A method is described for inducing the formation of cementum and a periodontal ligament between a dental implant and bone by administering cementum attachment protein (CAP) together with a calcineurin inhibitor such as cyclosporin A (CSA). Also contemplated is an implant kit comprising a titanium or other biologically inert dental or orthopedic implant and a coating of CAP and a calcineurin inhibitor such as CSA. Furthermore, application of CAP and CSA to dental root surfaces can be used to induce the regeneration of a periodontal ligament during treatment for periodontal disease. A similar method for reattaching a fibrous structure, such as a tendon, ligament or joint capsule, to bone is described.
