All-on-4 (or 6) at the Time of Extraction--Success Rates

The Journal of the American Dental Association reports a two-year retrospective analysis of upper four or six implants placed immediately after tooth extraction and immediately used to support a fixed bridge.  Between 2001 and 2009, in 65 patients (32 women, 33 men), aged 43-83 years (average 60.5), 334 dental implants were placed in postextraction sockets and supported teeth immediately. The follow-up period was two years.  97.9% of the implants survived after two years and 100% of the prostheses were stable. These survival rates were comparable with that reported for traditional delayed implants in the upper jaw.  JADA 2/2012
