Introduction: Implant placement and positioning in severely resorbed maxilla and mandible is often difficult. For this reason, it has been suggested that distal implants should be tilted to rule out graft application and provide a more predictable implant protocol in severely resorbed ridges in edentulous jaws. With this technique called All-on-four, implants can be used in the long term without decreasing the chance of success and the prosthesis can be loaded immediately.
Case Presentation: A 53-year-old male patient applied to our clinic for implant-supported prosthetic rehabilitation due to his edentulous areas. As a result of the clinical and radiological examination, it was decided to extract all the teeth and to rehabilitate with the all-on-four concept. Anterior implants were performed according to the standard implant drilling protocol. Posterior implants were placed with a maximum tilting of 450 distally, avoiding the maxillary sinus in the maxilla and the mental nerve in the mandible. Implants
were placed with a minimum torque of 35 N. Multi-unit abutments were torqued with 35 N. Metal hygienic caps were placed on the multiunits. Temporary and fixed immediate prostheses were applied to the patient on the 1st post-operative day.
Result: All-on-4 is a method of treatment with accepted applicability and safety. With a total of 4 implants, 2 of which are tilted and 2 of which are straight, without further surgical procedures, prosthetic rehabilitation can be easily applied both in the immediate and in the late period.
