Reconstruction of severely atrophic edentulous maxilla with implants placed in autogenous iliac bone graft: a modified approach

摘要

This clinical report describes a case of maxillary dental rehabilitation using five implants placed simultaneously in three cortico-cancellous iliac bone blocks and rigidly fixed to the residual bone with titanium mini-screws 2-mm in diameter and mini-plates. All a€?empty spacesa€? between the bone segments were filled with iliac bone chips harvested from the diploe of iliac bone mixed by Bio-oss. The second surgery was performed 5 months later, when all five implants were integrated, and one cover screw was exposed to oral cavity. Two months after the second surgery, abutments were connected to the implants and loaded with a fixed partial denture.
