Use of Glycine Powder and an Angled Implant Brush in Oral Hygiene Procedures in Patients Rehabilitated With Columbus Bridge Protocol

Professional removal of hard and soft deposits using titanium curettes, spongy interdental floss, and air-polishing with glycine powder. The glycine powder used had a particle size of 25 μm and was applied using a supragingival nozzle positioned 3 mm from the prosthetic restoration, with particular attention given to the areas in direct contact with the mucosa.

Patients were motivated and instructed to use an angled-handle toothbrush (Specialist Implant, Curasept S.p.A., Saronno, Italy), in addition to a standard toothbrush and implant floss. The specific design of the angled handle was intended to facilitate access to areas that are difficult to clean. In patients rehabilitated with full-arch implant-supported prostheses, these areas typically include distal cantilevers and surfaces in direct contact with the mucosa.
