Problems solved by technology

However, currently used bone filling materials have insufficient cell adhesion and proliferation, and it takes a long time for alveolar bone regeneration
In addition, the adhesiveness to the alveolar bone and the indwelling ability to the affected area cannot be said to be good, and even if it is embedded with GBR membrane, it may leak from the affected area.
[0006] In addition, there are also cases where bone cement is used, but there is a disadvantage that cells cannot infiltrate into the bone cement
[0007] As mentioned above, currently used bone regeneration materials have problems of insufficient cell adhesion and proliferation

Embodiment

[0118] Hereinafter, the present invention will be specifically explained, but the present invention is not limited to the following examples. It should be noted that textbooks in the technical field (for example, Molecular Cloning: A Laboratory Manual (3 Vol. Set): Cold Spring Harbor Laboratory Press) can be appropriately referred to during the experiment.

[0119] Non-woven fabric manufacturing 1

[0120] To 7 g of polylactic acid (Mitsui Chemicals, LACEA, H-400) was added 43 g of a mixed solution of hexafluoroisopropanol: methylene chloride = 8: 2 (mass ratio) and dissolved to obtain a polylactic acid solution (14w / w %). The polylactic acid solution was filled in a syringe (Henke SASS WOLF, 5 ml), a needle (Terumo, Non-bevel needle 21G1.1 / 2) was installed in the syringe, and then set in an electrospinning device. The distance between the syringe and the ground electrode serving as the target was set to 8 cm, and the spraying amount and spraying time were changed under the cond...

Abstract

An object of the present invention is to provide a bone regeneration material suitable for bone (in particular, alveolar bone) regeneration. The present invention provides a non-woven fabric containing a bone prosthetic material wherein the bone prosthetic material is included between biocompatible fibers that constitute the non-woven fabric. The non-woven fabric may be suitably used as a bone regeneration material (in particular, a dental bone regeneration material).

Description

[0001] This application is a divisional application of the application date of February 28, 2012, the application number is 201280010881.4, and the invention title is "non-woven fabric containing bone filling material". Technical field [0002] The present invention relates to a non-woven fabric containing a bone filling material. Background technique [0003] In recent years, in the case of tooth defects caused by aging or periodontal disease, the treatment of implanting artificial tooth roots in alveolar bone, installing artificial tooth crowns and superstructures on it (the so-called "implant treatment" "). [0004] If the tooth is defective (that is, if it causes tooth loss), the alveolar bone supporting the tooth is quickly absorbed and reduced. Therefore, for implant treatment, the thickness of the alveolar bone is often insufficient when the artificial tooth root is embedded in the alveolar bone. If the thickness of the alveolar bone is insufficient, even if the artificial ...
