Impact of an AI-Based Chatbot on Implant Patient Management: RCT

Background: Dental implant therapy is a well-established and predictable procedure for replacing missing teeth, with high long-term survival rates. However, poor oral hygiene remains one of the main modifiable risk factors for peri-implant diseases such as mucositis and peri-implantitis. Objective: The aim of this randomized controlled clinical trial is to evaluate the effectiveness of an artificial intelligence (AI)-based chatbot, developed and validated by dental experts, in improving oral hygiene and clinical outcomes in patients with implant-supported restorations, compared to traditional educational methods such as printed leaflets and dental hygienist sessions. Methods: A total of 110 adult patients rehabilitated with dental implants were randomly assigned to either an AI chatbot intervention group or a control group receiving standard oral hygiene education. The chatbot provides continuous, personalized education and motivation through natural language interaction. Clinical and radiographic parameters, including plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD), and marginal bone loss (MBL), were recorded at baseline and at follow-up visits. Expected outcomes: It is hypothesized that the use of an AI-based chatbot will significantly improve oral hygiene compliance and clinical outcomes compared to conventional methods. Significance: The study aims to demonstrate the potential of AI-assisted patient education in promoting long-term peri-implant health and preventing peri-implant diseases.
