Precautions after implantation are as follows:1. Do not eat food that is too hard or too sticky for 24-48 hours after surgery to avoid loosening of the blood clot and dislodging, which is detrimental to the healing of the trauma. 2. Do not chew food with the affected side to prevent squeezing the trauma and causing displacement of bone powder and periosteum. 3. Do not engage in strenuous exercise for one week after surgery to avoid accelerated blood circulation, which may lead to continuous bleeding of the trauma. 4. If the trauma is large, apply cephalosporin and nitroimidazole antibiotics, and add appropriate amount of dexamethasone to reduce swelling if necessary. 5.When the trauma is large, remove the sutures in 7-14 days to prevent the trauma from splitting.
