Oral and maxillofacial fractures mainly include maxillary fractures, mandibular fractures, zygomatic bone and zygomatic arch fractures, which are significantly on the rise due to the current massive increase in motor vehicles. The current treatment is that if the fracture is not significantly displaced a conservative treatment can be used. If there has been significant displacement and the bite of the tooth is misaligned then surgical incision and fixation must be chosen. During the surgical procedure, the fracture is repositioned and then a miniature metal titanium plate is placed to fix the fractured end. After the fracture heals, the titanium plate can be left in the body, but if the patient feels uncomfortable with the metal plate or if the plate is rejected or for psychological reasons, the titanium plate can be removed again surgically for internal fixation. In recent years, due to the development of polymer materials, there is an absorbable bone plate, which is implanted in the body and fixed at the fracture line to play a fixed role, so that the fracture heals, while it itself is automatically degraded within 12 to 18 months, without any toxic side effects on the human body. The absorbable bone plate can stabilize the fracture segment so that the fracture can heal normally, the occlusal relationship is well restored, there is no obvious foreign body reaction, no pain and discomfort, and it is a better fixation material.
