Hello, there are many dental implant doctors in Shanghai. For example, Tongji and Jiuyuan have many good doctors. Regular hospitals have it. The steps of tooth implantation are as follows: firstly, the dental nerve block anesthesia or submucosal local infiltration anesthesia is performed in the implant area. After successful anesthesia, the gingiva and periosteum in the operation area were cut with a scalpel to expose the bone surface, and the implant site was located with a positioning drill, and then the hole was prepared step by step with an implant drill. When the required implant diameter is reached, the implant is implanted into the alveolar bone, and finally the incision is closed. Three months later, after the implant was closely combined with alveolar bone, the crown was connected above the implant.
