Post-extractive implants (i.e. PEIs) are widely used to reduce surgical steps and improve patient compliance. The aim of this study is to perform a retrospective study on 2,273 PEIs to evaluate their survival rate. In the period between January 2008 and December 2013, 877 patients (498 females and 379 males) were operated at the BDD private Practice Clinic (Milan, Italy). The mean post-surgical follow-up was 30±17 months (max min, 84 1). Two thousand two hundred and seventy-three PEIs (EDIERRE Implant System SpA, Genoa, Italy) were evaluated in the present study. All patients underwent the same surgical protocol and agreed to participate in a post-operative check-up program. SPSS program was used for statistical analysis. Survival rate (SVR) was 97.7% since only 53 fixtures were lost from a total of 2,273 implants. Cross-tabulation between failures and timing of loading demonstrated a statistically significant higher risk of failures in case of immediate loading (p= 0.013). There were 26 failures out of 761 immediate loaded implants against 27 lost fixtures out of 1,485 delayed loaded implants. PEIs is a reliable procedure, however surgeons should carefully select those cases which can be immediately loaded.

Abstract
Post-extractive implants (i.e. PEIs) are widely used to reduce surgical steps and improve patient compliance. The aim of this study is to perform a retrospective study on 2,273 PEIs to evaluate their survival rate. In the period between January 2008 and December 2013, 877 patients (498 females and 379 males) were operated at the BDD private Practice Clinic (Milan, Italy). The mean post-surgical follow-up was 30±17 months (max min, 84 1). Two thousand two hundred and seventy-three PEIs (EDIERRE Implant System SpA, Genoa, Italy) were evaluated in the present study. All patients underwent the same surgical protocol and agreed to participate in a post-operative check-up program. SPSS program was used for statistical analysis. Survival rate (SVR) was 97.7% since only 53 fixtures were lost from a total of 2,273 implants. Cross-tabulation between failures and timing of loading demonstrated a statistically significant higher risk of failures in case of immediate loading (p= 0.013). There were 26 failures out of 761 immediate loaded implants against 27 lost fixtures out of 1,485 delayed loaded implants. PEIs is a reliable procedure, however surgeons should carefully select those cases which can be immediately loaded.
