APICOECTOMY TREATMENT OF AN IMPACTED MAXILLARY CANINE THAT RESISTED ORTHODONTICALLY FORCED ERUPTION
Figure 2 . Panoramic radiograph and a CBCT reconstruction show the apical bend in the canine , which anchored it to the cortical bone of the nasal cavity floor . The canine could not descend to eruption , despite sufficient space and orthodontically-induced forces
Figure 3 . One week after apicoectomy of the apical bend , and after endodontic treatment
evidence of lesion or resorption was observed , and a third ( last ) follow-up appointment was scheduled ( Fig . 4 ). At the last follow-up , 26 months postoperatively , a complete clinical and radiographic examination was performed . It included a panoramic radiograph and a CBCT scan , with lateral and cross-sectional reconstructions . The patient was symptom-free , and the right maxillary canine had maintained its functional position . There were no radiographic signs of periapical lesion or root resorption . The lamina dura was visible and the periodontal ligament space was normal . The radiographic examination showed a reduction of the alveolar bone height around the canine ; this reduction was attributed to generalized periodontitis ( Fig . 5 ).
