyanate cpd is added reaction vessel by the regular hour.In contrast,
By in the baiting method in the lump of the diisocyanate cpd of regulation all blankings at short notice, according to (methyl) of hydroxyl
Acrylic compounds, the structure of diisocyanate cpd, molecular weight, the structure of reaction vessel, the shape of stirring vane, stir
Mixing the difference of speed etc., temperature can significantly raise, it is possible to is difficult to temperature control, and the crosslinking of diisocyanate cpd is anti-
Should be promoted, the increase of the viscosity of gained carbamate (methyl) acrylic compounds may be caused, according to circumstances
May cause the polymerization of polymerizable group, thus gelation.
(methyl) acrylic compounds of hydroxyl can also be dropped in diisocyanate cpd.Now, because of
For in most cases using (methyl) acrylic compounds of the hydroxyl of more amount compared with diisocyanate cpd,
So compared with the situation of dropping diisocyanate cpd, time for adding extends, and to carbamate (methyl) propylene
Acid compounds applies unnecessary thermal history, causes the polymerization of polymerizable group, and production efficiency is deteriorated sometimes.
Temperature in reaction system depends on the size of reaction vessel, structure etc., is not particularly limited, usually 20~120
DEG C, preferably 30~100 DEG C.If above 120 DEG C, then it may happen that polyreaction, possibly cannot obtain having desired
Carbamate (methyl) acrylic compounds of effect.If less than 20 DEG C, then the response time extends, and production efficiency may
Can be deteriorated.
Temperature when dropping starts is not particularly limited, usually 20~90 DEG C, preferably 30~80 DEG C.If less than 20
DEG C, then reaction needs a lot of times, may cause the decline of production efficiency.On the other hand, if above 90 DEG C, then have and send out
The probability of raw polyreaction, reaction (dropping) temperature may raise, and reaction becomes uncontrollable.
As long as rate of addition maintains the speed of the temperature in above-mentioned reaction system.
As long as time for adding meets the time of said temperature, usually 0.1~30 hour, preferably 0.1~5 is little
Time.If being shorter than 0.1 hour, then temperature may significantly raise, it is difficult to carries out temperature control.If it addition, be longer than 5 hours,
Then there is the tendency that the production efficiency of carbamate (methyl) acrylic compounds is deteriorated.
In operation (B), react in above-mentioned time for adding unclosed in the case of, can be as required after completion of dropwise addition
Continue reaction.This response time depends on reaction temperature, the size of reaction vessel, structure, time for adding etc., therefore without limit especially
Fixed, it is usually 1~30 hour with the summation of time for adding, preferably 1~20 hour.If being shorter than 1 hour, then react likely
It is not fully complete, if being longer than 30 hours, then carbamate (methyl) acrylic compounds may be applied unnecessary heat and go through
History, causes the polymerization of polymerizable group, may result in production efficiency variation, product price rising.
As long as the reaction temperature polymerizable group after completion of dropwise addition does not occur the temperature of thermal polymerization, indefinite, lead to
Often in the range of 20~120 DEG C, preferably in the range of 30~100 DEG C.If less than 20 DEG C, then the response time may prolong
Long, the decline of production efficiency may be caused.It addition, if above 120 DEG C, then it may happen that polyreaction, carbamic acid
Ester (methyl) acrylic compounds may colour.
As the confirmation method of the terminal of reaction, can enumerate and be surveyed by the assay method on the basis of JIS K15565.5
Determine the method for the content of the diisocyanate cpd in reaction product, use the analysis etc. of HPLC (high performance liquid chromatography).
Specifically, following method can be enumerated: taken out from reaction vessel by reaction product so that it is react with di-n-butylamine, use salt
Acid titrates unreacted amine, thus measures the content of the diisocyanate cpd in reaction product.Calculated by the method
Go out the content of diisocyanate cpd, by the content of diisocyanate cpd relative to weight 100 weight of reaction product
Amount % reaches the moment of below below 0.5 weight %, preferably 0.1 weight % as terminal.
<operation C>
After above-mentioned operation (B) terminates, there is operation (C) the most as required that carry out deodorize.By deodorize, can obtain
Good carbamate (methyl) acrylic compounds.
There is not the temperature of thermal polymerization in the temperature preferred polymeric group of operation (C), generally the scope of 20~120 DEG C
In, preferably in the range of 30~100 DEG C.If less than 20 DEG C, then deodorize is insufficient, may obtain foul smell and strongly and preserve
Carbamate (methyl) acrylic compounds of poor stability.It addition, if above 120 DEG C, then it may happen that be polymerized
Reaction, carbamate (methyl) acrylic compounds may colour.
The pressure of operation (C) is not particularly limited, generally in the range of 0.133~13.3kPa (1~100mmHg), preferably
