Abstract: The present invention relates to a kit for dental restoration, comprising an aqueous activation agent solution comprising polyacrylic acid having a molecular weight of 100000-1000000 g/mol, wherein the concentration of the polyacrylic acid in the solution is 1-30 mg/l; and a lining material comprising 20-80 wt-% of a dental resin and 20-wt-% of an ion releasing material, which ion releasing material comprises at least one of calcium, phosphate and zinc, based on the total weight of the lining material.

Abstract: The present invention relates to a dental material comprising a thermoset methacrylate-based polymer resin and cellulose nanocrystals, wherein the cellulose nanocrystals have been modified to be hydrophobic.

Abstract: The invention relates to a dental material comprising a polymer resin, particulate fillers and randomly oriented inorganic fibres, wherein an average largest dimension of the particulate fillers is 0.3-1.2 ?m, the inorganic fibres have a diameter of 4-8 micrometre and an aspect ratio of 20-80 based on an average length of the inorganic fibres and the dental material is void of other fibres. Additionally, the total amount of particulate fillers and inorganic fibres is 70-85 wt-% of the total weight of the material, and the amount of inorganic fibres is 20-35 wt-% of the total amount of particulate fillers and inorganic fibres.

Abstract: A dental composition comprising 10-50 wt-% of a methacrylate-based first matrix component, a polymerisation system and as a second matrix component 1-50 wt-% of a compound having a general formula (I).

Abstract: The present invention relates to a dental material comprising a thermoset methacrylate-based polymer resin and cellulose nanocrystals, wherein the cellulose nanocrystals have been modified to be hydrophobic.

Abstract: A biodegradable carrier is produced for preservation and/or controlled delivery of biologically active agents where said biodegradable carrier is a silica xerogel which is made from water and silane by using acid or base as a catalyst, and biologically active agents in said biodegradable carrier are infecting and/or transfecting viruses. Silica xerogel material can be pharmaceutically acceptable and it can be used as a medicine.

Abstract: A composition for controlled release of a biologically active agent from a carrier. The biologically active agent is heparin or a related biologically active acidic polysaccharide and the carrier is a sol-gel derived silica xerogel. The xerogel is derived from a tetraalkoxysilane such as tetrethoxysilane (TEOS) and part of the tetraalkoxysilane is replaced by an organomodified alkoxysilane, preferably an akylsubsitituted alkoxysilane. The invention also includes a method for the preparation of this composition.
