Advancements in CAD-CAM technology have allowed for a variety of options in implant-supported fixed prosthesis restorations for completely edentulous patients. For patients with severe alveolar bone resorption, zirconia prosthetic restorations that include the gingival portion, such as implant-supported hybrid dentures, are possible, as well as monolithic zirconia prosthetic restorations in the form of crowns. The integration of digital technology in fixed prosthetic restoration using implants enables predictable treatment through diagnosis and virtual surgery by integrating the patient's clinical and radiological information. In this case, the utilization of digital software allowed for the establishment of implants in appropriate positions, considering both the remaining alveolar bone and the final prosthesis. By designing both the maxillary removable prosthesis and the mandibular fixed prosthesis simultaneously in CAD software, bilateral balanced occlusion could be easily achieved. Furthermore, maintaining the initial interocclusal relationship from provisional restorations to final prostheses allowed for convenient transition while ensuring functional and aesthetic satisfaction.

In the case of fully edentulous patients with severe alveolar bone resorption, the consideration of ‘All-on-X’ implant-supported fixed prosthesis after placing four or more implants in the anterior maxilla is possible. Recent advancements in digital dentistry have enabled systematic and predictable treatment in all phases, including diagnosis, surgery, and prosthesis fabrication. By incorporating digital dentistry techniques such as digital complete denture, implant surgical guides, facial scanning into the conventional restoration process, it is possible to reduce the complexity of the prosthesis fabrication and effectively achieve the transition from provisional prosthesis to definitive prosthesis in terms of both aesthetics and function.

For a full-mouth fixed prosthetic treatment of the edentulous patient, it is essential to confirm the proper tooth position and thorough evaluation of the remaining alveolar bone and soft tissue before surgery. CAD-CAM dentistry and guided implant surgery have such advantages of providing simultaneous planning of surgery and prosthetic treatment to ensure pre-knowledge of the treatment. In this clinical case, using the digital technology, digital temporary denture fabrication, esthetic evaluation before fixed prostheses treatment, and guided surgery planning was possible. After the surgery, previously obtained data was used for fabricating fixed temporary prostheses. Definitive zirconia prostheses transferred from the provisional prostheses were fabricated and functionally and esthetically satisfying results were obtained. [ABSTRACT FROM AUTHOR]

For successful restoration of maxillary anterior implants, both pink esthetics and white esthetics must be satisfied. For pink esthetic part, the role of appropriate provisional prosthesis restoration is important, and for white esthetic part, the color and shape of the definitive prosthesis is important. Multilayer zirconia can be used for natural tooth appearance due to the higher transparency of the incisal area compared to the conventional monolithic zirconia. Therefore, in this case, white esthetic part was achieved through multilayer zirconia after recovering function and esthetics through appropriate provisional prosthesis in a patient who lost the maxillary anterior teeth.

The most important factor in the treatment of fully edentulous patients using implants is the shape of the definitive prosthesis. After the shape of the definitive prosthesis is determined, residual bone analysis and selection of the implant type, number and position should be followed. In this case, for restoration of an edentulous patient fully implanted (except the maxillary right lateral incisor) without considering definitive prosthesis, facial esthetics and possibility of fixed type prosthesis were evaluated using complete denture. It was determined that the fixed type prosthesis was possible. Implants that could not be used for the definitive prosthesis were excluded from the treatment plan and fixed type provisional restorations were fabricated. After four months of provisional restorations, the patient showed stable occlusion and esthetic satisfaction. Definitive prosthesis was made of zirconia using CAD/CAM (computer aided design and computer aided manufacturing). The results were satisfactory during the 3 months of follow-up period after termination of treatment. [ABSTRACT FROM AUTHOR]
