Definitions
- the field of the invention is that of dental compositions. More specifically, the dental compositions developed in the context of the present invention can be used for the production of dental prostheses and for dental restoration.
- These dental compositions are conventionally epoxy resins, or photopolymerizable silicones or acrylate resins which can be polymerized by the radical route. These compositions also include particulate reinforcing fillers (e.g. hydrophobized silica), photoinitiators and optionally photosensitizers or even other functional additives such as pigments or stabilizers. Once mixed, these compositions are shaped and then photocrosslinked into a mass of structure similar to that of the teeth.
- the filler consists of very fine particles ( ⁇ 0.01 to 5 ⁇ m) and a large specific surface, is a limiting factor in its rate of incorporation into the resin.
- the latter has a limited absorption capacity.
- the charge rates of such compositions rarely reach more than 45% by volume. This therefore penalizes the mechanical reinforcement function assigned to the particulate load.
- the dental compositions are formulated with reinforcing fillers such as mineral glasses or very low particle size combustion silicas, including surface silanols and / or the residual water react with the cationic functions not allowing the storage of the compositions.
- US-B-6,306,926 relates to dental compositions based on epoxy resins (eg UVR ® 6105, EPON ® 828, GY281 ®), oxetane, or vinyl ether, among others, the polymerizable / crosslinkable cationically and under irradiation, and optionally radical-polymerizable (meth) acrylate resins.
- epoxy resins eg UVR ® 6105, EPON ® 828, GY281 ®
- these compositions comprise a microparticulate, radio-opaque mineral filler, which is selected from the following metal compounds: oxides, halides, borate phosphates, silicates, carbonates, germanates, tetrafluoroborates, hexafluorophosphates, having an isoelectric point less than 7
- This composition is such that its Barcol hardness is at least 10, after 30 min of cationic polymerization at 25 ° C.
- These resins have the disadvantage of not being perfectly transparent to actinic radiation activating the polymerization by UV-visible radiation, which is harmful to the reaction kinetics and therefore limits the possibilities of obtaining very thick photocrosslinked materials.
- Patent application FR-A-2 784 025 aims to remedy this problem by proposing dental compositions based on polymerizable / crosslinkable silicone resins, cationically and under irradiation whether or not followed by thermal post-crosslinking.
- These silicone resins have oxirane (epoxy, oxetane ...) or vinyl ether functionalities.
- Such compositions comprise: - one or more crosslinkable and / or polymerizable polydimethylsiloxanes cationically and carrying at least one of their ends of the reactive functions of formula:
- These dental compositions are intended for the manufacture of prostheses or dental appliances and for dental restoration.
- These silicones have the advantage compared to organic resins crosslinking cationically to be very transparent to UV-visible light and therefore allow obtaining very thick materials (several millimeters thick) photocrosslinked in a very short time (less than a minute) with a UV lamp emitting in the visible range> 400 nm.
- these silicones are formulated with Lewis or Bronsted acid reinforcing fillers, such as ground glass or very small particle size combustion silicas, including surface silanols and / or residual water, react with the cationic functions. Such silicone formulations are therefore unstable on storage.
- these silicones are formulated with photosensitizers of the thioxanthone type, a great chromatic variation is observed during exposure with a view to photocrosslinking. This results in a pinkish coloration of the finished product (after exposure) which is undesirable from an aesthetic point of view.
- radical dental compositions is in no way transposable to cationic silicone-based dental compositions.
- the dispersants R - [- CO- (CH 2 ) 5 -O-] n -PO 3 H 2 are not suitable for cationic compositions, in particular because they contain an important RPO 3 H 2 acid residue which reacts in the presence of oxirane functions and harms the stability of the composition.
- the prior art does not provide a satisfactory solution to the double problem of stabilization in storage of dental compositions based on polymerizable patterns cationically under UV (for example oxiranes) and dispersion of large amounts of fillers in resin.
- the prior art also does not provide a solution when the problem of residual coloring of dental compositions after crosslinking.
- One of the essential objectives of the present invention is therefore to remedy this by providing new dental compositions based on polymerizable patterns cationically under UV (for example oxiranes), not having the drawbacks of the prior art on the storage stability plan and the limited load rate.
- Another essential objective of the present invention is to provide new cationic, polymerizable and / or crosslinkable dental compositions in an oral environment, which are not only stable on storage and highly loaded (eg ⁇ 50%) but which also have the advantage of '' be very transparent to UV-visible light and therefore allow very thick materials (several millimeters thick) photocrosslinked to be obtained in a very short time (less than a minute) with a UV lamp emitting in the visible range > 400 nm.
- Another essential objective of the present invention is to provide new cationic dental compositions, polymerizable and / or crosslinkable in the oral environment, which are stable, highly charged (eg ⁇ 50%), easy to prepare and economical but also which do not exhibit the disadvantage of generating parasitic colorations after crosslinking.
