Hello, complications of oral plastic surgery: 1, wound dehiscence, infection: suture is too tight or too loose, especially in the case of inducing infection, which is more likely to lead to local wound dehiscence. Timely debridement and suture to avoid implant exposure. Infection is mostly caused by contamination of operating area or instruments and other complications. 2. Hemorrhage: mucoperiosteal peeling or extensive submucosal peeling is harmful, especially postoperative compression, which is prone to submucosal or subcutaneous bleeding. For example, submental congestion will also occur when the implant passes through the lower edge of the mandible in the first-stage operation.
