Impact of Orthodontic Treatment on Crestal Bone Resorption in Periodontally Compromised Patients: a Case Series

摘要

Objective: Since the number of patients with periodontitis undergoing the orthodontic treatment (OT) is increasing and no report specifically focuses on the impact of OT on crestal bone remodeling (CBR), we performed a retrospective study. Materials and Methods: Twenty six patients had OT on 445 over 645 teeth. The mean tooth high inserted into alveolar bone was 0.47% before OT. X-rays and χ2 test were used to evaluate differences in CBR. Results: No tooth was lost. We have demonstrated that (1) OT has no adverse effect on bone supporting the treated teeth (since the mean crestal bone resorption was 0.03 mm and 0.26 mm in treated and untreated teeth, respectively) (2) treated and untreated teeth have no statistical difference in CBR, and (3) the length of active OT is not a critical factor on CBR. Conclusion: OT of periodontally compromised patients can achieve good results on CBR.
