Restoration of the posterior maxilla with reduced bone height and pneumatized sinus is a challenge to the implant surgeon. The surgeon has the option of a direct sinus-lift approach or an in-direct blind approach. Both of which have its own complications. Displacement of an implant into the maxillary sinus is rare occurrence and normally seen after the implant has been in service for a number of months. The displacement of an implant at the time of surgery is even rarer. This report presents a case of an implant displaced into the maxillary sinus during first stage surgery and discusses its possible cause, management and follow-up.
