The present study was undertaken to determine the feasibility of using primary stability as a predictor of implant success the short-term clinical result of treatment. Methods: This study included 32 patients, in whom a total of 80 implants were placed, 34 in maxillary sites and 46 in mandibular sites. Who were partially edentulous. From May 2001 to June 2004. All implants were immediately loaded in partially edentulous patients. Then, Within 2 hours providing support for fixed provisional prosthesis and noble-metal-ceremic crowns were completed with in 3 months. All patients were followed up by 1.3.6.12 months and after the patients were checked every 6 months. Results: There were no surgical complications. A total of 80 implants were loaded immediately, From May 2001 to June 2004, No implants were lost during follow-up (range 5-36 months, mean of 19 months), no infections, nerve or sinus damages or other accidents 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. Discussion: Clinical research has shown that immediate loading is a viable treatment modality. The favorable success rate reported in this study for rough-surfaced implants suggests that adherence to a protocol, an important parameter of which is primary stability above 32 cm, can lead to osseointegration. Conclusion: The results of this limited investigation suggest that patients who are partially edentulous may be immediately restorations, Provided that the dental implants are adequetely stable immediately after their surgical placement. The experience described in this study indicate that immediate loading with restorations using appropriate surgical and restorative techniques with one-stage JIAD(KOM) implant system can predicate the partially edentulous mandible in some cases. Further study is needed to determine the long-term result of immediately loaded implants.
