Document Type and Number:
WIPO Patent Application WO/2017/115906
Kind Code:
A1
Abstract:
The present invention relates to: a drug releasing dental biodegradable fiber chip in which biodegradable fibers, which have an average diameter of 0.01-100 μm, are entwined in a network shape and compressed so as to form a fiber chip having a width of 0.5-50 mm, a height of 0.5-50 mm and a thickness of 0.05-5 mm, and pores are distributed between the biodegradable fibers entwined in the network shape, wherein the biodegradable fiber comprises, as constituent components, a biodegradable natural polymer, a drug and a cross-linking agent; and a manufacturing method therefor. According to the present invention, the biodegradable fibers form a network (net) structure so as to be easily insertable into or attachable to a wound site, and even if mixing with a body fluid occurs, flowing does not occur at the attached position, so as to be effectively applicable only at a healing site. In addition, the biodegradable fiber itself contains a drug as a constituent component, thereby enabling the contained drug to be continuously released for a predetermined period, can be used for disinfection, antibiotics and the like, has excellent biostability, has no side effects even after insertion into an animal or human body, and enables a drug to be eluted for a long time.
