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.

OBJECTIVETo investigate clinical feasibility and technical features of immediate loading with linear occlusion on 2-implant-supported overdenture and to evaluate short-term effect of the treatment

METHODSSix edentulous patients with severe residual ridge resorption were enrolled. Two interforaminal implants were inserted for each patient and then immediate impressions were taken. Implant-supported bar-retained overdentures were restored for the patients within 24 hours. Clinical and radiographic examinations were conducted post-operative 1 week and 1, 3, 6, and 12 months. Thereafter at every 6 months the stability of implants, tissue situations around implants, radiographs and satisfaction level of patients were examined for each patient.

RESULTSSix cases and 12 implants were followed from 9 to 30 months. No implant was loosened or dropped. Sulculus bleeding index was 0-1 and probing depth of sulcus was less than 2 mm. The gingival tissues around the implants were healthy. Radiographic examination showed that bone resorption was less than 1 mm in the first year. The alveolar bone around the implants hasn't show obvious resorption stable height. Patients were satisfied with the implants.

CONCLUSIONSThe results of this study indicate that immediate loading using linear occlusion on implant-supported bar-retained overdenture is predictable in some cases and can achieve satisfaction in the short-term service. Further study is needed to assess the long-term results.
