Introduction: Dental implants have become an alternative to treat edentulism, however, some variants involving the implant itself and the receptor site can hinder treatment success. Dental implant failure is classified into late or early, depending on when it occurs. Objective: To determine the early success rate of implants installed during a specialization course in Implantodontics carried out between 2009 and 2012. Methods: The records of patients treated between 2009 and 2012 were analyzed. The following inclusion criteria were applied: P-I Brånemark Philosophy implants installed by means of the two-stage surgical technique, with implants submerged for a minimum period of three months. The selected patients underwent implant placement in the maxilla and mandible, subjected or not to bone graft. Evaluation was implemented at implant reopening. Implant survival after prosthetic loading was not considered. Results: The success rate was of 97%, with the presence or absence of bone graft, with implant positioning significantly influencing the final results. Conclusions: The success rate observed by this study not only corroborates the literature, but also reveals that the operator’s experience does not necessarily interferes in treatment outcomes. The findings also show that the posterior region had the highest number of failures, whereas bone graft sites had a higher success rate in comparison to other studies.
