Disturbances in forming of the hard tissue of teeth and bones can be a cause of their malformation and translocation. The impact of permanent teeth is one of them. It can occur with translocation of the tooth germ. The aim of the study was to present an atypical translocation of impacted permanent teeth in children.
3.5 year clinical observation was carried out in 14 children (5 girls and 9 boys), aged between 9 and 12 years old. Patients were referred to our Department by orthodontists, paedodontists and General Dental Practitioners, due to impacted permanent teeth. According to the interview, in 8 cases children suffered from a trauma of a facial part of the skull, caused by a fall. On admitance patients were generally healthy. Basing on the clinical and radiological examination, translocation of the impacted permanent teeth has been diagnosed. In 9 cases it concerned medial maxillary incisors, whereas in remaining children--maxillary premolars. The extraction of such teeth has been performed as a part of the one day surgery procedures.
In the cases where basing on the radiogram, the position of the tooth allows to predict the latter translocation, the germ has to be extracted.
牙齿和骨骼硬组织形成过程中的紊乱可能是其畸形和移位的原因之一。恒牙的影响就是其中之一。它可能伴随着牙胚的移位而发生。本研究的目的是呈现儿童中受影响恒牙的非典型移位情况。
对14名年龄在9至12岁之间的儿童（5名女孩和9名男孩）进行了3.5年的临床观察。患者因恒牙阻生由正畸医生、儿童牙医和普通牙科医生转诊至我们科室。根据访谈，8例儿童因摔倒导致面部颅骨外伤。入院时患者一般健康。基于临床和放射学检查，诊断出阻生恒牙移位。9例涉及上颌中切牙，其余儿童涉及上颌前磨牙。此类牙齿的拔除作为一日手术程序的一部分进行。
在根据X光片牙齿位置可预测其后续移位的情况下，必须拔除牙胚。
