All-on-Four is a revolutionary concept providing patients with fully functioning teeth on dental implants in a single procedure. This technology was developed by Nobel Biocare and utilizes collaboration between both the restorative doctor and the implant surgeon. This merging of knowledge and experience achieves not only increased safety, but also a more precise implant placement. In addition, the fabrication of a final prosthesis is completed prior to the surgery. The computer-guided implant surgery facilitates minimally invasive surgery–this benefits the patient in that there is less postoperative discomfort, less swelling, and less bruising. Patients can often resume their normal activities the next day.
The process begins when a CAT scan is taken of the patient’s jawbone. This CAT scan allows for the generation of a three-dimensional model of the jawbone that can then be used with virtual reality software to plan the implant placement without the presence of the patient. The results are a more accurate implant placement and less chair time for the patient.
