Aggressive periodontitis is a multi-factor disease with early onset and rapid progression. The treatment of extensive aggressive periodontitis is relatively more complicated and requires close cooperation between multiple disciplines. Its long-term efficacy is worth looking forward to. Orthodontic treatment after basic periodontal treatment to control periodontal inflammation is not only beneficial to the control and maintenance of periodontal disease, but also can improve the facial appearance and chewing function of patients^[1]。 The traction effect of orthodontic force also provides the possibility for alveolar bone restoration and regeneration^[2], restoration and reconstruction of pathological periodontal tissue under the effect of orthodontic force is a clinical proposition of interest to both periodontist and orthodontist. A case of severe extensive aggressive periodontitis was treated in the Department of Periodontology of the Second Affiliated Hospital of Zhejiang University School of Medicine, and good results were achieved after perfect periodontal-orthodontic combined treatment. Follow-up was performed for 7 years after the end of orthodontics, and the results were stable and reported below.

intraosseous lipoma (IL) is a benign primary tumor, with a prevalence of less than 0.1% of primary bone tumors. It can occur in all parts of the body, and it is more common in long tubular bone, mostly single, and there are multiple reports^[1]。 IL occurring in the mandible is rare. One case of mandibular IL was treated in the Department of Oral and Maxillofacial Surgery of Nanjing Stomatological Hospital, Affiliated Stomatological Hospital of Nanjing University School of Medicine. The report is as follows.

Meningiomas are composed of meningeal skin cells, that is, arachnoid cells. Most of them occur in the cranium, orbit and spine, and they occur in the ventricle or outside the dura mater. Extracranial meningiomas account for only 2% of all meningiomas. Meningiomas originating in the mandible very rare^[1,2,3]。 A case of primary mandibular meningioma was admitted to Wuxi Second Hospital affiliated to Nanjing Medical University, and there was no recurrence and metastasis after treatment. The report is as follows.
