Dental implants are widely employed in modern dentistry for the rehabilitation of patients affected by edentulism, whether limited to a single missing tooth, multiple adjacent teeth, or involving complete dental arches. In particular, full-arch rehabilitations provide both functional and aesthetic restoration of completely edentulous arches or of severely compromised dentitions that the preservation of the remaining teeth is no longer clinically feasible. Among the various treatment strategies available, the Columbus Bridge Protocol™ represents an established implant-prosthetic approach for full-arch rehabilitation through the use of implant-supported prostheses with immediate functional loading. The non-surgical management of peri-implant diseases can be performed using a variety of tools, which are considered equivalent in effectiveness when used individually, according to the Guidelines for the Prevention and Treatment of Peri-implant Diseases. These include ultrasonic devices with implant-specific tips, titanium curettes, chitosan brushes, and air-polishing systems using glycine-based powders. These instruments effectively remove biofilm and deposits without compromising the implant surface, unlike stainless steel curettes, which can induce microscopic alterations. Such alterations may facilitate microbial colonization and complicate effective biofilm removal. In particular, for the removal of soft deposits, air-polishing devices with glycine powder have been shown to reduce clinical signs of inflammation in cases of peri-implant mucositis and may enhance the efficacy of non-surgical therapy in peri-implantitis. Furthermore, the use of fine-grain powders such as glycine does not cause surface alterations to the hard tissues of natural teeth or to titanium implant surfaces, nor does it lead to epithelial erosion of the soft tissues. In patients with full-arch implant-supported prostheses, air-polishing devices represent an effective method for professional oral hygiene, including the prosthetic-mucosal interface, without requiring prosthesis removal. Regarding home oral hygiene, the Guidelines for the Prevention and Treatment of Peri-implant Diseases do not provide universally applicable recommendations. Instead, they emphasize the importance of personalized instructions and motivation strategies, tailored to the individual needs of each patient. For patients rehabilitated with full-arch implant-supported prostheses, in addition to compliance, prosthetic design must ensure adequate cleanability. Ideally, designs should avoid the reconstruction of soft tissues, thereby facilitating daily hygiene procedures. The primary home-care tools recommended for these patients include manual or electric toothbrushes, sponge dental floss, and interdental brushes. The use of an angled toothbrush has also been suggested to improve access to difficult areas, such as prosthetic surfaces in direct contact with the mucosa and distal cantilevers.
