Definitions
- the invention relates to polymerizable, crosslinkable compositions containing polyalkylbenzene derivatives and / or derivatives of ring-shaped polycarboxylic acids and / or their anhydrides and their use, in particular in the dental field.
- Such compositions adhere to various, but especially to biological substrates.
- Compounds of this type can be used or added for general purposes, but especially in the dental field, as components for polymerizable adhesion promoters, adhesive filling materials, adhesive cements, sealers and for similar mixtures.
- Polymerizable mixtures based on monomeric compounds provided with one or more unsaturated groups form the basis for a large number of plastics, with compounds having acrylate and methacrylate groups being important in the dental and medical field.
- a stronger connection can therefore only be achieved over retention-rich areas, i.e. via a composite of a purely mechanical type, e.g. after etching the surface of biological or inorganic materials.
- adhesion promoters i.e. This deficiency can, however, be remedied by substrates which can react chemically with biological or inorganic material and also carry a polymerizable group.
- adhesion promoters are known, e.g. the organosilanes carrying vinyl or methacrylic groups.
- their adhesive properties are limited to silicon dioxide, glasses containing silicon dioxide, and ceramics and metal oxides, or base metals forming them. They show no adhesion on biological substrates and especially on tooth or bone substrates, but rather have a separating effect.
- a number of polymerizable adhesion promoters with other adhesion groups have been found for substrates of this type. There are those that react with the collagen or collagen-like portions of these substrates, e.g.
- Polymerizable carboxylic acids and reactive carboxylic acid derivatives are also known which show adhesion to the tooth structure, such as:
