Abstract
Disclosed is a material for filling bone defects having a three-dimensional steric structure. This material is produced by dissolving or suspending a substance in a solvent to give a solution or slurry, the substance containing a biodegradable resin as a principal component and bearing a siloxane; adding water to the solution or slurry to give a spinning solution, the water having a relative dielectric constant larger than that of the biodegradable resin; subjecting the spinning solution to electrospinning while applying a positive charge to a collector by a voltage supply and grounding a nozzle of a syringe without applying a charge thereto; thereby yielding the material on the collector.
