A medical implant comprising in combination a synthetic, biological, or autologous matrix (or scaffold) and pluripotent stem cells derived from human teeth. Stem cells are harvested from the dental pulp of extracted wisdom teeth. After the stem cells are removed, the hard tooth is ground into a base material for the manufacture of a porous matrix bone into which the stem cells can be added. Additionally, soft tissue from the harvested tooth may be used as a carrier scaffold for soft tissue applications such as meniscal or cartilage repair.
