![]() ![]() At the end of the intervention, a postoperative orthopantomographic radiograph ( Fig. The night after the intervention, the patient was administered intravenous antibiotics and an antiphlogistic agent. To facilitate the required tension-free closure, releasing incisions helped extend the full-thickness mucoperiosteal soft tissue flaps to fully cover the grafts ( Fig. ![]() Once all the blocks were fixed, any sharp edges were rounded to even out the graft surfaces ( Fig. Intraorally, the blocks were fixated to the maxillary alveolus with osteosynthesis screws (Osteomed LP, Addison, Tex) with a diameter of 1.6 mm and occasionally of 1.2 mm ( Figs. To get the best congruence between the grafts and recipient sites, the bone blocks were first shaped on the stereolithographic model and on the patient’s jaw ( Figs. CC18.21).īased on the grafting plan developed using the stereolithographic model, the iliac bone blocks were trimmed and contoured to sculpt a J shape. For the sinus graft we used a 50% mixture of cancellous iliac bone and xenogenic bone ( Fig. On the left side, based on the three-dimensional study of the model and the development of the graft guide, involvement of the alveolar antral artery was carefully avoided ( Fig. Simultaneously, on the maxillary bone, bilaterally, two sinus graft procedures were accomplished using the sinus graft guides to transfer to the patient the preoperative plan designed and executed on the stereolithographic model ( Fig. ![]() A bone block, whose dimensions were determined by the harvest guide, was harvested from the right iliac crest ( Figs. The first intervention was for the maxillary reconstructive surgery, which was performed under general anesthesia.Two different surgical teams operated simultaneously, one on the iliac site and the other on the maxillary site. The patient also sought to limit the length of time for each surgical procedure and the postoperative course by fractionating or staging the interventions. The patient had claustrophobic syndrome and a very accentuated pharyngeal reflex therefore she preferred to undergo general anesthesia for all the treatment, and, when possible, under conscious sedation.
