Application of metallic guides and reverse scanning for full‐mouth rehabilitation using implant‐supported prostheses: A case report

Advances in dental implantology, such as immediate loading protocols, digital planning, and improved biomaterials, have revolutionized the treatment of edentulous patients by offering faster and more predictable outcomes. This case report describes a complete digital workflow for maxillary and mandibular implant‐supported full‐arch prostheses in an edentulous patient with nonuniform bone shape, limited interarch space, and excessive gingival display. A full‐arch immediate loading protocol, including a fixation base, a scalloped bone‐reduction guide for preserving the interdental bone, an osteotomy guide, and provisional prostheses, was digitally designed and fabricated. The reverse scan technique using laboratory analog was used for fabricating definitive zirconia prostheses. The reverse scan technique integrates digital technology with clinical practice to improve the accuracy of full‐arch implant restorations.
