Definitions
- the invention relates to a kit for producing a dental restoration material for restoring teeth and dentures and for fastening dental material, and a restoration material that can be produced from the kit.
- a so-called dental material is often attached to a tooth surface or in a tooth cavity.
- This dental material can in particular be metallic, ceramic or plastic materials, for example inlays, crowns, fillings or the like. It is important to establish a good bond between the tooth and the dental material (filling or inlay), since marginal gap formation can occur if there is insufficient adhesion. Bacteria can penetrate into the marginal gap and cause secondary caries and / or damage the pulp.
- the invention thus relates to a kit for producing a dental restoration material which contains:
- an electron donor active in an acidic environment selected from the group consisting of sulfinic acid and its salts,
- the corresponding tooth surface or tooth cavity is first prepared with the primer for connection to the second main component of the kit, the polymerizable material.
- preparation of tooth surface or cavity encompasses both the etching and the priming of the tooth surface, as is known from EP-A-1 121 924.
- Priming involves establishing a good connection between the primer and the tooth surface, for example by penetrating the phosphoric acid ends arranged on the spacer sections of the molecules into the dentin tubules of the tooth substance.
- the primer ensures good mechanical adhesion to the tooth or denture surface.
- the steps of etching and priming can be carried out in one step.
- the primer contains phosphoric acid and / or phosphoric acid esters and / or diphosphates.
- phosphoric acid ester encompasses both mono-, di- and triesters of phosphoric acid and its salts.
- HPMA hydroxypropyl methacrylate
- Other suitable alcohol groups are particularly preferably water-soluble vinyl compounds with a hydroxyl group. According to the invention, however, it is preferred if the agent contains no hydroxyethyl methacrylate (HEMA) or HEMA ester. According to the invention, it is therefore possible to dispense with the use of this substance which has a high risk of allergy.
- An electron donor which is effective in an acidic environment is to be understood as any substance which, at pH values below 7, preferably also in the acidic range (pH 3 and less), can react with a polymerization initiator of an autopolymerizing material in such a way that the first , to
- Fillers in the sense of the invention can be organic or preferably inorganic fillers, for example quartz, (pyrogenic) silicic acid, aluminum oxides, glasses such as barium glasses, aluminum fluorosilicate glasses or the like. Suitable fillers are known to the person skilled in the art.
- the fillers or the filler contain a compound releasing Zn 2+ or Mg 2+ ions.
- Ion-releasing means that the fillers or filler constituents release Zn2 + and / or Mg 2+ ions under the conditions of the use of the kit in an aqueous environment or in the oral cavity.
- the dental restoration material can harden by two different reaction mechanisms. The primary curing takes place through the rapid free radical polymerization of the polymerizable compounds. Secondary curing takes place in the polymer matrix through a cement reaction between the zinc or magnesium ions on the one hand and excess phosphate groups of the primer on the other. This cement reaction has two benefits.
- the phosphoric acid esters and / or diphosphates of the primer of the kit according to the invention particularly preferably contain at least partially polymerizable double bonds.
- the primer particularly preferably contains:
- R 2 is H or
- the percentages in claim 2 relate to the so-called resin content of the primer, which is 100% for a solvent-free mixture. It decreases according to the amount of water added.
- the spacer group in the phosphoric acid derivatives is preferably selected from the group consisting of alkylene groups with 2-4 C atoms, ethyleneoxy or propyleneoxy groups, which can consist of up to 4 glycol units (ethylene or propylene glycol units), and alkylene groups with 2-4 C atoms which are substituted with one or two hydroxyl groups.
- Preferred spacers are ethylene or propylene groups, and also a group of the formula
- the reaction mixture is analyzed by 31 P-NMR spectroscopy. It has the following composition: 1% phosphoric acid, 39.5% phosphoric acid monoester, 29.1% phosphoric acid diester, 0.5% phosphoric acid triester, 28.5% diphosphate. All percentages are percentages by weight.
- a self-adhesive plastic film with a circular opening with a diameter of 5.5 mm was glued to each of the primed dentin surfaces to prevent the adhesive material from creeping up on the test stamp during the further process.
- the mixed polymerizable material from example 1 was then applied on the one hand as a thin film to the composite surfaces of the respective test stamps from example 2 and on the other hand a sufficient proportion (as a small drop) with the circular opening of the plastic film on the primed dentine surface of the exposed primer with scrubbing movements with a short-haired, solid brush for 5 s.
- the test stamp with its pretreated composite surface was then placed concentrically on the pretreated exposed area of the dentin surface under light pressure.
