Document Type and Number:

Japanese Patent JP2005521440

Kind Code:

A

Abstract:

Bioresorbable osteoconductive compositions and methods of using the composition as a scaffold for bone repair in periodontal, alveolar or maxillary regeneration, bony cranial defects, and spinal regeneration are disclosed. The bioresorbable compositions contain a bioresorbable polymer, a micro or nano particulate filler and a pore creating substance. The bioresorbable polymer can be electronically unsaturated and cross-linkable with a cross-linking agent. The micro or nano filler can be any natural biocompatible material such as a metals, calcium carbonate, carbon, a biocompatible synthetic material, or a bioceramics such as hydroxyapatite. The pore creating substance can be an effervescent agent such as a carbonate and an acid.
