When the upper and lower rows of posterior molars are missing or the buccal occlusion of the posterior teeth is not correct, the posterior teeth of the maxillary molars will grow downward beyond other upper rows of teeth. Without corrective evaluation and treatment, sometimes it is necessary to shorten teeth or cut bones to make dentures, but it also makes the "project" huge. But now there is a new way to deal with the excessive eruption of maxillary teeth, which can be called "little nails can do a lot". Dr. Koro Renbang, from the Department of Stomatology and Orthopaedics of Chengda Hospital, pointed out that the excessive eruption of maxillary molars is often caused by the malocclusion of mandibular posterior teeth. Generally speaking, it can be divided into two categories. The first category is mandibular molar loss. For example, the mandibular first molar germinates at the age of six, and it is very likely that it will be pulled out due to tooth decay, and the maxillary molar will gradually grow and germinate for a long time. The second is the buccal malocclusion of upper and lower molars, which is also a special malocclusion caused by the eruption position of upper and lower teeth during tooth replacement. You may need to grind your teeth. In terms of treatment, the first type of maxillary molar eruption caused by long-term loss of mandibular molar will make denture and dental implantation difficult. In the face of excessive eruption of maxillary molars, if there is no corrective treatment, the excessive eruption of teeth may be polished to make room for mandibular dentures. There are also some surgical operations that remove the alveolar bone of the maxilla and reposition it to obtain enough space. The second malocclusion, in which the teeth are inclined to the left and right, is an abnormal occlusion, which is often manifested as excessive eruption of the maxillary posterior teeth and occlusion on the buccal side of the mandibular posterior teeth. In order to correct the internal and external relationship between buccal side and lingual side, the traditional orthodontic treatment and correction process tend to make the malocclusion protrude and cause the occlusal plane to tilt left and right, which may not be an ideal choice from aesthetics. Using bone nails as molars depends on the strength of the surrounding teeth. It is very difficult to repress the overblown maxillary molars, because the maxillary molars are big and strong, and sometimes not only 1 molars have overblown problems; At present, bone nail can be used as a good anchor nail for maxillary molar pressing, which is convenient for making denture in edentulous area of mandibular molar and rebuilding its normal occlusal function. Pay attention to oral hygiene to avoid inflammation and infection. The main advantages of bone nail correction are that it is more comfortable than headgear, and it increases the correction efficiency. When it is implanted, it needs only local anesthesia, and there are almost no exposed wounds. After correction, it can be taken out. However, attention should be paid to oral hygiene and cleaning around bone nails to avoid inflammation and infection. Regular dental examination for half a year, timely intervention and treatment. However, Dr. Luo Renbang said that the best solution is actually "prevention". From an early age, I have developed the habit of regularly checking my teeth for half a year, finding malocclusion and tooth decay of molars as early as possible, and intervening and treating them in time. Adult patients with missing teeth should also be treated as soon as possible, so as not to affect the teeth around the missing teeth and the bitten teeth, which will lead to the need for additional correction in future dentures.
