All-on-4 / All-on-6 is a treatment we offer for fully edentulous patients. X is the number of implants in each jaw. Four implants are the minimum. Although the price of 4 implants sounds more attractive than that of more, sometimes at least six implants need to be placed in each jaw. There is no universal situation, so after an intraoral examination by our specialists and a CT scan, the patient will know the exact number of implants needed.
