The placement of implants in a tilted position may provide a viable treatment modality, especially for patients with atrophic maxillae. The treatment steps and procedures for a maxillary implant-supported removable dental prosthesis, as well as a mandibular telescopic crown-retained removable dental prosthesis, are described. The concept of tilted implants via 3D planning and flapless surgery is presented. The final outcome facilitated improvement in the patient's satisfaction and comfort, as well as long-term stability of the implants and prosthesis. In addition, there was a reduction in cost by avoiding augmentation procedures. Schlagwörter: flapless, guided surgery, maxillary dental prosthesis, tilted implants
