The present application relates to a medical light diffusion implant and, more specifically, to a functional implant to emit medical lights so as to induce rapid recovery after an implantation. According to the present invention, A medical light diffusion implant, comprising a socket including a space therein, capable of being fixed to a living body and a crown coupled with the socket so as to seal the socket, wherein the socket is transmittable by lights, and comprises a light source unit included at an inner space of the socket and the crown coupled to each other, to emit the lights.
