The objective of this retrospective study was to evaluate the overall success of immediately loaded implants in the mandible. This report focuses on immediately loaded anterior and posterior mandibular implants.
Materials and Methods

A total of 979 patients received 2,904 mandibular dental implants placed from January 2007 to December 2008. One hundred sixty-one of the implants were placed anterior to the mental foramen, and 95 were placed posterior to the mental foramen. All immediately loaded implants were torque tested to 35 N-cm. All were provisionally restored the day of insertion.
Results

A total of 256 immediately loaded mandibular dental implants were placed in a 2-year period. Of the 256 immediately loaded implants, 252 integrated and were restored and 4 failed. Of the 4 failed implants, 3 were in the anterior mandible and the fourth was in the posterior mandible. All 4 were replaced, integrated, and have been restored. The survival rate for immediately loaded implants in the anterior mandible was 99.4%, and the survival rate in the posterior mandible was 97%.
Conclusion

Immediately loaded implants have predictable clinical success in the anterior and posterior mandible.
