Abstract Background Calvarial bone grafts have been one of the grafting options that provides predictable results for three‐dimensional reconstruction severely atrophied ridges owing to their low resorption and rapid revascularization, thus providing adequate volume implant insertion. The aim this study was introduce a computer‐guided technique calvarial graft harvest minimize complications known with from donor site. Materials Methods Eight patients, suffering atrophied, completely edentulous maxillary ridges, an age range (21‐30 years) were operated on (six males two females). A custom‐made guide each patient based preoperative computed tomography (CT) fabricated harvesting outer table cortical blocks parietal bone, then particulate collected auto‐chip maker. Bilateral sinus lifting indicated in all cases. fixed intraorally particulates filled gaps created by lifting, whole complex covered collagen membranes titanium tacks. Immediate 6 months CT requested evaluation accuracy integration, respectively. Results In cases, found accurately fit into its preplanned position correctly locate anticipated site needed dimensions blocks. No intraoperative encountered such as breakage through inner or cerebrospinal fluid leakage. Postoperatively, cases showed uneventual healing except case had anterior dehiscence. Conclusion is safe atrophic maxilla.
