Statement of the Problem: Rehabilitation of edentulous maxilla with severe bone resorption in the posterior area represents a clinical challenge especially in the placement of implants. The "All-on-4" concept removed the need for complex surgical interventions such as sinus elevation and bone grafting. This study aimed to evaluate the clinical and radiographic outcomes of the "All-on-4" concept in fully edentulous maxilla by using R2GATE software planning for flapless computer-guided surgery and immediate loading. Methodology & Theoretical Orientation: A prospective study was conducted between April 2019 and April 2021. Ten fully edentulous maxilla adult patients aged between 35 and 60 years. All patients were treated in the oral and maxillofacial department at Damascus University. The flapless computer-guided surgical procedure according to the "All-on-4" concept was performed under local anesthesia. All implants were immediately loaded with screw-retained provisional acrylic resin prosthesis on the same day of surgery, and the final prosthesis was delivered 4 months after surgery. All the clinical and radiographic outcomes were evaluated for all patients at 4 and 12 months post-operatively. Findings: The overall implant survival rate was 95%. The mean marginal bone level was 0.35 and 0.66 mm after 4 and 12 months of follow up respectively. Mechanical complications were most common (Fixed provisional prosthesis fracture and abutment, prosthesis screw loosening). Conclusion & Significance: The "All-on-4" concept for rehabilitation of edentulous maxilla with the placement of immediate fixed prosthesis by using flapless computer-guided surgery could be an effective and predictable treatment with a high survival rate. This technique offers less discomfort and mechanical complications after surgery.
