Immediately loaded implants placed with simultaneous sinus lift procedure and cross-arch rehabilitation. A case report after five years

The immediate loading treatment concept in implant dentistry seems to be successful in cases of cross-arch stabilization. This report presents the restoration of an edentulous maxilla using an immediately loaded prosthesis supported by six implants with a progressive thread design placed in poor bone qualities. Specifically, two of these implants were inserted simultaneously after a sinus lift elevation and augmentation of the sinus cavity using autogenous bone grafting material. A cross-arch stabilization using a provisional bridge provided immobilization of the implants until healing. The final restoration was delivered 4 months after loading. The case report presents clinical and radiographic evaluation of the immediately loaded implants with an excellent result 5 years after loading.
