[Why not try to move on ankylosed tooth orthodontically?].

Due to presence of rigid inorganic matrix, mechanical perturbations cannot affect the bone blood supply or deform osteocytes. Because convincing evidence that bone can directly perceive mechanical forces in lacking, we hypothesize that mechanical perturbations can only elicit remodeling by acting through a soft tissue envelope. These soft tissue envelopes are the periodontal ligament, periosteum, fibrous tissues that can form around implants, sutures and the like. Fibroblast, preosteoblast, and mesenchymal cells are composing the envelopes. It is possible that these cells are indeed responsible for bone remodeling subsequent to forces application.
