① Tooth extraction/non-tooth extraction: Some people have sparse teeth, so they don't need tooth extraction during orthodontics/orthodontics, and there is no cost for this part. However, patients who need tooth extraction may have to pay hundreds of extra tooth extraction fees according to the number of teeth extracted.
② Different correction methods: The common clinical correction methods include traditional metal correction, ceramic semi-invisible correction, metal self-locking correction and full invisible correction. The low cost is about six or seven thousand, and the high cost may be about thirty or forty thousand. Different choices correspond to different aesthetics and comfort.
③ Dentistry in different hospitals: Many people think that the prices of dentition in hospitals in the same area are similar. In fact, this is an incorrect cognition, because even hospitals in the same area will still lead to a gap of thousands of dollars due to different charging standards and business concepts.
