A 73-year-old woman in Miaoli recently suffered a single front tooth fracture due to a fall. She is afraid that her front teeth must be pulled out. But according to the doctor's assessment, the patient's subgingival incisor fracture can be treated by "tooth replantation". After half a year's treatment and observation, the damaged incisors were successfully preserved and the tooth appearance was restored.

For silver-haired people, if they accidentally crack their teeth, it will be a headache to think of tooth extraction and tooth implantation. Chen, a physician at the dental comprehensive treatment center of Miaoli Daqian Hospital, said that if the front tooth is fractured due to an accident, when the buccal fracture line is more than 3mm below the gum, it is generally recommended to remove it and then repair it with a bridge or dental implant; However, because the patient has oblique fissure, if the lingual height is enough, the tooth can be pulled out and rotated 180 degrees, replanted and fixed 1 month, followed by observation for 3-6 months, and then restored with a single denture.

Dr. Chen said that whether to keep the original tooth will be evaluated according to the position of the broken tooth, the amount of bone under the gum, the situation on the other side of the broken tooth, and whether the root has preservation value.

Dr. Chen said that the patient's front teeth were obliquely cut and broken under the gums. Six months after tooth replantation (left), the periodontal ligament returned to normal, and then a single denture was used to restore the beauty of the teeth.

The course of treatment is about half a year, and patients need patience; For older patients, it is necessary to consider whether the tissue regeneration function is sufficient. For this lady, it is estimated that the success rate of replantation can reach 80%, and finally the teeth are successfully preserved and the damage is reduced.
