[Observation of clinical effect of vertically fractured molar teeth treated with elastic ligation].
OBJECTIVE
To evaluate the clinical effect of vertically fractured posterior teeth treated with elastic ligation.


METHODS
Eighty-six vertically fractured posterior teeth were chosen to be treated with elastic ligation for external fixation before root canal therapy (RCT), and then full crown prostheses were made for rehabilitation.


RESULTS
The success rate after 1 year, 2 years and 3 years were 97.67%, 93.02% and 88.37%, respectively.


CONCLUSIONS
Elastic ligation for vertically fractured posterior tooth before RCT can effectively prevent tooth fracture during treatment and preserve the tooth for functional use.
