The article describes three clinical cases of implant-prosthetic treatment of patients who were admitted in order to replace missing teeth. Due to the location of deficiencies in the aesthetic zone, the method of choice was restoration with the use of dental implants and permanent dentures, and the results obtained were compared on the basis of the solutions used during treatment. In every case, when the implant-prosthetic rehabilitation process was completed, therapeutic, functional and aesthetic success was achieved, satisfying both the doctor and the patient. The adaptation to prosthetic restorations proceeded without complications. The use of hybrid zirconium abutments, particularly in the anterior region of arches, achieves aesthetically pleasing results. In order for zirconium dioxide implant prosthetics to succeed, it is essential that the strategic planning and design of the restoration by the dentist is completemented by the detail-oriented fabrication of the prostheses by the dental laboratory technician. Safety protocols must always be implemented in order to secure such rehabilitation of missing dentition.
