Definitions
- Primer and kit consisting of primer and dental material
- the present invention relates to a primer for binding dental restoratives to dentine and / or tooth enamel, which contains a polymerizable (meth) acrylate or (meth) acrylamide monomer (i) at least one acidic group such as a phosphoric acid group and with (ii) at least a hydrophilic group such as a terminal hydroxy group or two polymerizable (meth) acrylate or (meth) acrylamide monomers of which one (i) has at least one acidic group and one (ii) has at least one hydrophilic group, one of which is polymerizable (meth) acrylate - or (meth) acrylamide monomers (i) and / or (ii) or another polymerizable (meth) acrylate or (meth) acrylamide monomer (iii) a 3,4,5,6,7,8, 9, 10-polyfunctionality, in particular in the form of preferably terminal, (meth) acrylate, (meth) acrylamide and / or
- polymerizable dental materials are often used. It is crucial for the quality of the result of the restored tooth that the aesthetic and functional requirements are met. From an aesthetic point of view, these dental materials must therefore not be visually distinguishable from natural tooth substance. In addition, however, they must also be sufficiently hard and the construction materials used must be attached to the natural tooth parts in such a way that the applied dental materials withstand the high forces they are exposed to when chewing.
- the polymerizable dental materials used to build up missing tooth substance are usually referred to as core build-up materials. Preferably used in this hydrophobic methacrylate monomers.
- stump building materials are present in paste form so that the dentist can build and model them in the patient's mouth.
- Such a model is usually applied in several layers and, after application, hardened, i.e. polymerized, layer by layer.
- this procedure is very time-consuming due to the multiple curing steps.
- polymerizable dental materials are also used in what are known as polymerizable composite cements. These cements are used to fix dental crowns and other dental prosthesis materials.
- polymerizable dental materials are also used as so-called bulk-fill composites.
- tooth cavities i.e. the spaces created by fleas after the removal of caries, are filled with the material.
- one of the many requirements placed on the polymerizable dental material is that a firm connection between the applied material and the natural tooth substance must be established, which ensures years of stability under the considerable mechanical requirements.
- a fluffing can be achieved by using adhesives (dental bonding agents), the adhesives on the tooth substance leading to better wetting and thus also to better flapping of the applied material.
- adhesives dental bonding agents
- three different mechanisms of action are required for this.
- such adhesives therefore had three components, which initiated different mechanisms of action one after the other in three steps.
- the natural tooth substance is etched by means of the first component, whereby the surface of the natural tooth substance, in particular also the tooth enamel, is roughened.
- the etching removes minerals from the collagen composite of the natural tooth substance, so that the collagen fibers essentially remain on the tooth surface.
- 35% by weight of phosphoric acid was usually used, which is applied to the natural tooth substance. The acid must then be removed by rinsing with water and then drying with air.
- the adhesion between the applied dental material and the natural tooth substance must be ensured.
- the etched tooth surface is coated with a so-called primer.
- This usually contains hydrophilic monomers, which can penetrate the exposed collagen-fiber composite.
- the primer has to be cured.
- a third step it must then be ensured that there is sufficient adhesion between the primer and the polymerizable dental material. This is problematic because, as described, the primer has hydrophilic monomers, but the dental material has hydrophobic monomers. Therefore, a further coating, a so-called bonding, must first be applied in order to achieve sufficient adhesion between the polymerizable dental material and the natural tooth substance.
- a particular disadvantage of the method described is the long treatment time due to the three separate steps.
- the different substances must be stored in different packaging and the risk of contamination and mix-up is increased.
- Products have already been developed in the past which combine one or more of the above-mentioned steps in one substance or a substance mixture, so that at least one step is omitted.
- the etching is carried out first and then a product is applied which comprises both hydrophilic and hydrophobic monomers and therefore combines the function of primer and bonding in itself.
- the etching can be combined with the primer, which is usually done in such a way that the hydrophilic monomers of the primer have phosphoric acid groups which etch the natural tooth substance. The substance required for bonding is then applied separately.
- the curing of the polymerizable dental materials is a complex process in itself:
- the polymerizable dental materials to be applied must be able to cure at moderate temperatures, since they are used in the patient's mouth.
- redox initiators are therefore used, which accelerate the curing process at temperatures of around 37 ° C.
- a redox initiator system is used which comprises a per-compound together with a co-initiator.
- the per compound is presented as a so-called catalyst paste in a first paste and the co-initiator in the so-called base paste in a second paste.
- the dental compound and co-initiator are brought together by mixing the pastes, so that a redox reaction takes place, which supplies the radicals required for polymerizing the organic monomers contained in the dental material.
- the pastes are stored separately from one another in order to ensure high storage stability.
- dental materials with an initiator system made of inorganic peroxides for example sodium or potassium peroxide sulfate in combination with an alkali or alkaline earth metal toluenesulfinate or an alkali or alkaline earth metal sulfite can be found in WO 2014/033280 A1.
- light-curing dental materials can also be used which have a photoinitiator.
- the disadvantage here is that the treating dentist has to apply these materials in thin layers, since the irradiated light cannot penetrate into deeper layers of the dental material. In the individual layers are modeled and cured with light in the meantime, the treatment time is significantly extended.
- EP 2 409 997 A1 describes a composition which penetrates the tooth substance and uses the moisture contained in the tooth substance to accelerate it To achieve curing of the dental material.
- the composition described comprises a monomer mixture, an inorganic peroxide, a reducing agent and other polymerization accelerators.
- the polymerization accelerator is dissolved by the moisture on the surface of the tooth substance, whereby the polymerization hardening at the adhesive interface and within the hardenable composition is improved.
- Be accelerator examples include sulfites but also ammonium salts such as the tetramethylammonium salt and the tetraethylammonium salt of benzenesulfonic acid.
- the polymerization accelerator is usually present in the base paste.
- EP 1 780 223 B1 describes an adhesive for the dental sector, a polymerization accelerator, namely a water-soluble sulfite, being added as an additional co-initiator.
- the sulfite is dispersed in the polymerizable monomer and dissolved at the interface with the natural tooth substance by moisture in the tooth. Due to the additional reducing effect of the sulfite, there is accelerated hardening of the polymerizable dental material at the interface between adhesive and polymerizable dental material.
- EP 2 554 154 A1 describes an adhesive and a curable composition in the form of a core build-up material with a high level of adhesion and durability.
- the adhesive includes a monomer mixture, water and a amine-based, sulfur-free reducing agent.
- the core build-up material also comprises a monomer mixture, a water-soluble, sulfur-containing reducing agent, an organic peroxide and an amine-based, sulfur-free reducing agent.
- DE 10 2015 103 427 describes a composition that is intended to ensure that there is sufficient curing both within the polymerizable dental material and at the interface with adhesives, in particular all-in-one adhesives.
- the object of the present invention to provide a primer to which the polymerizable dental material can be applied directly.
- the task is to provide a kit made of primer and polymerizable dental material, which is exactly matched to one another and thus ensures simplified processing with very good adhesion conditions at the same time.
- Such an aqueous primer composition is self-etching and self-priming. It has a polymerizable (meth) acrylate or (meth) acrylamide monomer with (i) at least one acidic group such as a phosphoric acid group and with (ii) at least one hydrophilic group such as a terminal hydroxyl group or two polymerizable (meth) acrylate or (meth) acrylamide monomers of which one (i) at least one acidic group and one (ii) at least one hydrophilic group on.

- This polyfunctionality is preferably an at least three-fold polyfunctionality, particularly preferably a 3-, 4-, 5-, 6-, 7-, 8-, 9- or 10-fold polyfunctionality. This polyfunctionality lies in the ability to polymerize.
- This primer composition is also characterized by the absence of the following substances: photoinitiators, vanadium compounds as polymerization catalysts, in particular in the form of organometallic vanadium compounds, e.g. vanadyl (V) derivatives, aromatic amines, and sulfinates and sulfonates, especially aromatic sulfonates such as sodium 4-toluenesulfonate.
- the primer composition according to the invention is characterized by the absence of an organic solvent.
- polyfunctionality in the context of the invention relates to the ability to polymerize and thus to crosslink density.
- a 3-polyfunctional monomer has three polymerizable groups.
- This composite composition has the ability to act as a reducing agent (sodium sulfite), which can start a polymerization reaction by diffusing into the claimed primer composition after it has been applied.
- the polymerization is therefore no longer started by a catalyst and / or an initiator which is contained in the composition itself, but rather is rather based on mass transport, in particular based on diffusion. It is consequently possible for the dentist, even without the risk of premature hardening, to prepare the tooth for the application of the dental material, then to apply the dental material and to achieve hardening of the entire system in a single step.

- adhesion values even after thermocycling are still above a value of> 10 MPa with a variance of 4 MPa.
- Such a system particularly preferably has an adhesion value of> 12 MPa with a variance of 4 MPa.
- a system in which the adhesion value does not deviate by more than a variance of 4 MPa is very preferred.

- the invention is also based on the object of also providing a kit in which a primer according to the invention is used together with a pasty two-component composite and thereby optimal adhesion results can be achieved.
- such a kit has a polymerizable dental material.
- the polymerizable dental material contains at least one catalyst paste (A) and at least one base paste (B).
- the catalyst paste comprises at least one organic peroxygen compound and at least one filler.
- the base paste contains at least one radically polymerizable organic (meth) acrylic monomer, at least one filler, a co-initiator of the free radical polymerization and at least one salt-like, water-soluble and powdery reducing agent (hereinafter also: reducing agent) dispersed in the base paste (B) .
- At least one phase transfer catalyst is provided in the at least one catalyst paste and / or the at least one base paste, which is an ammonium, a phosphonium and / or a sulfonium salt which contains an inorganic or organic anion, preferably with the exception of anions Sulfinic acids or sulfonic acids.
- phase transfer catalyst improves the adhesion to the tooth substance. This can be explained by the fact that the salt-like, water-soluble and powdery reducing agent is dissolved at the interface with the primer and can then diffuse through the phase transfer catalyst at the interface between the composite and the primer in order to accelerate the polymerization through reaction with the Achieve per-oxygen connection. Due to the division of the polymerizable dental material into at least one catalyst paste and at least one base paste, high storage stability is achieved. By mixing these individual components, the polymerizable dental material is produced, which quickly hardens under oral conditions (appropriate temperature and humidity).
- the proportion of the phase transfer catalyst in the catalyst paste and / or the base paste, based on the total mass of the catalyst paste and / or the base paste, is preferably 0.01 to 5% by weight, preferably 0.01 to 2% by weight, particularly preferred 0.05 to 1% by weight and very particularly preferably 0.05 to 0.5% by weight.
- the mentioned weight fraction of the phase transfer catalyst in the catalyst paste and / or the base paste based on the total mass of the catalyst paste and / or the base paste must be chosen so low that the curing of the polymerizable dental material does not proceed so quickly that processing of the dental material is difficult or even prevented. At the same time, the weight percentage mentioned must be selected to be so high that the polymerization of the dental material is accelerated as intended within the dental material mass.
- the phase transfer catalyst is contained in the catalyst paste. This has been found to be particularly favorable in terms of storage stability, since potential activation of the reducing agent present in the base paste with the phase transfer catalyst and subsequent reaction of the reducing agent with air oxygen can be prevented as described above.
- Drying agents can be added for further stabilization.

- Iron-containing primer (Fe) In the manner described, 20 wt .-% MDP, 47.0 wt .-% HEMA, 0.1 wt .-% BHT, 0.2 wt .-% 2- (dimethylamino) ethyl methyl acrylate and 2% by weight of trimethylpropane trimethacrylate as trimethacrylate and 0.7% by weight of iron (III) EDTA, first alone and then mixed together with 30% by weight of water. The primers were then tested with the previously described base pastes 2B and 3B as well as the corresponding catalyst pastes 2 and 3. The results are summarized in Table 5 below.
