  • Patent number: 5418221
    Abstract: Binding between parts of living mineralized tissue such as between a tooth and the jaw bone is induced with a composition containing mammalian enamel matrix isolated from tooth germs and a carrier such as water, and optionally an adhesive containing fibrinogen, factor XIII and thrombin. The enamel matrix is a precursor to tooth enamel and induces binding by forming cementum tissue. The enamel matrix may be obtained from bovine or porcine species. The composition is particularly applicable in dental therapies including loosening of teeth due to periodontitis, transplantation of teeth or in reintroduction of teeth disconnected by accident. The composition may also be used for healing of artificial implants such as tooth implants and implants of skeletal replacements such as artificial hip joints. In the case of a dislocated tooth, the composition is applied to a surface of the tooth root and the tooth is put back into its alveolus and lightly fixed for some weeks.

  • Patent number: 5098891
    Abstract: A composition for use in inducing binding between parts of mineralized tissue by regeneration of mineralized tissue on at least one of the parts, containing as an active constituent a protein fraction originating from a precursor to dental enamel, so called enamel matrix;a process for inducing binding between parts of living mineralized tissue by regeneration of mineralized tissue on at least one of the parts using such composition.
