When the tooth has only residual root, if the residual root can expose at least 1.5mm of root height below the section, it is feasible to use staking crown restoration, if the residual root is not long enough, it can be extracted and then implant prosthesis or movable prosthesis restorative treatment, details are as follows.
1. Pile core crown restoration: the root has enough length, and at least 1.5mm of root surface height below the section can be exposed after crown extension or traction, the pile can be inserted into the root canal to obtain retention, and the crown can be used to restore the tooth defect.
2. Implant denture: If the length of the residual root is not enough to make a stump crown, after its extraction, the thickness and height of the alveolar bone in the missing teeth area meet the requirements of implant denture, and implant denture restoration is feasible.
3. Activity denture: If the alveolar bone in the missing teeth area does not meet the requirements of implant restoration, activity denture is feasible.
It is recommended to go to regular medical institutions to receive professional treatment.
