Implant placement in fresh sockets versus implant placement in healed bone:

This retrospective study assessed the success of immediate and non-immediate implants installed in patients undergoing planned extraction of all remaining teeth and rehabilitation with implant-supported full fixed prostheses.

Patients in need of dental implants for full fixed prostheses to replace teeth extracted in the maxilla and mandible were included in this study. Dental implants were installed in the same surgical procedure, immediately at the extraction site, or in healed bone.

Implant success, complications, and failures were recorded during follow-up. Forty-one patients with 512 implants were included in the study. Healing progressed uneventfully for 501 installed implants, but nine implants were lost in the non-immediate group and two were lost in the immediate group, during a mean follow-up of 44.9 months.

All failures in both groups were observed in the maxilla. The success rate was the same in both groups, at 97.8%. This retrospective analysis showed that with thorough patient evaluation, the extraction of all residual teeth and implant installation in a single surgical procedure is a safe and predictable treatment modality for the successful rehabilitation of the edentulous patient with a fixed prosthesis.
