A method for improving soft tissue attachment which includes the steps of coating a surface of a material, to which surface soft tissue is to be attached, with a coating rich in TiOand/or SiO, and applying the coating where soft tissue attachment is desired. An implant in which a surface or surfaces of the implant intended to be attached to soft tissue are coated with a porous coating rich in TiOand/or SiO, and the use of a porous surface coating rich in TiO, SiO, or TiOand SiO, for the manufacture of an implant for soft tissue attachment are also disclosed.

Method for improvement of soft tissue attachment and implants making use of said method

The invention relates to a prepreg comprising a base part, said base part comprising fibers and a matrix, said matrix being at least partially uncured. The prepreg is characterized in that it further comprises a surface part consisting essentially of bioactive filler material, said bioactive filler material being in particle form and at least partially and at most partially embedded in said base part. The invention also relates to a composite obtainable by curing said prepreg. The invention further relates to a mineralizing sheet for treatment of hypersensitive teeth and to the use of said prepreg and composite.

Prepreg and its use

The invention relates to polymerizable multifunctional polymer composites and compositions, which are suitable for dental and medical applications, such as dental prostheses, filling materials, implants and the like. It also relates to a method for the manufacture of such polymerizable multifunctional polymer composites and compositions, and to the use of the multifunctional polymer composites and compositions in dental and medical applications. A multifunctional polymer composite or composition is manufactured from 30-99 wt % of a monomer mixture containing 30-99 wt % of a dendrimer or a combination of dendrimers and 1-70 wt % of a reactive solvent or a combination of reactive solvents, and 0.1-70 wt % of a nanofiller or a combination of nanofillers.

Dental and medical polymer composites and compositions

Controllably dissolvable silica-xerogels prepared via sol-gel process and their use. A delivery device including controllably dissolvable silica-xerogel into which structure a biologically active agent is incorporated. Pharmaceutical preparations including this device. Medical devices for orthopedic and surgical purposes which contain controllably dissolvable silica-xerogels, which may further include a biologically active agent.

Dissolvable oxides for biological applications

A prepreg containing fibers and a curable matrix, the prepreg having a core and a surface part encasing the core, where the matrix of the core and of the surface part are made of the same material and where the proportion of the matrix to the fibers is higher in the core than in the surface part. A composite obtainable from the prepreg as well as the use of the composite or prepreg are also disclosed.

Prepreg, a composite and their uses

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.

Compositions for controlled release of a biologically active agent, and the preparation thereof

A material for medical use in humans and/or animals bearing a biologically active agent, the material being multilayered, as well as a device of this material and a method to produce it. The material includes a core material, where the core material is formed into a body, optionally having the shape of a finished device; two or more layers of coating material of which the first layer has been applied onto the core material and additional layers have been applied onto the coating material of a preceding layer; and where at least one of the layers includes the biologically active agent. A feature of this invention is that the coating material is a biopolymer, a sol-gel produced silica gel or a biologically active molecule.

Multilayered material bearing a biologically active agent and the preparation thereof

A material suitable for the reconstruction of an individual's tissue, particularly supportive tissue such as bone tissue, insertable into the tissue. The material is characterized by being composed of wood heat-treated within the temperature range of 100-220&#xb0; C. in the presence of water vapor. The invention also relates the use of the wood.

Material suitable for an individual's tissue reconstruction

This invention relates to bioactive sol-gel derived silica fibers, methods for their preparation, an implantable device comprising the fibers and the use of the device for tissue guiding or bone repair.

Bioactive sol-gel derived silica fibers and methods for their preparation

Plastic based composite and its use

The invention relates to a method for reducing the viability of detrimental oral microorganisms in an individual, said method comprising subjecting the individual's oral cavity to a bioactive glass, the average particle size of which is less than 100 &mgr;m. Furthermore, this invention concerns a method for the prevention of dental caries and/or gingivitis in an individual, said caries being caused by a cariogenic bacteria; or for prevention or treatment of periapical infections. Further the invention relates to a method for the whitening and/or mechanical cleaning of an individual's teeth.

Method for reducing the viability of detrimental oral microorganisms in an individual, and for prevention and/or treatment of diseases caused by such microorganisms; and whitening and/or cleaning of an individual's teeth

A porous composite suitable for filling a recess or a through-passing hole in an implant. The composite includes particles A prepared from a bioactive material and particles B prepared from a non-bioactive material or weakly bioactive material, which is sintratable with the bioactive material, such that particles A and particles B have been sintered together to a porous composite. Particles A and particles B are essentially homogeneous in size. Also disclosed is an implant which contains a core and the composite.
