Background <p>Dental implant therapy is a highly predictable and widely utilized modality for the rehabilitation of partial and complete edentulism, spanning various configurations including single crowns, fixed dental prostheses, and overdentures. However, diverse surgical, biological, and mechanical complications can occur across all rehabilitation types, potentially compromising clinical outcomes and patient satisfaction. YouTube™ is a widely used source of health-related information due to its accessibility, but the lack of peer review raises concerns regarding the accuracy and completeness of its content. Although previous studies have evaluated YouTube™ videos related to dental implants, those specifically focusing on implant-related complications remain limited. Therefore, this study aimed to critically evaluate the informativeness, quality, and demographic characteristics of YouTube™ videos related to dental implant complications and to assess the information they provide to patients and dental professionals.</p> Methods <p>This study evaluated the informativeness of YouTube™ videos on dental implant complications using a structured assessment framework derived from Newman and Carranza’s Clinical Periodontology and Implantology. Using the keyword “dental implant complications” the first 300 videos were screened, and 139 eligible videos were included. Videos were assessed based on the presence of key complication-related topics defined in the reference textbook. In addition, video duration, number of likes, interaction rate, and audiovisual quality were analyzed.</p> Results <p>Most videos were classified as having a “moderate” level of information, with only 15.1% rated as “very good.” Significant differences were observed in video duration, number of likes, interaction rates, and visual quality across different information levels. Video duration also varied significantly according to the upload source, while audiovisual quality differed based on publication year (<i>p</i> &lt; 0.05).</p> Conclusions <p>The limited informativeness of YouTube™ videos on dental implant complications may contribute to inadequate patient understanding and unrealistic expectations. These findings highlight the need to improve the quality of online patient education and emphasize the role of dental professionals in providing accurate and comprehensive digital health information.</p>
