[Reimplantation and autotransplantation of teeth. Review of the literature].

The most important factor for a favorable long-time prognosis of replanted and autotransplanted teeth is a short extra-alveolar periode. Implanted teeth should be followed radiographically with special attention to external resorptions as these correspond well with the histological picture. Avulsed teeth replanted within 30 minutes have a fairly good long-time prognosis. A little less than half of the teeth are still in place after five years. In international replantation the procedure can be performed with a short extraalveolar periode. By using the methods giving the shortest extraalveolar periods during autotransplantation a favorable long-time prognosis is to be expected in most of the cases. Implantation can be performed with all teeth at any developmental stage. However, a favorable long-time prognosis can only be expected where the teeth are removed from their alveoli without severe damage to the periodontal membrane. Compared to the altenative treatments which often are removable or fixed appliances or artificial implants, the prognosis for implanted teeth is sufficient good to accept the treatment as lege artis.
