Target price: The TM concept is explained in detail using scientifically sound findings and comprehensivelydocumented case studies. The individual work steps are realistically illustrated with videos, and sufficient implementation of this strategy can be achieved by means of a clinical course. Seminar content: The dento-alveolar volume is a structural-biological and functional unit. If teeth are lost, the essential stimulus of the dento-alveolar information flow is missing. The subsequent resorption processes lead to a considerable loss of periodontal and alveolar hard and soft tissue structures and have therapeutic consequences. Surgical/augmentation measures are sometimes very extensive and invasive as well as very stressful and costly for the patient. This problem has contributed to the development of the socket preservation philosophy. However, it has been shown that even with this approach, preservation of the socket is only possible to a limited extent. The approach of using replantations (root segments) to maintain the dentoalveolar information flow and regenerate tissue lost through extrusion represents a completely new approach. The goal of achieving biological regeneration means breaking new ground in dentistry. The periodontal ligament and the supraalveolar fiber apparatus are the key to this. Minimally invasive and without major adverse effects on the patient and in a shorter treatment time, clinical results are achieved that are at least on a par with those achieved using surgical techniques.
