The invention relates to a medical dental implant with the surface biomimetic function and a manufacturing method thereof. The medical dental implant is characterized in that the medical dental implant comprises an implant body and further comprises an outer layer of a bionic artificial bone structure, the outer layer is integrally combined with the outer surface of the implant body and capable of simulating the alveolar cavity bone tissue structure around the tooth root portion of a missing tooth of a patient. According to the medical dental implant and the manufacturing method thereof, the outer layer of the bionic bone structure, which is formed in a 3D printing mode and of a massive structure, serves as the outer layer of the tooth implant body, and therefore an ideal embodiment used for simulating the artificial bone surface structure is provided. More importantly, a good activity surface layer structure foundation beneficial to bone marrow stem cell and bone-formation related cell adhesion, proliferation and growth and capable of playing the final bone-formation function is provided, the surface of the foundation is loaded with chemical components such as calcium and phosphate and bioactive molecules such as collagens, hence, a bone-formation promotion microenvironment is created, bone cell generation is induced, and fast and firm bone combination can be achieved at the early stage.
