Background technology
Dental caries treatment work has a large amount of market demands to relevant dental filling material.Dentistry composite resin is because of having higher mechanical strength, advantage such as thermal coefficient of expansion is similar to tooth, and polishing performance is good, is insoluble to saliva, and color and luster and tooth are close and be widely used in the repairing filling of cavity.But the anti-wear performance and the toughness and tenacity of dentistry composite resin are still not ideal enough at present.
Dentistry composite resin also is called tooth section composite resin, and it is a kind of teeth repairing material that is combined by organic resin substrate and surface treated inorganic filler and initiator system, is widely used in directly and indirectly repairing of all kinds of dental defect.For a long time, for overcoming the disadvantage of traditional teeth repairing material-silver amalgam, people are seeking a kind of repair materials safely and effectively can replace silver amalgam always.It is that organic resin and adamantine bonding maintenance have found a kind of effective ways that Buonocore adopts phosphoric acid pretreatment facing the fifties, Bowen successfully synthesizes a kind of important resin monomer BIS-GMA with special construction and performance in the sixties, on this basis, dentistry composite resin is developed rapidly.Dentistry composite resin has become the requisite important materials of dental defect repairing and treating, runs neck and neck with silver amalgam.
Dentistry compound resin material is at present many to be configured to single paste type or two paste type for clinical use by manufacturer.The dentistry compound resin material of single paste prescription also claims visible-light curing composite resin (VLC), is that the visible light with specific wavelength and intensity comes initiated polymerization.The product in past mostly is ultraviolet light (UV) curing materials.Two paste type composite resin materials can be after mixing self-solidifying, also can after mixing, reach dual cure by using visible light.The composite resin prescription that occurs on the current international market has kind more than 50, and they can be divided into different classifications, and has bigger difference on composition and performance.Its composition introduction of the dentistry compound resin material that manufacturer announced is more rough usually, and important data then need could obtain by chemical analysis.The basic composition of dentistry compound resin material comprises: resinous substrates, inorganic filler, polymerizing curable cause material, polymerization inhibitor and coloring agent; The effect of resinous substrates is to give plasticity, curing characteristics and intensity, resinous substrates commonly used is the polyfunctional group methacrylate monomer, the polyfunctional group methacrylate monomer relates to miscellaneous similar chemical substance, actual polyfunctional group methacrylate monomer commonly used is the selection of having taken all factors into consideration the each side factor in the dentistry compound resin material, concrete example such as BIS-GMA, UDMA and TEGDMA, BIS-GMA wherein, UDMA or their combination have viscosity higher, and TEGDMA joins BIS-GMA for reducing viscosity as diluent, in UDMA or their combination; The effect of inorganic filler is to gain in strength and wearability, inorganic filler commonly used such as silica flour, silicon dioxide powder, glass dust; The effect that polymerizing curable causes material is the trigger monomer polymerizing curable, polymerizing curable causes material and generally includes initiator and coinitiator, described initiator and coinitiator can be respectively peroxide and tertiary amine for the situation of chemosetting, peroxide concrete example such as BPO, tertiary amine concrete example such as DHET, at present, the mode of visible-light curing is main flow gradually, for utilizing radiation of visible light to carry out the situation of resin solidification, described initiator and coinitiator can be respectively camphorquinone and tertiary amine; Inhibitor action is to keep effective life, and described polymerization inhibitor mostly is phenols; The effect of coloring agent is to give the natural teeth color and luster, described coloring agent such as titanium white, chrome yellow.The dummy suffix notation BIS-GMA acute pyogenic infection of finger tip bisphenol-A glycidyl methacrylate that above relates to; Dummy suffix notation UDMA acute pyogenic infection of finger tip carbamate double methyl methacrylate; Dummy suffix notation TEGDMA acute pyogenic infection of finger tip double methyl methacrylate triethylene glycol ester; Dummy suffix notation BPO acute pyogenic infection of finger tip benzoyl peroxide, benzoyl peroxide has another name called dibenzoyl peroxide; Dummy suffix notation DHET acute pyogenic infection of finger tip N, the N-dihydroxyethyl p-toluidine.More than the Chinese of cited various related substanceses and the art-recognized meanings of English alphabet dummy suffix notation indication, for the dental profession technical staff, its art-recognized meanings is known.
In each composition of dentistry composite resin, for amorphous granular is adopted in the inorganic filler of gaining in strength and wearability adds more, the effect that it can be brought into play in composite resin is similar to spheroidal particle, surface layer at the dentistry composite resin after polyreaction is solidified, faying face between amorphous granular and the resin matrix is less, anchor force thus a little less than, in friction process, peel off easily, this factor makes amorphous granular make a discount in the effect aspect the lifting dentistry composite resin wearability, on the other hand, in the dentistry composite resin body after solidifying, the rough approximation substantially of amorphous granular is in spheric pattern, also extracts toughening mechanisms some shortcomings have been arranged because of fully not taking into account for the Strengthening and Toughening contribution of dentistry composite resin.
Extract toughening mechanisms and come the Strengthening and Toughening dentistry composite resin for utilizing fully, in recent years, the glass fibre that draw ratio is very high, silicon carbide whisker, silicon nitride crystal whisker and aluminium borate whisker etc. are as considerable inorganic filler, obtain some research staff's concern, undoubtedly, the inorganic filler that this class draw ratio is very high is if can sneak into equably in the resin, benefiting of a front will be provided the Strengthening and Toughening of dentistry composite resin, but, the glass fibre that draw ratio is very high, silicon carbide whisker, silicon nitride crystal whisker and aluminium borate whisker etc. are difficult to sneak into equably in the resin matrix because of its inherent physics pattern, in other words, uniform mixing becomes and is difficult for the obstacle gone beyond together, this factor, make the glass fibre that draw ratio is very high, silicon carbide whisker, the application of inorganic material such as silicon nitride crystal whisker and aluminium borate whisker in dentistry composite resin can be not fully, put to good use all sidedly, about this point, in cavity is filled with the dentistry compound resin material field, show particularly evidently.
Summary of the invention
Technical problem to be solved by this invention is, demand the further technical development actual requirement of raising urgently at existing dentistry composite resin anti-wear performance and toughness and tenacity, develop a kind of new dental resin composition, this dental resin composition should be taken the raising of wearability into account, also to take into account and extract toughening mechanisms the front of Strengthening and Toughening is benefited, simultaneously, in preparation, produce in the stage of this dental resin composition, should be easily and other composition uniform mixing of compositions for increasing its relevant composition of inorganic filler that wearability and obdurability add therebetween, avoid occurring described mixing obstacle.
