Introduction: This case describes the prosthetic treatment of a completely edentulous patient treated with the "Toronto Bridge" technique, an implant-supported (all-on-four/all-on-five) hybrid prosthesis. Objective: A 42-year-old male patient applied to our clinic for aesthetic and functional problems. After clinical and radiographic examination, the all-on-five treatment concept for the edentulous maxilla and an all-on-four treatment concept for the edentulous mandible were planned. In the maxilla, two distal implants were placed at an angle of 30-45°. Three straight implants were placed in the anterior region of the maxilla. In the mandible, two distal implants were positioned at the anterior to mental foramina at an angle of 30-45°. Two straight implants were placed in the anterior region of the mandible. The digital impressions were taken, and the frameworks and veneers were designed according to the "Toronto Bridge" protocol. The frameworks and veneers were fabricated by milling zirconium blocks and fixed. The occlusion was rechecked for any interferences. Results: This case report showed success and no complications for all-on-four/five treatment concept "Toronto Bridge" prostheses at the six-month follow-up. Conclusion: After the clinical and radiographic examination in the control appointment, it was observed that the patient was satisfied with the prosthesis, the patient's quality of life increased, and there was no problem in the care of the prosthesis.
