The aim of this 5-year evaluation was to assess the clinical characteristics, management, and prognosis of postsurgical periimplant infection during the initial bone healing period.


Nine hundred twenty-five implants (514 patients) placed without bone augmentation procedures were assessed. Ten implants (1.08%) in 7 patients (1.36%) were diagnosed as postsurgical periimplant infection. Different management methods were adopted respectively.


All reported implant infections were diagnosed after 2 weeks from implant surgery. Among the infected cases, 7 implants (70%) in 4 patients (57%) were successfully treated and loaded. Three implants (30%) in 3 patients (43%) failed to achieve osseointegration.


It is suggested that surgeons should observe the patient closely to detect possible infection during at least 1 month from surgery. Most postsurgical periimplant infections could recover and achieve osseointegration after timely and effective management.
