It was reported that a patient experienced a dental implant loss.Region 13 bone level was low and it was decided to perform sinus lift.During this operation it was noticed that the bone structure was much narrower than what was expected after cbct.The sinus lift was performed via lateral access without problems.As there was enough bone to stabilize the implant, the implant drilling was carried out immediately.The drilling itself had no problems, but the drill was guided too palatally, close to perforating the bone wall.When placing the implant, it felt as if it slipped palatally.Due to no primary stability, the implant was taken out in the same session.To widen the bone ridge, volumax was placed palatally and implant will be placed after 4-6 months.
