All-on-4 implant supported restoration has indication for patients with terminal dentition and edentulism patients (patient with no teeth). All-on-4 is noninvasive, low cost, full arch, and fixed dental implant bridges. The implant bridges for each jaw are usually supported by four to six dental implants which are fabricated from materials such as acrylic fused to titanium or monolithic zirconia. With this treatment we must often replace bone and soft tissue volume.
Patient can get immediate function (fixed provisional bridge) if the patient meets the criteria for immediate loading of implants. Bone grafting and Sinus grafting is avoided by tilting the posterior implants and utilizing the available bone. Overall, the All-on-4 method is a cost efficient solution that provides patients with a fixed full arch prosthesis on the day of the surgery.
