Traumatic fracture of anterior teeth is not uncommon in clinical practice, and the principles of treatment vary according to the size, location, and symptoms of the injury. The selection process is as follows: (1) First, the damage to the tooth and gingival periodontal tissue is examined, dental films of the injured tooth are taken, and the root and alveolar bone are observed, which is crucial for subsequent treatment. (2) If the defect is limited to the enamel or the crown defect is small and the nerve is not exposed and there is no sensitivity, restoration of the tooth shape is sufficient for aesthetic restoration. (3) If the dentin is exposed and the pulp is mildly sensitive, desensitization treatment can be done first. If the sensitivity is more severe, desensitization + pulp capping, and then composite resin aesthetic restoration crown form. (4) If the pulp is exposed, pulp extraction and root canal treatment are feasible for adult permanent teeth; for young permanent teeth, live pulpotomy is performed, and resin veneer or porcelain crown aesthetic restoration is performed at the same time when the root development is completed. (5) If all the teeth are broken, pile crown restoration can be done after root canal treatment; if the root tip is not yet formed, apical induction can be done to preserve the tooth papilla at the root tip to facilitate the continued development of the root tip. Key points: 1, as far as possible to protect the dental nerve and retain the dental tissue; 2, whether the resin veneer effect is satisfactory, in addition to the choice of methods and materials, the doctor’s aesthetic concept, medical ethics and professional technology is particularly important.
