Immediate implantation refers to the process of placing an artificial implant in a fresh extraction socket immediately while the tooth is extracted. The difference between immediate dental implants and ordinary dental implants is as follows: 1. Ordinary dental implants are placed in the alveolar bone after 3-6 months of healing, and then implants are placed in the alveolar bone. Immediate dental implants are implanted and restored on the same day of tooth extraction, and patients do not have missing teeth to meet their requirements for aesthetics and chewing function. It takes 3-6 months from the extraction to the final restoration. 2. Immediate implants are placed on the same day of extraction, and the GBR technique is used to support the alveolar bone and reduce the resorption of the alveolar bone in the extraction area. In the process of healing, the alveolar bone will inevitably resorb. Therefore, immediate implantation is more conducive to preserving the alveolar bone compared to ordinary implantation. 3. Ordinary implantation is performed on the fully healed alveolar bone, which is relatively less risky, while immediate implantation is more sensitive and requires certain skills by experienced doctors to complete it well. Immediate implantation can be done under the guidance of a digital guide, and the implant site and direction can reach a more ideal position.
