Immediate implantation may result in wound dehiscence and bleeding or loosening of the implant. 1. Wound splitting and bleeding: If the suture is not properly done, the wound may split or bleed, and infection may be triggered when there is poor oral hygiene or acute inflammation. Do not suture the wound too tightly or too loosely, after the surgery, there is pressure, it may also cause bleeding. 2. Loosening of dental implants: the implant does not match the socket, or the biocompatibility between the implant and the alveolar bone is not good, which may also cause loosening of the implant. Immediate weight bearing after implantation, such as eating hard things will accelerate the resorption of the alveolar bone, which will also trigger the loosening of the implant. The hazards of immediate implantation are common in the above situations, the specific needs to be combined with their own situation, you can go to the dentist to consult.
