A medical implant comprising in components from a toothand stem cells harvested from at least one tooth. Tooth stem cells may beharvested from the dental pulp of mammalian teeth, such as uneruptedthird molars in humans. After the stem cells are removed and isolated fromthe other teeth tissue, the hard tooth may be ground into a base materialfor the manufacture of a porous matrix into which the tooth stem cells canbe added. Additionally, soft tissue from the harvested tooth may be used asa carrier scaffold for soft tissue applications such as meniscal or cartilagerepair.
