Therapeutic effect of surgical extraction for the treatment of complicated crown and root fracture of anterior teeth

Abstract

Objective To evaluate the clinical effect of the surgical extraction of traumatized permanent teeth with complicated crown⁃root fractures. Methods Among the dental trauma patients diagnosed in the Emergency Depart⁃ ment of Beijing Stomatological Hospital, Capital Medical University, from January 2011 to January 2016, a total of 17 permanent teeth with complicated crown⁃root fractures were included in this retrospective study. According to the Inter⁃ national Association of Dental Traumatology guidelines, the roots were surgically extruded to a more coronal position and stabilized with splints to reconstruct the biologic width. The follow⁃up period was 6 months to 7 years. Results All 17 teeth with complicated crown⁃root fractures survived during follow⁃up. The most common complications were surface resorption (5 teeth), marginal bone loss (2 teeth) and tooth mobility (1 tooth). No periapical lesion or root resorption was found in surgically extruded teeth. Conclusion Surgical extraction is a safe and rapid treatment option in the manage⁃ ment of complicated crown⁃root fractures in permanent anterior teeth.
