Reorganization of periodontium tissue after orthodontic appliance is a essential for succesful therapy in orthodontics. The mean amount of relapse was about 40 % of the tooth movement produced before. Cellular changes allow orthodontic tooth movement as a respons even if tooth movement stop. This study has aim to explain cellular changes in orthodontic tooth movement and potensial role of periodontium to the orthodontic relapsing. In vitro experiment during orthodontic tooth movement on fibroblast in tension area flattened inducing synthetic events and its change with removal orthodontic appliance. Collagen fibres were partially reorganized and rearranged during orthodontic movement and continue after movements stops which supracrestal fibers remodel extremely slowly. When active force is removed but passive stress of the periodontal ligament remains through retention of the tooth in its new position, resorption would continue as long as necrotic tissue is still present.
