[Sinus lift with autogenous bone graft: surgical technique].

Insufficient maxillar bone crest does not allow dental implant placement. The sinus lift technique with an autogenous bone graft compensates this deficiency. This technique is performed in two steps: iliac autogenous bone harvesting and sinus graft. After describing the possible complications, the various approaches of this technique are presented. This pre-implant surgery must be performed by experienced surgeons.
