In the rehabilitation of full arches with dental implants, more frequently in long-term edentulism, reduced bone volume might be present in the posterior regions of the mouth because of the pneumatization of maxillary sinus or for the superficialization of the inferior alveolar nerve. To face these limitations, a clinician has different therapeutic options, such as long distal cantilever, short implants, sinus lift, bone regeneration, or implants placed in specific anatomical areas such as the pterygoid region, the tuber, or the zygoma. Any of these procedures requires surgical and prosthetic expertise and has its own advantages, limits, risks, and complications, thus reducing patient’s acceptance.The aims of this study were to evaluate the clinical outcomes and patients’ satisfaction with immediately loaded full-arch fixed prostheses supported solely by axial or by a combination of axial and tilted implants in both jaws and to compare the outcome of tilted versus axial fixtures in the same patients up to 5 years.
