    • Composites and methods of producing a mouldable bone substitute are described. A scaffold for bone growth comprises nanocrystalline hydroxyapatite (HA), a bioresorbable plasticizer, and a biodegradable polymer. Plasticizers of the invention include oleic acid, tocopherol, eugenol, 1,2,3-triacetoxypropane, monoolein, and octyl-beta-D-glucopyranoside. Polymers of the invention include poly(caprolactone), poly(D,L-Lactic acid), and poly(glycolide-co lactide). Methods of regulating porosity, hardening speed, and shapeability are also described. Composites and methods are described using nanocrystalline HA produced with and without amino acids. The scaffold for bone growth described herein displays increased strength and shapeability.

    • The invention provides methods and systems that control the application of a material onto micro-rough implant surfaces. Thus, the present invention provides method of applying crystalline nanoparticles onto the surface of an implant to produce an implant with a crystalline nanoparticle layer on its surface, the method comprising: providing an implant substrate body; applying crystalline nanoparticles onto the surface of the implant; and rotating the implant, to produce an implant with a crystalline nanoparticle layer on its surface. This method of nanoparticle application is designed to promote the integration of implants, such as dental and orthopedic screws, into living tissue, and offers the ability to control the thickness and uniformity of the nanoparticle layer, in one or several layers, while simultaneously retaining the microroughness of the implant. Further provided are systems for applying crystalline nanoparticles onto the surface of an implant and implants having a crystalline nanoparticle layer on their surfaces.
    • 本发明提供了控制材料在微粗植入物表面上的应用的方法和系统。 因此,本发明提供了将结晶纳米颗粒施加到植入物的表面上以在其表面上产生具有结晶纳米颗粒层的植入物的方法,所述方法包括:提供植入物基底体; 将结晶纳米颗粒施加到植入物的表面上; 并旋转植入物,以在其表面上产生具有结晶纳米颗粒层的植入物。 这种纳米颗粒应用方法旨在促进植入物(如牙科和矫形螺钉)与活组织的整合,并提供一个或多个层面控制纳米颗粒层的厚度和均匀性的能力,同时保留 植入物的微粗糙度。 还提供了将结晶纳米颗粒施加到植入物的表面上的系统和在其表面上具有结晶纳米颗粒层的植入物。
