Improved compositions comprising a mixture of particulate bone growth material and polymeric carrier are provided. The particulate is preferably porous, resorbable, anorganic bone material. The polymeric carrier can be light-cured to form a cross-linked, biodegradable hydrogel. In one version, the bone growth material is a synthetic peptide bound to anorganic bone matrix particles and the carrier is methacrylated sodium hyaluronate (MHy) or methacrylated hydroxyethylcellulose (MHEC). The composition is particularly suitable for repairing defective dental and orthopedic bone tissue. The particulate and hydrogel carrier are biodegradable so the composition can be replaced by new bone formation over time.
L'invention concerne des compositions améliorées comprenant un mélange de matériau de croissance osseuse particulaire et un support polymère. Le matériau particulaire est de préférence un matériau osseux inorganique poreux résorbable. Le support polymère peut être photopolymérisé afin de former un hydrogel biodégradable réticulé. Dans un mode de réalisation, le matériau de croissance osseuse est un peptide synthétique lié à des particules de matrice osseuse inorganique et le support est du hyaluronate de sodium méthacrylé (MHy) ou de l'hydroxyéthylcellulose méthacrylée (MHEC). La composition convient notamment pour réparer des défauts du tissu osseux dentaire et orthopédique. Le matériau particulaire et le support en hydrogel sont biodégradables afin que la composition puisse être remplacée par de l'os néoformé au fil du temps.
