The increasing life expectancy of patients, and the desire for a more functional life alongside with the development of the technology in dentistry, as well as the development of the branch of implantology itself, has led to the fact that today patients at an older age want and can get very high-quality, long-lasting and especially functional dental-prosthetic works that make their everyday life easier. Until recently, the established therapy of total toothlessness was reduced to total dentures. With the propulsive and fast development of implant prosthetics, therapeutic solutions were obtained where total toothlessness can be repaired with fixed bridges, cemented or fixed with screws, or semi-fixed solutions in the form of total dentures worn and retained on the crossbar or with locators. The most common choices for the toothless jaw are 4 or 6 placed implants with the polygonal load. Among the most common and most accepted solutions in use are fixed works "All-on-4" and "All-on-6", and as mobile solutions there are already mentioned prosthesis with bars or with locators. Their choice and the best solution for the patient should be left to the therapist. Of course, you should listen to the wishes of the patient, and explain everything to him in detail - both negative and positive sides of the recommended dental work and therapy plan. It all depends on the financial capabilities of a patient. The paper presents all four versions of the rehabilitation of toothless jaws, their advantages and disadvantages; there are functional comparisons and the duration of the work in the mouth. The contribution of the work is the facilitation and better understanding of some prosthetic solutions during the treatment of total edentulism with implants.
