Survival evaluation of surgical extrusion for the management of complicated crown‐root fractured maxillary incisors: A clinical study

Abstract

AbstractThis study aimed to clinically evaluate the survivability of surgically extruded teeth, to assess the success rate and predictable factors pertaining to alterations in both hard and soft tissues adjacent to extruded teeth. A total of 46 complicated crown‐root fractured maxillary central and lateral incisors with >75% tooth structure loss relatively due to trauma were included. Preoperative clinical and radiographic variables were recorded. Single operator performed endodontic treatment before surgical extrusion. Patients were recalled for review at 6, 12, 18, 24 and 36 months. Survivability was assessed using Kaplan–Meier survival analysis. With a mean follow‐up of 2.8 years, survival rate was 95.7%. Mobility observed in only two cases. The crown‐root ratio was favourable (1:2) in all the cases except for five teeth. Only two teeth displayed non‐progressive root resorption. Survival of surgically extruded teeth relies on significant predictors like favourability of CRR and implementation of atraumatic extrusion.
