Artificial titanium alloy is plastic, and the domestic technology is very mature. My skull has been broken because of injury, and the edge will naturally wear out, and most of it is no longer suitable for skull. My family has repaired the titanium skull, and the cost is about 40,000 to 50,000. Remember to go to a big hospital, not a small one. There is little risk in the operation, so don't be too nervous. If you recover, you can make it up in three months instead of half a year. It is good for the patient's condition to make up early.
