OBJECTIVETo investigate the clinical feasibility and technical characteristics of immediate loading and to access the short-term clinical results of treatment.
METHODSThis study included 3 completely edentulous patients and 24 patients who were partially edentulous from March 1999 to December 2003. 21 implants were immediately loaded and provided support for mandibular overdenture for 3 fully edentulous patients. 30 implants were placed in 21 partially edentulous patients and implants were immediate loaded in edentulous mandibular providing support for fixed provisional prosthesis within 6 months. Then, metal-ceramic crowns were completed. All patients were followed up by 1, 3, 6, 12 months and the patients were checked every 12 months.
RESULTSA total of 42 implants were loaded immediately. From March 1999 to December 2003, no implants were lost during follow-up (range 3 to 49 months, mean of 28 months). No infections, nerve or sinus damage or other sequelae occurred. No implants exhibited peri-implant radiolucencies. Moreover, immediate loading seems to increase the ossification of the alveolar bone around endosseous implants. Patients were satisfied with the treatment.
CONCLUSIONSThe data and the experience described in this study indicate that immediate loading with restorations using appropriate surgical and restorative techniques can predicate the completely edentulous and partially edentulous mandible in some cases. Further study is needed to determine the long-term result of immediately loaded implants.

OBJECTIVEThe feasibility and clinical effects of hollow obturator prosthesis for the repair of maxillofacial defect immediately after maxillectomy for cancer were assessed.
METHODSThirteen patients with T3-4aN0M0 maxillary neoplasm were treated by the prostheses immediately after maxillectomy. According to the 3D-CT reconstruction of nasal sinus, the 3D stereoscopic prototype was constructed before the surgery. Simulating surgery with Surgicare 5.0 software and then the prosthesis 3D stereoscopic model was shaped. The prosthesis was made quickly and precisely with methacrylate resins according to the model and the print mold before surgery, with supplementary tooth at the bottom of prosthesis. In the surgery, the prosthesis was installed instantly after maxillectomy. The patients were followed up at 1, 3 and 6 month after the surgery, respectively. The facial features and the pronunciation clarity were examined and the questionnaires were carried out in the patients, with comparation by paired t-test. The hollow obturator prosthesis would be replaced by permanent prosthesis made of methacrylate resins at 6 month after the surgery.
RESULTSThe hollow obturator prostheses were installed accurately and maxillofacial defects were repaired immediately after maxillectomy in the 13 patients. Postoperative follow-up showed there were significant differences in eyeball sagging (t = 4.67, P < 0.05), mid-facial region collapse (t = 5.67, P < 0.05), and pronunciation clarity (t = 16.38, P < 0.05) between patients with and without prostheses. Questionnaires showed that all the patients were satisfied with the retention of prostheses, the improvement of appearance, the improvement of the symptom of water choking and speech definition. Six months after the surgery, the hollow obturator prostheses were replaced smoothly by permanent prostheses in 11 of the 13 patients.
CONCLUSIONThe precise and instant repair of maxillofacial defect by prosthesis after maxillectomy can improve survival quality of patient.
