I believe many people will have questions about whether orthodontics can be done only half-mouthed. Due to the different degree of personal tooth deformity, many people have great doubts about whether orthodontics can correct only half of the mouth. There are very strict requirements for the degree of tooth deformity to do half-mouth correction. The alignment of upper and lower bite is very important, that is, the alignment of cusp and fossa, that is, the state that upper and lower teeth bite two at a time is necessary, and the cusp and fossa can bite together steadily, so that chewing food can exercise its normal function, chewing efficiency will be high, and digestive function will be smooth and smooth. From the standpoint of professional orthodontics, the practice of only half-mouth orthodontics is easy to make the occlusion of upper and lower teeth unable to align, which leads to the failure of orthodontics. For example, only the upper jaw, not the lower jaw, after the upper jaw is aligned, the dental arch has formed a relatively stable oval shape, but the lower jaw is still crowded and irregular, and the upper and lower occlusion is completely irregular, and the vertical and horizontal occlusion relationship may not be very good. This kind of functional occlusion can never bite well naturally. In this way, the alignment between teeth will be uncoordinated, the occlusal relationship will not be stable, and the occlusal function will not be very good in the future. Over time, it will lead to occlusal interference, which may cause pain in the mandibular joint and unstable tooth arrangement. After a long time, dentition will gradually relapse and become irregular again. As can be seen from the above introduction, generally do not do single jaw correction, unless it is really a very, very simple situation, just fine-tune the occlusion, otherwise, it will cause occlusion disorder, and it will be difficult to end up. In the future, it is bound to enter the whole mouth correction again, which is really not worth the candle. Some doctors indulge patients, which is unconscionable and irresponsible, and will eventually harm patients. Jinqin dental experts also remind everyone that when choosing a dental hospital for orthodontics, we must pay attention to carefully selecting a regular dental hospital.
