Patients will experience facial swelling after dental implants, and this swelling is similar in principle to the swelling that occurs after tooth extraction. The human maxillofacial blood supply is rich and there is a rich arteriovenous network. Traumatic treatment can cause a local inflammatory response, and the richer the blood supply, the more pronounced the inflammatory response, so it is theoretically possible that swelling will occur after surgery. For us it is necessary to differentiate between implant cases. Some simple single-tooth implants have a low probability of swelling after surgery, because the operation is minimally invasive, even without flaps, and the implant is placed directly into the implant, which is almost non-invasive to the patient and the postoperative reaction can be minimized. However, for some implant surgeries, if the amount of bone is not enough and bone grafting is needed to expand the space, the post-operative reaction will be heavier because a large amount of material needs to be put in for bone grafting and the mucosa needs to be treated when the wound is closed, so it will lead to an increase in post-operative inflammatory reaction, and in this case, it is necessary to give the patient some anti-inflammatory and anti-swelling medication. In addition, the patient needs to rest as much as possible after the complex implant surgery, on the one hand, and speak less on the other hand, because some patients feel good about themselves after the dental implant, but swell up after two days, because the oral and maxillofacial movements will accelerate the blood circulation, which will aggravate the inflammatory reaction, so it is necessary to follow the doctor’s advice, carefully implement the treatment measures, rest more and speak less, and the swelling after the dental implant surgery can be effectively controlled.
