Surgically-guided zygomatic and pterygoid implants— a no-grafting rehabilitation approach in severe atrophic maxilla—A case report

No immediate loading was performed. Four months after surgery, the implants were loaded, and an excellent aesthetic and functional result was achieved with no increase in bone volume from bone grafts. The entire residual bone was used as an anchorage for the implants. The excellent results achieved demonstrate that zygomatic implants in association with other conservative and guided surgical approaches are a valid alternative to bone grafting in treating severe atrophic and edentulous maxillae. Conclusion In this case report, the accurately planned surgery made the use of local anaesthesia with intravenous sedation possible.
