From June 2003 to June 2007, 18 patients with mandible tumor and cyst were selected from Affiliated Hospital of Beihua University and Affiliated Hospital of Yanbian University, including 5 cases of malignant tumor and 13 cases of benign tumor. Lesion bone tissues were resected and appropriate reconstructed titanium plate was implanted and fixed by screws. The facial appearance and oral cavity function of patients were evaluated using radiographic imaging and classification standards. In addition, patient satisfactory content was investigated. Eighteen cases were followed up for at least 12 months, The titanium plate and mandible healed well and mandibular continuity was restored successfully during the follow-up period. All cases after operation showed good maxillofacial region appearance. Shape and degree of gape was well. Twelve cases had normal occluding relation and well masticatory function. However, 6 cases were unsatisfied. One case underwent another implantation due to titanium plate breakage. No tumor or cyst recurrence was found. Sixteen patients （89%） satisfied to the operation.
