Does bone grafting improve outcomes in coronectomy surgery? Long-term (5-9 years) clinical and radiographic follow-up of 78 adult patients
Abstract Purpose To report the long-term outcomes of 78 adult patients who underwent coronectomy with bone graft (CWG) of the bony crypt. Patients and Methods 78 patients with follow-up of at least 5-9 years underwent CWG. Preoperative imaging and probing depths were recorded, as were yearly follow-...

Summary: | Abstract Purpose To report the long-term outcomes of 78 adult patients who underwent coronectomy with bone graft (CWG) of the bony crypt. Patients and Methods 78 patients with follow-up of at least 5-9 years underwent CWG. Preoperative imaging and probing depths were recorded, as were yearly follow-up radiographs or CBCT and yearly post-op probing depths. Results Periodontal probing depths and bone levels on the distal surfaces of adjacent mandibular molars showed marked improvement compared to preoperative probing depths and bone levels. All retained roots maintained their immediate postoperative positions with no migrations and no re-operations required. Conclusion CWG is a predictable procedure that should be considered for patients at risk for developing sensory disturbances or for those with deeper (>4mm) preoperative probing depths on the distal surfaces of the adjacent molars. Adding bone graft appears to aid in preventing root migration and reducing probing depths on the distal of adjacent molars. |
