How long after a tooth extraction is suitable for dental implants? This is probably one of the most frequently asked questions on the Internet. The answer to this question is not very simple, because there are huge individual differences between people, and the treatment options for different tooth positions are different, so I would like to divide it into the following cases, which may be easier to understand: 1. The professional term is early implantation; 3, implantation more than 12 weeks after tooth extraction, the professional term is delayed implantation. Second, the posterior region (commonly known as: big teeth, slot teeth): 1, about 3 months after the regular extraction of teeth for implantation. 2, individual cases due to serious tooth infection, alveolar bone resorption and destruction, healing for more than 4 months before implantation. 3. In a few cases where multiple posterior teeth are extracted consecutively, implantation can be considered at the same time of tooth extraction. As for each specific case, it is necessary to go to the hospital for examination and film, and the doctor will choose according to the examination results, his own experience and technical level.
