Implantable medicine delivery systems, devices, and associated methods are disclosed herein. In one embodiment, a method of enhancing bone regeneration in a human or animal body includes implanting a three-dimensional scaffold in the human or animal body. The three-dimensional scaffold is constructed from a porous ceramic material, a ceramic-polymer composite of a biodegradable ceramic material and a polymer, or a ceramic-polymer-metal composite of a biodegradable ceramic material, a polymer, and a metal and embedded with curcumin in the porous ceramic material, the curcumin at least partially coating an exterior surface of the porous ceramic material. The method also includes directly and controllably releasing the embedded curcumin into a circulatory system of the human or animal body according to a release profile, thereby achieving enhanced bone regeneration in the human or animal body.
