What this Trial Is About
Researchers are evaluating the effectiveness of different cleaning methods for full-arch implant-supported fixed prostheses in patients with complete tooth loss (edentulism). These prostheses can restore chewing, appearance, and speech functions, but biological complications related to poor oral hygiene and plaque buildup can occur within 10 years. The study aims to compare cleaning tools to find the best method for maintaining implant-supported prostheses over time. The study uses a self-controlled, three-phase crossover design where each participant will use three different cleaning tools in sequence: superfloss, interdental brushes, and a water flosser. Each tool will be used for three months, followed by an examination before switching to the next method. This approach allows comparison of cleaning effectiveness for each tool over nine months total. Participants will be assessed for how well each cleaning method removes plaque from the prostheses, measured at the end of each three-month period. The study includes monitoring oral hygiene and plaque levels, with follow-up examinations after each cleaning phase. The total participation time is nine months, during which researchers will measure the plaque cleaning ratio to evaluate each tool's performance and help improve long-term care of implant-supported prostheses.
