Injectable composite material for bone repair, and preparation method thereof

An injectable composite material for bone repair comprises a biological tissue material and bioceramics in order to serve as a three-dimensional scaffold for bone regeneration. The biological tissue material consists of microfibers having a naturally cross-linked structure without additional physical or chemical cross-linking, has superior biological compatibility, and can be slowly and completely degraded in vivo. The bioceramics in the composite material serves as a reinforcing phase. When combining the biological tissue material with the bioceramics, the composite material provides a template for bone tissue regeneration to effectively induce bone growth. The injectable composite material for bone repair can be used to fill bone defects, particularly critical-sized bone defects, and can be combined with a biological agent such as bone marrow to improve its biological activity. Therefore, the composite material can be widely used to repair bone defects caused by trauma, tumor resection, osteonecrosis, and infection.

Implant comprising a calcium salt-containing composite powder having microstructured particles

Implant comprising composite powder with microstructured particles, obtained by a process in which large particles are bonded to small particles, wherein the large particles have a mean particle diameter in the range from 10 μm to 10 mm, the large particles comprise at least one polymer, the small particles are arranged on the surface of the large particles and/or are non-homogeneously spread within the large particles, the small particles comprise a calcium salt, the small particles have a mean particle size in the range from 0.01 μm to 1.0 mm,
wherein the particles of the composite powder have a mean particle size d50 in the range from 10 μm to less than 200 μm and the fine fraction of the composite powder is less than 50 vol %. Therefore, the subject matter of the invention further are implants obtained by selective laser sintering of a composition comprising a composite powder, especially as an implant for applications in the field of neuro, oral, maxillary, facial, ear, nose and throat surgery as well as of hand, foot, thorax, costal and shoulder surgery.

PERSONALIZED MEDICAL DEVICE AND METHOD OF ITS PREPARATION

A personalized medical device intended for correction of defects, in particular in the orofacial area is multicomposite and comprises a hard tissue replacement and a soft tissue replacement. The hard tissue replacement is a hard core of biocompatible thermoplastic material and the soft tissue replacement is a biocompatible elastic substance. Preparation of personalized medical device even in the prenatal period using CT, MRI and 3D/4D electronic USG imaging and “additive manufacturing” technology.
