摘要:
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.
摘要:
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° C. in the presence of water vapor. The invention also relates the use of the wood.

摘要:
An implant for replacing a tooth or another part of bony tissue comprises a first non-resorbable layer (2) containing a bioglass, e.g., CaP-glass; a second layer (4) of a mixture of bioglass and hydroxyl apatite resorbable into bone or biomass, and a slowly resorbable intermediate layer (3) containing bioglass and being disposed between said first and second layers; the inclusion of said hydroxyl apatite into the second layer (4) securing the stability of bonding of the implant to the tissue. When strength is required, the implant further comprises a metal core (1) to which the first layer (2) is attached. The materials may also be used as a granule filler in bone cavities and as a block for the replacement of bone.
摘要:
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.

The invention relates to a matrix band that is characterized in that it comprises fibers and a matrix, at least a portion of said matrix being at least partially uncured. The invention further relates to a dental restoration kit, a prepreg and the use of said matrix.
摘要:
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.
